Abstract

The invention provides a transverse air intake and exhaust distribution device, belongs to the field of engine air distribution mechanisms, and solves the problem that an existing air intake and exhaust valve arrangement mode is difficult to meet the combustion experiment. An air intake cam and an air outlet cam are installed on a cam shaft, the air intake cam and the air outlet cam make contact with an air intake cam driven piece and an air outlet cam driven piece respectively, the bottom end of the air intake cam driven piece and the bottom end of the air outlet cam driven piece are both rotationally connected with a driven shaft, the upper part of the air intake cam driven piece is connected with the bottom of an air intake rocker arm through an air intake push rod, the middle of the air intake rocker arm is connected with an air intake rocker arm shaft, the upper part of the air intake rocker arm is connected with an air intake valve, the upper part of the air outlet cam driven piece is connected with the bottom of an air outlet rocker arm through an air outlet push rod, an air intake valve and an exhaust valve are transversely arranged in the mode of being perpendicular to the running direction of a piston, and the arrangement positions are located below a cylinder cover and are higher than the top dead center of the piston. The device is mainly used for engine air distribution.

Description

technical field [0001] The invention belongs to the field of engine gas distribution mechanisms, in particular to a horizontal intake and exhaust gas distribution device. Background technique [0002] In the prior art, the engine crankshaft and the camshaft are connected by timing gears, so that the rotation of the crankshaft is synchronized with the camshaft, and the camshaft controls the opening or closing of the intake and exhaust valves by controlling mechanisms such as push rods and rocker arms. The existing valve train basically adopts overhead valve train. When the test needs to install multiple fuel injectors or glass windows on the top of the cylinder head, if the overhead valve train is used, it is not enough to arrange enough fuel injectors to simulate the combustion process of the required test, and it is not enough to arrange a large enough fuel injector. The top visualization window is used to observe the combustion process in the combustion chamber, which doe...
