Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a method for adjusting the intake manifold of a vehicle gasoline engine, an electronic device, and a storage medium. Background Technology

[0002] In the modern automotive industry, the design of the engine's intake manifold has a crucial impact on power, fuel economy, and emissions performance. As a vital component of the engine, the cylinder head's design is critical for optimizing the intake manifold tumble ratio. During engine development, engineers need to precisely control the intake manifold tumble ratio to achieve optimal combustion efficiency and emissions performance. However, existing technologies suffer from the following problems:

[0003] (1) When the tumble ratio of the intake manifold does not reach the expected tumble ratio, the cylinder head needs to be re-produced. However, the cylinder head design and development process is time-consuming, which delays the overall engine performance development progress;

[0004] (2) Even after a long development cycle, the re-produced cylinder head cannot guarantee that it will fully meet the performance requirements of the project. It requires multiple design changes and re-producions, which increases the development cost.

[0038] Figure 1 This is a flowchart of a method for adjusting the intake manifold of a vehicle gasoline engine according to one embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0039] Step S10: Obtain the desired tumble ratio, first tumble ratio, preset position, and multiple preset tumble ratio ranges of the gasoline engine intake manifold. The first tumble ratio is used to represent the tumble ratio before the gasoline engine intake manifold is adjusted. The multiple preset tumble ratio ranges include at least the target preset tumble ratio range.

[0040] In step S10, the first tumble ratio is used to represent the initial tumble ratio of the vehicle's gasoline engine intake manifold.

[0041] The aforementioned preset tumble ratio ranges include a target preset tumble ratio range, a first preset tumble ratio range, a second preset tumble ratio range, and a third preset tumble ratio range. The lower limit of the first preset tumble ratio range is greater than the upper limit of the second preset tumble ratio range, the lower limit of the second preset tumble ratio range is greater than the upper limit of the third preset tumble ratio range, and the lower limit of the third preset tumble ratio range is greater than the upper limit of the target preset tumble ratio range. For example, the target preset tumble ratio range is [0, 0.1], the third preset tumble ratio range is (0.1, 0.3], the second preset tumble ratio range is (0.3, 0.5], and the first preset tumble ratio range is (0.5, ∞).

[0042] The aforementioned preset positions are used to indicate the positions in the vehicle's gasoline engine intake manifold that need to be adjusted.

[0043] Step S12: Compare the desired tumble ratio with the first tumble ratio to obtain a first comparison result, wherein the first comparison result is used to determine whether the first tumble ratio is greater than the desired tumble ratio;

[0044] Specifically, the desired tumble ratio is compared with the first tumble ratio to determine whether the first tumble ratio is greater than the desired tumble ratio. The adjustment type of the cylinder head is determined based on the comparison result between the desired tumble ratio and the first tumble ratio.

[0045] Step S14: Calculate the difference between the desired tumble ratio and the first tumble ratio to obtain the first calculation result;

[0046] Step S16: Perform an absolute value operation on the first calculation result to obtain the first absolute value;

[0047] Step S18: Based on the first comparison result, the first absolute value, the preset position, and multiple preset tumble ratio ranges, determine the adjustment strategy for the gasoline engine intake manifold. The adjustment strategy is used to indicate that by adjusting the preset position, the difference between the target tumble ratio and the desired tumble ratio of the gasoline engine intake manifold is adjusted to the target preset tumble ratio range. The target tumble ratio is used to indicate the tumble ratio after the adjustment of the gasoline engine intake manifold is completed.

[0048] In step S18, the above adjustment strategy includes information on the adjustment type, adjustment position, and adjustment size of the cylinder head.

[0049] Specifically, firstly, the desired tumble ratio, first tumble ratio, preset position, and multiple preset tumble ratio ranges of the gasoline engine intake manifold are obtained. Then, the desired tumble ratio is compared with the first tumble ratio to determine if the first tumble ratio is greater than the desired tumble ratio. Based on the comparison result, the cylinder head adjustment method is determined. Next, the difference between the desired tumble ratio and the first tumble ratio is calculated to obtain a first calculation result. The absolute value of the first calculation result is then calculated to obtain a first absolute value. Based on the first absolute value and multiple preset tumble ratio ranges, the adjustment position and adjustment size are determined. Finally, the cylinder head is adjusted according to the adjustment type, adjustment position, and adjustment size so that the difference between the target tumble ratio and the desired tumble ratio of the gasoline engine intake manifold falls within the target preset tumble ratio range.

