Internal combustion engine cooling device for vehicle, has coolant storage reservoir connected to hollow passages and to transport circuit, and with variable volume for storing coolant, where reservoir is thermally insulated at periphery

摘要

#CMT# #/CMT# The device (1) has an engine portion (2) in which hollow passages (3) are arranged, where the passage permits circulation of a coolant (4) in the portion. A transport circuit (5) transports external cooling fluid to a motor, and is connected to the passages. A coolant storage reservoir (6) is connected to the passages and to the circuit to store the coolant. The reservoir has a variable volume for storing the coolant, where the reservoir is thermally insulated at its periphery. #CMT#USE : #/CMT# Device for cooling an internal combustion engine of a vehicle. #CMT#ADVANTAGE : #/CMT# The coolant storage reservoir has variable volume for storing the coolant, thus permitting to adapt the storage volume of the reservoir to the quantity of the coolant stored in the reservoir, and hence permitting to reduce the volume of air contained in the reservoir so that the storage volume is always equal to the volume of stored coolant. The device permits to optimize the increase in temperature of the internal combustion engine, thus permitting to reduce fuel consumption and pollutant emission of the engine, while permitting to improve the thermal comfort of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of an internal combustion engine cooling device. 1 : Internal combustion engine cooling device 2 : Engine portion 3 : Hollow passages 4 : Coolant 5 : Transport circuit 6 : Coolant storage reservoir.
