Abstract
An engine cooling system for a vehicle may relate for flowing the coolant from the front side to the rear side based on an arrangement direction of the cylinder and simultaneously cooling the coolant by a cross flow type to flow from an exhaust side to an intake side between each combustion chambers while separating and cooling the coolant flowing through the cylinder block and the cylinder head, maximizing an entire cooling efficiency through a flow control of the coolant and reducing a fuel consumption.
Claims17
An engine cooling system for a vehicle in which a plurality of combustion chambers is formed from a front side to a rear side of an engine and for cooling the engine including a cylinder block to which a cylinder head is mounted upwards thereof, the engine cooling system comprising:
- a head water jacket formed inside the cylinder head;
- a block water jacket formed around the combustion chambers inside the cylinder block;
- a gasket disposed between the block water jacket and the head water jacket and sealing between the cylinder block and the cylinder head;
- a pump water jacket connected to the block water jacket inside the cylinder block by corresponding to a water pump mounted on a front side of the cylinder block to pump a coolant to a front side of the block water jacket;
- first and second connection passages formed at a front upper portion of the block water jacket, connected to a front lower portion of the head water jacket, and supplying the coolant supplied to the block water jacket to the head water jacket;
- a first packing member mounted on an intake side in the front side of the block water jacket and preventing the coolant flowing to the front side of the block water jacket from inflowing to the intake side;
- and
- a second packing member mounted on an exhaust side in a rear side of the block water jacket and limiting a flow rate of the coolant flowing along the exhaust side of the block water jacket,
- wherein the block water jacket further includes:
- a third connection passage formed toward the second connection passage based on the first packing member;
- and
- a fourth connection passage formed on the intake side at the rear side of the block water jacket based on the first packing member, and
- wherein a cross-section of the third connection passage is formed to be greater than a cross-section of the fourth connection passage.
The engine cooling system for the vehicle of claim wherein the gasket includes:
- a first penetration hole at a position corresponding to the first connection passage;
- a second penetration hole at a position corresponding to the second connection passage;
- a third penetration hole at a position corresponding to the third connection passage;
- and
- a fourth penetration hole at a position corresponding to the fourth connection passage.
