08 years ago, is the 4 thimble plate, or a mechanical linkage structure, large occupied space, lack of thrust, the effect is poor, the cost is expensive, difficult to maintain.

08 years later, the research and development of the first generation equipment gas turbocharger, pressure limited in the 400~600KG large volume, high cost, eager effect is very good, but the structure of the project investment is too high, maintenance difficulties, the application of the scope of.

After 12 years, the development of hydraulic supercharger, small volume, pressure reaches 800~1000KG passive volume can be greatly reduced, the passive volume reduced, increasing the application range, passive completely standardized, price advantage, application scope, maintenance time advantage, technology advantage to lower the threshold.
