  • Patent number: 10808595
    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.

  • Publication number: 20170058753
    Abstract: An engine system includes a cylinder block and a cylinder head. A coolant control valve unit is engaged with the cylinder head to receive a coolant exhausted from the cylinder block and a coolant exhausted from the cylinder head. The coolant control valve unit controls a coolant to be supplied to a heater, a radiator, and an oil cooler and controls the coolant exhausted from the cylinder block. The coolant control valve unit receives the coolant from the cylinder head, supplies the coolant to the oil cooler, and controls the coolant distributed to the heater and the coolant exhausted from the cylinder block.
