Abstract
An engine has a cylinder block with first and second cylinders separated by a bore bridge. The block has a cooling jacket with a cooling channel intersecting a block deck face and circumferentially surrounding the first and second cylinders such that the engine block has an open deck configuration. The engine has a cylinder head with a surface configured to mate with the deck face of the block. The surface of the head has a sleeve protruding therefrom. The sleeve is sized to be received by the channel to circumferentially surround the first and second cylinders to structurally support the cylinders.
Claims20
An engine comprising:
- a cylinder block having first and second cylinders separated by a bore bridge, and a block cooling jacket having a channel intersecting a block deck face to circumferentially surround the first and second cylinders;
- and
- a cylinder head having a surface configured to mate with the deck face, the surface having a sleeve protruding therefrom and sized to be received by the channel to circumferentially surround the first and second cylinders.
An engine comprising:
- a cylinder block defining a cooling channel circumferentially surrounding an outer wall of at least one cylinder, the cooling channel intersecting a deck face;
- and
- a cylinder head having a surface configured to mate with the deck face, the surface having at least one projection extending outwardly therefrom, the at least one projection received by the channel to cooperate with the outer wall and structurally support the at least one cylinder.
A method of forming an engine comprising:
- forming a block with cast-in passages for a cooling jacket and first and second adjoined cylinders having an outer wall, the cooling jacket circumferentially surrounding the outer wall and intersecting a block deck face;
- forming a cylinder head with at least one projection extending outwardly from an intermediate region of a head deck face, the head deck face configured to cooperate with the block deck face;
- and
- assembling the cylinder head and the block such that the at least one projection is received within the cooling jacket to surround and cooperate with the outer wall of the first and second cylinders to structurally support the first and second cylinders.
