It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0025] The following is a brief explanation of the terms used in this application.

[0026] Fuel injection quantity change rate: The change in fuel injection quantity over a certain period of time.

[0027] Regeneration during driving: This involves increasing the temperature of the engine exhaust flow by adding external energy (i.e., the amount of fuel injected afterward), so that the exhaust temperature reaches the ignition temperature of the particulate matter, thereby burning off the particulate matter in the filter and achieving the purpose of regeneration.

[0028] The related technologies mentioned in the background section have at least the following technical problems:

[0029] Sudden increases in engine load can cause hydrocarbon leaks; stopping the vehicle during regeneration can also cause hydrocarbon leaks, as can suddenly accelerating after descending a long slope during regeneration. The greater the hydrocarbon leak, the higher the vehicle's fuel consumption.

[0030] Therefore, this application proposes a method for handling engine hydrocarbon leakage. This method controls the subsequent fuel injection quantity by monitoring the rate of change of fuel injection quantity. Specifically, when the rate of change of fuel injection quantity is enabled, the subsequent fuel injection quantity is reduced to decrease the engine's hydrocarbon leakage. Enabling the rate of change of fuel injection quantity requires simultaneously meeting the following three conditions: the engine must be in regeneration mode; the cumulative duration of the engine fuel quantity being greater than or equal to a first fuel quantity threshold is greater than or equal to a first duration threshold, or the cumulative duration of the engine fuel quantity being less than or equal to a second fuel quantity threshold is greater than or equal to a second duration threshold, wherein the first fuel quantity threshold is greater than the second fuel quantity threshold; and the difference between the current fuel injection quantity and the previous fuel injection quantity is greater than or equal to a preset value.

[0031] In one embodiment, the method for handling engine hydrocarbon leakage can be applied in an application scenario. Figure 1 This is a schematic diagram illustrating an application scenario of the engine control method provided in the embodiments of this application, such as... Figure 1 As shown, the method for handling engine hydrocarbon leakage can be applied to an engine hydrocarbon leakage handling system, which may include a logic judgment module and a control module.

[0032] In this application scenario, the logic judgment module determines whether the engine's fuel injection rate change is enabled by the engine's current operating mode, fuel quantity, and fuel injection quantity. If the engine's fuel injection rate change is enabled, an enable signal is sent to the control module to indicate that the engine's fuel injection rate change is enabled. This allows the control module to control the engine to reduce the amount of fuel injected after injection based on the enable signal, thereby reducing hydrocarbon leakage from the engine.

[0033] In the above application scenario, when the logic judgment module determines whether the engine's fuel injection rate change is enabled based on the engine's current operating mode, fuel quantity, and fuel injection quantity, it can first determine whether the engine is in regeneration mode. If the engine is in regeneration mode, it determines whether the engine fuel quantity is greater than or equal to a first fuel quantity threshold, or whether the engine fuel quantity is less than or equal to a second fuel quantity threshold. If the engine fuel quantity is greater than or equal to the first fuel quantity threshold, a timer is triggered to start counting when the engine fuel quantity is greater than or equal to the first fuel quantity threshold to obtain the first accumulated duration and determine the second... If the cumulative duration is greater than or equal to a first duration threshold, or if the engine fuel quantity is less than or equal to a second fuel quantity threshold, a timer is triggered to start counting to obtain a second cumulative duration, and it is determined whether the second cumulative duration is greater than or equal to the second duration threshold. If the first cumulative duration is greater than or equal to the first duration threshold, or the second cumulative duration is greater than or equal to the second duration threshold, then it is determined whether the difference in fuel injection quantity between the current engine fuel injection quantity and the previous engine fuel injection quantity is greater than or equal to a preset value. If the difference in fuel injection quantity is greater than or equal to the preset value, then it is determined that the engine fuel injection quantity change rate is enabled.

[0034] In the above application scenarios, if the engine is not in regeneration mode, or the first cumulative duration of the engine fuel quantity is greater than or equal to the first fuel quantity threshold and is greater than or equal to the first duration threshold, or the second cumulative duration of the engine fuel quantity is less than or equal to the second fuel quantity threshold and is greater than or equal to the second duration threshold, or the difference between the engine fuel injection quantity at the current moment and the engine fuel injection quantity at the previous moment is less than a preset value, then it is determined that the engine fuel injection quantity change rate is not enabled.

