    摘要: An internal combustion engine is provided in which fuel pressure is changed and fuel injection is controlled in accordance with engine operating conditions. The internal combustion engine comprises a cylinder, a direct injection injector, a detection unit, and a control unit. The control unit includes two maps describing two factors of a fuel injection characteristic coefficient and an invalid injection period with respect to the fuel pressure of the direct injection injector. A first calculating section calculates a required fuel injection quantity. A second calculating section calculates a required fuel injection period in accordance with the required fuel injection quantity and the two factors of the fuel injection characteristic coefficient and the invalid injection period with respect to the fuel pressure. A controlling section controls the fuel injection such that the fuel is injected for the required fuel injection period.

    摘要: If the surface of metallic mold should not be highly transcribed to the surface of product in injection molding the plastic products, the transcription defects such as weld, shrinkage, etc. are caused to the surface of product. Further, if the resin should be exposed to the surface of high temperature metallic mold more than necessary during the molding, the filler and the like of glass and so forth are contained into the resin, and in this case, they are left over on the surface of metallic mold, resulting in the transcription defect. These problems can be solved by heating the surface temperature of metallic mold higher than the glass transfer temperature of resin if the resin is non-crystal and higher than the fusion point temperature if the resin crystal, with the temperature raising speed of more than 2° C. every second, maintaining this temperature during the resin charging, and by cooling at the lowering speed of more than 2° C. every second after the completion of charging. This temperature control shall be conducted with the feed back control while detecting the surface temperature of metallic mold by the temperature detection sensor mounted at the position close to the surface of metallic mold.

    摘要: There is provided an internal combustion engine, in which a fuel pressure is changed and a fuel injection quantity is controlled in accordance with an engine operating condition when fuel is injected. The internal combustion engine comprises a cylinder, a direct injection injector arranged so as to supply the fuel to the cylinder, a detection unit for detecting an operating condition of the internal combustion engine, and a control unit for controlling the fuel injection. The control unit includes two maps describing tow factors of a fuel injection characteristic coefficient and an invalid injection period with respect to the fuel pressure of the direct injection injector, a first calculating section for calculating a required fuel injection quantity necessary for injecting the fuel into the cylinder in accordance with an information from the detection unit, and a second calculating section for calculating a required fuel injection period in accordance with the required fuel injection quantity and the two factors of the fuel injection characteristic coefficient and the invalid injection period with respect to the fuel pressure both of which are obtained from the two maps, a controlling section for controlling the fuel injection such that the fuel is injected for the required fuel injection period (T) through the direct injection injector.

    摘要: Two embodiments of water cooled internal combustion engines employing an EGR system. The embodiments also utilize direct cylinder injection. The EGR system is formed integrally within a housing assembly that also forms a portion of the cooling system for the engine and particularly a return coolant manifold. In this way, the exhaust gas recirculation valve can be cooled and its life and performance improved. In addition, this reduces the amount of heat added to the intake system and thus improves the volumetric efficiency of the engine.
