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.

Cooled Exhaust Gas Recirculation (EGR)
Precise amounts of cooled exhaust gases are mixed with incoming fresh air lowering combustion temperatures. This improves performance and lowers emissions.
Efficient exhaust gas recirculation (EGR)
The 48V e4Boost solution, composed of an Electric Supercharger 48V and a Belt Starter Generator iBSG 48V, recovers a maximum amount of braking energy and stores it in a 48V battery.
