摘要： PROBLEM TO BE SOLVED: To prevent breakage of a heat transfer member of a heater caused by overheat of the electric heater, and to improve the combustion when the internal combustion engine is in a cold state by enhancing the evaporation performance by providing the electric heater to promote fuel evaporation of an internal combustion engine. SOLUTION: A fuel supply equipment 5 comprises an auxiliary injection valve 4 for a fuel injection valve on an air-intake passage of an internal combustion engine, an electric heater 30 to heat and evaporate injected fuel from the auxiliary injection valve 4, and a heater relay 16 to control the heat generation of the electric heater. When a state that the heat radiation from a surface of the electric heater is reduced is determined, the heat generation of the electric heater is controlled and reduced by the heater relay during the injection of the fuel injection valve so that the temperature of the heat transfer member 6 of the heater does not exceed the heat-proof temperature thereof. As a result, the surface temperature of the heat transfer member of the heater can be set to be higher than the heat-proof temperature, and the fuel evaporation performance of the electric heater can be enhanced thereby.

摘要： PROBLEM TO BE SOLVED: To improve startability and reduce the exhaust amount of HC at starting by offering such construction that a gasified fuel is supplied to a by-path bypassing a main path. SOLUTION: A main air control valve 16 is provided near an intake port 10 in the main air path 3, and the air control valve is closed at starting. Otherwise, additional injection is performed in an early stage of starting cranking by a port injection valve 5. The main air control valve, when provided, accelerates the gasification of the fuel from an auxiliary injection valve 6 in an early stage of stating cranking, improves startability because of a less fuel intake delay and reduces the exhaust amount of HC at starting. The additional injection, when performed in an early stage of cranking by the port injection valve 5, improves startability because of quicker supply of the fuel to cylinders and reduces the exhaust amount of HC at starting.

摘要： PROBLEM TO BE SOLVED: To increase a fuel vaporizing capacity of a heater heating surface without causing an increase in power consumption of a heater heating part and an increase in device size, in a fuel vaporization accelerator for an internal combustion engine. SOLUTION: The heating surface 76 as a sub passage 75 in the fuel vaporization accelerator 100 has a projection 220 as a restriction. Thus, a fuel liquid film 106 injected to the heating surface 76 resides longer on the heating surface 76. A quantity of heat transmitted from the heating surface 76 to the fuel liquid film 106 is increased. A vaporization quantity of fuel is increased, so that without an increase in heater capacity and heater heating surface area, a small fuel vaporization accelerator is provided. COPYRIGHT: (C)2004,JPO

摘要： Atomizing air flowing in an atomizing gas passage is merged with a fuel spray to promote atomization of the fuel, and carrier air flowing in a carrier gas passage is merged with the fuel spray at a further downstream position so as to surround the fuel spray. By doing so, the atomized fuel spray is carried to the downstream side so as to prevent the fuel spray from adhering onto the wall surface. The starting-up performance, fuel consumption and exhaust gas cleaning of an internal combustion engine are improved in this way.

摘要： A combustion state detection system for an internal combustion engine in which a timing signal associated with the rotation of the crankshaft by a predetermined angle is detected and corrected, and a combustion state parameter is calculated from the timing signal. Further, the deviation of the calculated combustion state parameters for normal combustion is detected between the cylinders, and the correction amount of the timing signal is calculated. A reference cylinder is determined by the means (706, 707) for detecting the deviation. The deviation is detected between the combustion state parameter for normal combustion of the reference cylinder and the cylinder opposed thereto and the combustion state parameter for normal combustion of the remaining cylinders. The correction amount is calculated in such a manner as to control the correction amount to not more than a predetermined value or to zero from the detected deviation.

摘要： A main passage mounting a throttle valve and an air bypass flow passage for reducing HC emission by promoting atomization of the fuel spray injected from the assembly pipe fuel injector are integrated in a body of an intake air control device arranged upstream of an assembly pipe in a one-piece structure to form a unit. Thereby, the intake air control device can be easily manufactured and easily mounted on and dismounted from the intake air system. The amount of HC emitted during warming-up operation of an internal combustion engine is reduced by efficiently supplying fuel spray injected from an assembly pipe fuel injector at the time of starting and warming-up operations for the internal combustion engine.
