With a closed egr more nox will build up inside your engine if i understand corectly from varius website,s.(due to lower inlet temp or something)
But less exhaust gas wil dilute the engine with a closed egr .
Now what is the best option for a healthy engine ? blocked or open for hot dirty exhaust gas that lowers nox inside the engine ?
