FEATURES & ADVANTAGES
3.Generation Piston
The new body is optimized in structure design, with a novel appearance and high structural strength, improved durability with cylinder bore hardening process.
The new cylinder head is optimized in structure design, reducing exhaust pulses andlowering operating noise.
The new valve plate is optimized in structure design, improving exhaust efficiencyand enhancing shock resistance.
The new motor is optimized in structure design, improving operational efficiency,increasing overload capacity,and expanding the operating range.
The new bearing is optimized in structure design, increasing lubrication effectivenessand reducing the risk of shaft seizure.
The new piston optimizes the piston structure and reduces the clearance volume..Thinner piston ring design reduces friction loss.
