Performance and Emissions of Motorcycle Engine Fueled with LPG-Ethanol by Port Injection
The present paper investigates the performance and emission of a retrofitted Honda 110cc motorcycle engine fueled with LPG-ethanol by simulation and experiment. The ethanol and the LPG are injected separately through the two different injectors. A microcontroller is set up connecting with the ECM of the engine for flexible adjustment of the LPG/ethanol ratio based on the gasoline injector control signal. The measurements were conducted on a special engine testing instrument with an automatic load controller. The simulation was performed with the help of the Ansys Fluent Software. The results show that the LPG-ethanol dual injection forms a stratified mixture distribution at the end of the compression process. The relatively LPG-rich area is found around the spark plug while the ethanol-rich area is located near the cylinder wall. With 30% ethanol addition to LPG, the indicative engine cycle work increases by 4.5% while the emissions of NOx, CO, and HC decrease respectively by 13, 20, and 17% as compared to LPG fueling mode. When the ethanol content is higher than 30%, a special intake manifold design is needed for supporting the evaporation of the liquid fuel.
