    摘要: A low-pressure fuel supply system for applying pressure to a fuel by using a feed pump and supplying the fuel to a manifold fuel injection mechanism, and a high-pressure fuel supply system branched from the low-pressure fuel supply system and for applying pressure to the low-pressure fuel by using a high-pressure pump of a metering delivery type driven in accordance with the engine operation state and supplying the resultant fuel to an in-cylinder fuel injection mechanism are provided. The high-pressure pump supplies all the pressurized fuel to the high-pressure fuel supply system, irrespective of an actuation state of the in-cylinder fuel injection mechanism. Excessive fuel is returned when a relief valve is opened. Thus, pulsation caused by operation of the high-pressure pump is reduced, and the fuel can be supplied in a proper quantity.

    摘要: A fuel injection control system for an internal combustion engine in which a driving signal for a high pressure fuel pump is calculated by using proportional plus integral control based on a difference between a delivery pressure of the high pressure fuel pump and a target pressure thereof. A delivery pressure of a low pressure fuel pump is caused to decrease when an amount of change per unit time of an integral term shows a decreasing tendency or zero, whereas the delivery pressure of the low pressure fuel pump is caused to increase when the amount of change per unit time of the integral term shows an increasing tendency. In cases where an increase in the integral term resulting from a change in the target delivery pressure of the high pressure fuel pump has occurred, the increase in the delivery pressure of the low pressure fuel pump is prohibited.

    摘要: In a starting system of an internal combustion engine including a fuel injection valve that directly injects fuel into a corresponding cylinder and a spark plug that ignites an air-fuel mixture in the cylinder, injection of the fuel from the fuel injection valve and ignition performed by the spark plug are stopped when engine stop conditions are met. If the engine restart conditions are met during rotation of the engine after the engine stop conditions are met, the fuel is injected from the fuel injection valve into an expansion-stroke cylinder that is in the expansion stroke at the time when the engine restart conditions are met, and the mixture formed in the expansion-stroke cylinder is ignited by the spark plug.
