Title
(EN) TWI-STROKE CYCLE ENGINE CYLINDER CONSTRUCTION
(FR) STRUCTURE DE CYLINDRE POUR MOTEURS A DEUX TEMPS
Abstract
(EN)
A cylinder construction for an internal-combustion two-stroke engine, having multiple intake ports (8), multiple intake valve ports (11) and multiple exhaust ports (3). The cylinder enables a two-stroke engine to run on gasoline without premixing it with lubricating oil and, due to its optimal volumetric efficiency and good separation of air-fuel mixture and exhaust gases, provides the possibility to satisfy requirements for high fuel efficiency, high power output and low emissions released into the atmosphere. An engine using this cylinder construction will be lightweight, will not require valve trains and camshaft and can be manufactured with any number of cylinders. Utilizing a slightly different process and slightly different configuration, the present invention will also enable a two-stroke engine to run on diesel fuel and produce significant benefits in comparison to existing two-stroke diesel engines.
(FR)
L'invention se rapporte à une structure de cylindre pour moteurs à combustion interne à deux temps, qui comprend des orifices d'admission multiples (8), des orifices à soupapes d'admission multiples (11) et des orifices d'échappement multiples (3). Un tel cylindre permet de faire fonctionner un moteur à deux temps à l'essence sans qu'il soit nécessaire de mélanger celle-ci préalablement avec une huile lubrifiante, et, en raison de son rendement volumétrique optimal et de ses bonnes caractéristiques de séparation entre le mélange air/carburant et les gaz d'échappement, offre la possibilité de satisfaire des exigences telles qu'une économie de carburant élevée, une puissance de sortie élevée et une faible émission de polluants dans l'atmosphère. Un moteur qui utilise cette structure de cylindre est d'un poids léger, ne nécessite ni trains de soupapes ni arbre à came et peut être fabriqué avec n'importe quel nombre de cylindres. En utilisant un procédé légèrement différent et une configuration légèrement différente, la présente invention permet également de faire fonctionner un moteur à deux temps au carburant diesel et d'obtenir des avantages considérables par rapport aux moteurs diesel à deux temps existants.
