Abstract

An internal combustion engine with applied ignition which includes at least one main combustion space and one ignition chamber coordinated to a respective main combustion space and connected therewith by way of an overflow channel and provided with a spark plug and an injection valve, and a fuel supply system for the ignition chamber independent of the fuel supply for the main combustion spaces which operates in such a manner that a fuel quantity is injected into the associated ignition chamber during a low pressure phase of the corresponding main combustion space; an electromagnetically actuatable valve which is electrically controllable in accordance with the ignition sequence of the internal combustion engine is thereby coordinated to each injection line whereby the electric control of the actuating magnets of the electromagnetically actuated valves takes place by way of a switch actuated by a cam rotating at a speed proportional to the engine rotational speed; the switch, in turn, is adapted to be changed in its spacing to the cam surface to thereby change the amount of fuel injected into the ignition chamber.
