主 题：EMV In this SI Effect of a semi electro-mechanical engine valve on performance and emissions in a single cylinder spark ignited engine
摘 要：In this study,an electro-mechanical valve(EMV) system for the intake valve of a four stroke,single cylinder,overhead valve and spark ignition(SI) engine was designed and *** engine with the EMV system and a standard engine were tested to observe the effects of the EMV on engine performance and emissions at different speeds under full *** EMV engine showed improved engine power,engine torque and break specific fuel consumption(BSFC).A 66% decrease in CO emissions was also obtained with the EMV system,but hydrocarbons(HC) and NO x emissions increased by 12% and 13% respectively.
