assembly line, supported by experienced technical engineers
and supporting resources in the industry, is equipped with core assembly
equipment (including high-precision bolt tightening machine, automatic
pressing machine, and automatic gluing machine) and test equipment such
as a comprehensive engine test bench. Before assembly, the cylinder body,
cylinder cover, and crankshaft have been ultrasonically cleaned to ensure
the cleanliness of the assembly effectively. During assembly, an accurate
group measurement was carried out for each component. Two groups of moving
components of the same set have been grouped again to achieve uniform weight
and dimensional tolerance, improve the movement smoothness of the components,
protect the moving components and their surrounding accessories from being
damaged, reduce the power loss/failure rate, prolong the overall service
life and improve the production efficiency.
