Fuel ratio control for IC engine with electronic fuel injection - detects individual operating parameters for each engine cylinder and uses microprocessor to evaluate them

摘要

The fuel ratio control, has a sensor (8) detecting the quantity of air (Qa) fed to one of the engine cylinders (24), a signal processor (16) providing a signal representing the engine revs (N) and a sensor (18) providing a mixture ratio signed for the exhaust from each engine cylinder (24). A microprocessor evaluates the measured parameters to calculate the fuel quantity for each fuel injection jet (22), with independent regulation of the individual fuel injetcion jets (22). ADVANTAGE - Accurate fuel injection regulation for each individual engine cylinder.
