DEVICE DECREASING TEMPERATURE DIFFERENCE OF LPG FUEL PROVIDING SYSTEM AND METHOD OF ENGINE

摘要

PURPOSE: A device for decreasing the temperature difference of an LPG fuel supply line and a method thereof are provided to improve engine drive performance and liquefaction performance by the lowering of fuel. CONSTITUTION: A method for decreasing the temperature difference of an LPG fuel supply line comprises following steps. The temperature of fuel is sensed through the temperature sensing unit(S502). If the difference of fuel temperature and standard value exceeds critical value(S504), the lowering of the liquefaction performance of the fuel is determined(S505). Fuel cycle speed is accelerated after an electronic pressure regulator is blocked(S507).
