Abstract:
The present invention relates to an automatic nozzle for fuel economy suitable for all types of vehicles, which is mounted at the carburator and feeds, limits and stops the mixture or increases the air supply through the nozzle to the engine, when the diaphragm of the accelerator (18) of the carburator closes and braking of the car is performed. According to a preferable embodiment of the invention, the invented automatic nozzle is made, in turn of assembly, from a housing (1), a diaphragm or piston (2), a king-pin (3), a main body (4), a spring (5), a fitting part (6), a spring regulator or regulator for the displacement of the diaphragm or for the displacement of the needle (7), a nut (8) of the spring regulator, tightening nuts of the regulators (23) and (24), a clip-connector (9) of the needle, a needle (10), a nozzle (11), an underpressure speed member (12), a conductor (13), an electrical switch (16) and a control lamp (17). The automatic nozzle works using the suction of the engine supplied through the pipe (13), where one end of the said pipe is fitted at the suction (14) of the engine and the other end at the automatic nozzle, on the underpressure speed member (12). When the diaphragm (18) of the accelerator of the carburator is closed, the suction in the chamber of the automatic nozzle is increased, and forces the diaphragm (2) to move the king-pin (3) which is connected to the needle (10) and closes the hole (11 b), stopping the flow of the mixture (nozzle of Figure 1), or the opposite i.e. opens the hole (11b) allowing more air to stop the flow of mixture (nozzle of Figure 7). The said automatic nozzle may also operate electrically using an electromagnet (Figure 4).
Abstract:
To save fuel during engine deceleration, it has been proposed that the supply of fuel should be cut off. Such proposals have involved substantial redesign of the carburettor. The carburettor described comprises a throttle valve (14), an idling port (26) through which a fuel/air mixture is supplied on the down-stream side of the valve (14) when the latter is in a closed position, a channel (16) leading to the idling port and along which the fuel/air mixture is drawn, a longitudinally adjustable idle mixture adjusting device (27) having a tapered tip (38) projecting into the channel (16) and manually movable to move the tip (38) towards and away from the port (26) to set the idling mixture of the engine, and means operable through the idle mixture ajdusting device (27) for preventing the supply of fuel through the idling port during engine deceleration. The supply of fuel can be prevented by blocking the idling port (26) and/or by venting the region adjacent that port (26). Such a device (27) is simple to install and does not require significant redesign of a carburettor.
Abstract:
The process consist in effecting the carburated mixture in two phases: a premixture phase in a turbulence chamber (10) consisting in mixing the fuel flow C u with a make-up flow A u, small with respect to the idling airflow A u with a view to obtaining a highly carburated premixture, and a final mixture phase effected in a second chamber, said mixture chamber (5) consisting in mixing the premixture M u to the idling airflow A u. A needle (11) allows the adjustment of the flow of fuel in according to the engine running conditions.

Abstract:
An improved vacuum operated air valve for incorporation into the idle fuel port of an automotive carburetor. The valve includes a valve seat (20) having an inner conically-shaped area (26) and a surrounding planar area (25). The valve member (30) includes an axially oriented stem (31) and a flat radially-extending head (32), an outer end surface (35) of which overlies the valve seat surfaces (25 and 26), whereby opening the valve to a very minute axial displacement opens a substantial venting area, increasing the sensitivity of the valve.
Abstract:
Die Erfindung betrifft ein Verfahren zum Starten eines Verbrennungsmotors mit einem Seilzugstarter, wobei dem Verbrennungsmotor (14) über einen Ansaugkanal (20) ein Kraftstoff/Luft-Gemisch zugeführt ist. In dem Kraftstoffkanal (28) ist ein elektrisches Kraftstoffventil (30) angeordnet, das in seinem stromlosen Zustand offen ist und den Kraftstoffkanal (28) freigibt. Erst bei Anlegen einer Betriebsspannung (U) wird das Kraftstoffventil (30) schließen und den Kraftstoffkanal sperren, so dass in den Ansaugkanal (20) kein Kraftstoff angesaugt werden kann. Eine elektronische Steuereinheit (13) ist zur Ansteuerung des Kraftstoffventils (30) und zum Auslösen eines Zündfunkens an der Zündkerze (8) vorgesehen und wird von einem von der Kurbelwelle (6) angetriebenen Generator (9) zur Energieversorgung der elektrischen Verbraucher wie der Steuereinheit (13), des elektrischen Kraftstoffventils (30) und der Zündeinrichtung genutzt. Um ein Überfetten des Kraftstoff/Luft-Gemisches beim Start zu verhindern ist vorgesehen, die bei Beginn der Drehung der Kurbelwelle (6) erzeugte elektrische Energie zunächst zum Schließen des elektrischen Kraftstoffventils (30) zu verwenden, bevor die Steuereinheit (13) einen Zündfunken an der Zündkerze (8) auslöst.
Abstract:
Pour économiser du carburant pendant la décélération d'un moteur, il a été proposé de couper l'alimentation de carburant. De telles propositions ont entraîné des modifications substantielles de la conception du carburateur. Le carburateur décrit comprend un papillon-valve (14), un orifice de ralenti (26) au travers duquel un mélange carburant/air est envoyé côté aval du papillon-valve (14) lorsque ce dernier se trouve dans une position fermée, un canal (16) menant à l'orifice de ralenti et le long duquel le mélange carburant/air est aspiré, un dispositif de réglage du mélange de ralenti réglable longitudinalement (27) ayant une pointe conique (38) se projetant dans le canal (16) et mobile manuellement pour déplacer la pointe (38) vers et en retrait de l'orifice (26) pour régler le mélange de ralenti du moteur, et des moyens actionnables par l'intermédiaire du dispositif de réglage du mélange de ralenti (27) pour empêcher l'alimentation en carburant au travers de l'orifice de ralenti pendant la décélération du moteur. L'alimentation en carburant peut être empêchée en bloquant l'orifice de ralenti (26) et/ou en mettant à l'évent la région adjacente à cet orifice (26). Un tel dispositif (27) est simple à monter et ne demande aucune modification importante de la conception d'un carburateur.