[0050] Based on steps S10 to S18 above, the desired tumble ratio, first tumble ratio, preset position, and multiple preset tumble ratio intervals of the gasoline engine intake manifold are obtained. The desired tumble ratio is compared with the first tumble ratio to obtain a first comparison result. The difference between the desired tumble ratio and the first tumble ratio is calculated to obtain a first calculation result. The absolute value of the first calculation result is calculated to obtain a first absolute value. Finally, based on the first comparison result, the first absolute value, the preset position, and multiple preset tumble ratio intervals, the adjustment strategy of the gasoline engine intake manifold is determined. This achieves the goal of quickly and accurately adjusting the tumble of the vehicle's gasoline engine intake manifold, thereby reducing manufacturing costs and shortening the manufacturing cycle. This solves the technical problems of long manufacturing cycles and high costs of vehicle gasoline engine intake manifolds in related technologies.

[0051] Optionally, in step S18, determining the adjustment strategy for the gasoline engine intake manifold based on the first comparison result, the first absolute value, the preset position, and multiple preset tumble ratio ranges includes:

[0052] Step S181: Determine the adjustment type of the gasoline engine intake manifold based on the first comparison result;

[0053] Specifically, the desired tumble ratio is compared with the first tumble ratio to determine whether the first tumble ratio is greater than the desired tumble ratio. Based on the comparison result of the desired tumble ratio and the first tumble ratio, the adjustment type of the cylinder head is determined, which includes supplementary processing and reduction processing.

[0054] Step S182: Determine the first adjustment size and first adjustment position of the gasoline engine intake manifold based on the adjustment type, the first absolute value, the preset position, and multiple preset tumble ratio ranges;

[0055] In step S182, the first adjustment dimension is used to indicate the position for the initial adjustment of the gasoline engine intake manifold.

[0056] The aforementioned first adjustment position is used to indicate the dimensions for the initial adjustment of the gasoline engine intake manifold.

[0057] Specifically, it is determined which of the multiple preset tumble ratio intervals the first absolute value falls into, and the first adjustment size and the first adjustment position are determined based on the adjustment type and the preset tumble ratio interval in which the first absolute value is located.

[0058] Step S183: Adjust the gasoline engine intake manifold according to the adjustment type, the first adjustment size, and the first adjustment position to obtain the adjusted gasoline engine intake manifold.

[0059] Step S184: Detect the tumble ratio of the adjusted gasoline engine intake manifold to obtain the second tumble ratio;

[0060] Specifically, firstly, the cylinder head intake valves are removed; then, the cylinder head of the gasoline engine intake manifold is adjusted according to the adjustment type, first adjustment size, and first adjustment position to obtain the adjusted gasoline engine intake manifold; finally, the cylinder head intake manifold is cleaned, the intake valves are installed, and the cylinder head intake manifold is tested again to obtain the second tumble ratio.

[0061] Step S185: Determine the adjustment strategy based on the adjustment type, the second tumble ratio, the desired tumble ratio, the preset position, and multiple preset tumble ratio ranges.

[0062] Specifically, the adjustment size and adjustment position for readjustment are determined based on the second tumble ratio, the desired tumble ratio, the preset position, and multiple preset tumble ratio ranges. The intake manifold of the gasoline engine is readjusted according to the adjustment type and the readjustment size and adjustment position, so that the difference between the target tumble ratio and the desired tumble ratio is within the target preset tumble ratio range.

[0063] Based on steps S181 to S185 above, the method of determining the adjustment type of the gasoline engine intake manifold based on the first comparison result is adopted. First, the first adjustment size and first adjustment position of the gasoline engine intake manifold are determined based on the adjustment type, the first absolute value, the preset position, and multiple preset tumble ratio ranges. Then, the gasoline engine intake manifold is adjusted according to the adjustment type, the first adjustment size, and the first adjustment position to obtain the adjusted gasoline engine intake manifold. Next, the tumble ratio of the adjusted gasoline engine intake manifold is detected to obtain the second tumble ratio. Finally, the adjustment strategy is determined based on the adjustment type, the second tumble ratio, the desired tumble ratio, the preset position, and multiple preset tumble ratio ranges. The target tumble ratio of the gasoline engine intake manifold is changed directly on the basis of the existing engine cylinder head by adjusting the gasoline engine intake manifold. This saves the time of repeated processing of the blower box, repeated trial production and processing of the cylinder head, and reduces the cylinder head trial production cost.

