Title
(EN) TWO-STROKE ENGINE WITH CONTROLLED VALVES
(FR) MOTEUR DEUX TEMPS A SOUPAPES COMMANDEES
Abstract
(EN)
Two-stroke engine with controlled valves comprising at least one cylinder (2) having a combustion chamber (9) supplied with fresh air by means of a volumetric compressor and provided at its higher part (8) with at least one intake port (10) co-operating with one intake valve (11). This two-stroke engine is characterized in that its timing gear is effected, independently of the geometry of the cylinder (2), by means of controlled timing means (21). The invention relates to the industry of fuel engines.
(FR)
Moteur deux temps à soupapes commandées comportant au moins un cylindre (2) possédant une chambre de combustion (9) alimentée en air frais par un compresseur volumétrique et pourvue à sa partie supérieure (8) d'au moins un orifice d'admission (10) coopérant avec une soupape d'admission (11). Ce moteur deux temps est caractérisé par le fait que sa distribution est assurée, indépendamment de la géométrie du cylindre (2), par des moyens de distribution (21) commandés. L'invention concerne l'industrie des moteurs à carburants.
