during sudden increases in engine load, hydrocarbon leakage may occur; the vehicle is stopped in the running regeneration process to cause hydrocarbon leakage, or suddenly accelerated after going down a long slope in the running regeneration process to cause hydrocarbon leakage. And the greater the hydrocarbon leakage, the higher the fuel consumption of the vehicle.
Therefore, the application provides a treatment method for engine hydrocarbon leakage, which controls the post-injection quantity of the engine by monitoring the injection quantity change rate, namely, controls the post-injection quantity of the engine to be reduced when the injection quantity change rate is enabled so as to reduce the hydrocarbon leakage of the engine. The fuel injection amount change rate enabling needs to satisfy the following three conditions simultaneously: the engine needs to be in a regeneration mode; the accumulated time length of the engine oil quantity larger than or equal to the first oil quantity threshold value is larger than or equal to the first time length threshold value, or the accumulated time length of the engine oil quantity smaller than or equal to the second oil quantity threshold value is larger than or equal to the second time length threshold value, wherein the first oil quantity threshold value is larger than the second oil quantity threshold value; the difference between the current fuel injection quantity of the engine and the fuel injection quantity at the previous moment is larger than or equal to a preset value.
In one embodiment, the engine hydrocarbon leakage treatment method may be applied in an application scenario. Fig. 1 is a schematic diagram of an application scenario of a control method of an engine according to an embodiment of the present application, where as shown in fig. 1, the method for processing hydrocarbon leakage of the engine may be applied to a system for processing hydrocarbon leakage of the engine, and the system for processing hydrocarbon leakage of the engine may include a logic judgment module and a control module.
In the application scene, the logic judging module judges whether the fuel injection quantity change rate of the engine is enabled or not through the running mode of the engine at the current moment, the engine fuel quantity and the engine fuel injection quantity, if the fuel injection quantity change rate of the engine is enabled, an enabling signal for indicating the fuel injection quantity change rate enabling of the engine is sent to the control module, so that the control module controls the post fuel injection quantity of the engine to be reduced according to the enabling signal, and the hydrocarbon leakage of the engine can be reduced.
In the above application scenario, the logic judging module may first judge whether the engine is in the regeneration mode when judging whether the fuel injection quantity change rate of the engine is enabled by the running mode of the engine at the current time, the engine fuel quantity and the engine fuel injection quantity; if the engine is in the regeneration mode, determining whether the engine oil amount is greater than or equal to a first oil amount threshold, or whether the engine oil amount is less than or equal to a second oil amount threshold; if the engine oil quantity is greater than or equal to a first oil quantity threshold, triggering a timer to start timing when the engine oil quantity is greater than or equal to the first oil quantity threshold so as to obtain a first accumulated time length, determining whether the first accumulated time length is greater than or equal to a first time length threshold, or triggering the timer to start timing when the engine oil quantity is less than or equal to a second oil quantity threshold so as to obtain a second accumulated time length, and determining whether the second accumulated time length is greater than or equal to a second time length threshold; if the first cumulative time length is greater than or equal to the first time length threshold value or the second cumulative time length is greater than or equal to the second time length threshold value, determining whether the oil injection quantity difference between the engine oil injection quantity at the current moment and the engine oil injection quantity at the last moment is greater than or equal to a preset value; and if the oil injection quantity difference value is larger than or equal to a preset value, determining that the oil injection quantity change rate of the engine is enabled.
In the application scenario, if the engine is not in the regeneration mode, or the first cumulative time length of the engine oil quantity greater than or equal to the first oil quantity threshold is greater than or equal to the first time length threshold, or the second cumulative time length of the engine oil quantity less than or equal to the second oil quantity threshold is greater than or equal to the second time length threshold, or the difference between the engine oil injection quantity at the current moment and the engine oil injection quantity at the last moment is less than a preset value, determining that the oil injection quantity change rate of the engine is not enabled.
In combination with the above scenario, the following details of the technical scheme of the method for treating hydrocarbon leakage of an engine according to the present application are provided by several specific embodiments.
The application provides a method for treating engine hydrocarbon leakage. Fig. 2 is a flow chart of a method for treating hydrocarbon leakage of an engine according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
s201: and acquiring the running mode of the engine at the current moment, the engine oil quantity and the engine oil injection quantity.
Specifically, the operating mode of the engine, the engine oil amount, and the engine oil injection amount may be monitored in real time.
Optionally, the running mode of the engine at the current moment can be determined through the corresponding parameters of the engine; the oil quantity of the engine can be determined through an oil level gauge, and can be monitored through an oil quantity monitoring sensor; the engine fuel injection amount may be determined by the intake air amount, the engine speed, and the like.
S202: based on the operating mode, the engine oil amount, and the engine oil injection amount, it is determined whether an oil injection amount change rate of the engine is enabled.
