Abstract:
A cylinder head cooling structure includes: an intake-side cooling passage, inter-cylinder cooling passages, inter-port cooling passages, first cooling water supply passages that include an upstream end connected to a cooling water supply passage provided in a cylinder block of the engine and a downstream end which joins an upstream end of the inter-cylinder cooling passage; and blocking walls that are provided in the inter-cylinder cooling passages and extend obliquely in a direction from the exhaust ports of the cylinder on an upstream side to the intake ports of the cylinder on a downstream side to divide the inter-cylinder cooling passage.

Claim (Index 1):
A cylinder head cooling structure in which a plurality of cylinders are disposed in series in a longitudinal direction of an engine, a pair of exhaust ports and a pair of intake ports are disposed opposite to each other in the cylinder, and an injector is installed between the intake ports opposite to the exhaust ports, the cooling structure comprising:\n an intake-side cooling passage that extends along an intake side of the cylinder head in the longitudinal direction of the engine; a plurality of inter-cylinder cooling passages that extend between the cylinders in a transverse direction of the engine and include a downstream end which joins the intake-side cooling passage; a plurality of inter-port cooling passages that include an upstream end branching from one inter-cylinder cooling passage, extend between the exhaust port and the intake port in the longitudinal direction of the engine, and include a downstream end which joins another inter-cylinder cooling passage; a plurality of first cooling water supply passages that include an upstream end connected to a cooling water supply passage provided in a cylinder block of the engine and a downstream end which joins the upstream end of the inter-cylinder cooling passage; and a blocking walls that is provided in the inter-cylinder cooling passages and extend obliquely in a direction from the exhaust ports of the cylinder on an upstream side to the intake ports of the cylinder on a downstream side to divide the inter-cylinder cooling passage.
