Activating full load enrichment in electronic fuel injection IC engine - producing full load enrichment if throttle valve opening angle is greater than specified angle dependent on IC engine RPM

摘要

With the operation of the IC engine, the rpm and the throttle valve opening angle are monitored repeatedly. The specified opening angle associated with the monitored rpm is read from tables and compared to the monitored throttle valve opening angle. With a larger throttle valve opening angle that the specified opening angle a full load enrichment results, with a smaller opening angle than the specified throttle valve opening, a control or regulation of the fuel injection amount is carried out without full load enrichment. A throttle valve position sensor (15) and a rpm sensor (18) are provided, the outputs of which are connected to a control unit (30) contg. a microcomputer (31). An EPROM storage (36) assigned to the comptuer stores the specified throttle valve opening angle as a function of the rpm also a programme for carrying out the method. ADVANTAGE - Full load enrichment is matched to respective operating condition.
