For the cleaning of modern diesel engines, car manufacturers rely on SCR catalytic converters to reduce nitrogen oxide (NOx) emissions. For this purpose, an aqueous urea solution is injected.
When driving mainly short distances and under difficult driving conditions, the required high temperatures in the exhaust system are often not achieved. The result: The conversion to nitrogen (N2) and water (H2O) cannot be carried out in the best possible way. As a result, white crystalline deposits form in the urea dosing system and in the SCR/SCRF catalytic converter, the reduction of NOx does not work properly, and increased emission values are achieved. The result can be engine malfunctions and loss of performance.
Tunap's 987 can help as it prevents the formation of crystals and cleans the already existing layers of crystals. With regular use, engine malfunctions are prevented and power losses due to clogging of the SCR catalytic converter are effectively reduced.
