Abstract:
Liquid-cooled internal combustion V engine with cylinder banks which tilt toward one another, comprising:a cylinder crankcase having a crankcase housing and a pair of cylinder banks configured in a V-shape to form a V space therebetween, a pair of cylinder heads assigned separately to each of the cylinder banks, external exhaust gas-sided cooling jackets and internal cooling jackets separated by cylinder pipes in each of the cylinder banks, a coolant inflow line extending between the cylinder banks in the V space and crankcase housing end-sided distribution channels operable to feed coolant to the respective external exhaust gas-sided cooling jackets, cross throughflow channels formed in the respective cylinder heads operable to guide coolant flow from the respective exhaust gas-sided cooling jackets to the internal coolant jackets which border the V space, an outflow line which is formed by crankcase housing end-sided cross walls and a separate cover, and throttle openings in cylinder bank boundaries in a bottom segment of the V space connecting the internal coolant jackets with the outflow line, wherein the inflow line is a separate line from the outflow line and is arranged imperviously in break-throughs of the cross walls, wherein the outflow line is connectable to a coolant pump by an outflow connection arranged in the V-space, and wherein the inflow line is connectable to a coolant pump by an inflow connection arranged in the V-space.
