The lightweight piston is adopted to reduce the inertia of piston up and down motion and improve engine vibration; Adding oil storage tank to improve piston lubrication and molybdenum disulfide treatment of skirt did not improve piston service life；

Six springs, six columns and BM103 friction plate are used to make the separation and combination more stable and wear-resistant, and the service life is greatly increased；  

The front built-in balance structure is used to set the balance shaft to balance the first order inertia force generated by the engine, reduce the vibration caused by the reciprocating motion of the crankshaft, and improve the stability and comfort of the whole vehicle；

The special crankshaft can enlarge the stroke and improve the engine power and torque; The crankshaft bearing and box adopt the hot installation process to effectively reduce the noise of running crankshaft and ensure smooth operation；

Adopt KU fine needle roller to improve engine reliability; The crankshaft bearing and box adopt the hot installation process to effectively reduce the noise of running crankshaft and ensure smooth operation；

The cylinder block adopts platform reticulation technology to make the formation of oil film easier. The lubrication between cylinder block, piston and piston ring is improved, and the reliability is improved；

DLC piston ring is adopted to improve engine service life； 

Luba second-generation cylinder block is adopted to effectively reduce cylinder head noise。
