overview








how we test the welder generator

Improve the lift of the camshaft, determine the trajectory curve, and better analyze the state of the fuel injection pump and fuel injector.
camshaft test

Ensure that the gas tightness of the cylinder head meets the requirements and improves the performance stability of the generator.
cylinder head test

The oil central processor, all oil must be filtered and then used, reducing the wear of the parts.
oil quality testing

Make sure that all data indicators of the cylinder are normal and can meet the assembly requirements of the engine.
cylinder test

Crankcase has a oil leakage test to ensure that there is no oil leakage problem.
crankcase seal test

Ensure bearing sealing and no oil leakage
bearing seal test

Makes the surface of spare parts smoother and reduces wear.
honing parts

Correct the axis offset, skew, and other defects of the processed hole to ensure the position accuracy of the hole, while also obtaining the required hole diameter tolerance and surface roughness.
precision boring process

Make sure the connection between the cylinder head and the box is firm and there is no possibility of air or water leakage.
torque test

Make sure the engine is running normally and stably without any abnormal noise.
engine test
