Nox emissions reduction analysis in a diesel Euro VI Heavy Duty vehicle using a thermoelectric generator and an exhaust heater

Selective Catalytic Reduction systems (SCR) are very efficient on reducing NOx. However, they only perform properly when exhaust gas temperature is higher than 180 °C. This means that for low engine regimes combined with cold engine temperatures, SCR systems remains inactive. This study presents a n...

Experimental results show that NOx emissions can be reduced up to 80% when an EGH is added to a standard diesel-powered Euro VI Heavy Duty truck configuration. Apart from that, the use of an ATEG installed downstream of the aftertreatment system can produce the energy required by the EGH, which means that the EGH-ATEG system can work energetically autonomous and independent from the vehicle's electrical system.
