Cummins is saying 1.5% urea to diesel ratio for light duty diesels.

That means 1.5gal of Eureka for every 100gallons of diesel burned.

As mentioned, HD trucks won't need it because they run loaded most of the time, they produce far less NOx because they operate at a richer average fuel ratio.

Here's what Cummins is doing for the future:

All the Dodge Ram and lighter duty diesels will have urea after 1 Jan 2010, just like the early vs late 2007 CTDs had different emissions components.

Hohn, source on this? From what I read they are saying the specific 6.7 in the Ram meets all 2010 specs, and should not change. They do say other lines will have to use SCR.

 

Good catch. You are correct. Gee, I'm asleep at the switch. Ram will NOT use urea.

Sorry

There are MD diesels switching to urea in 2010, but the Ram is not one of them.

 

HOHN,

Thanks for the link. It was good reading.
