毕业设计（论文）外文摘要
Title : Detection and fault diagnosis of diesel engine
Abstract :
Diesel engine as a major power machinery, widely used in various industries, in national economy and daily life play a decisive role in.
Diesel engine set of reciprocating, rotary, shock and other moving parts in one, has a complex structure, poor working conditions, using the load range characteristics. Onthe state of diesel engine for tracking and fault diagnosis can effectively improve the diesel engine running benefits. In order to improve the safety of diesel engine power plant and the reliability of diesel engine, fault detection and diagnosis is very important.
This paper mainly through the four part of the analysis of the diesel engine testing and diagnosis technology, the first step of diesel engine fault diagnosis research status at home and abroad and the development trends. The second part is to find the information by summing up diesel engine detection and diagnosis methods. The third part of the diesel engine fuel supply system of detection and diagnosis, this part mainly through the analysis of the fuel supply system of diesel engine high pressure oil pipe oil pressure waveform characteristics and fuel injection timing detection of fuel supply system in the detection and diagnosis strategy. The fourth part is the brief introduction of electronic control diesel engine fault detection and diagnosis, this part is mainly based on electronic controll
