摘要：The fuel injection system for the diesel engine monitors the pressure of the fuelin a control chamber. The pressure changes during the engine cycles are monitored andfrom the dynamic properties of the fuel a temperature factor is deduced. no separate
temperature sensor is required. The pressure characteristic of each cycle has twothreshold pressures, either on the rising or falling part of the characteristic. The peakpressure is also monitored. The temperature calculation uses stored temperature levelscorresponding to preset conditions of pressure changes.
