ABSTRACT:
A Diesel engine including a load responsive mechanism providing a load mechanical output dependent on the load on the engine; a source of vacuum pressure; a load pressure converter communicating with said source and coupled to said load responsive mechanism, the load pressure converter providing a load vacuum pressure level dependent on the load mechanical output; a speed responsive mechanism providing a speed mechanical output dependent on the revolution rate of the engine; a speed pressure converter communicating with the load pressure converter and coupled to the speed responsive mechanism, the speed pressure converter providing an output vacuum pressure level dependent on the load vacuum pressure level and the speed mechanical output; and an EGR control valve for regulating the flow of gases between the exhaust and the intake of the engine in response to the output vacuum pressure level.
