چکیده
To meet consumer and legislation requirements, various technologies have been used worldwide to achieve optimal fuel consumption and to reduce greenhouse gas emissions. One of the proposed technologies is cylinder deactivation using various methods, including, injectors cutting off, closing the intake and exhaust valves and crankshaft decoupling. In this paper, a GT-Power model is created to investigate the engine performance of a 1.7L bi-fuel natural-gas engine. The model is also evaluated to predict performance differences between cylinder deactivation and nominal four-cylinder operation, including torque, power, brake specific fuel consumption and exhaust gas temperature. The results showed that cylinder deactivation (CDA) capable of increasing exhaust gas temperature until 40°C, also brake specific fuel consumption (BSFC) reduced by 21%. Comparisons are made between periods of 1500 to 5500 rpm.
