Definitions
- the invention relates to a speed controller for internal combustion engines according to the preamble of claim 1.
- the actuator 31 is designed as a temperature-controlled expansion element and has, on the end, resting on the base support 26, a plunger 47 which transmits the vertical actuating movement of the actuator 31.
Abstract
Dans des régulateurs centrifuges de tous régimes qui commandent en fonction de la pression d'admission la pleine charge de la pompe correspondante d'injection de carburant, il faut réduire l'admission de démarrage à des températures élevées de fonctionnement du moteur à combusion interne afin d'éviter l'émission soudaine de fumée lors du démarrage à chaud. A cet effet, le régulateur de régime comprend outre un support de base (26) un support supplémentaire (28). Le support supplémentaire (28) est monté rotatif sur le support de base (26) et peut pivoter entre deux butées de régulation (31, 32). Outre une butée de pleine charge (27) située sur le support de base (26), le support supplémentaire (28) comprend une butée supplémentaire (33) déplacée transversalement au sens de rotation du support de base (26) en fonction de la pression d'admission par une unité d'adaptation (41). La butée de régulation (31) forme un organe de régulation (31) à commande thermique qui place la butée supplémentaire (33) de sorte qu'un organe capteur (39) dont la position est déterminante pour le dosage de carburant pousse la butée supplémentaire (33) hors de la zone de détection de l'organe capteur (39) à des températures réduites de fonctionnement du moteur à combustion interne, ce qui permet d'admettre les doses élevées requises de carburant, alors qu'en cas de démarrage à chaud, la butée supplémentaire (33) pénètre dans la zone de détection de l'organe capteur (39), limitant les doses de carburant et empêchant l'émission soudaine de fumée lors du démarrage à chaud.In centrifugal regulators of all speeds which control the full load of the corresponding fuel injection pump as a function of the intake pressure, it is necessary to reduce the starting intake at high operating temperatures of the internal combustion engine in order to avoid the sudden emission of smoke during hot starting. For this purpose, the speed regulator comprises, in addition to a base support (26), an additional support (28). The additional support (28) is rotatably mounted on the base support (26) and can pivot between two regulating stops (31, 32). In addition to a full load stop (27) located on the base support (26), the additional support (28) comprises an additional stop (33) moved transversely to the direction of rotation of the base support (26) depending on the pressure admission by an adaptation unit (41). The regulating stop (31) forms a thermally controlled regulating member (31) which places the additional stop (33) in such a way that a sensor member (39) whose position is decisive for the fuel metering pushes the additional stop (33) outside the detection zone of the sensor member (39) at reduced operating temperatures of the internal combustion engine, which makes it possible to admit the required high doses of fuel, whereas in the event of starting at hot, the additional stop (33) enters the detection zone of the sensor member (39), limiting the doses of fuel and preventing the sudden emission of smoke during hot starting.
