(FR) MOTEUR À COMBUSTION INTERNE
(DE) BRENNKRAFTMASCHINE MIT HARNSTOFFWASSERLÖSUNGSEINSPRITZUNG IM ABGASSTRANG
Abstract:
(EN) The invention relates to an internal combustion engine comprising an aqueous urea injection solution in the exhaust tract, comprising at least one aqueous urea solution tank, at least one pump, at least one suction line leading to the pump, at least one aqueous urea solution metering valve which is connected to the pump, and at least one return flow line which leads from the pump to the aqueous urea solution tank and a filter element which is arranged on the end opposite the pump, and at least one aqueous urea solution sensor which is arranged in the aqueous urea solution tank.
(FR) La présente invention concerne un moteur à combustion interne doté d'une injection de solution aqueuse d'urée dans la conduite de gaz d'échappement, comprenant au moins un réservoir de solution aqueuse d'urée, au moins une pompe, au moins une conduite d'aspiration menant à la pompe, au moins une vanne doseuse de solution aqueuse d'urée reliée à la pompe au moyen d'une conduite de pression, et au moins une conduite de reflux allant de la pompe au réservoir de solution aqueuse d'urée et à l'extrémité de laquelle située à l'opposé de la pompe est disposé un élément filtrant, ainsi qu'au moins un capteur de solution aqueuse d'urée disposé dans le réservoir de solution aqueuse d'urée.
(DE) Brennkraftmaschine mit Harnstoffwasserlösungseinspritzung im Abgasstrang, umfassend wenigstens einen Harnstoffwasserlösungstank, wenigstens eine Pumpe, wenigstens eine zur Pumpe führende Ansaugleitung, wenigstens ein Harnstoffwasserlösungsdosierventil, das mittels einer Druckleitung mit der Pumpe verbunden ist und wenigstens eine Rückflussleitung, die von der Pumpe zum Harnstoffwasserlösungstank führt und an deren der Pumpe entgegengesetztem Ende ein Filterelement angeordnet ist, sowie wenigstens ein im Harnstoffwasserlösungstank angeordneter Harnstoffwasserlösungssensor.
