• Multi pass piston ring seal: Combined with gas ring and oil ring, the cylinder has strong air tightness, reducing gas leakage and oil leakage, and improving combustion efficiency
• High temperature and deformation resistance: Both the cylinder sleeve and piston undergo high-temperature heat treatment to adapt to high load conditions inside the cylinder, and long-term operation will not deform or expand the cylinder
• High adaptability universal specifications: compatible with mainstream engine models of two-stroke/four stroke lawn mowers, replacing the original assembly without pressure
• Low fuel consumption power optimization: high assembly fit, precise cylinder compression ratio, full combustion of fuel, reducing fuel consumption while improving power
• Lightweight forged piston: fast heat dissipation, light weight, reducing crankshaft operating load
