Title
(EN) COMPRESSED TWO-STROKE OR FOUR-STROKE INTERNAL COMBUSTION ENGINE
(FR) MOTEUR COMPRESSE A COMBUSTION INTERNE A DEUX OU A QUATRE TEMPS
Abstract
(EN)
The invention concerns a two-stroke or four-stroke internal combustion engine (M1) operating by intake of air-fuel mixture or by intake of fresh air with direct or indirect fuel injection, the engine comprising at least a cylinder (1) defining a combustion chamber with variable volume, wherein moves in reciprocating motion an engine piston (4) coupled by a connecting rod (7) to the pin (8) of a crankshaft (9), and a compressor (14) associated with each cylinder to provide a supercharging of the cylinder with air-fuel mixture or fresh air. The invention is characterised in that said compressor is a compressor comprising at least a stage, in the compression chamber (14a, 14b) whereof moves a compressor piston (112), which is coupled to the crankshaft by a connecting rod (111) articulated on an eccentric member (10), said eccentric member being mounted on said crank shaft.
(FR)
Moteur à combustion interne à deux ou à quatre temps (M1), fonctionnant par admission de mélange carburé ou par admission d'air frais avec injection directe ou indirecte de carburant, le moteur comportant au moins un cylindre (1) définissant une chambre de combustion à volume variable, dans laquelle se déplace alternativement un piston de moteur (4) qui est attelé par une bielle (7) au maneton (8) d'un vilebrequin (9), et un compresseur (14) associé à chaque cylindre pour obtenir une suralimentation du cylindre en mélange carburé ou en air frais, caractérisé par le fait que ledit compresseur est un compresseur comportant au moins un étage, dans la chambre de compression (14a, 14b) duquel se déplace un piston de compresseur (112), qui est attelé au vilebrequin par une biellette (111) articulée sur un excentrique (10), ledit excentrique étant monté sur l'arbre dudit vilebrequin.
