The article describes the Bosch Motronic Electronic engine Control System which operates in conjunction with fuel injection and electronic ignition. The control of injection period can be performed with 1% accuracy compared with the 5% of typical carburettor systems. As an integrated system, the motronic equipment controls, with the aid of a microcomputer, fuel-injection and ignition according to specified programs as a function of operating data such as load, speed and temperature. Input variables are detected by sensors for air flow, engine speed, temperature and other signals. With this system, speed data are taken from the crankshaft so that tolerance with respect to knock limit can be reduced and ignition angle advanced to give improved fuel economy. It is possible to add further functins such as electronic control of automatic transmissions and antiskid braking. (TRRL)
