Abstract

Solenoid valve control device for carburettor engine comprising: - a first stage 1 of means making it possible to receive information from the contact-breaker and to carry out the electronic adaptation of the signals received; - a second stage 2 is slaved to associated cells in order to obtain an electrical voltage directly related to the frequency of the pulses emitted by the contact-breaker, hence to the engine speed; - a speed comparator 3 associated with a switch of the accelerator pedal; - a transistor power control 4. Application for reducing petrol consumption.

Description

La presente invention- concerne un dispositif permettant de diminuer la consommation de carburant des moteurs compor tant un carburateur, et plus particulièrement des automobiles. The present invention relates to a device for reducing the fuel consumption of engines comprising a carburetor, and more particularly automobiles.

On sait que pour diminuer la consommation d'essence, il faut admettre de l'air supplémentaire immédiatement après le carburateur, afin de casser la dépression qui s'y produit normalement dès que 'e conducteur d'une automobile loche l'accélérateur. Si on ne casse pas la dépression, le moteur aspire le mélange carburant par le canal du ralenti en une quantité supérieure a-ce qui est nécessaire, provoquant en -outre une certaine pollution. It is known that to reduce fuel consumption, it is necessary to admit additional air immediately after the carburettor, in order to break the depression that normally occurs there as soon as the driver of an automobile looses the accelerator. If we do not break the vacuum, the engine sucks the fuel mixture through the idle channel in a larger amount than is necessary, causing in addition some pollution.

On a déjà eu l'idée de faire arriver l'air supplémentaire en tête du carburateur, par exemple à l'aide d'une bride sup plémentaire traversée par un tube d'arrivée d'air. Ce tube d'arrivée d'air peut être fermé à l'aide d'un papillon d'électro-vanne commandé par l'enfoncement de la pédale d'accéléra- teur. Lorsque le papillon s'ouvre, de l'air supplémentaire s'introduit dans le carburateur bloquant ainsi l'arrivez di carburant. It has already been thought to have the additional air arrive at the head of the carburettor, for example by means of an additional flange through which an air inlet tube passes. This air inlet tube can be closed by means of a solenoid valve throttle controlled by depressing the accelerator pedal. When the throttle opens, additional air is introduced into the blocking carburetor and the fuel arrives.

Ce dispositif n'a cependant pas connu le suces esp!r3 pour diverses raisons, notamment le risque de calage du moteur au ralenti. This device has however not known sucs esp! R3 for various reasons, including the risk of engine stall idling.

Pour remédier å cet inconvénient et à d'autres, l'inven-- teur a mis au point un dispositif de commande de l'électro- vanne par des moyens électroniques comportant un comparateur de régime à hystérésis et assurant automatiquement la fermeture du volet pour permettre une alimentation minimum du mo ter en carburant. In order to remedy this and other disadvantages, the inventor has developed a device for controlling the solenoid valve by electronic means comprising a hysteresis speed comparator and automatically closing the flap for allow a minimum supply of fuel.

Le tableau synoptique ci-Joint est donné à titre d'illus- tr < tion.  The synoptic table attached is given as an illustration.

Selon l'invention les moyens électroniques sont logés yuans un bottier comportant - un premier étage 1 permettant de recevoir les informations
émises par un rupteur et de réaliser l'adaptation électro
nique des signaux-reçus, - ltn deuxième étage 2 est asservi à des cellules associées
permettant d'obtenir une tension électrique en relation
directe avec la fréquence des impulsions émises par le
rupteur, donc avec le régime moteur, - un comparateur de régime à hystérésis dont le fonctionnement
dépend du régime moteur et de la position de la pédale d'ac-
célérateur 5, - une commande de puissance ; transistor 4.
According to the invention, the electronic means are housed in a box comprising a first stage 1 for receiving the information.
emitted by a breaker and realize the electro adaptation
signals received, second-stage 2 is slaved to associated cells
to obtain an electrical voltage in relation
directly with the frequency of the pulses emitted by the
switch, therefore with the engine speed, - a hysteresis speed comparator whose operation
depends on the engine speed and the position of the
celerator 5, - a power control; transistor 4.

Le comparateur de régime a' hystérésis détermine une commutation dont la valeur est dépendante du réglage d'un potentiomètre, et le retour de commutation dépendant d'une résistance. The hysteresis speed comparator determines a switching whose value is dependent on the setting of a potentiometer, and the resistor dependent switching return.

Le dispositif est associé à un voyant lumineux du tableau de bord allumé lorsque l'éléctro-vanne est excitée, il reçoit des ordres émanant d'un contacteur dépendant pela pédale d'accélération, de telle manière que Si lecontacteur est fermé il se produit un ordre de masse (basculement prioritaire du comparateur 3)de façon que le couple de transistor n'autorise pas le passage du courant des électro-vannes.  The device is associated with a dashboard indicator light on when the electrovalve is excited, it receives orders from a contactor dependent pela accelerator pedal, so that If the contact is closed there occurs a order of mass (priority switching of the comparator 3) so that the transistor torque does not allow the passage of the current of the electro-valves.
