Abstract: An LPG supply system control method of a liquefied petroleum injection engine is provided to prevent generation of an error code of a fuel pump regardless of the actual state of the fuel pump. An LPG supply system control method of a liquefied petroleum injection engine includes the steps of: identifying an initial starting state after detecting a battery off; preventing a fuel pump from being analyzed before a start recognition, if the initial start is identified at the above step after detecting the battery off; and analyzing the fuel pump by comparing a command value of IFB ECU to control the fuel pump with a practical operation value of the fuel pump if not the initial start.

Abstract: PURPOSE: A pressure reducer of an LPG(Liquefied Petroleum Gas) vehicle is provided to improve the commercial value and safety of a vehicle by surely cutting off the supply of fuel when an engine is restarted and by avoiding the delay of hot or cold starting. CONSTITUTION: A pressure reducer(100) of an LPG vehicle is divided into a first pressure reducing chamber and a second pressure reducing chamber(120). The first pressure reducing chamber includes a first valve, a first valve lever, a first diaphragm and a first diaphragm spring. The second pressure reducing chamber includes a second valve(122), a second valve lever(124), a second diaphragm(126) and a second diaphragm spring(128).