[0064] Optionally, in step S181, determining the adjustment type of the gasoline engine intake manifold based on the first comparison result includes:

[0065] Step S1811: In response to determining that the first tumble ratio is greater than the expected tumble ratio through comparison results, the adjustment type of the gasoline engine intake manifold is determined to be a reduction process.

[0066] Specifically, if the comparison results determine that the first tumble ratio is greater than the expected tumble ratio, the adjustment type of the gasoline engine intake manifold is determined to be a reduction treatment.

[0067] Step S1812: In response to the comparison result determining that the first tumble ratio is less than the expected tumble ratio, the adjustment type of the gasoline engine intake manifold is determined to be supplementary processing.

[0068] Specifically, if the comparison results determine that the first tumble ratio is less than the expected tumble ratio, the adjustment type of the gasoline engine intake manifold is determined to be a reduction treatment.

[0069] Based on the above steps S1811 to S1812, in response to determining that the first tumble ratio is greater than the expected tumble ratio through comparison results, the adjustment type of the gasoline engine intake manifold is determined to be a reduction process; in response to determining that the first tumble ratio is less than the expected tumble ratio through comparison results, the adjustment type of the gasoline engine intake manifold is determined to be a supplementary process. By directly comparing the first tumble ratio with the expected tumble ratio, it is possible to quickly determine whether adjustment is needed and if so, reducing the time for trial and error and repeated manufacturing, and improving the accuracy of the adjustment.

[0070] Optionally, in step S182, the plurality of preset tumble ratio intervals further include a first preset tumble ratio interval, and the preset positions include a first position, a second position, and a third position. Determining the first adjustment dimension and the first adjustment position of the gasoline engine intake manifold based on the adjustment type, the first absolute value, the preset position, and the plurality of preset tumble ratio intervals includes:

[0071] Step S1821: In response to the first absolute value being within the first preset tumble ratio range and the adjustment type being reduction processing, the adjustment position is determined to be any position among the preset positions, and the adjustment dimension is determined to be the first thickness value.

[0072] In step S1822, in response to the first absolute value being within the first preset tumble ratio range and the adjustment type being supplementary processing, the adjustment position is determined to be either the second position or the third position, and the adjustment dimension is determined to be the first thickness value.

[0073] Specifically, Figure 2A This is a schematic diagram of a method for adjusting the intake manifold of a vehicle gasoline engine according to one embodiment of the present invention. Figure 2A A top view of the tangential airway, such as Figure 2A As shown, ① indicates the first position in the preset positions, ④ indicates the air intake port, ⑥ indicates the valve seat, and ⑧ indicates the cylinder diameter. Figure 2BThis is a schematic diagram of another method for adjusting the intake manifold of a vehicle gasoline engine according to one embodiment of the present invention. Figure 2B This is a side view of the tangential airway, as shown below. Figure 2B As shown, ② indicates the second position in the preset positions, ③ indicates the third position in the preset positions, ④ indicates the air intake port, ⑤ indicates the valve guide, ⑥ indicates the valve seat, and ⑦ indicates the air passage tool correction position.

[0074] Specifically, if the comparison results determine that the first tumble ratio is greater than the expected tumble ratio, and the first absolute value is within the first preset tumble ratio range, a reduction process is performed on any of the preset positions, where the reduction thickness is the first thickness value. If the comparison results determine that the first tumble ratio is less than the expected tumble ratio, and the first absolute value is within the first preset tumble ratio range, a supplementary process is performed on any of the second and third positions, where the supplementary thickness is the first thickness value. For example, if the first preset tumble ratio range is (0.5, ∞), when the first tumble ratio is greater than the expected tumble ratio, and the absolute value of the difference between the first tumble ratio and the expected tumble ratio is greater than 0.5, a reduction process is performed on any of the preset positions, where the reduction thickness is the first thickness value. Figure 2A and Figure 2B A reduction process is performed at any of the preset positions, with a reduction thickness of 1 mm. Similarly, when the first tumble ratio is less than the desired tumble ratio, and the absolute value of the difference between the first tumble ratio and the desired tumble ratio is greater than 0.5, a supplementary process is performed at any of the second and third positions, with a supplementary thickness of 1 mm. Specifically, an aluminum repair agent with a thickness of 1 mm is added to the airway wall.

