Title (EN) INTERNAL COMBUSTION ENGINE AND METHOD
(FR) MOTEUR À COMBUSTION INTERNE ET PROCÉDÉ
(DE) BRENNKRAFTMASCHINE UND VERFAHREN
Abstract:
(EN) The invention relates to an internal combustion engine (1), in particular a reciprocating-piston internal combustion engine, comprising a camshaft (3) and an oil spray cooling device (15), which is designed to produce oil spray jets (A) for cooling at least one piston (7) of the internal combustion engine (1), wherein the internal combustion engine (1) is designed to mechanically control, by means of the camshaft (3), the generation of oil spray jets by the oil spray cooling device (15). The invention further relates to a method to be carried out by means of the internal combustion engine.
(FR) L'invention concerne un moteur à combustion interne (1), en particulier un moteur à combustion interne à pistons alternatifs, lequel comprend un arbre à cames (3) et un dispositif de refroidissement par aspersion d'huile (15), lequel est conçu de manière à produire des jets d'aspersion d'huile (A) pour le refroidissement d'au moins un piston (7) du moteur à combustion interne (1), ledit moteur à combustion interne (1) étant conçu de manière à piloter la production de jets d'aspersion d'huile via le dispositif de refroidissement par aspersion d'huile (15) mécaniquement par l'intermédiaire de l'arbre à cames (3). L'invention concerne également un procédé associé à mettre en oeuvre avec le moteur à combustion interne.
(DE) Brennkraftmaschine (1), insbesondere Hubkolben-Brennkraftmaschine, mit einer Nockenwelle (3) und einer Ölspritzkühleinrichtung (15), welche eingerichtet ist, Ölspritzstrahlen (A) für die Kühlung wenigstens eines Kolbens (7) der Brennkraftmaschine (1) zu erzeugen, wobei die Brennkraftmaschine (1) eingerichtet ist, die Ölspritzstrahlerzeugung via die Ölspritzkühleinrichtung (15) mechanisch über die Nockenwelle (3) zu steuern. Einher geht hiermit ein Verfahren zur Ausführung mit der Brennkraftmaschine.
