Working principle of Variable Valve Actuation(VVA) technology

Working principle of Variable Valve Actuation(VVA) technology
- VVA technology has two different cam size for intake valves only and the exhaust remains constant.
-In normal condition ,when the engine revolution is less than 7400 rpm the smaller cam  works but there is no any work of larger cam in this condition.
-Now when the engine revolution is increased more than 7400 rpm ,the larger cam  works ,the sensors detects the revolution and the motor operates so that the pin is inserted to connect the valve to larger cam.
-when larger cam works ,means that the more air-fuel mixture enters to the engine and the engine can produce more power due to more combustion of fuels.
Thanks!
