摘要： In a fuel supply apparatus for an internal combustion engine, fuel is delivered to a high pressure fuel pump (7) driven by an internal combustion engine, using an electrically-operated low pressure fuel pump (6), and the fuel pressurized by the high pressure fuel pump (7) is supplied to the internal combustion engine. The fuel supply apparatus includes a low pressure pump control portion (42) that controls the low pressure fuel pump (6) to avoid a discharge failure in the high pressure fuel pump (7) due to insufficiency of a feed pressure at which the low pressure fuel pump (6) delivers the fuel to the high pressure fuel pump (7). The low pressure pump control portion (42) stops the low pressure fuel pump (6) in a case where the discharge failure in the high pressure fuel pump (7) is avoided even when the feed pressure is equal to a gauge pressure of 0.

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 fuel injection nozzle for an internal combustion engine, a first cavity (32) is disposed downstream of a valve seat (12) in a direction in which fuel flows. A second cavity (36) is disposed downstream of the first cavity (32) in the direction in which the fuel flows. A fuel passage (34) connects the first cavity (32) to the second cavity (36). Fuel injection holes (24) lead to the second cavity (36). With this configuration, when the fuel flows through the first fuel passage (34), cavitation is induced. Cavitation bubbles flow into the second cavity (36) along with the fuel. When the fuel is retained in the second cavity (36), the cavitation bubbles are uniformly mixed into the fuel. The fuel, which has been sufficiently mixed with the cavitation bubbles, is injected from the fuel injection holes (24).
