Now With Urea Injection And Nine InjectorsAutomotive manufacturing history includes two brutal horsepower wars. The first involved gasoline engines and started when the GI's returned home from WWII. It ended with the 1973 oil crisis. This oil embargo gave birth to the next slow-starting and fierce-ending feud, which we are all veterans of-the diesel horsepower wars. Notice how power levels have recently leveled off? It's because in 2010, manufacturers need to address what's coming out the tailpipe just as much as they have to worry about what numbers the engine makes. Since we're optimistic and believe the past is a guide, we predict we'll see the emissions restrictions turn into a catalyst for better performing diesel engines. Fortunately for us, a world without problems is a very boring place for engineers.

nine injectors instead of 8 wow how can you beat that

Duramax is doing some crazy things nine injectors oo boy wonder how annoying that will be to replace :jump:

I was wondering why they weren't using the exhaust fuel injection event like Cummins uses.

I don't know if I buy the "more precise setup" part, but I find the "Diesel in the oil" explanation intriguing. Have there been active-regen-related oil contamination problems that I have not been aware of?


The good news with the downpipe injector is that you can easily hijack it for a built-in flame thrower exhaust. :rock:

whats the mpg like on the new LML?

19mpg average predicted hwy, 15mpg city

I noticed there were no HP numbers...maybe nothing to brag about?? :w2: :pca1:

cant wait to see this at the chicago auto show on friday

how does the regeneration of DPF work is it more effective ?

the 9th injector is used for the regens, instead of dumping fuel into the cylinders it injects fuel directly in front of the dpf:tu:
