Abstract

The invention relates to an engine acting non-uniform compensation method, device and equipment and a storage medium, and the method comprises the steps that instantaneous parameter information of acting of each air cylinder during operation of an engine is collected, and the instantaneous parameter information of acting of each air cylinder comprises the instantaneous rotating speed of each air cylinder; inputting the parameter information of each cylinder into a target diagnosis model, and determining the state of the engine through an output result; and when the state of the engine is non-uniform acting, compensating non-uniform acting of each cylinder of the engine according to the instantaneous rotating speed of each cylinder. According to the engine acting non-uniform compensation method, device and equipment and the storage medium, the instantaneous parameter information during operation of the engine is collected, the operation condition of the engine is judged according to the target diagnosis model, when acting of the engine is non-uniform, acting compensation is conducted on the engine according to the parameter information of all the air cylinders, and the working efficiency of the engine is improved. And the real-time performance of non-uniform compensation of the work of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of engine fault diagnosis and control, in particular to a method, device, equipment and storage medium for compensating for uneven engine work. Background technique [0002] When a multi-cylinder engine performs normal work, there will be uneven work of each cylinder, which is mainly caused by factors such as manufacturing errors in the fuel system, wear or performance degradation of key components, and insufficient fuel injection quantity control. The above phenomenon exists in marine engines equipped with mechanical fuel injection systems and high pressure common rail fuel injection systems. Since the fuel supply process and fuel injection process of marine engines equipped with high pressure common rail systems are independent of each other, fuel injection can be achieved for each cylinder. The precise control of timing and fuel injection quantity makes it possible to adjust the uniformity of work done by...
