Abstract
Disclosed herein is an ignition timing controller for a sparing engine. The controller is equipped with a variable swirl forming device for changing over the state of swirling of air, which is flowing into an intake port, in accordance with the operation zone of the engine, so that an optimal control of ignition timing is assured even at the time of malfunction of the variable swirl forming device or during a transition period such as a delay in response by the variable swirl device. The controller is hence equipped additionally with an ignition timing setting device for receiving information on the operation zone of the engine and setting ignition timing information corresponding to the state of swirling on the basis of the information on the operation zone, a swirl detection device for detecting the actual state of operation of the variable swirl forming device, and a swirl ignition timing correction device for permitting further correction of the ignition timing information from ignition timing setting device on the basis of a detection signal from the swirl detecting device.
