Abstract
An engine controlling system is operative to control injection of fuel into an engine and an ignition timing thereof in accordance with predetermined maps, respectively. Each map is at a lattice pattern showing predetermined relationship between engine speed and load value determined based on the engine speed and an engine intake air flow in terms of mass flow. When the degree of the throttle valve opening is greater than a predetermined value and the engine speed and the load value read on the maps do not fall in power zones in the maps, the engine controlling system operates to increase the fuel supply and retard the ignition timing so that the increased rate of fuel supply and the retarded ignition timing fall in the power zones in the maps to prevent occurrence of a knock.
