Our product portfolio includes numerous technologies which result in significant emission reduction, particularly when several systems are interacting. These technologies include engine management systems, transmission control units, injection systems, hybrid drives and their associated sensors and actuators. In addition, we offer innovative exhaust gas aftertreatment technologies, including exhaust fuel injectors for an improved regeneration strategy and SCR systems for selective catalytic reduction for passenger car applications. SCR technology (Selective Catalytic Reduction) functions, by injecting an aqueous urea solution into the diesel exhaust stream. This chemical process within a dedicated SCR catalytic converter leads to a significant reduction of NOx emissions.  | | Control Unit for Exhaust Gas Aftertreatment |
The data from engine catalytic converter and environmental is collected by sensors and analyzed by the engine electronics which is the basis for calculating the optimum injection volume of aqueous urea solution.Our commercial vehicle controller solutions for diesel engine management optimize fuel efficiency, while simultaneously reducing emissions. They support future oriented exhaust gas aftertreatment concepts such as SCR and Diesel Particulate Filters (DPF) and are available both as engine control units and as control units for exhaust gas aftertreatment (SCR control units). The interaction between both technologies allows the fulfillment of today’s Euro IV and V emission legislation and enables the achievement of future emission limits (Euro VI, EPA10, JP09). For the control of Exhaust Gas Recirculation (EGR) rates, we have developed an on-site Engine Control Unit (ECU) that integrates the EGR valve and control algorithms in one EEGR control unit for this demanding, high temperature application.
