Title:
FUEL INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/131996
Kind Code:
A1
Abstract:
A fuel injection device is provided with a fuel injection valve which is mounted in an engine body and injects fuel containing air bubbles, and a void fraction adjustment means which changes the void fraction of the fuel to be injected from the fuel injection valve. The void fraction adjustment means increases the fuel pressure of the fuel to be injected from the fuel injection valve when the increase of the void fraction is requested. Further, the void fraction adjustment means adjusts the void fraction of the fuel by changing the temperature of the fuel to be injected from the fuel injection valve. By appropriately controlling the void fraction, both fuel atomization and securement of net fuel quantity can be achieved.
