A. Crank case. Gravity casting aluminium alloy makes the crank case stand at perfect strength and excellent stiffness. 

B. Plunger: Stainless steel plunger and bushes coating provide the maximum resisitance to corrosion and abrasion. 

C. Connecting rod: Special zinc, magnesium alloy starts the highest tensile and wear-proof characteristic of the connecting rods. 

D. Crank shaft: The shrome-molybdenum steel crank shaft guaranees the best tensile strength and surface hardness for long time operation. 

E. Cylinder: Stainless mainfolds totally corrosion-resistance and with reliable bearing strength.
