Features: 1, patented engine with independent intellectual property rights, patent numbers: ZL03252828.0, ZL02332803.7, ZL02332800.
2. The optimized structure of the advanced balance gear makes the engine vibrate less, and the driving is more stable and safer;
3, the integral cylinder head, the camshaft hole is formed at one time, and the noise of the cylinder head is low; ?
4. The optimized combustion chamber accelerates the flame propagation speed in the combustion process, effectively prevents deflagration, and makes the piston heat transfer more uniform and the emission lower. ?