Specifically, the fuel injection amount change rate enable is used to indicate that the fuel injection amount change rate satisfies a condition that can be determined by the operation mode, the engine oil amount, and the engine fuel injection amount.
S203: in response to the fuel injection quantity change rate enabling, the post-fuel injection quantity of the engine is controlled to be reduced so as to reduce hydrocarbon leakage of the engine.
Specifically, when the fuel injection quantity change rate is determined to be enabled, the running mode of the engine, the engine fuel quantity and the engine fuel injection quantity can all be considered to reach expected conditions, so that the reduction of the hydrocarbon leakage of the engine can be realized by controlling the reduction of the rear fuel injection quantity of the engine, and the problem of overhigh fuel consumption of the vehicle caused by overlarge hydrocarbon leakage of the engine is solved.
According to the method for treating the hydrocarbon leakage of the engine, the post-injection quantity of the engine is controlled by monitoring the injection quantity change rate of the engine, namely, whether the injection quantity change rate is enabled or not is determined by monitoring the running mode of the engine at the current moment, the engine oil quantity and the engine injection quantity, if the injection quantity change rate is enabled, the post-injection quantity of the engine can be controlled to be reduced, so that the hydrocarbon leakage of the engine is reduced, and the problem that the fuel consumption of a vehicle is high due to the hydrocarbon leakage of the engine can be solved.
In one embodiment, determining whether a rate of change of an injection amount of an engine is enabled based on an operating mode, an engine oil amount, and an engine injection amount includes: determining that the fuel injection quantity change rate of the engine is enabled in response to the first condition, the second condition and the third condition being satisfied simultaneously; in response to the first condition, the second condition, and the third condition not being met simultaneously, determining that a rate of change of the fuel injection amount of the engine is not enabled; the first condition is that the operation mode is a regeneration mode; the second condition is that a first cumulative time length of the engine oil mass being greater than or equal to a first oil mass threshold is greater than or equal to a first time length threshold, or a second cumulative time length of the engine oil mass being less than or equal to a second oil mass threshold is greater than or equal to a second time length threshold, wherein the first oil mass threshold is greater than the second oil mass threshold; the third condition is that the difference between the engine oil injection quantity of the engine at the current moment and the engine oil injection quantity at the last moment is larger than a preset value.
Specifically, it is found through analysis of a large amount of data that when the engine is in the regeneration mode, the engine tends to cause a large amount of hydrocarbon leakage due to sudden load increase after a period of operation condition greater than or equal to a first oil amount threshold is experienced, or when the engine is in idle stop or long downhill (when the engine oil amount is less than or equal to a second oil amount threshold in the case of idle stop or long downhill) for more than a certain period of time, the hydrocarbon leakage due to sudden load increase is caused, so that it is necessary to judge whether the fuel injection amount change rate is enabled by the first condition, the second condition and the third condition at the same time to determine whether the hydrocarbon leakage occurs in the engine.
In an alternative embodiment, the fuel injection quantity change rate enabling needs to satisfy the first condition, the second condition, and the third condition simultaneously to determine whether the engine is suffering from hydrocarbon leakage. That is, the engine needs to be in the regeneration mode, and the first cumulative time period in which the engine oil amount is greater than or equal to the first oil amount threshold is greater than or equal to the first time period threshold or the second cumulative time period in which the engine oil amount is less than or equal to the second oil amount threshold is greater than or equal to the second time period threshold, and the difference between the engine oil injection amount at the present time and the engine oil injection amount at the last time is greater than a preset value, in which case the change rate of the engine oil injection amount is considered to be enabled, the engine is considered to have hydrocarbon leakage, and therefore, by reducing the post-injection amount of the engine to reduce the hydrocarbon leakage, the problem that the fuel consumption of the vehicle becomes high due to the hydrocarbon leakage of the engine can be solved.
Alternatively, if any one of the first condition, the second condition, and the third condition is not satisfied, it is considered that the rate of change of the fuel injection amount of the engine is not enabled in this case, and therefore, it may be determined that the current hydrocarbon leakage of the engine has little influence on the fuel consumption of the vehicle, so that in this case, the post-fuel injection amount of the engine may not be reduced.
In one embodiment, further comprising: when the oil quantity of the engine is larger than or equal to a first oil quantity threshold value, triggering a timer to start timing so as to obtain a first accumulated duration; or when the engine oil quantity is smaller than or equal to the second oil quantity threshold value, triggering a timer to start timing so as to obtain a second accumulated duration.
