Abstract

The fuel economiser has a manual regulator which is located between the carburettor and the inlet pipe. The economy is made by rotating the regulator to a fixed position. A secondary economy is made automatically under the high engine rating suction conditions. In this case the air fuel mixture passes in a serpentine path over a number of baffles which improve the mixing of the air and fuel. The automatic device has a cone fitted inside a collar. The cone has a number of side windows. The cone has an internal return spring.

Description

a) Titre de l'invention : D - R - C - C (Double Régulateur de Consommation de Carburant). a) Title of the invention: D - R - C - C (Dual Fuel Consumption Regulator).

b) La présente invention concerne les appareils de type "économiseur d'essence. I1 comporte deux systèmes de régulation
1.- Un réglage manuel permettant d'augmenter, de maintenir ou de diminuer sensiblement la puissance.b) The present invention relates to devices of the "fuel saver" type. It comprises two regulation systems
1.- Manual adjustment to increase, maintain or decrease the power significantly.

20- Une régul-ltion automatique qui diaphragme partiellement le passage direct, ce qui en diminuant le débit oblige le mélange à passer dans les chicanes afin d'bure broyé et malaxé. 20- An automatic regul-ltion which partially diaphragm the direct passage, which by decreasing the flow rate obliges the mixture to pass through the baffles in order to grind and knead.

c) Les moteurs à explosion propulsant les véhicules automobiles dans les vitesses autorisées utilisent 20 ,0 de carburant inutillement. En effet, lorsque le véhicule a atteint sa vitesse de croisière et que le moteur tourne à haut régime, il est possible de réduire la consomtliation d'énergie, sans diminuer pour autant la vitesse, la dépense énergétique entant surtout nécessaire pour le lancement au départ du véhicule. D'une autre façon, qui la n'entre pas dans le fonctionnement du moteur, les constructeurs généralisent autuellement l'emploi d'une cinquième vitesse ou surmultipliée. Le moteur tourne moins vite et de ce fait il y a un nombre inférieur d'aspiration, la dépense en volume de mélange est moindre et malgré cela la vitesse est maintenue. c) Internal combustion engines propelling motor vehicles at authorized speeds use 20.0 of fuel unnecessarily. Indeed, when the vehicle has reached its cruising speed and the engine is running at high speed, it is possible to reduce the energy consumption, without reducing the speed, the energy expenditure being mainly necessary for launching at departure of the vehicle. In another way, which does not enter into the functioning of the engine, the manufacturers generally generalize the use of a fifth speed or overdrive. The engine runs slower and therefore there is a lower number of aspiration, the expenditure in mixing volume is less and despite this the speed is maintained.

d) Ce dispositif permettant d'économiser plus ou moins de carburant a deux propriétés :
1 - I1 permet une économie de carburant grâce à une possibilité de réglage manuel au moment de la pose (sur la bride entre le carburateur et la pipe d'admission) selon que l'on oriente les chicanes ou les piliers en direction de l'admission.d) This device making it possible to save more or less fuel has two properties:
1 - I1 saves fuel thanks to the possibility of manual adjustment at the time of installation (on the flange between the carburetor and the intake pipe) depending on whether the baffles or the pillars are oriented towards the admission.

2 - La deuxième régulation étant automatique, sous l'effet de la de pression à haut régime, le dispositif intérieur (noyau et ressort) diaphragment le passage direct et obligent les gazs à se triturer sur les chicanes latérales, ce qui rend le mélange plus hétérogène, donc plus détonnant et moins polluant. 2 - The second regulation being automatic, under the effect of the pressure at high speed, the internal device (core and spring) diaphragms the direct passage and forces the gases to grind on the side baffles, which makes the mixture more heterogeneous, therefore more explosive and less polluting.

e) I1 comprend un tronc de cône en laiton surmonté dans son grand diamètre d'une collerette. I1 est percé latéralement de plusieurs fenêtres rectangulaires horizontales ce qui laisse sur le périmètre deux parties pleines nommées "piliers". La partie intérieure et le petit diamètre sont percés. Ce dispositif est muni à l'intérieur d'un ressort de forme conique pointe en haut, surmonté d',n dispositif de forme chapeau chinois ou à ailettes (selon modèle) appelé "noyau". Le noyau et le ressort compressible diaphragment partiellement l'orifice de la base du tronc de cône, sous l'effet de la dépression. e) It comprises a truncated cone of brass surmounted in its large diameter by a collar. I1 is pierced laterally with several horizontal rectangular windows which leaves on the perimeter two solid parts called "pillars". The inner part and the small diameter are drilled. This device is provided inside with a conical spring point pointed at the top, surmounted by, a Chinese hat-shaped device or with fins (according to model) called "core". The core and the compressible spring partially diaphragm the orifice of the base of the truncated cone, under the effect of vacuum.

f) Le dispositif peut être utilisé sur tous les moteurs à explosion à système d'alimentation par carburation dans le but d'économiser la dépense en énergie et d'éviter l'engorgment et la pollution. f) The device can be used on all internal combustion engines with a fuel-supply system in order to save energy expenditure and avoid clogging and pollution.

Claims

REVS ATIONS

This device for reducing fuel consumption in internal combustion engines with a carburetion system is a double developer.

The first adjustment is done manually when the device is installed (between the carburetor and the intake pipe) depending on whether the baffles or pillars are oriented towards the intake.

The second regulation is automatic. Under the effect of the high speed vacuum, the device diaphragm the direct passage forcing the gases to grind on the side baffles.

Characterized by the fact that this device is adjustable at the iris e place in order to maintain or reduce the power.

Characterized by the fact that this device includes an automatic regulation system acting under the effect of depression which is important at high speed.

The engine, once started, can run on less fuel. This regulation is obtained thanks to the concave conical or finned core (depending on model). The core imposes pressure on the spring by crushing it. The turns approaching, diaphragm the direct lower orifice. The flow is less, hence saving. In addition, this phenomenon forces the mixture to pass forcefully through the side baffles causing the hydrocarbon molecules to burst. This kneaded mixture is more heterogeneous and therefore more explosive and less polluting.
