摘要： A fuel pump draws pumps fuel from a fuel tank to a pressurizing chamber during a suction stroke, and pressurizes and sends fuel in the pressurizing chamber to a delivery pipe. A electromagnetic valve is actuated by electricity from a battery to electively connects and disconnects the fuel tank with the pressurizing chamber. An ECU determines opening and closing timing of the electromagnetic valve based on the rotation al phase of an engine. When the rotational phase of the engine is not identified, the ECU executes a duty control to cyclically repeat supplying and stopping of current to the electromagnetic valve. The ECU extends a current supplying period in each cycle of the duty control as the voltage of the power supply is lowered. As a result, the electromagnetic valve is reliably closed particularly at each pressurizing stroke, which improves the pressure increasing efficiency of fuel supplied to a fuel injection system.

摘要： The present invention is directed to fuel injection devices for internal combustion engines. An object of the present invention is to provide a fuel injection device for an internal combustion engine capable of identifying a non-contributing fuel quantity when port injection and cylinder injection are simultaneously performed. If an explosion count and a coolant temperature for any cycle can be acquired, they can be applied to a first map and a second map to thereby find non-contributing fuel for 100% port injection and non-contributing fuel for 100% cylinder injection, respectively. Each of these found values of the non-contributing fuel is multiplied by a corresponding injection share ratio during injection of the non-contributing fuel to thereby find non-contributing fuel that takes into account the injection share ratio. Finally, these values are added up to arrive at a non-contributing fuel requirement value.

摘要： A fuel injector for an internal combustion engine includes a fuel injection valve, a heater, and a controller. The fuel injection valve is configured to supply fuel to the internal combustion engine. The heater is configured to heat the fuel in the fuel injection valve. The controller is configured to: control the fuel injection valve to stop supplying the fuel to the internal combustion engine, control the heater to execute or stop heating the fuel in the fuel injection valve, and control the fuel injection valve to prohibit the stop of supplying the fuel during execution of the heating by the heater.

摘要： An EFI-ECU determines an initial value of a correction value ekthwst for correcting an injection correction amount with reference to a non-heating initial value map if a heater is in operation, and determines the initial value of the correction value ekthwst for correcting the injection correction amount with reference to a heating initial value map if the heater is out of operation. It should be noted herein that the initial value of the correction value ekthwst is set lower under the same condition in the heating initial value map than in the non-heating initial value map.

摘要： In a fuel injection valve body for a direct injection type internal combustion engine, an entire nozzle body tip portion is formed in a conical shape protruding from a nozzle body outer peripheral surface covered with a cap. Therefore, neither a corner portion or a recessed portion is formed on a surface of the nozzle body tip portion. This prevents heat generated by combustion from concentrating at a corner portion or a surface area from enlarging by a recessed portion, which in turn prevents heat generated by combustion from increasing the temperature of the nozzle body tip portion. Moreover, since a foremost portion of a spherical shape is formed such that it does not form a corner portion or a recessed portion in a peripheral portion of a conical shape, heat generated by combustion does not increase the temperature of the nozzle body tip portion. The temperature of a nozzle hole can therefore be prevented from increasing and accumulation of deposits can be restricted.
摘要翻译：在直喷式内燃机的燃料喷射阀体中，整体喷嘴体前端部形成为从盖体覆盖的喷嘴体外周面突出的圆锥状。因此，在喷嘴体前端部的表面上也不形成角部或凹部。由此，能够防止燃烧产生的热量集中在角部或表面区域而不会被凹部扩大，从而防止燃烧产生的热量增加喷嘴体顶端部的温度。此外，由于球形的最前部形成为在圆锥形的周边部分中不形成角部或凹部，因此燃烧产生的热量不会增加喷嘴体末端部的温度。因此可以防止喷嘴孔的温度升高，并且可以限制沉积物的积聚。
