摘要

"AIR / FUEL RELATIONSHIP CONTROL SYSTEM FOR AN INTERNAL COMBUSTION ENGINE AND PROCESS TO REDUCE EMISSIONS AND INCREASE THE EFFICIENCY OF AN INTERNAL COMBUSTION ENGINE". An air / fuel ratio control system for an internal combustion engine, to reduce emissions and increase engine efficiency, includes an ionization device to detect and measure ionization within a combustion cylinder and generate an ionization signal. based on detection and measurements. An air / fuel ratio controller in electrical communication with the ionization device is also included. The controller receives the ionization signal and controls the air / fuel ratio in the engine, based, at least in part, on the ionization signal. in a preferred mode of the control system, the controller controls the air / fuel ratio based on a first local peak in the ionization signal. In another mode, the controller controls the air / fuel ratio based on maximizing the first local peak in the ionization signal.
