Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for processing an engine fault according to an embodiment of the present disclosure. In the embodiment of the application, the main execution body of the engine fault processing method is a control device. The control device may be an engine controller, among others.
As shown in fig. 1, a method for processing an engine fault according to an embodiment of the present application may include steps S101 to S103, which are described in detail as follows:
in S101, the control apparatus acquires an input parameter of an engine when a failure of the engine is detected.
In practical applications, when the control device encounters a condition where the mixture is insufficiently combusted or is not combusted in one or more cylinders of the engine (i.e., the engine is out of cylinders), indicating an engine transmission fault (i.e., a misfire), the control device may obtain input parameters of the engine.
In the embodiment of the present application, since the engine includes, but is not limited to, an ignition system, an oil supply system, and an air path system, the output parameters of the engine may include, but are not limited to, a fire path parameter corresponding to the ignition system, an oil path parameter corresponding to the oil supply system, and an air path parameter corresponding to the air path system.
The ignition system includes, but is not limited to, an ignition switch, an ignition coil, etc., and is used for igniting the compressed combustible mixture in the combustion chamber at a predetermined time according to the operation requirement of the engine, so that the engine operates normally.
Oil supply systems, also referred to as fuel supply systems, including but not limited to injectors, are used to provide clean fuel to the engine in a timely manner.
The gas circuit system, also called a Valve train, includes, but is not limited to, valves, variable Valve Timing (VVT) devices, canister valves, etc. for injecting combustible mixture or air into the cylinder as required by the engine operation and discharging exhaust gas generated by the combustion in the cylinder.
The VVT device adjusts the phase position or the valve stroke of an engine cam through a control and execution system, thereby achieving the purpose of optimizing the valve distribution process of the engine.
In an implementation manner of the embodiment of the application, the control device may obtain the input parameters of the engine in real time through a server connected with the control device in a wireless communication manner. The server may be a desktop computer or a computer.
In S102, the control apparatus determines a fault category of the engine based on the input parameter.
It should be noted that different input parameters may correspond to different fault categories. The failure categories include, but are not limited to: gas circuit faults, fire circuit faults and oil circuit faults. The gas circuit fault refers to the occurrence of abnormity of gas circuit parameters of the engine (the gas circuit fault judgment condition is met), the fire circuit fault refers to the occurrence of abnormity of fire circuit parameters of the engine (the fire circuit fault judgment condition is met), and the oil circuit fault refers to the occurrence of abnormity of oil circuit parameters of the engine (the oil circuit fault judgment condition is met). Therefore, when the gas path parameters in the input parameters are abnormal, the fault type of the engine can be determined to be a gas path fault, when the fire path parameters in the input parameters are abnormal, the fault type of the engine can be determined to be a fire path fault, and when the oil path parameters in the input parameters are abnormal, the fault type of the engine can be determined to be an oil path fault. The control device may store the correspondence between the different input parameters and the different fault categories in an associated manner.
Based on this, in an embodiment of the present application, the control device may specifically determine the fault category through S201 to S203 shown in fig. 2, which are detailed as follows:
in S201, if the gas path parameter meets a set gas path fault determination condition, it is determined that the fault type of the engine is a gas path fault.
In practical applications, the gas path parameters include, but are not limited to: actual position of the variable valve timing device, canister load, and amount of blow-by. The carbon canister is a canister filled with activated carbon, and is also called a fuel evaporative emission control device. The air leakage amount is used to describe the difference between the set intake air amount and the intake air amount of the final combustion.
Depending on the gas path parameters, the gas path faults include, but are not limited to: the variable valve timing apparatus control abnormality, the canister control abnormality, and the air leakage abnormality.
In this embodiment, the gas circuit fault determination condition may be set according to actual needs, and is not limited herein.
In an embodiment of the present application, the gas path fault determination condition may be: the gas path parameter is greater than the corresponding parameter threshold value. The parameter threshold corresponding to the gas circuit parameter may be set according to actual needs, and is not limited here. It should be noted that, different gas path parameters have different corresponding parameter thresholds.
In the present embodiment, the control apparatus may calculate the difference between the actual position of the variable valve timing device and the set position of the variable valve timing device after obtaining the actual position of the variable valve timing device, and compare the difference between the actual position and the set position of the variable valve timing device with the first threshold value. The set position and the first threshold may be set according to actual needs, and are not limited herein.
The control apparatus may execute step S301 shown in fig. 3 upon detecting that the difference between the actual position and the set position of the variable valve timing device is larger than the first threshold value.
In this embodiment, after obtaining the canister load, the control device may compare the canister load with the second threshold. The second threshold may be set according to actual needs, and is not limited herein.

