UpValve is a Variable Valve Actuation (VVA) system that allows continuously variable control of the valve lift between full travel and valve shut-off.
Smart Sound is a mechatronic system based on a loudspeaker actuator - capable of adjusting the powertrain acoustic performance on demand (cancellation and enhancement)
For hybrid vehicles, its EHRS are widely used to reduce engine warm-up times to improve fuel economy, reduce emissions and provide cabin heating.
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.
