Investigation of CNG engine intake port gas flow temperature based on steady-state and transient simulation

This paper is focused to investigate the gas flow temperature in the intake port of four-stroke port injection CNG engine using GT-Suite software for steady-state and transient simulation. To investigate and simulate the intake port gas flow temperature profile of CNG engine is using GT-Power engine model have been developed in this research. GT-Power is sub-system menu from GT-Suite. The engine model is developed from the diesel engine convert to CNG engine and the engine data input to software library by using CNG as a fuel and spark ignition system. The simulation of engine model is running in variations engine speeds. The simulation output data is collected from the GT-Post results plots and casesRLT in post processing. The simulation results of the intake port engine model are shown the characters in intake port temperature profile in variations engine speeds. The detail performance intake port gas flow temperature is shown in graphs in this paper.