[0035] In light of the above scenarios, the technical solution of the engine hydrocarbon leakage treatment method provided in this application will be described in detail below through several specific embodiments.

[0036] This application provides a method for handling hydrocarbon leakage in an engine. Figure 2 This is a schematic flowchart of the engine hydrocarbon leakage handling method provided in the embodiments of this application, as shown below. Figure 2 As shown, the method includes the following steps:

[0037] S201: Obtain the engine's current operating mode, engine oil level, and engine fuel injection quantity.

[0038] Specifically, it can monitor the engine's operating mode, engine oil level, and engine fuel injection quantity in real time.

[0039] Optionally, the engine's operating mode at the current moment can be determined by the corresponding parameters of the engine; the engine oil level can be determined by the dipstick or by the oil level monitoring sensor; the engine fuel injection quantity can be determined by the intake air volume and engine speed, etc.

[0040] S202: Based on the operating mode, engine oil quantity, and engine fuel injection quantity, determine whether the engine fuel injection quantity change rate is enabled.

[0041] Specifically, the fuel injection quantity change rate enable is used to indicate that the fuel injection quantity change rate meets certain conditions, which can be determined by the operating mode, engine oil quantity, and engine fuel injection quantity.

[0042] S203: In response to the fuel injection quantity change rate enable, controls the reduction of the engine's post-injection quantity to reduce engine hydrocarbon leakage.

[0043] Specifically, when determining the enable of the fuel injection quantity change rate, it can be assumed that the engine's operating mode, engine oil quantity, and engine fuel injection quantity have all reached the desired conditions. Therefore, by controlling the reduction of the engine's post-injection quantity, the engine's hydrocarbon leakage can be reduced, thereby solving the problem of excessive vehicle fuel consumption caused by excessive engine hydrocarbon leakage.

[0044] The method for handling engine hydrocarbon leakage disclosed in this application controls the engine's post-injection fuel quantity by monitoring the rate of change of the engine's fuel injection quantity. That is, by monitoring the engine's current operating mode, engine fuel quantity, and engine fuel injection quantity, it is determined whether the rate of change of the fuel injection quantity is enabled. If the rate of change of the fuel injection quantity is enabled, the engine's post-injection fuel quantity can be reduced to decrease the engine's hydrocarbon leakage, thereby solving the problem of increased vehicle fuel consumption caused by engine hydrocarbon leakage.

[0045] In one embodiment, determining whether the engine's fuel injection rate change is enabled based on the operating mode, engine fuel quantity, and engine fuel injection quantity includes: determining that the engine's fuel injection rate change is enabled in response to the simultaneous fulfillment of a first condition, a second condition, and a third condition; and determining that the engine's fuel injection rate change is not enabled in response to the simultaneous failure to fulfill the first condition, the second condition, and the third condition. The first condition is that the operating mode is a regeneration mode; the second condition is that the engine fuel quantity is greater than or equal to a first fuel quantity threshold, and the first cumulative duration is greater than or equal to a first duration threshold, or the engine fuel quantity is less than or equal to a second fuel quantity threshold, and the second cumulative duration is greater than or equal to a second duration threshold, wherein the first fuel quantity threshold is greater than the second fuel quantity threshold; and the third condition is that the difference between the engine fuel injection quantity at the current moment and the engine fuel injection quantity at the previous moment is greater than a preset value.

[0046] Specifically, analysis of a large amount of data revealed that when the engine is in regenerative mode, it often experiences a period of operation with a fuel quantity greater than or equal to the first fuel quantity threshold, leading to a sudden increase in load and causing a large amount of hydrocarbon leakage. Alternatively, if the engine is idle or descending a long slope (where the fuel quantity is less than or equal to the second fuel quantity threshold) for a certain period of time, it will also cause a sudden increase in load and hydrocarbon leakage. Therefore, it is necessary to simultaneously use the first, second, and third conditions to determine whether the fuel injection quantity change rate is enabled in order to determine whether hydrocarbon leakage has occurred in the engine.

