Abstract

The system involves injecting air compressed to the required pressure in the combustion chamber before injection of fuel. The compressed air is obtained by a compressor actuated by a motor and it is stored under high pressure in a chamber. The inlet valve is replaced by a compressed air inlet valve. The piston moves away from the cylinder during the ignition and returns during the exhaust phase. On exiting the high pressure turns the turbines which drives the injector pump, the magneto feeding the spark plugs and the other necessary accessories. The first two phases of suction and compression, are thus suppressed and the piston only follows the ignition and exhaust stroke.

Description

- 1 -.- 1 -.

La présente invention concerne les moteurs à combustion interne à quatre  The present invention relates to internal combustion engines with four

phases dites "cycle de Beau de Rochas".  so-called "Beau de Rochas cycle".

Dans les moteurs à injection, les phases aspiration et compression ne servent qu'a obtenir l'air comprimé dans lequel, à la fin de la phase compression, le carburant sera injecté. Ce n'est pas rationnel. L'invention consiste à injecter de l'air comprimé à la pression requise  In injection engines, the suction and compression phases only serve to obtain the compressed air into which, at the end of the compression phase, the fuel will be injected. It is not rational. The invention consists in injecting compressed air at the required pressure

dans la chambre d'explosion avant d'y injecter le carburant.  in the explosion chamber before injecting fuel into it.

Cet air comprimé est obtenu par un compresseur actionné par le moteur et il est stocké à haute pression dans un réservoir approprié. Une sortie par valve tarée alimente le moteur à la pression convenable. Des sorties à haute pression alimentent des turbines qui font fonctionner la pompe de l'injecteur, la magnéto alimentant le dispositif d'allumage et les autres  This compressed air is obtained by a compressor activated by the engine and it is stored at high pressure in a suitable tank. A calibrated valve outlet supplies the motor at the correct pressure. High pressure outlets supply turbines which operate the injector pump, the magneto supplying the ignition device and others

accessoires nécessaires.necessary accessories.

Les deux premières phases, aspiration et compression, devenues inutiles, sont supprimées et le piston ne fait qu'un seul mouvement alternatif par cycle, il s'éloigne de la culasse pendant l'explosion puis s'en rapproche pendant l'échappement. La bielle ne fait faire au vilbrequin qu'un seul tour par cycle explosion/échappement. La soupape d'admission est supprimée et remplacée par la valve tarée d'arrivée de l'air comprimé, la soupape  The first two phases, suction and compression, which have become unnecessary, are eliminated and the piston makes only one reciprocating movement per cycle, it moves away from the breech during the explosion and then approaches it during the exhaust. The connecting rod makes the crankshaft make only one turn per explosion / exhaust cycle. The intake valve is removed and replaced by the calibrated compressed air inlet valve, the valve

d'échappement subsiste.exhaust remains.

Le moteur pourra comporter une pompe manuelle ou autre pour rétablir la pression de l'air comprimé en cas de baisse accidentelle de celle-ci, ladite pompe pouvant être remplacée par une source extérieure d'air comprimé. Le moteur pourra comporter plusieurs cylindres et un dispositif assurant le démarrage en distribuant l'air comprimé dans les cylindres en fonction  The engine may include a manual or other pump to restore the pressure of the compressed air in the event of an accidental drop thereof, said pump being able to be replaced by an external source of compressed air. The engine may include several cylinders and a device ensuring starting by distributing the compressed air in the cylinders as a function

de la position des pistons lorsque lemoteur est à l'arrêt puis en mouvement.  the position of the pistons when the engine is stopped and then moving.

Le moteur pourra comporter une commande du distributeur de l'air comprimé  The engine may include a control of the compressed air distributor

par un organe électronique programmé en conséquence.  by an electronic device programmed accordingly.

Ie moteur pourra comporter une commande du dispositif d'injection de car-  Ie engine may include a command of the car injection device

burantetd'allumage par un organe électronique programmé en conséquence.  power and ignition by an electronic device programmed accordingly.
