MWM cylinder liner process improvement

2022-10-10

 DEUTZ-MWM TBD234 cylinder liner is a cylinder liner suitable for diesel engines, generators and marine engines. The cylinder liner is an important wear-resistant part in the engine block. The life of the cylinder liner will directly affect the engine life. At present, the most widely used type of cylinder liner is metal cylinder liner, most of which are thin-walled. Due to the wear of piston rings and erosion of corrosive media, the cylinder liner is prone to failures such as strain, groove, peeling, leakage, de-cylinder and rupture.
 
According to the various factors that actually exist in the cylinder liner, find countermeasures on the "passivity". Appropriate adjustments have been made to the material of the cylinder liner to adapt to different use environments and users, and a new inlaid "carbon scraping ring" protection technology has been added to reduce the damage of carbon deposits on the cylinder liner; improve the machining accuracy and reduce the negative impact of components. The "platform reticulation" of the working stroke surface reduces the running-in period; through the above methods and technological improvements, the service life of the cylinder liner is increased by 1 to 2 times or more, and the oil consumption is greatly reduced and stable.
