Eaton’s ORVR system is a vehicle emission control system that collects evaporative fuel vapors that emit during the refueling process and burn them during normal operation.

VTC (Valve Timing Control)
The compact integration of controller, motor, and pump enables application on various vehicles.
Optimized control of motor lowers the noise.
Product is available from 30W to 80W (input).
Flow is shut at engine start in order to quickly warm-up the engine.
Valve is designed to open by the force of cooling water flow so that the valve could stay open during power off (for fail safe).
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
