The objective of this paper is to presents the gas flow pressure profile in the intake port of port injection compressed natural gas (CNG) engine spark ignition using GT-Power software for steady-state and transient simulation. The port injection CNG engine spark ignition computational model is developed from the real diesel engine data, where these data input to software window libraries. In this research, the simulation of engine computational model is running in variations engine speeds from 500, 1000, 1500, 2000, 2500, 3000, 3500 and 4000 rpm. The simulation output data is collected from the GT-Post post processing plots for static pressure versus crank angle and GT-Post post processing casesRLT for pressure in variations engine speeds. The simulation results are shown the characters in intake port pressure profile of port injection CNG engine in variations engine speeds. The detail of intake port gas flow pressure profile performance of port injection CNG engine is shown in graphs in this paper.
