Simulation of Fuel Consumption and Exhaust Emissions in Dual Fuel Samand Vehicle and Verification with NEDC Modal Test Results

In this article, the fuel consumption and the exhaust emissions have been simulated in dual fuel (Gasoline and CNG) Samand vehicle by means of backward facing simulation. The engine performance and the catalysisconvertor curves have been achieved and they have been applied for simulation of the fuel consumption and the exhaust emissions when the engine is burning either gasoline or CNG. Finally, the simulation results and chassis dynamometer test results under NEDC driving cycle are compared. This comparison indicates a good match between the simulation and the test results and it shows that this model has sufficient accuracy to use in designing and sizing of hybrid electric vehicles (HEV) that they are based on the national vehicle.
