Abstract: 본 발명은 연료 분사량 제어장치에 관한 것으로서, 종래의 연료 분사장치는 냉각수의 온도가 높거나 낮음에 관계없이 항상 일정한 압력으로 연료를 엔진에 분사하므로, 냉각수의 온도가 낮을때에 분사되는 연료가 엔진으로 공급되어 미연소됨으로 인해 많은 양의 유해가스가 발생되고, 또한 엔진의 성능도 저하되는 문제점이 있었다. 따라서, 상기 문제점을 해결하기 위한 본 발명은 압력 발생기와 연료 탱크 사이에 연료 리턴량을 조절하는 리턴량 조절부를 설치하고, 연료 펌프의 회전량을 조절하는 제어부를 설치하여 냉각수 온도에 따라 엔진에 분사되는 연료의 압력을 조절하여 엔진의 연소능력을 향상시킬수 있도록 한 연료 분사량 제어장치이다.

Abstract: An engine stop position control method of a hybrid electric vehicle is provided to regularly control a stop position of a crank shaft by instantaneously stopping an engine through a generator when the crank shaft reaches the stop position. An engine stop position control method of a hybrid electric vehicle includes the steps of: transmitting crank angle information indicating the current position of a cylinder from an ECU(Engine Control Unit) to an HCU(Hybrid Control unit); searching a predetermined crank angle as a stop position of an engine(1) according to the crank angle information in input of an engine off signal; and controlling the stop position of the engine through a generator(5) until engine off so that the cylinder reaches a position corresponding to the predetermined crank angle.

Abstract: An LPI fuel system and a method for controlling the bombe pressure of the LPI fuel system are provided to stably maintain the efficiency of power by preventing lowering of the discharge amount of a fuel pump. An LPI fuel system includes a fuel pump(12), an injector(3), an EMS ECU(9), and an IFB ECU(10). The LPI fuel system includes an internal heating unit(7), at least one saturated vapor pressure regulating heating unit(6), and a heating control unit. The internal heating unit is provided on the inner side of the bombe. The saturated vapor pressure regulating heating unit is provided on one side of the exterior and interior of the bombe. The heating control unit controls the saturated vapor pressure in the bombe by operating the saturated vapor pressure regulating heating unit if a signal between fuel injectors reaches the maximum value. The heating control unit controls the saturated vapor pressure regulating heating unit so that the saturated vapor pressure regulating heating unit is turned off if the saturated vapor pressure in the bombe is deviated from a pressure reduction cavitation generating critical pressure.

Abstract: PURPOSE: A heating time/power measuring device of a vehicle electric heating catalyst and a method thereof are provided to measure heating time and power of the catalyst forcibly heated for purifying hydrocarbon exhaust gas discharged at an initial state of engine start. CONSTITUTION: Before starting an engine, an electric heating catalyst is pre-heated. Then, an ignition is turned on for heating a non-heating catalyst. Herein, the non-heating catalyst, the electric heating catalyst, and heating temperatures are detected. By using the detected temperature, activated state of the non-heating catalyst is decided. In the activated state of the non-heating catalyst, on/off of power for the electric heating catalyst is duty controlled.

Abstract: PURPOSE: An improved exhaust manifold is provided to increase the temperature of flux and a carrier by flowing exhaust gas in the shaft direction of a mixing pipe and to enhance the durability of the carrier by regularly guiding the exhaust gas to the carrier. CONSTITUTION: An exhaust manifold comprises a runner(10) exhausting gas after an explosion process by connecting to each cylinder; and a mixing pipe(11) passing a catalyst by putting exhaust gas together. The runner changes the connecting end to the mixing pipe and changes the section of the mixing pipe. Therefore, exhaust gas flows in the shaft direction of the mixing pipe and regularly contacts with the catalyst. The second and the third runner are integrally formed in the mixing pipe in a bent degree lower than before and the first and the fourth runner are made up with the second and the third runner in the curvature similar to the second and the third runner. Thus, exhaust gas from each runner regularly contacts with the catalyst along the mixing pipe.
