Diesel engine fuel injection control - using supercharger and electronic control unit receiving speed, air pressure and temp. signals

摘要

The engine has a connection for an exhaust gas supercharger to force air into an inlet line. Air pressure and temp. signals are passed to a control unit which also receives engine speed signals. The control unit regulates the combustion air temp. dependent on the temp. of the charging air and also regulates the fuel supply according to all the input signals to the control unit. The control circuit has a fixed value memory (ROM) into which all these signals are entered. In the charging air supply line is an air cooler and the signals corresponding to charging air pressure and temp. are received upstream of the cooler. ADVANTAGE - Fuel supply is closely controlled to match combustion air conditions.
