Problems solved by technology

[0002] The 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

Embodiment

[0023] see figure 1 . A two-cylinder diesel engine auxiliary starting decompression device, comprising a decompression handle 1, a return torsion spring 2, a decompression connecting shaft 3, a support sleeve 4, a limit pin 5, a decompression control board 6, a cylinder head cover 7, a decompression Finale 8, valve rocker shaft support 10, valve rocker shaft 11 and valve rocker 9.

[0024] see Figure 6 . Its center of valve rocking arm 9 is provided with axle hole, and its short arm end is provided with threaded hole, and its long arm end is provided with spherical contact. see figure 1 , four valve rocker arms 9 shaft holes are sleeved on the valve rocker shaft 11 in turn, and its longitudinal arrangement spacing corresponds to the longitudinal arrangement spacing of the intake valves 17 on the cylinder head 12 . The two shaft ends of the valve rocker arm shaft 11 are clamped on the outer sides of the first and fourth valve rocker arms 9 arranged from left to right thro...

Abstract

The invention relates to an auxiliary starting decompression device for a two-cylinder diesel engine. Wait. The valve rocker arm support is fixedly connected to the cylinder head by bolts, the valve rocker arm shaft is fixed in the shaft hole of the valve rocker arm support through the support top screw, and the valve rocker arm support lug through hole is sleeved on the decompression shaft superior. Both threaded holes on the decompression shaft are provided with decompression adjustment screws respectively corresponding to the longitudinal positions of the first and third valve rocker arms, and are locked by nuts. The end of the decompression adjustment screw is correspondingly abutted against the rear end of the long arm spherical contact of the first and third valve rocker arms. The flat groove at the end of the decompression shaft is keyed to the rear end of the decompression shaft. The present invention is simple in structure, only needs to add the decompression control device on the cylinder head cover, add a decompression shaft and decompression adjustment screw on the rocker arm part.

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 engin...
