ABSTRACT:
A control system for the fuel injection mechanism of an internal combustion engine, especially a Diesel engine. In order to adapt the fuel admitted to the engine to exact requirements, a correction is made on the basis of air mass flow rate and fuel temperature. The air mass flow rate is deduced from signals generated by an air temperature sensor and an air pressure sensor while the fuel temperature is taken by a fuel temperature sensor. The two temperature signals are applied to a bridge circuit which feeds a differential amplifier whose output is mixed with the pressure signal. The composite mixed signal is applied to a servo-mechanism to limit the excursion of the fuel control rack of the fuel injection pump. Status indicators generate feedback signals for comparison with set-point signals to provide closed-loop control.
