From the Facts About Scr Site
Diesel Exhaust Fluid is subject to freezing at the lowest temperatures. For example, Diesel Exhaust Fluid (made up of a 32.5% urea solution) may freeze at temperatures at or below 12° F. Although this temperature is encountered in colder climates during the winter season, it has not proven to be a problem for SCR-equipped trucks. Freezing does not impact its functionality and Diesel Exhaust Fluid is easily thawed within moments by the warmth of the engine.
Some automotive-grade urea producers are working on non-freezing additives and technologies. In the meantime, equipment systems are being developed and will be used to ensure that Diesel Exhaust Fluid thaws quickly. In fact, the EPA sees no problem in allowing it to reheat in the morning using the warmth of the engine when the truck is started. |
This sounds good, and I've been wondering about how these new smaller diesels will do in the cold. Does anyone know if these have glow-plugs or other strategies for starting in the cold? While I have a heated garage at home, here in northern MN my vehicle often has to spend 8-10 hrs in sub-zero temps throughout the day.
