Range extender engine is one of the main components of the range-extended electric vehicle (REEV) and together with a generator to extend the mileage of the electric vehicle. The main component of REEV is an electric motor, battery, and generator set that consist of generator and engine. In this study, we compared two models of REEV performance with two different types of the engine by simulation. Single cylinder 499 cc gasoline engine and single cylinder 667 cc diesel engine are chosen as the object of this research especially relating to the utilization of the fuel consumption and CO 2 emissions when fitted to an electric vehicle. The simulation was conducted by using AVL Cruise software and performed by entering the data, both experiment and simulation data, on all the main components of REEV. This simulation was performed in Japan 08 driving cycle. Based on the simulation, fuel consumption is reduced up to 35.59% for REEV with single cylinder diesel engine 667 cc compared to REEV with single cylinder gasoline engine 499 cc. The reduction of CO 2 emissions from REEV with single cylinder 499 cc gasoline engine compared to REEV with single cylinder 667 cc diesel engine up to 30.47%.
Based on the analysis and the induction of electronic control fuel injection engine common failure which can't start, and according to the engine’s working principle and failure mechanism, established the electronic control fuel injection engine’s fault tree, and having made qualitative analysis about the working reliability of the engine by using the fault tree analysis method. This paper offered the electronic control fuel injection engine’s failure form which can’t start in classification, discussed the process of establishing the fault tree at length, even built and mapped the engine’s fault tree which can’t start; According to the natural gas compressor’s fault tree diagram, and applying the descending method to get the fault’s minimal cut sets. By making qualitative analysis, finding out the main influence factors of failure, and putting forward quite perfect methods of removing fault, which providing electronic fuel injection engine maintenance with the beneficial reference.
