Abstract
The process comprises producing in a combustion chamber of the engine a high-tension electrical discharge, prolonging the duration of the discharge, and supplying additional air in the vicinity of the discharge so as to form a plasma and cause a post-combustion in the cylinder. An internal combustion engine is disclosed which carries out this process. The engine comprises for each cylinder a high-tension ignition spark plug and an air supply conduit in the vicinity of the high-tension electrode of the spark plug. Valve means open the conduit at least during the driving stroke of the piston. An electric supply circuit for the spark plug comprises an ignition distributor having a rotary contact of such dimension that it maintains the supply of current to the spark plug during at least a part of the expansion stroke of the piston.
