Abstract

L’invention concerne un moteur à cycle deux temps comportant un carter caractérisé en ce que sa forme est de type “cuillère” pour chaque demi carter pour permettre de guider le flux de gaz frais et améliorer le refroidissement du piston. The invention relates to a two-stroke cycle engine comprising a crankcase characterized in that its shape is of the “spoon” type for each crankcase half to allow the flow of fresh gases to be guided and to improve the cooling of the piston.

Description

Dispositif d'amélioration du guidage des gaz frais à l'intérieur du carter pompe d'un moteur 2 Temps.Device for improving fresh gas guidance inside the pump housing of a 2-stroke engine.

Habituellement le flux de gaz frais va terminer sa trajectoire au delà de la bielle, sur la face intérieure de la jupe avant du cylindre et sous le piston.Usually the flow of fresh gas will end its trajectory beyond the connecting rod, on the inside face of the front cylinder skirt and under the piston.

Il s'agit d'une innovation pour les moteurs à cycle 2 Temps. Elle fait partie intégrante du carter moteur, ou peut aussi être une pièce rapportée. Elle permet de guider la quasi intégralité du flux sortant de l'admission en direction des couloirs de transferts sur les cotés, afin de conserver une vitesse maximale du flux jusqu'à la phase de balayage, et améliorer egalement le refroidissement du piston en faisant office de deflecteur vertical dans sa partie centrale.This is an innovation for 2-stroke cycle engines. It is an integral part of the crankcase, or can also be an added part. It makes it possible to guide almost all of the flow leaving the admission in the direction of the transfer corridors on the sides, in order to maintain a maximum speed of the flow until the sweeping phase, and also improve the cooling of the piston by acting as vertical deflector in its central part.

Précisions : Details :

Chaque demi carter comportera une cuillère (voir ) particulièrement recourbée dans sa partie supérieure, permettant de rediriger le flux vers les couloirs de transferts sur les cotés (Voir ).Each crankcase half will include a spoon (see ) particularly curved in its upper part, allowing the flow to be redirected towards the transfer corridors on the sides (See ).