[0075] Based on the above steps S1821 to S1822, in response to the first absolute value being within the first preset tumble ratio range and the adjustment type being reduction processing, the adjustment position is determined to be any position among the preset positions, and the adjustment dimension is determined to be the first thickness value; in response to the first absolute value being within the first preset tumble ratio range and the adjustment type being supplementary processing, the adjustment position is determined to be any position among the second position and the third position, and the adjustment dimension is determined to be the first thickness value. Once it is determined that adjustment is needed, the preset position is directly reduced or supplemented without a complex trial-and-error process, which shortens the adjustment time. Furthermore, by determining the thickness of the reduction or supplementation, the manufacturing process is simplified, and the efficiency of adjusting the tumble ratio of the gasoline engine intake manifold is improved.

[0076] Optionally, in step S185, determining the adjustment strategy based on the adjustment type, the second tumble ratio, the desired tumble, the preset position, and multiple preset tumble ratio ranges includes:

[0077] Step S1851: Calculate the difference between the desired tumble ratio and the second tumble ratio to obtain the second calculation result;

[0078] Step S1852: Determine the second adjustment dimension and the second adjustment position of the gasoline engine intake manifold based on the second calculation result, the preset position, and multiple preset tumble ratio ranges;

[0079] Step S1853: Adjust the gasoline engine intake manifold based on the adjustment type, the second adjustment size, and the second adjustment position until the difference between the target tumble ratio and the desired tumble ratio is adjusted to the target preset tumble ratio range.

[0080] Specifically, the cylinder head of the gasoline engine intake manifold is adjusted according to the adjustment type, first adjustment size, and first adjustment position. After obtaining the adjusted intake manifold, the cylinder head intake manifold is cleaned, the intake valves are installed, and the tumble ratio is tested again to obtain the second tumble ratio. The difference between the desired tumble ratio and the second tumble ratio is calculated to obtain the second calculation result. Based on the second calculation result, the preset position, and multiple preset tumble ratio ranges, the second adjustment size and the second adjustment position for adjusting the gasoline engine intake manifold are determined. The intake manifold is then adjusted again according to the adjustment type, the second adjustment size, and the second adjustment position until the difference between the target tumble ratio and the desired tumble ratio is adjusted to the target preset tumble ratio range.

[0081] Based on steps S1851 to S1853 above, the difference between the desired tumble ratio and the second tumble ratio is first calculated to obtain the second calculation result. Then, based on the second calculation result, the preset position, and multiple preset tumble ratio ranges, the second adjustment dimension and the second adjustment position of the gasoline engine intake manifold are determined. Finally, the gasoline engine intake manifold is adjusted based on the adjustment type, the second adjustment dimension, and the second adjustment position until the difference between the target tumble ratio and the desired tumble ratio is adjusted to the target preset tumble ratio range. This allows for flexible determination of the adjustment dimension and position, thereby quickly and accurately adjusting the gasoline engine intake manifold, reducing costs during cylinder head prototyping, and improving production efficiency.

[0082] Optionally, in step S1852, the plurality of preset tumble ratio intervals further include a second preset tumble ratio interval, and the preset positions include a second position and a third position. Determining the second adjustment dimension and the second adjustment position of the gasoline engine intake manifold based on the second calculation result, the preset positions, and the plurality of preset tumble ratio intervals includes:

[0083] Step S201: Perform an absolute value operation on the second calculation result to obtain the second absolute value;

[0084] In step S202, in response to the second absolute value being within the second preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the second thickness value.

[0085] Specifically, the absolute value of the second calculation result is calculated to obtain the second absolute value; if the second absolute value is within the second preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the second thickness value.

[0086] Furthermore, if the second tumble ratio is greater than the desired tumble ratio, and the second absolute value is within the second preset tumble ratio range, a reduction process is performed on either position two or position three, where the reduction thickness is the second thickness value, which is less than the first thickness value. If the second tumble ratio is less than the desired tumble ratio, and the second absolute value is within the second preset tumble ratio range, a supplementary process is performed on either position two or position three, where the supplementary thickness is the second thickness value, which is less than the first thickness value. For example, if the second preset tumble ratio range is (0.3, 0.5], the second tumble ratio is less than the desired tumble ratio, and the second absolute value is within the third preset tumble ratio range, the second adjustment position is either position two or position three. Figure 2B As shown, if the second position is selected, the repair direction is to add 0.5mm of aluminum repair agent upwards onto the airway wall. Alternatively, the third position can be selected, with the repair direction being to add 0.5mm of aluminum repair agent onto the airway wall. If the second tumble ratio is greater than the desired tumble ratio, and the second absolute value is within the second preset tumble ratio range, the second adjustment position can be either the second or third position. Figure 2B As shown, if the second position is selected, the airway wall is reduced by 0.5 mm; the third position can also be selected to reduce the airway wall by 0.5 mm.

[0087] Based on the above steps S201 to S202, the absolute value of the second calculation result is calculated to obtain the second absolute value; in response to the second absolute value being within the second preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the second thickness value. By determining the precise adjustment position and dimension, trial and error and rework can be reduced, adjustment efficiency can be improved, and manufacturing costs can be reduced.

[0088] Optionally, in step S1852, the plurality of preset tumble ratio intervals further include a third preset tumble ratio interval. Determining the second adjustment dimension and the second adjustment position of the gasoline engine intake manifold based on the second calculation result, the preset position, and the plurality of preset tumble ratio intervals includes:

[0089] Step S203: In response to the second absolute value being within the third preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the third thickness value, wherein the third thickness value is less than the second thickness value. Specifically, the absolute value of the second calculation result is calculated to obtain the second absolute value; if the second absolute value is within the third preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the third thickness value, wherein the third thickness value is less than the second thickness value.

[0090] Furthermore, if the second tumble ratio is greater than the desired tumble ratio, and the second absolute value is within the third preset tumble ratio range, a reduction process is performed on either the second or third position, where the reduction thickness is the third thickness value, which is less than the second thickness value. If the second tumble ratio is less than the desired tumble ratio, and the second absolute value is within the third preset tumble ratio range, a supplementary process is performed on either position two or position three, where the supplementary thickness is the third thickness value, which is less than the second thickness value. For example, the third preset tumble ratio range is (0.1, 0.3). If the second tumble ratio is less than the desired tumble ratio, and the second absolute value is within the third preset tumble ratio range, the second adjustment position is either the second or third position. Figure 2B As shown, if the second position is selected, the repair direction is to add 0.1mm of aluminum repair agent upwards onto the airway wall. Alternatively, the third position can be selected, with the repair direction being to add 0.1mm of aluminum repair agent onto the airway wall. If the second tumble ratio is greater than the desired tumble ratio, and the second absolute value is within the third preset tumble ratio range, the second adjustment position can be either the second or third position. Figure 2B As shown, if the second position is selected, the airway wall is reduced to 0.1 mm; the third position can also be selected to reduce the airway wall by 0.1 mm.

[0091] Based on the above step S203, in response to the second absolute value being within the third preset tumble ratio range, the second adjustment position is determined to be either the second position or the third position, and the second adjustment dimension is determined to be the third thickness value, wherein the third thickness value is less than the second thickness value. For different tumble ratio difference ranges, different adjustment positions and dimensions are selected to make the adjustment more flexible. Furthermore, by determining precise adjustment positions and dimensions, trial and error and rework can be reduced, adjustment efficiency can be improved, and manufacturing costs can be reduced.

[0092] Optionally, the multiple preset tumble ratio ranges further include: a first preset tumble ratio range, a second preset tumble ratio range, and a third preset tumble ratio range, wherein the lower limit of the first preset tumble ratio range is greater than the upper limit of the second preset tumble ratio range, the lower limit of the second preset tumble ratio range is greater than the upper limit of the third preset tumble ratio range, and the lower limit of the third preset tumble ratio range is greater than the upper limit of the target preset tumble ratio range.

[0093] Specifically, the multiple preset tumble ratio intervals include a target preset tumble ratio interval, a first preset tumble ratio interval, a second preset tumble ratio interval, and a third preset tumble ratio interval. The lower limit of the first preset tumble ratio interval is greater than the upper limit of the second preset tumble ratio interval, the lower limit of the second preset tumble ratio interval is greater than the upper limit of the third preset tumble ratio interval, and the lower limit of the third preset tumble ratio interval is greater than the upper limit of the target preset tumble ratio interval. For example, the target preset tumble ratio interval is [0, 0.1], the third preset tumble ratio interval is (0.1, 0.3], the second preset tumble ratio interval is (0.3, 0.5], and the first preset tumble ratio interval is (0.5, ∞).
