Title (EN) DEVICES AND METHODS TO AN INTERNAL COMBUSTION ENGINE AND A DEVICE FOR THERMAL INSULATION INTENDED TO BE USED THEREWITH
(FR) DISPOSITIFS ET PROCEDE SE RAPPORTANT A UN MOTEUR A COMBUSTION INTERNE ET MOYENS D'ISOLATION THERMIQUE UTILES DANS CE PROCEDE
Abstract:
(EN) Devices and methods in an internal combustion engine with a cooling system (2, 4, 5, 7) and a lubricating system (17, 19, 22) and a control unit (51). A thermal insulated accumulator tank (14) for storing heated coolant communicates via valve means (7, 10) with the coolant pump (2). The accumulator tank is built together with a pressure container (34) for storing heated engine oil. A drain pump (28) transfers all the oil from the oil sump (19) to the pressure container (34) when the engine is shut off, and the lubricating oil passages (22) are drained with the aid of the valves (24, 27). When re-starting, the oil is directed directly into the engine lubricating oil passages (22) via a valve (36) and cold coolant is replaced by warm coolant from the accumulator tank (14) with the aid of the valve (10). The double walled cover of the accumulator tank (14) comprises a high-vacuum zone (53) containing reflecting radiation barriers (74) of aluminum foil with space giving protuberances (75). The engine exhaust pipe (40) has a loop (48) emanating there from, with a controlled valve (47), which extends into the oil sump (19) for preheating the oil by means of the exhaust.
(FR) On décrit des dispositifs et procédés destinés à un moteur à combustion interne présentant un système de refroidissement (2, 4, 5, 7), un système de lubrification (17, 19, 22) ainsi qu'une unité de régulation (51). Un réservoir thermique isolé (14), destiné à emmagasiner le caloporteur chauffé, communique au moyen d'une soupape (7, 10) avec la pompe (2) à caloporteur. Ce réservoir est construction avec un récipient sous pression (34) servant à stocker l'huile chauffée du moteur. Une pompe de vidange (28) transfère toute l'huile du carter à huile (19) dans le récipient sous pression (34) lorsque le moteur est éteint, et les conduites (22) d'huile lubrifiante sont vidangées au moyen de soupapes (24, 27). Lors du redémarrage du moteur, l'huile est dirigée directement dans les conduites (22) d'huile du moteur, au moyen d'une soupape (36), et le caloporteur froid est remplacé par le caloporteur chaud provenant du réservoir(14), au moyen de la soupape (10). L'enveloppe à double paroi du réservoir (14) comprend une zone à vide poussé (53) contenant des barrières (74), en feuille d'aluminium, réfléchissant le rayonnement et présentant des protubérances (75) servant à former un espace entre elles. Le tuyau d'échappement (40) du moteur comporte une boucle (48) partant de celui-ci, pourvue d'une soupape commandée (47) et s'étendant dans le carter à huile (19), afin de préchauffer l'huile au moyen des gaz d'échappement chauds.
