Abstract

The present invention relates to a two-cylinder internal combustion engine in which the combustion chambers may be allowed to communicate. This two-cylinder engine allows the energy lost to be reduced, to a certain degree, by lowering the temperature at the end of combustion. This motor is made up of two cylinders: a cylinder 1 and a cylinder 2 in which there move respectively a piston 5 and a piston 6. These pistons transmit, via a connecting rod-crank system 12 or any other device, the quantity of work delivered by the expansion of the gases inside the combustion chambers 7 and 8. One or more transfers 4 allow an exchange between the two combustion chambers when the valve 3 is open. The valves 9 and 10 are respectively the inlet and exhaust valves of the cylinders 1 and 2. Either a device allowing controlled ignition or an injector 11 is fitted to the cylinder head.

Description

Moteur bicylindre à explosion interne à chambres de combustion interactives
La présente invention concerne un moteur à combustion interne à deux cylin- dres dont les chambres de combustion peuvent être mises en communication.Internal combustion twin-cylinder engine with interactive combustion chambers
The present invention relates to an internal combustion engine with two cylinders, the combustion chambers of which can be brought into communication.

Actuellement,le rendement des moteurs à explosion interne est feible et une grande partie de l'énergie est perdue dans le circuit de refroioissement et dans les gaz d'échappement. Currently, the efficiency of internal combustion engines is low and much of the energy is lost in the cooling circuit and in the exhaust gases.

Ce moteur bicylindre permet de reduire dans une certaine mesure cette energie perdue en abaissant la temperature en fin de combustion et en amelio- rant le rendement thermodynamique du cycle. This twin-cylinder engine allows this lost energy to be reduced to a certain extent by lowering the temperature at the end of combustion and by improving the thermodynamic efficiency of the cycle.

Ce moteur est constitué de deux cylindres: Un cylindre 1 et un cylindre 2 dans lesquels se deplacent respectivement un piston 5 et un piston 6.Ces pistons transmettent par un systeme bielle manivellei2outout autre dispositif la quantité de travail delivrée par la détente des gaz à l'intérieur des chambres de combustion 7 et 8.Un ou des transferts 4 permettent un échange entre les deux chambres de combustion lorsque la soupape 3 est ouverte.Les soupapeS10 et 9 sont respectivement les soupapes d'admission et d'échappement des cylindre et 2.Sur la culasse du cylindre est adaptée soit un dispositif permettant un allumage commandé soit un injecteur il.  This engine consists of two cylinders: A cylinder 1 and a cylinder 2 in which a piston 5 and a piston 6 move respectively. These pistons transmit by a crank rod system2 or any other device the amount of work delivered by the expansion of the gases to the interior of the combustion chambers 7 and 8. One or more transfers 4 allow an exchange between the two combustion chambers when the valve 3 is open. The valves S10 and 9 are respectively the intake and exhaust valves of the cylinders and 2 .On the cylinder head is fitted either a device allowing a controlled ignition or an injector there.

Le cycle de fonctionnement de chaque cylindre peut être soit un cycle à deux temps soit à quatre temps à allumage commandé ou a injection liquide de combustible. (moteur diesel)
Les deux pistons se déplacent dans le même sens et effectuent un cycle dans le même temps avec un leger ou sans décalage de cycle.The operating cycle of each cylinder can be either a two-stroke or a four-stroke cycle with controlled ignition or with liquid fuel injection. (diesel motor)
The two pistons move in the same direction and cycle at the same time with a light or without cycle offset.

Un moteur bicylindre à chambres de combustion interactives à quatre temps à allumage commandé respecte les phases suivantes:
Phase d'admission:
On injecte dans le cylindre 1 un mélange: aíressence et dans le cylin
dre 2 soit de l'air soit un mélange: airessence trés riche en air pour
repousser les limites d'inflammabilités de ce mélange afin d'utiliser
des rapports volumiques importants.Pendant cette phase de remplissage
la soupape 3 est fermée. A two-cylinder engine with interactive four-stroke combustion engines with positive ignition respects the following phases:
Admission phase:
A mixture is injected into cylinder 1: aíressence and into the cylin
dre 2 either air or a mixture: airessence very rich in air for
extend the flammability limits of this mixture in order to use
important volume ratios. During this filling phase
valve 3 is closed.

Phase de compression:
La soupape 3 reste fermée.La compression s'effectue par la remontee
des pistons jusqu'à leur point mort haut.Compression phase:
Valve 3 remains closed. Compression takes place by ascent
pistons to their top dead center.

Phase d'explosion:
L'explosion a lieu dans le cylindre 1 et se propage dans le cylindre
2 apres l'ouverture de la soupape 3.Explosion phase:
The explosion takes place in cylinder 1 and propagates in cylinder
2 after opening the valve 3.

L'allumage peut se faire de tois facons differentes:
Allumage commande par etincelle:
On enflamme les gaz par une étincelle.L'ouverture de la soupape
3 intervient pendant ou au début de .'explosion des gaz.The lighting can be done in three different ways:
Ignition controlled by spark:
The gas is ignited by a spark The opening of the valve
3 occurs during or at the start of the gas explosion.

Allumage par onde de choc:
Si la différence de pression entre les gaz des deux cylindres est
suffisante;en ouvrant la soupape 3 on crée une onde de choc de com
pression qui enflammera le combustible a une treks grande vitesse.Shock wave ignition:
If the pressure difference between the gases of the two cylinders is
sufficient; opening valve 3 creates a shock wave of com
pressure that will ignite the fuel at high speed treks.

Allumage mixte:
Les gaz commencent par s'enflammer sous l'effet d'une étincelle
puis la combustion est accélérée par l'ouverture de la soupape 3
qui autorise la propagation d'une onde de choc de compression crée,si
elle est suffisante,par la difference de pression entre les gaz des
deux cylindres.Mixed ignition:
The gases start to ignite under the effect of a spark
then combustion is accelerated by the opening of valve 3
which allows the propagation of a compression shock wave created, if
it is sufficient, by the difference in pressure between the gases of
two cylinders.

Phase de détente:
La soupape 3 reste ouverte.La détente des gaz s'effectue jusqu'au point
mort bas des pistons.Relaxation phase:
Valve 3 remains open; gas expansion takes place to the point
dead pistons.

Phase a d'échappement:
L'échappement se fait par la remontée des pistons qui refoulent les
gaz de combustion a l'exterieur des cylindres.Puis un autre cycle commen
ce. Exhaust phase:
The exhaust is made by the ascent of the pistons which repel the
combustion gases outside the cylinders. Then another cycle begins
this.
