Pressurized fuel injection system has fuel temperature detector for measuring temperature of fuel heated when passing from counter-pressure control chamber to fuel system low pressure side

摘要

The system has a pressure tank, a fuel pump, an injector, a counter-pressure control chamber and an electromagnetic valve for moving the nozzle needle (13) to open and close the valve and a fuel temperature detector for measuring the temperature of fuel heated when emanating from the counter-pressure control chamber (19) to the low pressure side of the fuel system.
