Diesel Engine After-treatment System HC Coverage Fault Analysis
The main characteristics of the vehicle engine faults,which are the subject of research,are ana-lyzed through the distribution of the fault models,application scenarios,and table frame tests.Reverse combing Diesel after-treatment due to hydrocarbon overwriting mechanism,to find an optimization measure for the final engine emissions exceeding the standard due to after-treatment hydrocarbon overwriting.According to the analy-sis,the main causes of hydrocarbon coverage are not sound combustion chamber design,poor atomization of fuel injectors after carbon build-up,low engine design temperature,and poor driving habits.
