Experimental and Computational of Engine Cylinder Pressure Investigation on the Port Injection Dedicated CNG Engine Development

This study has been investigated the effect of diesel engine convert to sequential port injection dedicated CNG engine on the engine cylinder pressure performance. This research has using GT-Power computational engine model for steady-state and transient simulation and experimental investigation. The investigation and simulation of the engine cylinder pressure performance characteristic profile based on variation engine speed. The engine computational model and experimental has developed based from the diesel engine converted to port injection dedicated Compressed Natural Gas (CNG) engine spark ignition. The simulation and experimental results of cylinder pressure characteristics are shown the cylinder pressure profile and maximum cylinder pressure characteristics. The results shown that the conversion development has decreasing the engine cylinder pressure.
