  • the working piston / 2 / of the engine is in the TDC while the compressor piston H I is at the most far removed and owing to the vacuum created in the inner space of the working piston 12/ a sucking of air-fuel mixture is produced by the intake port /9 / and the overflow ports / 14/ through the valve / 10 / and the intake port / l l / , the fuel is injected by the nozzle / 16/ and making an air-fuel mixture is taking place. All this air -fuel mixture is compressed in the inner space as a result of the displacement of the working piston 12 / downwards to the BDC, according to the Figure 2.
  • the high-efficiency operation of the engine is achieved owing to the coordination of a series of constructive and physical factors such as: lack of casing sucking and compressing; a reduced length of the sucking track; an absence of useless constructive spaces ; a simplified crank mechanism and less number of friction details, as well as the operation as a double- stroke engine with pure fuel without oil.

Abstract

L'invention concerne un moteur à combustion interne. La partie supérieure du moteur contient un piston de fonctionnement (2) relié par l'intermédiaire d'un embiellage (3) au palier correspondant (4) sur un vilebrequin (5) placé dans la partie inférieure du moteur. Ladite partie inférieure se présente sous la forme d'un boîtier (6), tandis que le piston de compression (7) est situé à l'intérieur de l'espace intérieur du piston de fonctionnement (2). Le piston de compression (7) est fixé à la partie supérieure du moteur (1) par l'intermédiaire d'une tige creuse (8) dont l'orifice de transfert intérieur (9) est placé au-dessous de la soupape d'admission (10). Ce moteur est caractérisé par le fait qu'il est un moteur deux temps mais qu'il fonctionne avec du carburant pur sans apport d'huile, la lubrification étant forcée comme dans le moteur quatre temps. On peut donc utiliser ce type de moteur en tant que moteur à essence ou moteur diesel.
