FIELD: engine devices and pumps.
SUBSTANCE: head of the cylinder block includes an upper surface, a surface (2) on the side of air intake, surface on the side of air discharge, front-end surface and rear end surface. On the upper surface there is a mounting base of a camshaft and a mounting boss (7) of a rocker bearing. A return oil channel (8) passes through the front and rear end surfaces. The head further comprises a first straight oil channel (10) extending vertically from the mounting boss (7) of the rocker bearing, and the second straight oil channel (11) extending horizontally from the surface from the side of air intake. A first forward and a second straight oil channels (10) and (11) communicate with each other. The second straight oil channel (11) communicates with the return oil channel (8). An engine with an upper camshaft and methods for manufacturing the head of cylinder head are disclosed.
EFFECT: size reduction and improvement of cylinder head and engine compactness.
