Rumors Fly Regarding Next-Gen Cummins

Long-Hauler engine II
We’re starting to hear some rumblings about the next-generation Cummins turbo-diesel engine — which makes up about 85 percent of all Ram HD sales — being slated for installation in 2014 models. 

Another hurdle in emissions regulations is due for the 2014 model year, and we hear that Cummins may move away from its relatively expensive precious-metal catalyst strategy in favor of the proven  urea-injection technology. (Ram HDs don't need to use urea-injection fluid tanks, whereas Ford's Power Stroke and GM's Duramax engines use urea injection.)

Because of a different EPA regulation for commercial chassis-cab trucks, the Ram 3500, 4500 and 5500 work trucks already use diesel exhaust fluid to neutralize nitrous oxide emissions, while the catalytic-converter-like filters of the non-commercial Ram 2500 HD and Ram 3500 HD are used elsewhere, and the costs of those catalysts are climbing.

That makes the possibility of steering toward the less-expensive industry-standard DEF more likely. The only real question, especially since Ram already has the technology on other HDs, is why wouldn’t they start putting the new urea-injection technology on all Ram HDs starting Jan. 1, 2013, to be the first to meet the stricter emissions regulations?

That would make sense to us, but then again we haven’t heard anything definitive yet. 


The problem I see with DEF is it has to Ber refilled a lot! As a heavy duty tech I know from experience. Peterbilts have been using it for about 3 years now and drivers are always stopping in and buying cases of 5 gal jugs. It drives the cost of a service up due to the light duty trucks have it refilled every service interval. And if you actually use the truck like its built for in towing or ag applications you will be buying more def too due to high idle times and lots of usage. Me personally the government has no business telling car manufacturers how to build and tune vehicles, I mean seriously look at the way they run the rest of the country.

If indeed Cumins come up with the disel engine without need of urea, I will BE definatley buying 4 dodge n trash thinking about ford or gm. I do NOT mind at all pay extra n I do NOT need 2 worry about ONE another thing that I am driving in highway n ran out of urea, etc!
