* Combine the strong points of 2 stroke and 4 stroke engine light weight, strong power,easy maintainance,low noise, low emission,cost efficiency high
* Cancel the lubricating system,save the cost and weight.
* Employ the fuel of gas/oil mixture, don't need to check oil everyday.
* Simplified structure bring compact architecture,easy maintainance.
* Low emission, cancle the catalyst. So the engine will not be over heating as 2 stroke engine
