摘要： An engine is provided comprising an engine housing defining at housing and has a different portion associated with each engine cylinder. Each different portion of the engine auxiliary system has a first electrical actuator coupled to a first valve and a second electrical actuator coupled to a second valve which are wired in series. For example, a fuel injection system is provided with a first electrical actuator operably coupled to a fuel pressurizer and a second electrical actuator operably coupled to a direct control needle valve. The electrical actuators are wired in series on an electrical circuit. A method of controlling a portion of the engine auxiliary system is also provided which consists of actuating a first electrical actuator with a relatively low current and actuating a second electrical actuator with a relatively high current.

摘要： During assembly, shipping and handling before a mechanically-actuated fuel injector is installed into an internal combustion engine, the fuel injector tappet often accidentally disconnects from the fuel injector body. This separation of the tappet from the fuel injector body is caused by a force placed upon the tappet by a biasing means, such as a spring, that pushes the tappet away from the injector body. The fuel injector of the present application solves this problem through the interaction of a retention clip, a retention opening in the fuel injector body, and a retention slot in the fuel injector tappet. The retention clip has a body and a protrusion. The retention clip body is contained within the fuel injector body, and the protrusion extends through the retention opening and into the retention slot. After it is assembled, the fuel injector of the present application remains connected during shipping and handling and permits easy installation into an internal combustion engine.

摘要翻译： 在机械致动的燃料喷射器安装到内燃机中之前的组装，运输和处理期间，燃料喷射器挺杆经常意外地与燃料喷射器主体断开。 挺杆与燃料喷射器主体的这种分离是通过由诸如弹簧的偏置装置施加在挺杆上的力引起的，其将推杆推离喷射器主体。 本申请的燃料喷射器通过保持夹，燃料喷射器主体中的保持开口和燃料喷射器挺杆中的保持狭槽的相互作用来解决这个问题。 保持夹具有主体和突起。 保持夹主体容纳在燃料喷射器主体内，并且突起延伸穿过保持开口并进入保持槽。 在组装之后，本申请的燃料喷射器在运输和处理期间保持连接，并且允许容易地安装到内燃机中。
