The engine model is used to simulate the intake gas flow pressure characteristics of diesel engine converted to CNG engine. The computational model considers the steady state and transient simulation processes of the intake port. The engine model size is developed from the real diesel engine data and input to software libraries. The simulation of engine model is running in variations engine speeds from 1000 until 4000 rpm. The simulation results are shown in the graph of this study. Copyright © 2008 Praise Worthy Prize S.r.l. All rights reserved. Keywords: CNG engine;GT-power;intake pressure;one dimensional modelling
