A Diesel Engine Exhaust Temperature Abnormal Causes Analysis And Solution Measures Research
Engine exhaust temperature is an important parameter to measure whether the engine is running normally,so how to be able to quickly determine the real cause of abnormal exhaust temperature and solve it is a problem that needs to be solved urgently.This paper analyzes and solves the cause of abnormal exhaust tempera-ture of a diesel engine through fault tree analysis method,starting from fuel supply system,cooling water sys-tem,turbocharger and external environmental factors,and finally confirms that the abnormal exhaust tempera-ture is caused by the test environment resulting in less air intake to make fuel combustion inadequate causing af-terburning,and finally successfully eliminates the fault of high exhaust temperature by increasing the mixing tank and increasing the air intake of diesel engine,and Through this problem analysis and summary,it provides a perfect systematic troubleshooting process to solve the problem of high diesel engine exhaust temperature sub-sequently.
