International Prosatar/Maxxforce: Worthless junk!!!

I think its mostly about performance. Why waste fuel: its a double whammy right? EGR starves the engine of oxygen a bit to lower the combustion temperature to reduce the amount of NOx generated. That makes soot, which takes fuel to clean out the DPF...

Now as for the acid part... Lets look at Cetane (you know of the Cetane number? - That number on the side of the Diesel pump). It has the chemical formula of C16H34. If we open up the high school chemistry book, if you burn it you get...

2C16H34 + 49O2 -> 32CO2 + 34H2O

Now air is 78% nitrogen right? So if you get the combustion temperature of diesel up high enough and it starts to "burn" (oxidize) the nitrogen in the air creating the infamous NOx

Well lets see....

If you mix NOx with water you get nitric acid (sometimes called the strongest acid in chemistry). So EGR has a little bit of nitric acid in it...

So yeah the more EGR run, the more nitric acid you're trying to push through your cylinders. Of course it should only cause a problem when you shut off the engine and it condenses in your intake and EGR cooler...

 

None taken. This post has nothing to do with the Prostar replacing the 9200. I liked and still like the 9200-9400(I-series too).

 

CO2 regulation is a scam. Clean air isn't. Making sure a Diesel puts out just CO2 & H2O that is a worthy goal. Jacking up diesel prices with stupid regulation is bad. Now if the truck manufacturers could think about investing enough time and money in ensuring a good system... For them after-treatment means after-thought.

Think about the automobiles of today. They essentially have zero emissions (because CO2 is NOT a pollutant) with the best reliability they've ever had. It took them 20 years to get there though and all of us had to suffer though the waste that was the 80s & 90s.

Now if we could get the power industry lobby out of the ### of our politicians we could get power plants that ran at something above 30% efficiency and didn't spew mercury, NOx and assorted toxins and heavy metals into the air. Ever seen the cars of the power plant workers? Not a spot of paint on them...

 

My experience with 2 prostars has been the complete opposite of the original poster. Ive got 160K on a 09 Prostar, The ride is like no other truck Ive ever been in. Its such a pleasure to drive I ordered another. The 2010 with 09 motor (DPF) has 40K miles and haven't had any problems with either truck. Both have the Cummins ISX's in them 500 & 's 600 HP. With the emissions and DPF'S they dont run like the older motors but the way it maneuvers, drives, and rides is very impressive.

 

That's just too funny right there! Funnier because it's true! It's in an awkward and uncomfortable position for me.

This is too funny. I have my old Freightliner down for a clutch and some other time consuming small tedious crap. I rented a ProStar. I had rented one a while back when they first came out and didn't really like it. It was BRAND NEW, though. The one I rented last night has about 300,000 miles on it. After driving it, I know that wouldn't trade my old '96 Freightliner for two of those pieces of crap!

The mirrors shake and rattle so bad that they are utterly useless. It has ZERO foot/leg room. It has a door that's about a foot thick and yet still leaks more air and makes more noise than my old FLD doors. The whole truck rocks back and forth violently and the front end is a wreck. It has more wind noise than my old FLD. IN fact, I think it would be quieter sitting OUT ON THE HOOD of my FLD. I HATE all those controls on the steering wheel. I'll NEVER buy a truck with all of that crap on the wheel. I blinked my trailer lights and honked the horn all night trying to find the jakes. Yup, air horn in the steering wheel. Totally retarded. Don't be surprised when you momentarily turn off your headlights trying to set the cruise control, either. Even little things like how bright the blue indicator for the high beams is in the dash. It's so bright that it blinds me, totally negating the high beams all together. The whole truck rattles, shakes, bangs, and flaps. Did they even USE screws or fasteners on this rolling lego set? It's like one of those old snap together model cars. Nothing fits just right, just enough to go together. My guts hurt from being bounced around so much all night. Could they have TRIED and made it ride worse? Doubt it.

Pluses? Well, it has one kick butt cup holder. The sleeper has lots of room, too. It does turn on a dime.

I pulled over twice last night to do a parked re-gen, too. I'll NEVER own that moronic set up. When the figure out something else, I may consider a new truck, but as long as there is a DPF on a truck, it WON'T have my name on the title.

Wheew!!! That felt kinda good and offset how angry I was after getting out of that Fisher-Price wanna be crap heap this morning!!

If you like a rattling, windy, noisy, flapping, cheaply put together truck with lots of cheesy looking fake plastic chrome that doesn't have any foot room, this is your truck!

 

You are trying to rewrite history it was Ronald Reagan that set and fast tracked the diesel pollution specs. You remember him, he did not remember anything, alzheimer, but his astrologer, and Nancy figured how to triple the deficit. Do you miss Jimmy yet! We were talking about an engine in a truck, and how it works and the problems people are having and what he thinks about it and you come in pedaling BS. At least get you facts right. Just a thought!
