Bore bridge cooling channels

A system, comprising:

• a cylinder block with a first cylinder and a second cylinder adjacent to the first cylinder and a bore bridge positioned between the first cylinder and the second cylinder, the cylinder block further including a coolant jacket at least partially surrounding the first cylinder and the second cylinder;
• and
• a set of cooling passages positioned within the bore bridge, the set of cooling passages including a first cooling passage having a first inlet fluidly coupled to the coolant jacket and a second cooling passage having a second inlet fluidly coupled to the coolant jacket, vertically above the first inlet, each of the first cooling passage and the second cooling passage terminating at a common outlet positioned at a deck face of the cylinder block, the first cooling passage extending from the first inlet to the common outlet in a substantially straight line and the second cooling passage including a first portion extending from the second inlet to an apex of the second cooling passage and a second portion extending from the apex to the common outlet.
