Abstract

A control system is provided for a supercharged diesel engine to control engine air flow in response to an operator-selected fuel flow and in accordance with a predetermined air-fuel ratio schedule chosen for minimizing undesirable exhaust emissions throughout a broad range of engine operating conditions. The control system includes a force-biased relief valve movable between closed and open positions in response to the pressure of air supplied to the engine, wherein the force-bias acting upon the relief valve is altered in response to the operator-selected fuel flow to the engine.
