Abstract

The invention provides a method and a device for detecting carbon deposit of an air injection valve and electronic equipment. According to the method, if the running state of an engine meets the preset running state requirements, the gas rail pressure value and the air inlet manifold pressure value of an engine are collected, and when the difference value between the gas rail pressure value and the gas inlet manifold pressure value is larger than a preset pressure difference threshold value, the carbon deposit blockage of the gas injection valve is determined, and the carbon deposit warning information is output. According to the method, it is informed that the carbon deposit is too much when the carbon deposit amount is large, so that the user can know the carbon deposit condition in time.

Description

technical field [0001] The invention relates to the field of gas engines, and more specifically, to a method, device and electronic equipment for detecting carbon deposits in jet valves. Background technique [0002] The gas engine injection valve refers to the device that the gas engine injects gas into the air and gas mixer, and enters the cylinder through the intake manifold. Carbon deposits will occur in gas engine injection valves as the working cycle increases. Among them, carbon deposition refers to the occurrence of carbon, sulfur and other substances on the injection valve after the engine has been used for a period of time. After the occurrence of carbon deposition, it will lead to the loss of gas flow, which will seriously affect the power and emission of the vehicle. [0003] In the prior art, the driver decides whether there is carbon deposition based on subjective assumptions, and then decides whether to clean the injection valve, but does not know the actual...
