Abstract

System for cooling a motor vehicle engine comprising a crankcase (10), a cylinder head (12) containing the passages and seats of the intake valves and exhaust valves, said system comprising a pump (24) and a heat-transfer fluid circuit which branches downstream of the pump (24) in order to separately supply a bottom chamber (14, 18) for cooling the crankcase (10) and that part of the cylinder head surrounding the intake valves, and a top chamber (16) for cooling that part of the cylinder head surrounding the exhaust valves, the two branches of the heat-transfer fluid circuit converging at the outlet of the top and bottom chambers. The invention also relates to a diesel engine comprising such a cooling system.
