摘要： Methods, systems, and devices are disclosed for injecting a fuel using Lorentz forces. In one aspect, a method to inject a fuel includes distributing a fuel between electrodes configured at a port of a chamber, generating an ion current of ionized fuel particles by applying an electric field between the electrodes to ionize at least some of the fuel, and producing a Lorentz force to accelerate the ionized fuel particles into the chamber. In some implementations of the method, the accelerated ionized fuel particles into the chamber initiate a combustion process with oxidant compounds present in the chamber. In some implementations, the method further comprises applying an electric potential on an antenna electrode interfaced at the port to induce a corona discharge into the chamber, in which the corona discharge ignites the ionized fuel particles within the chamber.

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： A valve body surrounds a first passage connecting with a cylinder of an engine. A valve member is adapted to be seated on and lifted from the valve seat. An injector body connects with the valve body. The injector body has a pressure control chamber for controlling hydraulic pressure applied to the valve member thereby controlling a lift of the valve member. The injector body has a second passage through which fuel in the pressure control chamber is exhausted. An actuator is adapted to communicating the pressure control chamber with the first passage through the second passage and blocking the pressure control chamber from the first passage. The first passage introduces fuel from the pressure control chamber into the cylinder through the second passage.
