Abstract
A control apparatus for an engine comprises an air-fuel ratio sensor for detecting an air-fuel ratio on the basis of an exhaust gas component from the engine, a fuel controller which receives an output from the air-fuel sensor so as to feed-back-control a fuel quantity in response to the operating conditions of the engine so that the air-fuel ratio becomes optimum, a fuel supplier to supply fuel on the basis of a signal from the fuel controller, and a target advance angle value changer which selects a fixed advance angle value for ignition timing independent from the operating conditions of the engine when an instruction signal for adjusting the ignition timing is generated from an ignition timing adjustment signal generator, an ignition device which effects ignition in accordance with an output from the target advance angle value changer, and a feed-back control stopping device which stops the feed-back control of the air-fuel ratio when the instruction signal is generated from the ignition timing adjustment signal generator.
