Alright Guys,

I know that this isn't the truckers forum, but I got to get up close and personal with International's newest engine platform today and it was quite interesting. The Maxxforce 13 is a 410-475 hp big bore 4 cycle diesel that has excellent manners. It's a twin turbo (low load and high load engagement) with 4 valves/cylinder, EGR, DOC and DPF emissions components which hauls like a mofo. The 475 pulled the mountain foothills like nothing was there and was so quiet at idle that I thought it was a gasser.

Now for the oil porn...the sump is roughly 45 quarts and uses a cartridge style filtration set-up...pretty cool for class 8. API CJ-4 is specifieded with 25,000 mile OCI's. Fuel filtration follows suit with cartridge style injection. Running >5% biodiesel jeopardizes your warranty per international's prose. It's a common rail injection system with about a 25,000psi injector tip off. All and all it was pretty sweet and put the ISX to shame with it's street manners and ease of lubrication. The only drawback I see is the fact that finding a coolant or exhaust leak on this bad boy would take forever due to the snaking that each respectively takes around the engine compartment. We'll be measuring fuel economy over the next few months, but this is a good showing so far.
 
Good stuff!

Kinda leary on the maxxforce myself, especially since cummins just announced they're going SCR as well. That leaves international by itself. We all know what happened the last time a major engine maker did that....


Anyways, I do like the CGI block, the way they make the electronics, and the high pressure. Not a fan of the cooling system though.

BTW, detroits DD15 has 32,000 psi, and volvos are up to 36,000 psi now.
 
The cooling system definitely does leave a lot to be desired. I have a feeling that this platform will last a few seasons then end up being a one off found in fleets. It does look pretty wild to see this beast stuffed between the frame rails though! I didn't realize that the volvos were up that high...jeesh.
 
Last I heard is that Cummins will use SCR on medium duty but only more EGR on their HD engines for 2010.
