Claims

[Scope of utility model registration request]

The cylinder head, which is superimposed on the cylinder block, is equipped with two valve drive camshafts and intake and exhaust side rocker arms that are swing-driven by the valve drive camshafts to open and close the intake and exhaust valves. DOH with a system valve train
In the C-type multi-cylinder internal combustion engine, the cylinder head has a main oil supply passage communicating with an oil supply passage on the cylinder block side in the longitudinal center thereof, and two oil supply passages extending parallel to each other in the longitudinal direction of the cylinder head. Oil gear and the above 2
Extends across the longitudinal center of the book's oil gear gallery,
A communicating oil passage is provided that communicates these oil gear larries with the main oil supply passage, and the two oil gear larches are connected to the lubricating surface of the bearing portion of the suction and exhaust valve drive camshafts and the swinging of the suction and exhaust rocker arms. A lubrication device for a valve mechanism in a DOHC multi-cylinder internal combustion engine, characterized in that the device communicates with a lubrication surface of a support.
