摘要： A fuel injection device is equipped with a fuel injection valve that is mounted in an engine body and injects fuel containing air bubbles, and void fraction adjustment means that changes a void fraction of the fuel that is to be injected from the fuel injection valve. The void ratio adjustment means increases the fuel pressure of the fuel to be injected from the fuel injection valve when an increase of the void fraction is requested. The void fraction adjustment means adjusts the void fraction of the fuel by changing temperature of the fuel to be injected from the fuel injection valve. By appropriately controlling the void fraction, both fuel atomization and securement of the net amount of fuel can be achieved.

摘要： In a fuel injection nozzle for an internal combustion engine, a first cavity is disposed downstream of a valve seat in a direction in which fuel flows. A second cavity is disposed downstream of the first cavity in the direction in which the fuel flows. A fuel passage connects the first cavity to the second cavity. Fuel injection holes (24) lead to the second cavity. With this configuration, when the fuel flows through the first fuel passage, cavitation is induced. Cavitation bubbles flow into the second cavity along with the fuel. When the fuel is retained in the second cavity, 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.

摘要： The base end portion of an injector is connected to a delivery pipe. A fuel passage, through which the fuel in the delivery pipe flows close by an injection port formed in the front end portion of a valve body and is then returned to the delivery pipe, is formed in the injector. Even if communication between the fuel passage and the injection port is blocked by a needle valve, the fuel constantly flows close to the injection port while circulating in the fuel injection system, Also, part of the fuel flowing through the fuel passage is injected from the injection port to a combustion chamber by permitting the communication between the fuel passage and the injection port.
