Fault detection device for fuel feed pump has temperature sensor to record temperature of fuel in fuel feed pump and housing of fuel feed pump whereby device determines fault in fuel feed pump and temperature sensor records the fault

摘要

Fault detection device (4) has temperature sensor (33) for recording temperature of fuel flowing in fuel feed pump (2) and temperature of housing (6) of fuel feed pump. The device determines whether a fault in fuel feed pump has occurred or not on the basis of temperature of fuel and housing. The fault is recorded by means of temperature sensor.
