Internal combustion engine cooling circuit, has upper cylinder head water chamber connected upstream from cooling pump whose outlet is connected to lower cylinder head water chamber, to prevent coolant from circulating in radiator

摘要

The circuit has a cylinder head water chamber with a lower cylinder head water chamber (3) and an upper cylinder head water chamber (3). The chamber (3) is connected upstream from a cooling pump (1) placed upstream of an internal combustion engine to ensure coolant circulation. An outlet (10) of the pump is connected to the chamber (3) in which the coolant circulates, to prevent coolant from circulating in a radiator (5).
