DISPOSITIF DE RECHAUFFEMENT DU
CARBURANT COMPORTANT UN MOYEN
DE CHAUFFAGE ELECTRIQUE
La présente invention concerne un dispositif de réchauffement du carburant pour moteur a combustion interne comportant un moyen de chauffage électrique.DEVICE FOR HEATING THE
FUEL COMPRISING A MEANS
ELECTRIC HEATER
The present invention relates to a fuel heating device for an internal combustion engine comprising an electric heating means.
Des dispositifs utilisant des moyens électriques sont déjà connus de l'art antérieur mais ils présentent plusieurs inconvénients. Devices using electrical means are already known from the prior art, but they have several drawbacks.
Par exemple, leur mise en oeuvre est délicate et nécessite l'adjonction au moteur d'une chambre de chauffage ou d'un tuyau de chauffage, ou bien l'échauffement du carburant n'est pas situé à l'endroit optimum sur le trajet de carburant. For example, their implementation is delicate and requires the addition to the engine of a heating chamber or a heating pipe, or the heating of the fuel is not located at the optimum location on the route. fuel.
Le dispositif conforme à l'invention se propose de palier tous les inconvénients de l'art antérieur. The device according to the invention proposes to overcome all the drawbacks of the prior art.
Conformément à l'invention le moyen chauffant électrique est en contact direct avec au moins une partie de la paroi externe de chaque gicleur du mo-teur à combustion interne. In accordance with the invention, the electric heating means is in direct contact with at least part of the external wall of each nozzle of the internal combustion engine.
On comprendra mieux l'invention à l'aide de la description ci-après faite en référence à la figure unique annexée. The invention will be better understood using the description below made with reference to the attached single figure.
La figure annexée représente une coupe partielle d'un carburateur pour moteur à combustion interne faisant apparaitre le gicleur conforme à l'invention. The attached figure shows a partial section of a carburetor for an internal combustion engine showing the nozzle according to the invention.
Le dispositif de réchauffement comporte un moyen de chauffage électrique (1) enveloppant directement la surface extérieure du conduit d'injection d'un gicleur (2). The heating device comprises an electric heating means (1) directly enveloping the external surface of the injection pipe of a nozzle (2).
Le moyen chauffant (I) peut être par exemple une résistance électrique, convenablement isolée électriquement, bobinée ou enroulée, à la périphérie du gicleur, ou encore une résistance électrique noyée ou maintenue dans tout moyen de support, une gaine par -exemple. The heating means (I) can be for example an electrical resistance, suitably electrically insulated, wound or wound, at the periphery of the nozzle, or an electrical resistance embedded or held in any support means, a sheath for example.
Le carburant est ainsi chauffé en aval de la pompe à essence (4) et avant de pénétrer dans la zone d'admission (3) des cylindres jusqu'à une température optimale prédéterminée permettant une vaporisation totale de l'essence lors du mélange air-carburant. The fuel is thus heated downstream of the petrol pump (4) and before entering the intake zone (3) of the cylinders to a predetermined optimum temperature allowing total vaporization of the petrol during the air-mixture. fuel.
Avantageusement la résistance électrique utilisée peut etre tarée ou commandée par un thermostat dans le cas où l'on veut obtenir une température régulière. Advantageously, the electrical resistance used can be calibrated or controlled by a thermostat in the case where it is desired to obtain a regular temperature.
Des logements non représentés sont prévus pour le passage des fils conducteurs reliant le moyen électrique (I) à une source de courant pouvant par exemple etre la batterie du véhicule ou toute autre source de courant. Housing (not shown) is provided for the passage of the conducting wires connecting the electrical means (I) to a current source which may, for example, be the vehicle battery or any other current source.
Le dispositif conforme à l'invention peut fonctionner sur un moteur à combustion normale ou à turbocompression. The device according to the invention can operate on a normal combustion or turbocharged engine.
En outre, puisque la vaporisation du carburant est complète grâce au dispositif conforme à l'invention, la consommation de carburant diminue à puissance égale, et la souplesse du moteur ainsi que les performances sont améliorées. In addition, since the fuel vaporization is complete thanks to the device according to the invention, the fuel consumption decreases at equal power, and the flexibility of the engine as well as the performances are improved.
Enfin le dispositif de réchauffement de carburant peut être utilisé pour tout type de carburant. Finally, the fuel heating device can be used for any type of fuel.
