Abstract
Methods and systems are provided for mounting a fuel pump to a cylinder head of an engine. In one example, a mounting system may comprise: an engine fuel pump mounted directly to a cylinder head cap positioned underneath a cam cover, the cap including a raised portion having a first and a second cap mounting boss, and a main opening for directly receiving the fuel pump, wherein each of the first and second cap mounting bosses couple to a flange formed on a bottom portion of the fuel pump. In this way, the fuel pump may be directly mounted to the cylinder head cap to simplify assembly, minimize fuel leakage and reduce pump vibration.
Claims15
An engine comprising:
- a cylinder head;
- a cover mounted to a top of the cylinder head;
- a cap coupled to the cylinder head and having an annular top portion, a curved middle portion, and a c-shaped lower portion, wherein the curved middle portion includes an outer surface having a recessed slot designed to receive a sealing gasket;
- and
- a fuel pump mounted directly to the cap and covered by the cover.
An engine comprising:
- a cylinder head;
- a cover mounted to a top of the cylinder head, wherein the cover includes a recessed groove and a plurality of compression tabs, wherein each compression tab of the plurality of compression tabs has a height controlling compression of a press-in-place gasket mounted to the recessed groove;
- a cap coupled to the cylinder head and having an annular top portion, a curved middle portion, and a c-shaped lower portion;
- and
- a fuel pump mounted directly to the cap and covered by the cover.
