Problems solved by technology

However, for gasoline engines, the arrangement of intake and exhaust valves on the cylinder head has limitations, and the use of oblique valves will increase the arrangement range of the valves, and at the same time, affect the arrangement of other components (such as carburetor / air filter and other parts) ; Especially for the vertical shaft gasoline engine with the lower camshaft, the use of oblique valves will affect the arrangement of the pushrod and the camshaft

Abstract

Disclosed are a vertical-shaft gasoline engine cylinder head assembly and a gasoline engine having same, comprising a cylinder head body (1), an intake passage (12) disposed on said cylinder head body (1), and an exhaust passage (11) disposed on said cylinder head body (1). An intake valve (5) corresponding to the intake passage (12) is provided on the cylinder head body (1). An exhaust valve (9) corresponding to the exhaust passage (11) is provided on the cylinder head body (1). An intake rocker arm (8) and an intake push rod are provided corresponding to the intake valve (5). An exhaust rocker arm (2) and exhaust push rod are provided corresponding to the exhaust valve (9). A line connecting the axis of the intake valve and the axis of the exhaust valve and a line connecting the axis of the intake push rod and the axis of the exhaust push rod intersect between the axis of the intake push rod and the axis of the exhaust push rod.

Description

technical field [0001] The invention relates to a power machine component and its application, in particular to a gasoline engine component and its application. Background technique [0002] A gasoline engine is a power machine that uses gasoline as fuel. It is composed of a cylinder, a crank linkage mechanism, a gas distribution system, an oil supply system, a lubrication system, and an ignition system; the cylinder head is provided with an intake port and an exhaust port, and forms a combustion chamber surface together with the cylinder, so it belongs to a gasoline engine. more important parts. Gasoline is burned as a mixture of fuel and air in the combustion chamber to generate a large amount of heat, which is used as driving energy. [0003] The gas distribution system of the gasoline engine is a necessary part to ensure the normal operation of the gasoline engine. It generally includes the intake valve and the exhaust valve on the cylinder head. The components are co...
