In this article effect of ambient condition including temperature, pressure and humidity and also variation
of fuel composition on engine specific fuel consumption and fuel consumption of vehicle and also nitrogen
oxides has been investigated. Simulation has been done by engine cycle simulator GT-Power. Selected
working points for simulation in this research are all in part load and in driving cycle are repeated high and
consumption fuel is CNG. Selected engine for simulation is EF7.1.7NA. Base simulation model, validated by
experimental part load data with sufficient precision. Also for investigating effect of ambient pressure variation,
a test has been done on engine that results shows acceptable adjusting with simulation. Also vehicle fuel
consumption and NOx emission standard is compared with results of simulation.