[0047] In one alternative implementation, enabling the fuel injection rate change requires simultaneous fulfillment of a first condition, a second condition, and a third condition to determine whether hydrocarbon leakage has occurred in the engine. Specifically, the engine must be in regeneration mode, and the first cumulative duration of the engine fuel quantity being greater than or equal to a first fuel quantity threshold must be greater than or equal to a first duration threshold, or the second cumulative duration of the engine fuel quantity being less than or equal to a second fuel quantity threshold must be greater than or equal to a second duration threshold. Furthermore, the difference between the engine fuel injection quantity at the current moment and the engine fuel injection quantity at the previous moment must be greater than a preset value. Under these conditions, the fuel injection rate change is considered enabled, indicating hydrocarbon leakage in the engine. Therefore, by reducing the subsequent fuel injection quantity, hydrocarbon leakage can be reduced, thus resolving the issue of increased vehicle fuel consumption caused by engine hydrocarbon leakage.

[0048] Optionally, if any one of the first, second, and third conditions is not met, it is considered that the rate of change of fuel injection quantity of the engine is not enabled under this condition. Therefore, it can be determined that the current hydrocarbon leakage of the engine has little impact on the vehicle's fuel consumption. Thus, under this condition, the post-injection quantity of the engine does not need to be reduced.

[0049] In one embodiment, the method further includes: triggering a timer to start timing when the engine oil level is greater than or equal to a first oil level threshold to obtain a first cumulative duration; or triggering a timer to start timing when the engine oil level is less than or equal to a second oil level threshold to obtain a second cumulative duration.

[0050] Specifically, when determining the engine oil level, it can first be determined whether the current engine oil level is greater than or equal to a first oil level threshold, or whether the current engine oil level is less than or equal to a second oil level threshold. If the current engine oil level is greater than or equal to the first oil level threshold, a timer is triggered to start counting from the current moment to obtain a first cumulative duration; or if the current engine oil level is less than or equal to the second oil level threshold, a timer is triggered to start counting from the current moment to obtain a second cumulative duration.

[0051] Optionally, the end time of the first cumulative duration can be the time when the first duration threshold is reached, and the end time of the second cumulative duration can be the time when the second duration threshold is reached.

[0052] Optionally, by determining the first cumulative duration or the second cumulative duration, the enable judgment of the subsequent fuel injection quantity change rate of the engine can be realized. When the fuel injection quantity change rate is enabled, the subsequent fuel injection quantity of the engine can be reduced to reduce hydrocarbon leakage, thereby solving the problem of increased vehicle fuel consumption caused by hydrocarbon leakage of the engine.

[0053] In one embodiment, the method further includes: triggering a timer freeze when the engine oil level is less than a first oil level threshold and greater than a second oil level threshold.

[0054] Specifically, once the engine oil level is detected to be less than the first oil level threshold and greater than the second oil level threshold, the timer is immediately frozen to improve the accuracy of the first and second cumulative durations. This enables the judgment of the subsequent fuel injection rate change of the engine. When the fuel injection rate change is enabled, the subsequent fuel injection of the engine is reduced to reduce hydrocarbon leakage. This solves the problem of increased fuel consumption caused by hydrocarbon leakage in the engine.

[0055] In one optional implementation, the engine oil level being less than a first oil level threshold and greater than a second oil level threshold can include the following two cases:

[0056] In one scenario, if the engine oil level is detected to be less than the first oil level threshold but greater than the second oil level threshold at the current moment, it is considered that the hydrocarbon leakage of the engine has not affected the vehicle's fuel consumption at the current moment. Therefore, the timer can be frozen and the engine oil level can continue to be monitored until the engine oil level is greater than or equal to the first oil level threshold or less than or equal to the second oil level threshold, at which point the timer can be triggered to start counting.

[0057] Another scenario is that at the current moment, the engine oil level is greater than or equal to a first oil level threshold. At a later moment, the engine oil level is less than the first oil level threshold but greater than a second oil level threshold, and the duration between the current moment and that later moment is less than a first cumulative duration. In this case, it is considered that the engine's hydrocarbon leakage has not affected the vehicle's fuel consumption during this period. Alternatively, at the current moment, the engine oil level is less than or equal to a second oil level threshold. At a later moment, the engine oil level is less than the first oil level threshold but greater than the second oil level threshold, and the duration between the current moment and that later moment is less than a second cumulative duration. In this case, it is considered that the engine's hydrocarbon leakage has not affected the vehicle's fuel consumption during this period. Engine oil level monitoring can continue until the engine oil level is greater than or equal to the first oil level threshold or less than or equal to the second oil level threshold, at which point the timer is triggered to restart.

