Fuel injector and fuel injection system |
摘要 |
A fuel supply system has a pump, a common rail, and injectors. Pressurized fuel is stored in the common rail. The common rail distributes the fuel to the injectors. A liquid fuel and a liquefied gas fuel such as dimethyl ether and a liquefied petroleum gas may be used as a fuel. In each injector, a valve element is actuated directly by an electromagnetic actuator. The injector has a low pressure chamber for decreasing a biasing force which acts on the valve element in a valve closing direction. The valve element can be divided for replacement. The injector has means for suppressing the bounce of the valve element. A hydraulic unit which utilizes the fuel suppresses the bounce of the valve element. The fuel supply system is connected to a refrigerating cycle. The fuel leaking from the fuel supply system is cooled and again liquefied by the refrigerating cycle.
