DUAL FUEL INJECTION SYSTEM USING HYDROGEN GAS

摘要

A dual fuel injection system is disclosed. According to an aspect of the present invention, the dual fuel injection system comprises: an engine unit; an intake port providing combustion air and fuel to the engine unit; an LPG supply unit injecting LPG fuel into the inside of the intake port; a hydrogen supply unit injecting hydrogen gas into the inside of the intake port; and a control unit driving and controlling the LPG supply unit and the hydrogen supply unit. Moreover, the control unit receives a hydrogen injection rate (R) through a program to control a rate of hydrogen injected through the hydrogen supply unit for LPG fuel and hydrogen gas to be mixed and supplied to the engine unit (10).
