The head micro-arc oxidation is adopted to achieve heat insulation effect, improve the service life of the piston and improve the engine cylinder pulling problem (CG125/CG150/CG200);
The piston is lightweight, reducing the weight of the piston, effectively reducing the unbalance of the crank inertia force during the piston operation, and improving the engine vibration (CG250);
Thin piston rings are used to reduce friction with the cylinder block, improve mechanical efficiency loss and improve engine performance (CG250);
Six springs and six columns are used to make the clutch combination more stable and wear-resistant, and the service life is greatly increased (CG125/CG150);
Six springs, six columns and thickened teeth are used to make the disengagement more stable and wear-resistant, and greatly increase its service life (CG200/CG250);
Adopt KU fine needle roller to improve engine reliability (CG150);
With KU fine needle roller and enlarged crankshaft bearing, the bearing capacity is stronger and the engine reliability is improved; Crankshaft and case are hot-pressed to reduce engine noise（CG200）；
KU fine needle roller and thickened bearing are adopted to enhance bearing capacity and improve engine reliability; The crankshaft and case are hot-pressed to reduce engine noise (CG250);
The engine reliability is improved by using integral push rod (CG250);
Silent cylinder head is adopted to effectively reduce cylinder head noise (CG150);
Luba second-generation cylinder head is adopted to effectively reduce cylinder head noise (CG150);
The platform screen technology is adopted to make the formation of oil film easier. The lubrication between cylinder block, piston and piston ring is improved, and the reliability is improved (CG125/CG150/CG200/CG250);
Imported steel mattresses are used to reduce large deformation and ablation of thermal engine steel beds, improve engine noise and reliability (CG125/CG150/CG200/CG250)
The use of chilled alloy cast iron improves wear resistance and significantly increases service life (CG125); The special labyrinth box can improve the balance of exhaust gas pressure, prevent fuel injection from exhaust pipe and reduce oil consumption (CG250).
