Major Performance and Characteristics
|
Low-speed and large-torque technology:
|
Increase the power and torque by above 20%, for better starting and accelerating performances and stronger power;
|
Crankshaft displacement technology:
|
Improve the engine power performance and reduce the noise effectively;
|
Roller valve rockerarm:
|
Reduce the friction of rockerarm and camshaft, improve the power performance and the durability of rockerarm and camshaft;
|
Dual channel cooling technique:
|
Improve the cylinder head cooling efficiency, with better strength than common structure, and reduce the noise of cylinder head effectively;
|
Built-in pressure reducing valve:
|
Decrease the electric/kick starting load effectively, and guarantee the integrity of engine appearance;
|
Piston sprinkling technique:
|
Increase the lubricating efficiency of relevant parts, such as piston and cylinder block, reduce the energy loss and improve the durability of parts and components;
|
Lightweight piston:
|
Decrease the inertial mass of piston movement by 20%, reduce the energy loss and vibration; and improve the comfort of complete vehicle;
|
Clutch optimization technique:
|
Use the main clutch of three-disc spring type for compact dimension, and use the friction plate of high quality formula for more stable power transmission and better comfortable riding;
|
Speed ratio optimization technique:
|
Optimize the speed ratio of every gear position, to ensure the starting, accelerating and maximum speed performances, and improve the riding comfort;
|
High-power DC power supply technique:
|
Use 12-pole full-wave DC magneto of 12V, to adequately satisfy the complete vehicle power consumption requirement of top-grade vehicle.
|
Overrunning clutch of new type:
|
Use six-roller overrunning clutch of new type for better bearing capacity;
|
Integral sealing technique:
|
The oil immersed integral sealing is applied to the left front cover, to thoroughly solve the oil leakage problem of traditional horizontal engine.
|
Triangle positioning suspension technology:
|
By use of the triangular stability, three-suspension design is applied, for better coordination between engine and complete vehicle and better vibration-proof effect.
