摘要： A control apparatus for an internal combustion engine includes a variable valve mechanism that changes the duration of an intake valve, and a controller that controls the variable valve mechanism to change the duration based on the operating state of the internal combustion engine. If a determination that there is a possibility of engine stalling is made when the internal combustion engine idling, the controller controls the variable valve mechanism so that the duration of the intake valve is made shorter than the duration which is achieved when the determination is made, only during the period until several four-stroke cycles of the internal combustion engine have elapsed after the determination is made. Thus, it is possible to appropriately suppress occurrence of engine stalling when the internal combustion engine is running at a low speed.

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。

摘要： An ECU executes a program including injecting fuel only by an intake passage injector when an engine is idling, starting an addition-type PFI timer, resetting the PFI timer when a count of the PFI timer reaches a set value that is set shorter as the fuel is lighter in fuel property, and injecting the fuel only by an in-cylinder injector.

摘要： An in-cylinder injector injects fuel to be sprayed in the form of an inverted letter V sandwiching a spark plug, as seen in a top view, and in a sector as seen in a side view. The sprayed fuel interferes with an intake valve assuming an open position. An engine ECU executes a program including the steps of: determining with reference to a map a timing of injection of the fuel through the in-cylinder injector (S100); determining a period for injection from an amount of fuel injected (S110); determining in accordance with map whether the sprayed fuel interferes with the intake valve (S120); modifying the period for injection to be advanced by a period for injection having the sprayed fuel interfering with the intake valve (S130); and determining a timing of injection and a period for injection (S140).

摘要： An injection controller for an internal combustion engine that suppresses the accumulation of deposits on a nozzle hole of a direct injection valve. The injection controller includes the direct injection valve, which injects fuel into a cylinder, and an intake passage injection valve, which injects fuel into an intake passage. An ECU, which is connected to the direct injection and intake passage injection valves, executes a first fuel injection mode for injecting fuel with the direct injection valve and a second fuel injection mode for injecting fuel with the intake passage injection valve. The ECU switches fuel injection modes from the second fuel injection mode to the first fuel injection mode for a predetermined period when fuel is to be injected in the second fuel injection mode.
