AdBlue® and damage to SCR catalytic converters
Year of publication: 2024
AdBlue® is the technical prerequisite for operating modern diesel engines with exhaust gas after-treatment systems. However, if the AdBlue® used is “contaminated” or “unclean”, it can become a serious hazard to the SCR catalytic converters (selective catalytic reduction). In the OELCHECK laboratory, high-precision analysis is therefore not only used to check AdBlue® quality, but can also help in the event of problems or even damage to SCR catalytic converters related to the use of urea solution. The values determined in the laboratory clearly indicate the causes. And it is becoming increasingly clear: In many cases, the specifications for the correct use of the urea solution have not been observed!
