LC-automobile strong speedup gasoline economizer is developed according to the aerodynamic principium, it makes the air current entering the device produce rotating impulse swirling, the flow speed accelerates, the air quality is enhanced, the oxygen density in the air content improves, therefore, can reach optimum hollow burning ratio; The foggy degree of the gasoline improves, thus, provides the best environment and condition for gasoline to burn completely within a certain period of time.
