Abstract

An engine system having a coolant control valve may include a cylinder block, a cylinder head, an exhaust gas recirculation (EGR) cooler, a heater core, an oil cooler or a radiator and a coolant control valve. The cylinder block is configured with cylinders; the cylinder head is sitting on top of the cylinder block and comprises exhaust ports and intake ports configured to lead to the cylinders, the Exhaust Gas Recirculation (EGR) cooler, the heater core, the oil cooler, or the radiator through which coolant circulates, and the coolant control valve configured to control a coolant supplied to the cylinder block, a coolant discharged from the cylinder block through the cylinder head, and a coolant supplied to the EGR cooler, the heater core, the oil cooler, or the radiator.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0160899 filed on Nov. 18, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an engine system having a coolant control valve capable of improving overall cooling efficiency and reducing fuel consumption by controlling both coolant supply to a cylinder block and coolant discharge from a cylinder head. Background technique [0004] The engine produces power by burning fuel to generate torque and expel excess heat. Specifically, as the coolant circulates through the engine, heater, and radiator, the coolant absorbs heat energy and releases heat energy. [0005] The viscosity of the oil becomes higher at low engine coolant temperatures. The use of thicker oil increases friction and fuel consumption, and the exhaust gas temperature gradually increases,...
