Passive regeneration/CRT effect (Continuous Regeneration Trap)
MTU uses the CRT effect for regenerating the diesel particulate filter. This is based on chemical reactions that take place in the engine’s exhaust aftertreatment system. First of all, nitrogen dioxide (NO2) is produced in the oxidation catalyst from the nitrogen monoxide (NO) in the ex-haust gas. In the diesel particulate filter, the process is reversed and the soot deposited in the diesel particulate filter is continuously burned off. Hence the name “Continuous Regeneration Trap” (CRT), i.e. a continuously regenerating filter. This effect is also referred to as passive regeneration. In contrast to active regeneration, the reaction requires no additional energy.

Turbocharger with variable turbine geometry (VTG)
With variable turbine geometry, the power delivery and response characteristics of the turbo-charger can be better adapted to the dynamic engine operating conditions. The exhaust passes over adjustable guides to the turbine blades so that the turbine spools up quickly at low engine speeds and subsequently allows high exhaust gas flow rates.
