Fuel injector with a measuring device

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.
