Abstract
(DE)
Es wird eine Brennkraftmaschine mit flüssigkeitsgekühlten Zylindern (1 bis 4) vorgeschlagen, bei der die Strömungsverteilung der in ringförmigen Kühlräumen (9 bis 12) verlaufenden Flüssigkeitsströmung gesteuert wird. Hierzu wird eine von der Fliessgeschwindigkeit der linken und rechten Strömungsanteile (15, 16) abhängige Grösse mittels Sensoren (18, 19) ermittelt und über einen Prozessor (P) eine im Anströmbereich befindliche Strömungsklappe (17) in ihrer Stellung entsprechend verändert.
(EN)
The invention relates to an internal combustion engine with liquid-cooled cylinders (1-4) in which the flow distribution of the liquid circulating in annular cooling spaces (9-12) is controlled. To this end a quantity depending on the flow speed of the left and right flow portions (15, 16) is determined by means of sensors (18, 19) and the position of a flow valve (17) arranged in the input flow area is modified correspondingly via a processor (P).
(FR)
L'invention concerne un moteur à combustion interne à cylindres (1 à 4) refroidis par liquide, dans lequel la répartition du débit de liquide s'écoulant dans des espaces de refroidissement (9 à 12) annulaires est régulée. A cet effet, une valeur dépendant de la vitesse d'écoulement des sections d'écoulement gauches et droites (15,16) est déterminée à l'aide de détecteurs (18,19) et la position d'un volet d'écoulement (17) situé dans la zone d'afflux est modifiée en conséquence.
