Abstract

A 4-cylinder turbocharged direct-injection diesel engine with optimized advance injection angle and EGR opening has been adopted for test and research which have been carried out in combination with diesel oxidation catalyst (DOC) and particulate oxidation catalytic converter (POC) on professional test bench to verify the effects of DOC and POC technology on diesel engine emissions. Also their rules of influence on the engine have been summarized. Test results indicate that optimized advance injection angle and EGR opening together with correct DOC and POC arrangement can absolutely enable the emissions exhausted by diesel engine to fulfill requirements of Euro IV emission standard.