In this embodiment, after obtaining the air leakage amount, the control device may compare the air leakage amount with a third threshold. The third threshold may be set according to actual needs, and is not limited here.
The control apparatus may perform step S303 shown in fig. 3 when detecting that the amount of air leakage is greater than the third threshold value.
Based on this, in one embodiment of the present application, the control device may specifically determine the fault category of the engine through S301 to S303 as shown in fig. 3, which is detailed as follows:
in S301, if the difference between the actual position and the set position of the variable valve timing device is greater than a first threshold value, the type of the failure of the engine is determined as the control abnormality of the variable valve timing device.
In S302, if the canister load is greater than a second threshold, it is determined that the fault type of the engine is the canister control abnormality.
In S303, if the air leakage is greater than a third threshold, it is determined that the fault type of the engine is the air leakage abnormality.
In the present embodiment, the control apparatus indicates that a large deviation occurs in the actual position of the variable valve timing device when detecting that the difference between the actual position and the set position of the variable valve timing device is larger than the first threshold value, that is, that the variable valve timing device control is abnormal, and therefore, the control apparatus can determine the type of the failure of the engine as the variable valve timing device control abnormality.
When the control device detects that the load of the carbon tank is greater than the second threshold value, the carbon tank load of the engine exceeds the standard, namely the carbon tank control is abnormal, and therefore the control device can determine the fault type of the engine to be the carbon tank control abnormality.
The control apparatus indicates that the difference between the intake air amount set by the engine and the intake air amount finally burned is excessively large, i.e., that the air leakage of the engine is abnormal, when it is detected that the air leakage is larger than the third threshold value, and therefore, the control apparatus may determine that the failure category of the engine is the air leakage abnormality.
In S202, if the fire path parameter meets a set fire path fault determination condition, it is determined that the fault category of the engine is a fire path fault.
In practical applications, the fire parameters include, but are not limited to: ignition angle, ignition energy and actual voltage value of ignition coil.
Depending on the fire path parameters, fire path faults include, but are not limited to: ignition angle abnormality, ignition energy abnormality, and ignition coil abnormality. The ignition angle is also referred to as ignition angle.

The parameter threshold corresponding to the fire path parameter may be set according to actual needs, and is not limited here. It should be noted that, different fire path parameters have different corresponding parameter thresholds.
In the present embodiment, the control device may compare the ignition angle with the fourth threshold value after obtaining the ignition angle. The fourth threshold may be set according to actual needs, and is not limited here.
The control apparatus may execute step S401 shown in fig. 4 when detecting that the ignition angle is smaller than the fourth threshold value.
In this embodiment, the control device may compare the ignition energy with a fifth threshold value after obtaining the ignition energy. The fifth threshold may be set according to actual needs, and is not limited herein.
The control apparatus may perform step S402 shown in fig. 4 when detecting that the ignition energy is less than the fifth threshold value.
In this embodiment, the control device may calculate a difference between the actual voltage value of the ignition coil and the set first voltage value after obtaining the actual voltage value of the ignition coil, and compare the difference between the actual voltage value of the ignition coil and the set first voltage value with the sixth threshold value. The set first voltage value and the set sixth threshold may be set according to actual needs, and are not limited herein.
The control device may perform step S403 as shown in fig. 4 when detecting that the difference between the actual voltage value of the ignition coil and the set first voltage value is greater than the sixth threshold value.
Based on this, in one embodiment of the present application, the control device may specifically determine the fault category of the engine through S401 to S403 as shown in fig. 4, which are detailed as follows:
in S401, if the ignition angle is smaller than a fourth threshold, it is determined that the type of the engine failure is the ignition angle abnormality.
In S402, if the ignition energy is smaller than a fifth threshold, it is determined that the fault type of the engine is the ignition energy abnormality.
In S403, if the difference between the actual voltage value of the ignition coil and the set first voltage value is greater than a sixth threshold value, it is determined that the engine failure type is the ignition coil abnormality.
In the present embodiment, the control device may specify that the ignition angle is deviated, that is, the ignition angle is abnormal, when detecting that the ignition angle is smaller than the fourth threshold value, and therefore, the control device may determine that the failure category of the engine is the ignition angle abnormality.
The control apparatus, when detecting that the ignition energy is less than the fifth threshold, indicates that the ignition energy of the engine is insufficient (does not meet the standard), i.e., the ignition energy is abnormal, and therefore, the control apparatus may determine that the failure category of the engine is the ignition energy abnormality.
The control device may specify that the ignition coil abnormality of the engine (ignition coil failure) is a failure type of the engine, because the control device indicates that a large deviation of the actual voltage value of the ignition coil occurs when detecting that the difference between the actual voltage value of the ignition coil and the set first voltage value is greater than the sixth threshold value.
