Abstract: A misfire diagnosis controlling method of a liquefied petroleum injection engine is provided to solve a misfire diagnosis error by preventing misfire diagnosis when a fuel level is lower than a reference level. A misfire diagnosis controlling method of a liquefied petroleum injection engine includes receiving a current fuel pressure and a current fuel temperature from a fuel pressure sensor and a fuel temperature sensor, calculating a saturation vapor pressure from the current fuel pressure and the current fuel temperature and a pressure margin depending on the current fuel pressure and the current fuel temperature, and comparing the current fuel pressure with a sum of the saturation vapor pressure and the pressure margin to determine that the fuel pressure is normal when the current fuel pressure is higher than the sum of the saturation vapor pressure and the pressure margin and determine that the fuel pressure is abnormal when lower than the sum.

Abstract: A fuel quantity correction system of an LPI(Liquefied Petroleum Gas Injection) vehicle and a method thereof are provided to improve fuel efficiency by performing fuel injection which follows a target mixing ratio regardless of vehicle operating condition. A fuel quantity correction system of an LPI vehicle comprises a bombe(100), an injector(300), a temperature sensor(202), a pressure sensor(203), a combustion chamber pressure sensor(501), and a controller(600). The bombe contains fuel in a liquid state, and includes a pump(105) for pressing the fuel. The injector is arranged to inject the determined amount of fuel to a combustion chamber(500). The temperature sensor is mounted at a predetermined position of a fuel supply line(200) for interconnecting the bombe and the injector, and detects the temperature of the fuel supplied to the injector. The pressure sensor is mounted at a predetermined position of the fuel supply line for interconnecting the bombe and the injector, and detects the pressure of the fuel supplied to the injector. The combustion chamber pressure sensor detects the pressure in the combustion chamber. The controller calculates the basic fuel amount on the basis of the temperature and pressure of the fuel supplied to the injector, coolant temperature, and the pressure of the combustion chamber, and determines the final fuel injection amount by applying a density correction factor value in accordance with the temperature and composition ratio of the fuel.
