摘要： A fuel supply system for an internal combustion engine includes a heat exchanger (20) that has a heat exchanging wall between a liquefied fuel passage (20a) and an engine coolant passage (20b). Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.

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.

摘要： Upon a start of the internal combustion engine (10) , a starting system causes an injector (41) to inject fuel into and causes an ignition plug (45) to ignite a mixture in a cylinder stopped in the expansion stroke, and causes the injector (41) to inject fuel into and causes the ignition plug (45) to ignite a mixture at or in the vicinity of the compression TDC in a compression-stroke cylinder that follows the expansion-stroke cylinder. When the engine coolant temperature is equal to or higher than a predetermined temperature, and when the cylinder stopped in the compression stroke is stopped in the first half of the compression stroke, the starting system retards the fuel injection timing for the compression-stroke cylinder.

摘要： A low-pressure fuel supply system (11) for applying pressure to a fuel by using a feed pump (14) and supplying the fuel to a manifold fuel injection mechanism (12), and a high-pressure fuel supply system (21) branched from the low-pressure fuel supply system (11) and for applying pressure to the low-pressure fuel by using a high-pressure pump (23) 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 (22) are provided. The high-pressure pump (23) supplies all the pressurized fuel to the high-pressure fuel supply system (21), irrespective of an actuation state of the in-cylinder fuel injection mechanism (22). Excessive fuel is returned when a relief valve (29) is opened. Thus, pulsation caused by operation of the high-pressure pump is reduced, and the fuel can be supplied in a proper quantity.
