Your first question Micheal... D.O.T. has an outside emissions company set up at "random" scale house to check "random" trucks exhaust. Here southern California, they are almost done building a super coop, on south highway 15 just inside the Nevada - California stateline. It's setup to check everything coming into Ca, trucks and reefer trailers for emissions. So just putting a "mask" on the computer isn't really viable. For your second question. Diesel engines are designed and manufactured with best materials and parts. Tolerances are tighter, forged rotating assemblies, and are purpose built to run under the harshest conditions. Here's a little bit of info you may not know. The injector pressures are very high, very high. Around 25000 to 40000 psi. There is an 8 credible amount of fuel injected into each cylinder. The Cummins ISX, has up to 625 horses and 2050 pound feet of torque, from factory! There are performance companies that can double, almost triple that and, if driven properly, can still be just as reliable. The knocking you hear is piston slap, lifter chatter and some cylinder knocking. The piston slap, It occurs because the fuel combust before top dead center. It combusts once the cylinder pressure is high enough. Diesels are designed for the slap. The motor will get noisier as it gets higher up in the mileage. On old small and big cam Cummins, the air compressor makes a lot racket also. The fan clutch on 3406s make a lot knocking noises too. And lastly... during a normal year of driving, we drive around 12500 miles a year. So it takes between 7 and 10 years to get to a million miles.
That's one thing I can't stand are snakes. We haul raw limestone from a quarry out in the middle of nowhere. We have guys spotting snakes all the time in the middle of the night trying to get near the warmth of the trucks. We're supposed to tarp right there before we leave the property, I say (expletive) no. I wait till I get back to freeway where there is better lighting than just our marker lights.
Micheal. PACCAR is KW and Peterbilt here. I had a truckin bud tell me, PACCAR or no car. Since the new trend now is callin big trucks, Large Cars. I will Never use that term, large car, to describe a truck. Well, unless it's I'm talking about a Volvo. But, I'm sure that will stir the pot a bit. I just want to say, THANKS, to everyone commenting on Micheal questions. We all have kept it civil and adult. It's almost hard to believe there wasnt any pissin matches in any of his question threads. Happy Thanksgiving to all!
Mark... I sure do! I would much rather have a 3406 or C12 or a C15 than this ungodly heavy DD15 I'm drivin now. It pulls well. But, I think it's a problem when a truck, that's empty, the steers weigh 11300. To me, that's a big problem, especially when a company gets paid by the weight. Some reason the company looks at me cross eyed when I say something about it. But what do I know, I'm just a truck driver.
It's funny. It kinda sounds like the engine developers at PACCAR found the old Allis - Chalmers plans. The PACCAR motors were having the same problem, from what I understand. They couldn't keep cranks in them.
It sure is nice to revisit some past builds. Sometimes these little looks at what has been built gives us the motivation or sparks that inspiration one build might have given. These are all great builds. That's just ridiculous somebody would steal a model. In an odd way it's sort flattering that someone liked it so much, they thought they needed more than you. Doesnt make it right though, at all.
