Problems solved by technology

However, the former structure uses plastic casting, and due to the gap corresponding to the casting tolerance, the flow of cooling water is scattered, which reduces the cooling efficiency, while the latter structure requires additional separate cooling when applying an integral flow control valve valve, which complicates the structure of the one-piece valve and increases its size

Abstract

The present disclosure provides a split cooling apparatus for an internal combustion engine, the apparatus including: a base inserted into a water jacket of a cylinder block, the base surrounding an outside of a cylinder along a shape of the cylinder; an insertion groove formed on the base by being depressed into an inner surface of the base; and a sealing member inserted into the insertion groove, wherein when a temperature of cooling water supplied into the water jacket reaches a preset temperature or higher, the sealing member expands so as to close a flow passage between the base and the cylinder, thereby increasing flow resistance of the cooling water and thus reducing a heat transfer rate of the cylinder.

Description

technical field [0001] The present disclosure relates generally to a cooling arrangement for an internal combustion engine, and more particularly, to a separate cooling arrangement for an internal combustion engine. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In general, conventional vehicles employ a siamese-type cylinder block in a multi-cylinder engine with a short distance between cylinders (bore pitch) for reducing The purpose of the size, weight and overall length of a multi-cylinder engine. Since the one-piece cylinder block has no water jacket (cooling water passage) between the cylinder liners and it is formed by casting a plurality of cylinder liners using aluminum in order to join them to each other, the one-piece cylinder block is configured as a cylinder core Short distance. [0004] Since the one-piece cylinder block has a short...