[0058] In one embodiment, the method further includes: triggering a timer to be reset when the first accumulated duration is greater than or equal to a first duration threshold, or when the second accumulated duration is greater than or equal to a second duration threshold.

[0059] Specifically, if the first cumulative duration is greater than or equal to the first duration threshold, or the second cumulative duration is greater than or equal to the second duration threshold, then it is considered that the hydrocarbon leakage of the engine has affected the vehicle's fuel consumption. Therefore, there is no need to continue monitoring the subsequent engine oil level, which can trigger the timer to be reset, thus avoiding affecting the cumulative duration when monitoring the engine oil level for the next time. Therefore, the accuracy of the cumulative duration when monitoring the engine oil level for the next time can be improved.

[0060] In one alternative implementation, since different vehicle models have different performance, the corresponding electronic control data can be modified according to the actual vehicle performance, such as setting fuel level threshold, duration threshold, difference threshold, etc., to meet the actual needs of different vehicle models.

[0061] The method for handling engine hydrocarbon leakage in this application determines three judgment conditions based on the engine's regeneration mode, engine oil quantity, and engine fuel injection quantity. When the rate of change of engine fuel injection quantity simultaneously meets these three judgment conditions, it is considered that the rate of change of engine fuel injection quantity is enabled, that is, the engine has excessive hydrocarbon leakage. Therefore, by controlling the reduction of the engine's post-injection quantity, the purpose of reducing engine hydrocarbon leakage can be achieved, thereby solving the problem of increased vehicle fuel consumption caused by hydrocarbon leakage due to sudden increase in engine load.

[0062] This application also provides an apparatus for treating engine hydrocarbon leakage.

Figure 3 As shown, the engine hydrocarbon leakage treatment device 300 includes:

[0063] The acquisition module 301 is used to acquire the engine's current operating mode, engine oil quantity, and engine fuel injection quantity.

[0064] The determination module 302 is used to determine whether the rate of change of engine fuel injection quantity is enabled based on the operating mode, engine oil quantity, and engine fuel injection quantity.

[0065] Control module 303 is used to control the reduction of the engine's post-injection quantity in response to the fuel injection quantity change rate enable, so as to reduce the engine's hydrocarbon leakage.

[0066] Optionally, the determining module determines whether the engine's fuel injection rate change is enabled based on the operating mode, engine fuel quantity, and engine fuel injection quantity in the following manner: In response to the simultaneous fulfillment of the first, second, and third conditions, the engine's fuel injection rate change is enabled; in response to the failure to simultaneously fulfill the first, second, and third conditions, the engine's fuel injection rate change is disabled. The first condition is that the operating mode is regeneration mode; the second condition is that the first cumulative duration of the engine fuel quantity being greater than or equal to a first fuel quantity threshold is greater than or equal to a first duration threshold, or the second cumulative duration of the engine fuel quantity being less than or equal to a second fuel quantity threshold is greater than or equal to a second duration threshold, wherein the first fuel quantity threshold is greater than the second fuel quantity threshold; the third condition is that the difference between the engine fuel injection quantity at the current moment and the engine fuel injection quantity at the previous moment is greater than a preset value.

[0067] Optionally, the engine hydrocarbon leakage treatment device 300 further includes a treatment module (not shown), which is used to trigger a timer to start timing when the engine oil level is greater than or equal to a first oil level threshold to obtain a first cumulative duration; or, to trigger a timer to start timing when the engine oil level is less than or equal to a second oil level threshold to obtain a second cumulative duration.

[0068] Optionally, the processing module is also used to trigger a timer freeze when the engine oil level is less than a first oil level threshold and greater than a second oil level threshold.

[0069] Optionally, the processing module is also configured to trigger the timer to be cleared when the first accumulated duration is greater than or equal to the first duration threshold, or when the second accumulated duration is greater than or equal to the second duration threshold.
