Embodiment Construction
[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] In the prior art, electrical components such as sensors and actuators are detected during the running of the engine, and if the electrical components fail, a fault code is generated and a fault warning is issued. When a DTC is received, it can be determined that the engine has malfunctioned. And by comparing the fault code with the fa...

The invention provides a method and device for determining an engine fault. The method comprises the following steps of: obtaining engine operating parameters; inputting the engine operating parameters into a pre-established neural network model; processing the engine operating parameters based on the neural network model to obtain an output result corresponding to a fault result; and determiningwhether the engine fails according to the output result of the neural network model. The operating parameters comprise at least the gas path parameters and the oil path parameters of the engine duringoperation. The neural network model uses the gas path parameters and oil path parameters of the engine during operating as the training samples, and uses the fault result corresponding to the gas path parameters and the oil path parameters as the sample tags to train. According to the method and device for determining the engine fault, it can be determined whether the engine has faults such as gas path faults, oil circuit faults, and the like by processing the engine operating parameters without generating a fault code.
Description
technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a method and a device for determining engine faults. Background technique [0002] If a fault occurs during engine operation, a fault code will be generated, and the fault code of the engine can be determined according to the fault code. For example, if the fault code is P0076, the high end of injector 1 is short-circuited to the power supply; if the fault code is P007D, the high end of injector 2 is short-circuited to the power supply; if the fault code is P0083, the high end of injector 3 is short-circuited to the power supply. [0003] However, when a fault related to engine performance occurs, no fault code will be generated. For example, when an air circuit fault or an oil circuit fault occurs, the corresponding fault code will not be generated, and it will not be possible to determine whether a fault code has occurred Malfunctions related to engine performance....
