Research and Development of a Liquid Fuel Injection LPG Engine System Based on the Gasoline Engine (2nd Report)

- Optimization of an LPG Fuel supply System -

Abstract

In this paper, it is shown that in a LPG liquid-phase injection engine, the pressure in a LPG fuel supply system should be controlled which lead to a fuel efficient engine system. Especially at a high output of injection fuel follow, the pressure is not necessarily controlled at high pressure. Thus the optimal pressure is determined experimentally and the experiments are followed to control the pressure at the lower optimal pressure for different outputs of the injection fuel follows for the different speeds of the engine. The fuel supply system without the return pipe exploited in our laboratory is used.
