Fuel injection adaptive electronic control for combustion engine - adjusting quantity between lower and upper threshold values with storage of new value of target quantity

摘要

Signals from an inlet pressure transducer (22), throttle opening sensor (8) and revolution counter (7) to the electronic control unit (2) are processed to produce a command (11) for the pref. electromagnetic injection valve (10) supplying fuel from a tank (16) via a pump (13) and parallel pressure control valve (14). The quantity of fuel is reduced to a value dependent on torque up to a max. which is modified in accordance with actual load and speed. ADVANTAGE - Control can operate equally well with stoichiometric fuel/air ratios and with relatively large excess of O2 in exhaust gas.
