Improvements to the lubrication of the seats of a camshaft and a rocker-arm shaft in an internal combustion engine

Abstract

The invention relates to improvements that essentially comprise a novel arrangement of the lubricant lines that start at a deep transverse bore made in the cylinder head of the engine, characterised in that the lubricating oil line follows a path that reaches, via a first front line, each seat of the camshaft, with a second rear line starting at said seat and connecting to each seat of the rocker-arm shaft.

Description

technical field [0001] As this specification states in its title, the present invention relates to improvements in the lubrication of camshaft and rocker shaft mounts in internal combustion engines, and is intended to provide better lubrication to such camshaft and rocker shaft mounts. And effective grease lubrication. [0002] For this purpose, the improvements focus on the new arrangement of the lubricating lines, which extend from deep transverse openings positioned in the cylinder head, so that the novelty of the invention centers on the passages in which the lubricating oil route follows, the lubricating oil route Each camshaft base is first reached via a first front line, and a second rear line flowing into the rocker shaft base extends from the camshaft base. Background technique [0003] Lubrication of the camshaft base and the rocker shaft base in internal combustion engines is currently performed by driving pressurized oil through an internal circuit using a pump ...

AI Technical Summary

Problems solved by technology

[0005] In conventional lubrication systems, at special moments where the engine is subjected to high stresses requiring high power, the oil flow rate into the camshaft base and rocker shaft base may not be sufficient and thus may cause problems in the smooth action of engine components
