Abstract

Compact two-stroke valve engine with supercharging by opposed pistons whose object is to increase the energy of the unit by recovering part of the burnt gases. It is composed of two opposed pistons 4 and 6 whose axes 5 and 7 slide inside each other, and are connected at their base by two connecting rods 19 assembled to the two opposed crank pins of the crankshaft 20. This compact engine block has a use in the industry for producing diesel or other internal combustion engines.

Description

La présente invention concerne un moteur mixte à explosions à double usage, à carburant et Diesel-par modification de la culasse avec un cycle moteur deux temps. ( soit par changement de la culasse (23) ou cale d'épaisseur,de façon à modifier le taux de compression. Ce bloc moteur permet la récupération d'une partie des gaz bru lés par le retard à la fermeture de la soupape d'échappement (2) -la récupération des gaz d'échappement se fait,directement)sur une roue à aubes fixée sur l'arbre moteur pour augmenter la puissance motrice. The present invention relates to a dual-use dual-fuel explosion engine with fuel and diesel by modifying the cylinder head with a two-stroke engine cycle. (either by changing the cylinder head (23) or shim, so as to modify the compression ratio. This engine block allows the recovery of part of the burnt gases injured by the delay in closing the exhaust (2) -exhaust gas recovery is done directly) on an impeller fixed on the motor shaft to increase the driving power.

Ce bloc moteur compact se compose d'un moteur classique avec compresseur suralimenté. This compact engine block consists of a conventional engine with supercharged compressor.

La turbine de récupération des gaz se trouve à la sortie de la pipe d'échappement directement fixée sur le boiter de distribution,en tête du cylindre afin d'augmenter l'énergie du groupe. The gas recovery turbine is located at the outlet of the exhaust pipe directly attached to the distribution box, at the head of the cylinder in order to increase the group's energy.

Ainsi,ce bloc compact se composed'un piston moteur (4) dont la fonction est compression et détente et d'un deuxième piston (6) dont le but est l'admission et la pré-compression ,balayage des cran, cêp deux pistons (4) et (6) sont montés sur deux axes tubulaires (5- et 7 - qui sont guidés par une embase fixe de guidage (24) . Cet ensemble est intercalé entre le cylindre et le carter en lui donnant une position bien rectiligne. Thus, this compact block is composed of a driving piston (4) whose function is compression and expansion and of a second piston (6) whose purpose is the admission and the pre-compression, notch sweeping, two-piston cêp (4) and (6) are mounted on two tubular axes (5- and 7 - which are guided by a fixed guide base (24). This assembly is interposed between the cylinder and the casing giving it a well rectilinear position.

L'ensemble des axes des pistons (5) et (7) ceux-ci sont reliés à leur base par deux bielles (I9) assemblées sur deux manetons opposés du vilebrequin ( 20 ). All the axes of the pistons (5) and (7) these are connected to their base by two connecting rods (I9) assembled on two opposite crank pins of the crankshaft (20).

Bien entendu,l'invention sera bien comprise en se référant au texte décrit et aux dessins annexés à titre d'exemple,indi catit non limitatif et sont sujets à de nombreuses variantes de réalisations et d'applications comme produit industriel nouveau. Of course, the invention will be well understood with reference to the text described and to the accompanying drawings by way of example, which are non-limiting and are subject to numerous variants of embodiments and applications as a new industrial product.
