Abstract
PURPOSE:To prevent the errorneous judgement of the switching from a regular map to a high octane number map and improve the operation performance by controlling the combustion state for each kind of fuel and suspending the switching judgement of maps when the correction for the ignition timing is carried out. CONSTITUTION:The operation state of an engine is detected by a means (a), and the knocking generated in the engine is detected by a means (b). A fundamental control value for controlling the fuel state is set for each fuel having different octane number is set by a means (c), and said control value is stored in a map. Switching from a low octane number map to a high octane number map is instructed by the first means (d), and the switching judgement is suspended on the prescribed correction of ignition timing. While, the switching from the high octane number map to the low octane number map is instructed by the second means (e). Further, on the basis of the fundamental control value of the selected map, a means (f) controls a means (g) for operating the combustion state of the engine.
