ABSTRACT In this work, a new algorithm for evaluating the effects of various factors on the engine power and NOx emissions of a common rail diesel engine is introduced. The impacts of eight factors (speed, torque, IMEP, the highest explosion pressure, air-fuel equivalence ratio, the start of injection, duration of injection, and BSFC) on engine power and NOx emissions are evaluated by fuzzy grey membership grades. The result showed that the affect rank on the engine power is the BSFC, torque, IMEP, speed, duration of injection, the highest explosion pressure, the start of injection and air-fuel equivalence ratio. Moreover, the affect rank on the NOxemissions is the BSFC, speed, IMEP, torque, the highest explosion pressure, duration of injection, the start of injection and air-fuel equivalence. This work is very useful for optimizing the performance and emissions characteristics base on operating parameters of diesel engines. Keywords: Fuzzy grey relational analysis; diesel engine; operating parameters; power; NOx emissions. |
