Embodiment Construction

[0031] combine figure 1 and figure 2 , The cylinder head has a top surface 1, an intake side 2 with intake ports distributed, an exhaust side 3 with exhaust ports distributed, a front end face 4 facing the timing train and a rear end face 5 opposite to the front end face 4. Those of ordinary skill in the art should understand that the top surface 1 is defined relative to the bottom surface (not marked) of the cylinder head in contact with the cylinder block (not shown), while the front end surface 4 and the rear end surface 5 are relative to the positions of the timing gear train Defined, of course, other definition methods can also be used. On the top surface 1, a camshaft mounting seat 6 is distributed, and a rocker arm support mounting boss 7 is distributed near it. The oil return passage 8 extends from the front end face 4 to the rear end face 5, thereby penetrating the entire cylinder head between the front end face and the rear end face, as a part of the cylinder lubr...

Abstract

The invention provides a cylinder head which comprises a top face, an air inlet side face, a exhaust side face, a front end face, and a rear end face. A camshaft mounting seat and a rocker support mounting boss are distributed on the top face. A through oil return passage is arranged between the front end face and the rear end face. The cylinder head is provided with a first straight oil hole vertically downwardly extending from the rocker support mounting boss and a second straight oil hole horizontally extending from the air inlet side face. The first straight oil hole is communicated with the second straight oil hole which is communicated with the oil return passage. The invention further provides an overhead camshaft engine with the cylinder head. By the cylinder head, the engine structure is compacter to further achieve miniaturization.

Description

technical field [0001] The invention relates to the field of engines, in particular to a cylinder head using a straight oil hole to supply oil to a valve rocker arm and an overhead camshaft engine using the cylinder head. Background technique [0002] In the development process of the automobile industry, how to realize the miniaturization and compactness of the engine has always been the goal pursued by the designers. [0003] In the invention patent of Chinese patent application number: 96192117.X, application date: 1996-10-16, and the invention name "rocker arm assembly of internal combustion engine", an internal combustion engine is disclosed, and the valve rocker arm is installed to the cylinder through the rocker arm support When installing the rocker arm support on the cylinder head and fastening it to the cylinder head, it is necessary to cast a rocker arm support installation boss on the cylinder head. Moreover, in order to provide lubrication to the valve rocker a...
