Abstract:
The LPG fuel (Liquified Petroleum Gas) is currently an energy source being widely applied in many fields in Vietnam, making a significant contribution to the development of the national economy. The paper presents the research results of applying the LPG fuel for using motorbikes. The traditional liquid fuel system (gasoline) on a motorbike is replaced by an electronically controlled LPG-fuel injection system. LPG fuel is designed to inject into the intake manifold. The injection quantity and injection timing are calculated and controlled by the electronic control unit through the calculation and analysis of the input key parameters such as intake air pressure and temperature, throttle position, engine speed, and camshaft position. The testing results on the real road in an urban area show that the motorbike operates stably on flat and uphill roads. In addition, the cost of the LPG fuel consumption is less than that of the gasoline fuel consumption.
