    • 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.

    • In an acceleration pump of a carburetor for an internal combustion engine including a cylinder and a piston reciprocatorily inserted in the cylinder, the piston is formed in its upper portion with a transverse bore for a stopper member to extend therethrough to be urged by a heat sensitive element to move in a direction at right angles to the direction of reciprocatory movement of the piston, so that additional fuel for acceleration can be supplied to the engine in a quantity which is accurately corrected to accommodate itself to changes in ambient temperature, by means of the heat sensitive element. The transverse bore is formed at its top wall and bottom wall with projections, and the stopper member is formed at its upper surface and lower surface with depressed portions, so as to enable the lengths of the downward and upward strokes of the piston to be controlled in accordance with changes in ambient temperature. Thus the acceleration pump is capable of supplying to the engine additional fuel for acceleration in a quantity which is corrected to accommodate itself for changes in ambient temperature.
