摘要： An internal combustion engine includes an in-cylinder injection valve and an intake port injection valve. An ECU controls the fuel injection valves in a fuel injection mode that corresponds to an operational state of the engine. When deterioration of the combustion state is detected while the engine operational state is in a predetermined operational region where fuel is injected at least from the in-cylinder injection valve, the ECU switches the fuel injection mode such that the ratio of the amount of fuel injected from the in-cylinder injection valve to the entire amount of fuel supplied to the cylinder is decreased. As a result, the engine combustion state is prevented from deteriorating while suppressing noise generated in the fuel pressurizing and supplying system.

摘要： A fuel supplying apparatus of an internal combustion engine includes a first fuel supply system, a second fuel supply system, and a pulsation propagation suppressing unit. The first fuel supply system pressurizes a fuel by a low-pressure pump, and supplies the fuel pressurized by the low-pressure pump to a first fuel injection mechanism. The second fuel supply system is branched from the first fuel supply system, further pressurizes the fuel, pressurized by the low-pressure pump, by a high-pressure pump that is driven according to an operating state of the internal combustion engine, and supplies the fuel pressurized by the high-pressure pump to a second fuel injection mechanism. The pulsation propagation suppressing unit is provided in at least one of the first fuel supply system and the second fuel supply system, and suppresses propagation of a pulsation generated in the high-pressure pump to the first fuel injection mechanism.

摘要： In an internal combustion engine in which a throttle valve is substantially fully opened in most of the operating regions such as an in-cylinder injection type internal combustion engine, a technique is provided capable of effectively processing an evaporative fuel while stabilizing a combustion state of the internal combustion engine even in the case that an amount of evaporative fuel generated in a fuel tank or the like is increased. To achieve this technique, a purge amount of evaporative fuel is increased by increasing a differential pressure between an upstream portion and a downstream portion of a purge passage, and the differential pressure between an upstream portion and a downstream portion of a purge passage, and the differential pressure is adjusted in accordance with the combustion state of the internal combustion engine at that time, thereby making it possible to purge the maximum amount of evaporative fuel within a range in which the combustion state is not unstabilized.
