Cooling circuit for a multi-cylinder internal combustion engine

摘要

The invention relates to a cooling circuit arrangement for a multicylinder internal combustion engine with V-shaped cylinder banks and cooling jackets (16, 18, 20, 22), which surround the cylinder banks and which are provided with cooling liquid by means of a pump, arranged between the two cylinder banks on one of their face sides. It is proposed that the pressure-sided connection (30) of the coolant pump, arranged on the one face side of the two cylinder banks, be connected by means of a coolant pipe (32) to a distributor pipe (34), arranged on the other face side of the cylinder banks, for the purpose of feeding cooling liquid; and that a return flow chamber (28, 56) for the coolant from the cooling jackets (16, 18, 20, 22) be arranged between the two cylinder banks adjacent to the pump housing (26). In this manner the space, existing between the two cylinder banks, is utilized for a part of the coolant arrangement so that the internal combustion engine exhibits a compact design.
