Embodiment Construction

[0023] Hereinafter, an exemplary embodiment according to the inventive concept will be described in detail with reference to the accompanying drawings.

[0024] In an exemplary embodiment of the present invention, a cylinder head integrally formed with an exhaust manifold cools the exhaust manifold through an exhaust manifold water jacket extending on the exhaust side. Since the coolant flows mainly to the exhaust manifold, the cooling efficiency near the combustion chamber (exhaust port or spark plug hole) is reduced.

[0025] Therefore, the coolant needs to flow to the exhaust manifold towards the exhaust port or near the spark plug hole.

[0026] figure 1 is a view illustrating one side of an exhaust manifold-integrated cylinder head having a water jacket according to an exemplary embodiment of the inventive concept. figure 2 is along figure 1 A sectional view of the cylinder head taken along the line I-I in . image 3 is a perspective view of a head water jacket forme...

Abstract

An exhaust manifold integrally formed cylinder head with a water jacket includes an intake port through which external air is supplied and an exhaust port through which exhaust gas is discharged from a combustion chamber. The intake valve hole and the exhaust valve hole open the intake port and the exhaust port. Spark plug holes are formed on the top side of the cylinder head. A head water jacket is formed within the cylinder head to allow coolant to flow from one end to the other. The cover water jacket includes exhaust port bridging coolant passages formed between the exhaust ports. A lower coolant guide protrudes within the cylinder head so that coolant flows upward from the underside of the cylinder head through the exhaust port bridging coolant passages.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2014-0166791 filed with the Korean Intellectual Property Office on Nov. 26, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a cylinder head integrally formed with an exhaust manifold having a water jacket, which has a cooling structure capable of improving knocking characteristics and combustion characteristics by reducing temperatures near an exhaust port and a spark plug. Background technique [0004] The cylinder block and cylinder head of a vehicle engine have a water jacket to cool the heat generated in the combustion chamber and other mechanically operating components for the engine to prevent overheating. This water jacket also maintains the proper temperature of the engine for optimum thermal efficiency. [0005] That is, this water jacket allows coolant to pass ...
