Technical characteristics
副标题
■ Optimize transmission system
The main and auxiliary shaft gears with large modulus are adopted to increase the gear strength and improve the reliability of engine torque output.

■ Optimize electric starting system
Increase the modulus and thickness of the gear, improve the strength of the gear, and use a special overrunning clutch to improve the reliability of the electric starting system.

■ Optimize cooling system
Increase the volume of the water channel, increase the speed of the water pump, increase the water volume and lift of the pump, and meet various requirements for the use of tricycles.

■ Optimize clutch mechanism
Spring damping, steel gear and widened friction plate are adopted to improve the bearing capacity of the clutch, which is durable and non-slip.

■ Double wear-resistant piston ring technology
Double DLC technology piston ring, centrifugal cylinder liner and cylinder block combination, improve wear resistance by 50%, effectively prevent oil burning.

■ Solution technology valve
The secondary solid solution exhaust valve is adopted to effectively prevent valve fracture.

Multi-layer sealing technology
Between the high-precision cylinder head and the cylinder block, the multi-layer sealing gasket with new structure is used to effectively avoid water and oil leakage.

■ Multistage filtration technology
The use of a new crankshaft filter structure significantly reduces crankshaft failure.

■ Massive oil storage technology

Large oil pan crankcase structure, increase the pump oil volume by 50%, effectively reduce the engine temperature and ensure good lubrication of all parts.
