The Research of Arrange Project of Exhaust System on 493 Diesel Engine in the Lab

This paper takes the thermodynamic process simulation theory in internal combustion engine as a foundation,and discusses the effect of exhaust pipe diameter and length on 493 diesel engine performance by BOOST software.The arrange project of exhaust system is given according to the above conclusion and the condition of the lab,and the performance difference is given by BOOST software,which provides theory basis for exhaust pipe arrange in internal combustion engine lab.
