Comparative Study on Fuel Consumption and Different Driving Cycles for a Passenger Car in Malaysia via 1-D Simulation

The purpose of this study is to analyze the fuel consumption of passenger cars in Malaysia by using 1D-simulation. The analysis of fuel consumption will focus on common model of cars in Malaysia and will be carried out by using existing driving cycle. New European Driving Cycle (NEDC), Federal Test Procedure (FTP75) Driving Cycle, and Worldwide Harmonized Light Vehicle Test Procedure (WLTC) Driving Cycle were used as the established driving profiles. The new local driving cycle which was developed by UniMAP Motorsport Technology Research Unit (MoTECH) was used as the main driving profile for the simulation. A 1.3L Perodua Myvi 2012 with manual transmission was been selected as the vehicle model for the project. The simulation results were compared with the established driving cycles. The results show the average fuel consumption and emissions of passenger cars is critically affected by the driving behaviors' and vehicle engines condition. The aggressive driving gives the higher rate of fuel consumption and also the cold start-up engine affecting the fuel devours and emissions rate. In addition, comparison of the obtained simulation results with manufacturer's published data showed a good agreement thus indicating suitability of the model to be used in further research.
