Abstract

The invention provides a horizontal intake and exhaust gas distribution device, which belongs to the field of engine gas distribution mechanisms. It solves the problem that the existing arrangement of intake and exhaust valves is difficult to meet the combustion experiment. It consists of intake cams and exhaust cams mounted on the camshaft, the intake cams and exhaust cams are in contact with the intake cam follower and exhaust cam follower respectively, the intake cam follower and the exhaust cam The bottom of the follower is connected to the driven shaft in rotation, the upper part of the intake cam follower is connected to the bottom of the intake rocker arm through the intake push rod, and the middle part of the intake rocker arm is connected to the intake rocker shaft. The upper part of the rocker arm is connected with the intake valve, and the upper part of the exhaust cam follower is connected with the bottom of the exhaust rocker arm through the exhaust push rod. The intake valve and the exhaust valve are horizontally arranged perpendicular to the piston running direction. The arrangement is located below the cylinder head and above the top dead center of the piston. It is mainly used for gas distribution of the engine.

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...
