By controlling the oil flow rate under any engine running conditions, additional work is reduced, which then contributes to the reduction of engine friction losses.
With its CVO (Controlled Valve Operation) system solution for direct injection engines, Bosch has adopted a mechatronic approach that can make a valuable contribution to legal limits for emissions. Unlike conventional open-loop controlled injection, the control unit and high-pressure injectors constitute a closed loop in this setup. The control unit detects the triggering signal for the high-pressure injectors across the entire injection process and determines the timing for opening and closing the valve needles. Thus, the control unit can calculate the actual injection quantities of each injector and make adjustments where necessary. CVO offers an innovative and cost-effective approach to engine optimization.
The compact integration of controller, motor, and pump enables application on various vehicles.
Optimized control of motor lowers the noise.
Product is available from low capacity (for assisting hydraulic pressure of VVT) to high capacity (for hydraulic assist of CVT and AT).
