Abstract
A cylinder head for a water-cooled, multi-cylinder piston internal combustion engine comprises a lower wall and an upper wall enclosing a cavity. A well extends into the cavity for receiving a fuel injector and/or an ignition device. An intake port and/or an exhaust port extends through the cavity. A cooling-water carrying region comprises areas of the cavity surrounding the well, intake port, and exhaust port. Portions of the cooling-water carrying region are provided with an intermediate web for reinforcing the cylinder head.
Claims16
A cylinder head for a water-cooled, multi-cylinder piston internal combustion engine, the cylinder head comprising:
- a lower wall and an upper wall enclosing a cavity;
- a well extending into the cavity for receiving at least one of a fuel injector or an ignition device;
- an intake port extending through the cavity;
- an exhaust port extending through the cavity;
- and
- a cooling-water carrying region comprising areas of the cavity surrounding the well, intake port, and exhaust port, wherein portions of the cooling-water carrying region are provided with an intermediate web for reinforcing the cylinder head.
The cylinder head of claim 7, wherein the reinforcing rib transitions into the intermediate web.
A cylinder head for a water cooled, multi-cylinder piston internal combustion engine, comprising:
- an upper wall;
- a lower wall opposite the upper wall;
- a cooling-water carrying region bound by the upper wall and the lower wall;
- an intake port projecting from the lower wall into the cooling-water carrying region;
- an exhaust port projecting from the lower wall into the cooling-water carrying region;
- and
- an intermediate web for reinforcing the cylinder head;
- wherein the intermediate web is substantially planar and divides the cooling-water carrying region into an upper region and a lower region, and the intermediate web allows for exchange between cooling water flowing through the upper region and cooling water flowing through the lower region.