In S203, if the oil passage parameter meets the set oil passage failure determination condition, the failure type of the engine is determined to be an oil passage failure.
In practical applications, the oil path parameters include, but are not limited to: rail pressure (i.e. oil rail pressure value), oil injection time, oil injection pulse width and actual voltage value of the oil injector.
Oil circuit faults include, but are not limited to, according to oil circuit parameters: rail pressure is abnormal, oil injection time is abnormal, oil injection pulse width is abnormal, and an oil injector is abnormal.
In this embodiment, the oil passage fault determination condition may be set according to actual needs, and is not limited here.
In one embodiment of the present application, the oil passage failure determination condition may be: the oil circuit parameter is smaller than the corresponding parameter threshold value. The parameter threshold corresponding to the oil circuit parameter can be set according to actual needs, and is not limited here. It should be noted that, for different oil path parameters, the corresponding parameter thresholds are also different.
In this embodiment, the control apparatus may compare the rail pressure of the engine with the seventh threshold value after obtaining the rail pressure. The seventh threshold may be set according to practical requirements, and is not limited herein.
The control apparatus may perform step S501 shown in fig. 5 when detecting that the rail pressure is greater than the seventh threshold value.
In this embodiment, the control device may compare the injection time with the eighth threshold value after obtaining the injection time. The eighth threshold may be set according to actual needs, and is not limited herein.
The control apparatus may perform step S502 shown in fig. 5 when detecting that the fuel injection time is greater than the eighth threshold value.
In this embodiment, after obtaining the injection pulse width, the control device may compare the injection pulse width with a ninth threshold. The ninth threshold value may be set according to actual needs, and is not limited here.
The control apparatus may perform step S503 shown in fig. 5 when detecting that the pulse width of injection is greater than the ninth threshold value.
In this embodiment, after obtaining the actual voltage value of the injector, the control device may calculate a difference between the actual voltage value of the injector and the set second voltage value, and compare the difference between the actual voltage value of the injector and the set second voltage value with the tenth threshold. The set second voltage value and the tenth threshold may be set according to actual needs, and are not limited herein.
The control apparatus may execute step S504 shown in fig. 5 when detecting that the difference between the actual voltage value of the injector and the set second voltage value is larger than the tenth threshold value.
Based on this, in one embodiment of the present application, the control apparatus may specifically determine the fault category of the engine through S501 to S504 as shown in fig. 5, which are detailed as follows:
in S501, if the rail pressure is greater than a seventh threshold, it is determined that the fault type of the engine is the rail pressure abnormality.
In S502, if the injection time is greater than an eighth threshold, it is determined that the fault type of the engine is the injection time abnormality.
In S503, if the injection pulse width is greater than a ninth threshold, it is determined that the fault type of the engine is the injection pulse width abnormality.
In S504, if the difference between the actual voltage value of the injector and the set second voltage value is greater than a tenth threshold, it is determined that the fault type of the engine is the injector abnormality.
In this embodiment, when the control device detects that the rail pressure is greater than the seventh threshold, it is indicated that the rail pressure exceeds the standard, that is, the rail pressure is abnormal, and therefore, the control device may determine that the fault type of the engine is the rail pressure abnormality.
When detecting that the oil injection time is larger than the eighth threshold value, the control device indicates that the oil injection time of the engine is too long and exceeds the set time, namely the oil injection time is abnormal, and therefore the control device can determine that the fault type of the engine is the abnormal oil injection time.
When the control equipment detects that the oil injection pulse width is larger than the ninth threshold value, the oil injection pulse width of the engine is too large and exceeds a set value, namely the oil injection pulse width is abnormal, and therefore the control equipment can determine that the fault type of the engine is the abnormal oil injection pulse width.
When the control device detects that the difference between the actual voltage value of the oil injector and the set second voltage value is larger than the tenth threshold, the fact that the actual voltage value of the oil injector has a large deviation is indicated, namely the oil injector is abnormal (the oil injector has a fault), and therefore the control device can determine that the fault type of the engine is the oil injector abnormality.
In another embodiment of the application, the control device is further provided with a fault prompting device, so that the control device can control the fault prompting device to output prompting information for prompting the fault type after determining the fault type of the engine.
In this embodiment, the fault notification device may be an instrument fault lamp, and each fault category may be configured with an instrument fault lamp corresponding to the fault category. Based on this, the control device may control the meter trouble lamp corresponding to the trouble category to turn on after determining the trouble category of the engine.
In S103, the control device executes a preset processing action corresponding to the failure category.
