Fuel injector for internal combustion engine, has sensor with measuring body, which partially encloses moving device, where device exhibits magnetization in enclosing region over body

摘要

The fuel injector (1) has a moving device, which performs opening and closing movement for opening and closing a fuel injection opening (3) to inject fuel into a combustion chamber (4). A measuring device (5) formed as an eddy current sensor records the termination of fuel injection in the chamber. The sensor has a measuring body, which partially encloses the moving device. The device exhibits magnetization in the enclosing region over the body. An independent claim is also included for a method for recording the termination of injection of fuel into a combustion chamber.
