Abstract
Systems are provided for a cooling arrangement of an engine. In one example, a system includes a first coolant passage and a second coolant passage arranged in a cylinder bridge between directly adjacent cylinders, wherein the first coolant passage and the second coolant passage are separated from one another.
Claims20
An assembly, comprising:
- a cylinder head and a cylinder block of an internal combustion engine of a motor vehicle, wherein the cylinder head and the cylinder block jointly form two or more cylinders, which are at least partially cooled via coolant in a cooling jacket arranged in the cylinder block of the internal combustion engine, wherein the cylinders each comprise an upper region arranged in the cylinder head and a lower region situated below the upper region in the cylinder block;
- and
- a cylinder bridge arranged directly between two cylinders, wherein a first coolant channel is arranged in the upper region and a second coolant channel is arranged separately from the first coolant channel in the lower region.
An engine, comprising:
- a cylinder head and a cylinder block shaping a plurality of cylinders;
- a cylinder bridge is arranged between directly adjacent cylinders of the plurality of cylinders, wherein the cylinder bridge comprises a first coolant channel and a second coolant channel, wherein the first coolant channel extends from an upper region of the cylinder bridge to a coolant manifold, and wherein the second coolant channel extends from a lower region of the cylinder bridge to the coolant manifold.
An engine system, comprising:
- a cylinder head and a cylinder block shaping a plurality of cylinders;
- a cylinder bridge is arranged between directly adjacent cylinders of the plurality of cylinders, wherein the cylinder bridge comprises a first coolant channel and a second coolant channel, wherein the first coolant channel extends from an upper region of the cylinder bridge to a coolant manifold, and wherein the second coolant channel extend from a lower region of the cylinder bridge to the coolant manifold, and wherein a length of the first coolant channel is less than a length of the second coolant channel.
