Some day, loggers will be using axes, and two-man buck saws, farm implements will be pulled by horses and oxen only, (they must be the kind that do not emit methane gas), and all boats will be rowed.
Same thing happened to me a few years back. I bought a new diesel pickup (tier 4) and the thing stranded me in the middle of nowhere. The problem was I wasn't driving it fast enough to build up enough heat in order to let the system do a regen. So, 40 miles from a main road in the middle of the mountains it shut down and told me to "see dealer for service". Granted, being stranded for a mechanical issue can happen to any vehicle, emissions related or not. My frustration was that nothing was really broke, but driving anywhere other than on a highway led to an automatic shutdown. And really, how much pollution was I making idling around? Same thing has/is happening with equipment. My dad bought a new tractor a few months back. He mainly uses it for moving round bales and feeding cattle. It never really gets warm enough to do auto regens. He's had to park it, crank the throttle, and let it sit for 20-30 minutes to clear the warning lights. Where's the sense in that?
If we had fewer politicians blowing out methane gases everyone would breathe easier. But that's not happening anytime soon.
If one can afford a Tier 4 tractor, one is already part of the elite in the USA.
Thanks for letting me know that working my *** off for the last 42 years at 65-80 hours a week makes me elite. I had no idea I was so privilaged......
As long as you are not sucking on the muffler of your old girl, you are fine. HSJournal of The American Board of Family Medicine Exhaust from diesel engines is considered to contribute to more than 50% of ambient particulate matter with a mass median aerodynamic diameter less than 10 μm (PM10), greatly contributing to overall air pollution. For fine particulate matter with a diameter below 2.5 μm (PM2.5) and ultra-fine particles with a diameter below 0.1 μm, this contribution is even higher.1 These carbon particles are small enough to be inhaled and deposited in the lungs but have a large surface area. Organic compounds from diesel exhaust with known toxic and carcinogenic properties, such as polycyclic aromatic hydrocarbons (PAH), adhere easily to the surface of the carbon particles and are carried deep into the lungs.4 Diesel engines emit other toxic compounds in disproportionately higher concentrations than gasoline engines, including nitrogen oxides, sulfur oxides, ozone, formaldehyde, benzene, and smaller organic molecules. Diesel engines also produce 26% of the total nitrogen oxides in outdoor air. This is what Physicians think, after substantial research and patient experience. This is not a "Big Government Conspiracy". While it may be permissible to harm yourself, it is not permissible to harm others. Nano particles and organic compounds present in diesel soot do just that. Tier IV emission control eliminates many of these risks. I'm "stuck" with a tractor without Tier IV protection and there's nothing for the present I can do about it. Rather than lament having Tier IV, those whose machinery offers this protection should be thankful.
The problem I have is i really don't believe how some of the manufacturers are meeting tier IV emissions actually lowers the emissions the engine puts into the air. It just lowers the emissions to pass the test. Meeting the emissions without the need for DPF or SCR, that is a different story. All the EPA seems to be concerned about is that you meet the emissions standard not how you get there. Now I'm no rocket scientist, but if you have a filter that catches the soot, then when it starts to plug up, run a regen that burns it off into the air, what are we gaining here. Now you can blow smoke up my butt and tell me that the urea(that is your DPF fluid, it is manufactured piss)that you inject into the catalyst makes a chemical reaction that makes the soot you burn off environmentally friendly. Now one thing I do know piss freezes and that poses all kinds of problems when you have to hang that off the side of your truck or tractor.
Now we all know California has stricter emissions than the the other 49 states. Remember back in the late 70s when we had the AIR pumps on are cars. That is an air pump that ran off the engine(like an alternator) and pumped air into the exhaust manifold. The same guys that came up with the stuff above tried to tell us that the air being pumped into the exhaust was burning the fuel and hence lowering exhaust emission. So, in California they had two AIR pumps and there cars got worse gas mileage. Well guess what that is not how it worked the air going into the exhaust diluted the exhaust so it would pass the test, more air better test results. I maintain in California they where putting more exhaust emissions into the air because per mile they had to burn more gas! I maintain we are doing the same thing with the DPF regen cycle. Think about it, an engine with DPF gets worse fuel mileage. but once again I'm no rocket scientist.:2cents:
