[0042] The above-mentioned preset position is used to indicate the position in the intake duct of the vehicle gasoline engine that needs to be adjusted.

[0043] Step S12, comparing the expected 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 expected tumble ratio;

[0044] Specifically, the expected tumble ratio is compared with the first tumble ratio to determine whether the first tumble ratio is greater than the expected tumble ratio.

[0050] Based on the above steps S10 to S18, the expected tumble ratio, the first tumble ratio, the preset position and multiple preset tumble ratio intervals of the gasoline engine intake duct are obtained, the expected tumble ratio is compared with the first tumble ratio to obtain a first comparison result, the difference between the expected tumble ratio and the first tumble ratio is calculated to obtain a first calculation result; the first calculation result is calculated to obtain an absolute value 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 duct is determined, so as to achieve the purpose of quickly and accurately adjusting the tumble of the vehicle gasoline engine intake duct, thereby realizing the technical effect of reducing manufacturing costs and shortening manufacturing cycles, and further solving the technical problems of long manufacturing cycles and high costs of vehicle gasoline engine intake ducts in related technologies.

[0051] Optionally, in step S18, determining an adjustment strategy of the gasoline engine intake port based on the first comparison result, the first absolute value, the preset position and a plurality of preset tumble ratio intervals includes:

[0052] Step S181, determining the adjustment type of the gasoline engine intake duct based on the first comparison result;

[0054] Step S182, determining a first adjustment size and a first adjustment position of the gasoline engine intake port based on the adjustment type, the first absolute value, the preset position and a plurality of preset tumble ratio intervals;

[0055] In step S182, the first adjustment size is used to indicate the position of the first adjustment of the gasoline engine intake duct.

[0056] The first adjustment position is used to indicate the size of the first adjustment to the gasoline engine intake duct.

[0057] Specifically, it is determined which preset tumble ratio interval the first absolute value is in among multiple preset tumble ratio intervals, and the first adjustment size and the first adjustment position are determined according to the adjustment type and the preset tumble ratio interval in which the first absolute value is located.

[0058] Step S183, adjusting the gasoline engine intake duct according to the adjustment type, the first adjustment size and the first adjustment position to obtain an adjusted gasoline engine intake duct;

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

[0067] Step S1812, in response to determining through the comparison result that the first tumble ratio is less than the expected tumble ratio, determining that the adjustment type of the gasoline engine intake port is supplementary processing.

[0068] Specifically, if it is determined through the comparison result that the first tumble ratio is less than the expected tumble ratio, the adjustment type of the gasoline engine intake port is determined to be a reduction process.

[0069] Based on the above steps S1811 to S1812, in response to determining through the comparison results that the first tumble ratio is greater than the expected tumble ratio, the adjustment type of the gasoline engine intake duct is determined to be reduction processing; in response to determining through the comparison results that the first tumble ratio is less than the expected tumble ratio, the adjustment type of the gasoline engine intake duct is determined to be supplementary processing. By directly comparing the first tumble ratio with the expected tumble ratio, it is possible to quickly determine whether adjustment is needed and how much adjustment is needed, thereby 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, the preset positions include a first position, a second position, and a third position, and determining a first adjustment size and a first adjustment position of the gasoline engine intake port 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 in a first preset tumble ratio interval and the adjustment type being a reduction process, determining the adjustment position to be any one of the preset positions, and determining the adjustment size to be a first thickness value;

[0072] Step S1822, in response to the first absolute value being in the first preset tumble ratio interval and the adjustment type being supplementary processing, determining the adjustment position to be any one of the second position and the third position, and determining the adjustment size to be the first thickness value.

[0074] Specifically, if it is determined through the comparison result that the first tumble ratio is greater than the expected tumble ratio, and the first absolute value is within the first preset tumble ratio interval, a reduction process is performed on any position in the preset position, wherein the reduced thickness is the first thickness value. If it is determined through the comparison result that the first tumble ratio is less than the expected tumble ratio, and the first absolute value is within the first preset tumble ratio interval, a supplementary process is performed on any position in the second position and the third position, wherein the supplemented thickness is the first thickness value. For example, the first preset tumble ratio interval 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, the Figure 2A and Figure 2B A reduction process is performed on any of the preset positions, wherein the thickness of the reduction is 1 mm.

After obtaining the adjusted gasoline engine intake duct, the cylinder head intake duct is cleaned, the intake valve is installed, and the cylinder head intake duct is tested for tumble ratio again to obtain a second tumble ratio.

[0086] Furthermore, if the second tumble ratio is greater than the expected tumble ratio, and the second absolute value is in the second preset tumble ratio interval, a reduction process is performed on any position between position two and position three, wherein the reduced thickness is the second thickness value, and the second thickness value is less than the first thickness value.
