E113 Research and Development of New LPG Engine with Liquid Fuel Injection System (1^<St> Report) : Overview of Liquid Fuel Injection System and Research and Development of The Fuel Pump and The Control

Abstract

The LPG vehicle spread as an alternative fuel vehicle for a petroleum fuel vehicle all over the world. In recent years, Japan actively promotes the remodeling LPG vehicle. In this study, Nikki develops the new LPG prototype vehicle equipped with Nikki advanced technology of multi-point liquid fuel injection system, and investigates fuel consumption rate and exhaust performance of the LPG vehicle. As the 1st step, this paper describes the outline of the LPG fuel pump and the control method. The typical result indicates that the LPG liquid fuel injection system can reduce an amount of electric power consumption than a conventional gasoline system.
