AI Technical Summary
The external piping system of the existing rocker arm housing of internal combustion engines is prone to damage, has leakage points, and may interfere with other components, resulting in high assembly complexity.
A rocker arm housing is designed, comprising side walls and a top wall, an internal passage and a fuel return channel, reducing the need for an external piping system. The side walls and top wall are made of cast metal, and the internal passage is integrally formed between the side walls and the top wall, providing fluid communication between the fuel injector and the fuel return channel, and is sealed using an overflow pipe and a plug.
It reduces fuel leak paths, lowers component count and assembly complexity, improves accessibility to engine components, adapts to changes in fuel injector location, and reduces the number of fluid connections to be removed and installed.
