| Abstract: | For a 6-cylinder turbocharged diesel engine,two structure design schemes of internal EGR were put forward and the simulation model was built with the software.According to the simulation results,the scheme of exhaust valve reopening,which was realized by appending a small cam to exhaust cam,was designed.Through the experiment,the influences of internal EGR on power,economy and emission performance were researched.The results show that the internal EGR can effectively reduce exhaust and PM emission. |
