Answers

#SensorFAQs – Q6 1/8 | Yes – But first of all, let’s explain what an SCR System is.

An SCR (Selective Catalytic Reduction) system is a system installed on diesel vehicles 🚗 to reduce harmful Nitrous Oxide (NOx) emissions. It works by injecting an automotive grade urea… https://t.co/LiylSpuPLN

#SensorFAQs – Q6 2/8 | …or DEF through a specially designed catalyst, into the exhaust stream of a diesel engine.

The DEF sets off a chemical reaction which converts the NOx into Nitrogen, water and very small amounts of CO2. Up to 90% NOx reduction can be achieved. https://t.co/LiylSpuPLN
