Sound and vibration damping device based on tires

The method comprises, after the end of the normal combustion of the mixture in the combustion chamber of the engine, establishing a post-combustion by maintaining a series of high-tension sparks during a long period and introducing turbulent additional air in the vicinity of said sparks so as to form a plasma which is propagated in said residual mixture. The plasma is propagated in the cylinder from a plurality of points, that is to say partly from a point near to the spark and partly from at least another point of the combustion chamber.

Method for reducing pollution due to an internal combustion engine

An auxiliary chamber or ignition 'prechamber' for afterburners of aeronautical turbine engines draws in, through a perforated plate, a carbureted mixture produced by fuel projected against an anvil by an injection manifold, and the injection manifold also issues a jet of fuel into a tube which discharges into the chamber downstream of a spark plug. The produced flame is guided into a flame stabilizer.

Device for igniting fuel injected into a rapidly flowing gaseous medium

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.

Process for reducing the pollution due to an internal combustion engine,

A device for injecting and igniting a fuel in a flow of air, comprising a bular duct in which are generated an internal flow of rotating air and an intermediate flow containing fuel which is sandwiched between the internal flow and an external flow of rotating air, in which ignition is effected by a central electrode placed in the axis of the tubular duct and defining within the latter an annular channel which narrows around the downstream end of the central electrode to form an annular gap of uniform width along the entire extent of its circumference, in such a way that a difference in electrical potential applied between the electrode and the tubular duct causes sparks to jump between the free end of the electrode and the tubular duct across the internal flow and the intermediate flow.
