An engine and a method of forming an engine are provided. The engine has a block that defines a cooling jacket extending continuously about an outer perimeter of first and second siamesed cylinders. The block defines a series of head bolt bores intersecting a deck face such that each cylinder is surrounded by four bores. The jacket has a first floor and a second floor. The second floor is offset above the first floor and extends along an intake side of the block between midpoints of the first and second cylinders, respectively. The second floor is configured to decouple a relationship between the cooling jacket and the series of bores for each cylinder and reduce fourth order bore distortion for each cylinder.

Cylinder block for internal combustion engine

An engine includes a cylinder block with first and second saw cuts intersecting a block face on opposed sides of a block bore bridge. A cylinder head has third and fourth saw cuts intersecting a head face on opposed sides of a head bore bridge. A gasket is placed between the block and the head. The gasket defines a cooling passage adapted to fluidly connect the first, second, third and fourth saw cuts and cool the interbore region of the engine. The cooling passage has an inlet and a pair of outlets.

Bore bridge and cylinder cooling

An engine includes a cylinder block having first and second passages intersecting a block face on opposed sides of a bore bridge defining a bore bridge cooling passage. A cylinder head has third and fourth passages intersecting a head face. The first and fourth passages are opposed from one another. A gasket is placed between the block and the head. The gasket adapted to fluidly connect the first and fourth passages via the bore bridge cooling passage, and cover the second passage.
