<p>A composite electronic circuit accurately controls air-fuel ratio in an engine having an electronically regulated fuel supply, such as an electronically regulated fuel injection system. The air-fuel ratio is measured by an oxygen sensor connected to the exhaust manifold. A circuit associated with the oxygen sensor compensates for variations in sensor output produced by temperature change during warm-up. After engine warm-up is completed, the circuit provides a voltage having a value independent of engine temperature.</p> |
