Abstract

The invention particularly relates to an engine combustion nonuniformity detection system and method, and the system comprises a vibration sensor which is disposed on a cylinder body of an engine and is used for detecting a vibration signal of the cylinder body; the pipe clamp sensor is arranged on a high-pressure oil pipe of the engine and used for detecting a high-pressure oil pipe pulse signal of the high-pressure oil pipe; the data acquisition card is electrically connected with the vibration sensor and the pipe clamp sensor respectively; and the controller is electrically connected with the data acquisition card, and judges whether the engine burns unevenly or not according to the vibration signals and the high-pressure oil pipe pulse signals acquired by the data acquisition card. According to the engine combustion non-uniformity detection system provided by the invention, fault detection of combustion non-uniformity of each cylinder of the engine is completed by adopting a signal processing means according to signals detected by the vibration sensor and the pipe clamp sensor.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a detection system and detection method for uneven combustion of an engine. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] The engine is the power component of the whole vehicle system, and the uniform combustion of each cylinder of the engine is the basis for the stable operation of the whole vehicle, especially the fuel in the cylinder is not fully burned due to the influence of abnormal factors such as injector failure and performance calibration during the actual operation of the diesel engine Or non-combustion leads to uneven combustion or misfire failure of the engine, which in turn leads to excessive emission of diesel engines, decline in output torque and output power, deterioration of vibration and noise, abnormal noise and many other problems. [0004] Therefor...
