Problems solved by technology

[0005] Aiming at the technical problem that it is laborious to start the engine by kick starting in the prior art, and it is difficult to start the engine running, the present invention provides a decompression mechanism for manually starting the motorcycle engine. The ejector rod is set, and the movement of the ejector rod is controlled by the manipulating shaft to realize the partial opening of the exhaust valve, thereby reducing the resistance of the compressed mixed gas during the upward movement of the piston

Abstract

A manual start decompression mechanism for a motorcycle engine comprises a body and a spring holder connected with the same. An operating shaft is disposed on the body. An ejector bar device is disposed inside the spring holder. The operating shaft controls an exhaust valve to open or close through the ejector bar device. The decompression mechanism is disposed at the exhaust valve, so that the engine can be decompressed during starting; the decompression mechanism has few parts and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a decompression device for a motorcycle engine, in particular to a decompression mechanism for manual starting of the motorcycle engine. Background technique [0002] When the motorcycle engine is in the starting stage, external force is needed to provide the starting speed required for the normal operation of the engine. This external force needs to overcome the resistance of the piston to compress the mixed gas, the elastic force of the valve spring, and the friction between the moving parts. The resistance of compressing the mixed gas is determined by the compression ratio and displacement of the engine. There are two ways of providing external force: electric starting and foot starting. Normally, the motorcycle engine provides external force by means of electric starting to drive the crankshaft to start the engine. When the electric starting method cannot work normally, in order to ensure that the motorcycle can start nor...
