Two-cylinder diesel engine auxiliary starting decompressor

Abstract

The invention relates to a two-cylinder diesel engine auxiliary starting decompressor which comprises a decompression handle, a return torsional spring, a decompression connecting shaft, a supporting sleeve, valve rocker arms, a valve rocker arm shaft, a decompression shaft, a valve rocker arm support and the like. The valve rocker arm support is fixedly connected to a cylinder head through a bolt. The valve rocker arm shaft is fixed into a shaft hole of the valve rocker arm support through support top threads. The decompression shaft is sleeved with a hanging lug through hole of the valve rocker arm support. Decompression adjusting screws are arranged on two threaded holes of the decompression shaft and correspond to the longitudinal position of the first valve rocker arm and the longitudinal position of the third valve rocker arm respectively, and are locked through nuts. The ends of the decompression adjusting screw correspondingly abut against the rear end of the long arm spherical face contact of the first valve rocker arm and the rear end of the long arm spherical face contact of the third valve rocker arm. A flat groove of one end of the decompression shaft is connected with a tail key of the decompression connecting shaft. The two-cylinder diesel engine auxiliary starting decompressor is simple in structure; a user only needs to additionally arrange a decompression control device on a cylinder head cover and add the decompression shaft and the decompression adjusting screw on the rocker arm parts.

Description

technical field [0001] The invention relates to an auxiliary starting device for a two-cylinder diesel engine, in particular to an auxiliary starting decompression device for a two-cylinder diesel engine. Background technique [0002] Currently used two-cylinder, in-line, water-cooled, four-stroke, and large-bore diesel engines require too much power when starting due to excessive resistance, which seriously damages the starter motor. Especially in harsh weather conditions, such as the northern cold regions or plateau low-pressure areas, diesel engines often fail to start, which seriously affects the normal operation of diesel engines. Contents of the invention [0003] Aiming at the deficiencies in the above existing conditions, the present invention provides an auxiliary starting decompression device for a two-cylinder diesel engine. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A two-cylinder diesel engi...