Specifically, when determining the engine oil amount, it may be determined first whether the engine oil amount at the present time is greater than or equal to the first oil amount threshold, or whether the engine oil amount at the present time is less than or equal to the second oil amount threshold. If the engine oil quantity at the current moment is greater than or equal to a first oil quantity threshold value, triggering a timer to start timing from the current moment to obtain a first accumulated duration; or if the engine oil quantity at the current moment is smaller than or equal to the second oil quantity threshold, triggering a timer to start timing from the current moment, and obtaining a second accumulated duration.
Optionally, the end time of the first cumulative length may be the time when the first time threshold is reached, and the end time of the second cumulative length may be the time when the second time threshold is reached.
Optionally, by determining the first accumulation duration or the second accumulation duration, the enabling judgment of the fuel injection quantity change rate of the subsequent engine can be realized, so that when the fuel injection quantity change rate is enabled, the fuel leakage is reduced by reducing the rear fuel injection quantity of the engine, and the problem that the fuel consumption of the vehicle is high due to the fuel leakage of the engine can be solved.
In one embodiment, further comprising: when the engine oil amount is less than the first oil amount threshold and greater than the second oil amount threshold, a timer is triggered to freeze.
Specifically, once the oil quantity of the engine is monitored to be smaller than the first oil quantity threshold and larger than the second oil quantity threshold, the timer is immediately triggered to freeze, so that accuracy of the first accumulated time length and the second accumulated time length is improved, enabling judgment of the oil injection quantity change rate of the subsequent engine is achieved, and when the oil injection quantity change rate is enabled, hydrocarbon leakage is reduced by reducing the post-oil injection quantity of the engine, and therefore the problem that the oil consumption of the vehicle is high due to the hydrocarbon leakage of the engine can be solved.
In an alternative embodiment, the engine oil amount being less than the first oil amount threshold and greater than the second oil amount threshold may include the following two cases:
one is that when the engine oil quantity is monitored to be smaller than the first oil quantity threshold and larger than the second oil quantity threshold at the current moment, the hydrocarbon leakage of the engine at the current moment is considered to have no influence on the vehicle oil consumption, so that the timer can be triggered to freeze, the engine oil quantity is continuously monitored until the engine oil quantity is larger than or equal to the first oil quantity threshold or the engine oil quantity is smaller than or equal to the second oil quantity threshold, and the timer is triggered to start timing.
In another case, at the current moment, the engine oil quantity is greater than or equal to the first oil quantity threshold, at a subsequent moment, the engine oil quantity is smaller than the first oil quantity threshold and greater than the second oil quantity threshold, and the duration from the current moment to the subsequent moment is smaller than the first accumulated duration, so that the hydrocarbon leakage of the engine is considered to have no influence on the vehicle oil consumption in the duration. Or, at the current moment, the engine oil quantity is smaller than or equal to the second oil quantity threshold, at a subsequent moment, the engine oil quantity is smaller than the first oil quantity threshold and larger than the second oil quantity threshold, and the duration from the current moment to the subsequent moment is smaller than the second accumulated duration, so that the hydrocarbon leakage of the engine is considered to have no influence on the vehicle oil consumption in the duration. The monitoring of the engine oil may continue until the engine oil is greater than or equal to the first oil threshold or the engine oil is less than or equal to the second oil threshold, triggering a timer to restart timing.
In one embodiment, further comprising: when the first cumulative length is greater than or equal to the first time length threshold, or when the second cumulative length is greater than or equal to the second time length threshold, the timer is triggered to zero.
Specifically, the first cumulative time length is greater than or equal to the first time length threshold value, or the second cumulative time length is greater than or equal to the second time length threshold value, the hydrocarbon leakage of the engine is considered to have an influence on the fuel consumption of the vehicle, so that the subsequent engine fuel amount does not need to be continuously monitored, zero clearing of the timer can be triggered, influence on the cumulative time length when the engine fuel amount is monitored next time is avoided, and therefore the accuracy of the cumulative time length when the engine fuel amount is monitored next time can be improved.
In an alternative embodiment, corresponding electronic control data, such as a set oil quantity threshold, a set duration threshold, a set difference threshold, etc., may be modified according to actual vehicle performance, so as to meet actual requirements of vehicles of different models, due to different performances of different models of vehicles.
According to the method for treating the hydrocarbon leakage of the engine, three judging conditions are determined through the regeneration mode of the engine, the oil quantity of the engine and the oil injection quantity of the engine, and when the oil injection quantity change rate of the engine meets the three judging conditions simultaneously, the oil injection quantity change rate of the engine is considered to be enabled, namely the engine is enabled to generate excessive hydrocarbon leakage, so that the aim of reducing the hydrocarbon leakage of the engine can be fulfilled by controlling the reduction of the rear oil injection quantity of the engine, and the problem that the oil consumption of a vehicle is increased due to the hydrocarbon leakage caused by sudden load increase of the engine is solved.
