Fuel controller with an adaptive adder

摘要

An electronic engine control system incorporates an electronic fuel controller for adaptively altering the amount of fuel delivered to an internal combustion engine. The fuel controller detects the oxygen level contained in the engine's exhaust emissions along with the engine speed, or engine angular velocity, load and other engine operating parameters and varies the fuel delivery in accordance with the detected parameters. The change in fuel delivery is stored in a table contained in a memory. The information stored in the table is utilized by the fuel controller as an addend to a fuel delivery value calculated from the detected operating parameters.
