FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

A beginner's guide to plowing snow with a heavy-duty truck

I live in a desert, so the only things getting plowed around here are mud flows and brewer neighbors. But I enjoy machinery and haven't plowed any snow since a "loaded" truck meant one with A/C and a CD player, so I jumped at the chance for a plow primer in a Ram HD on a Canadian airfield. Running a plow is like welding – the basics come quickly but experience pays dividends. The first thing to deal with is a frequently changing horizon because, stout as they are, even three-quarter-ton heavy-duty trucks will move up and down in front considerably with a 600-to-800-pound plow hanging off, and fast plow hydraulics rival some low-riders for bounce effect. Getting going is easy unless you forgot blocks and the plow froze to the ground, rookie. If you have to drive to your plowing assignment, blade height needs some experimentation to find the best cooling airflow; if you think sub-freezing temperatures negate that concern, remember you've installed what amounts to a 20-square-foot air brake up front that the truck has to overcome, and blowing snow could block some cooling air passages. Whether it's a "straight" blade or V design, always have it tilted to the right lest you catch a hidden post, solid mailbox, or edge of a snow bank. Most plow operators I spoke to rarely exceed 45 mph in transit because of cooling, front suspension travel, and common sense, and you should go even slower if you don't have some ballast like chains, extra fuel tanks, or a salt spreader to balance the load on the back. With trucks' relatively slow steering and all that weight up high, oversteer is best avoided. With a little clean space to get a run, stick it in Drive to gather momentum and lower the plow simultaneously to float, where the weight of the plow rests on and lets it run along the surface. Momentum is good until you hit something you didn't know about, at which point the plow's breakaway systems limit damage but your truck could still hit something big; caution never hurts. Start out at 10 to 15 mph, depending on consistency and depth, making a clean wave off one side. If you have to push it straight, as you slow coincidentally raise the blade at the bottom of the pile to shove it up higher. Carry too much speed here and you'll stop with an unceremonious thud. Common mistakes cited among a few experts were people pushing banks of snow rather than plowing it, and rushing the shift between Drive and Reverse, throttling up before the shift is completed.

Fiat Chrysler Automobiles: The next five years

Unless you've been living under a rock for the past 24 hours, you've no doubt read about all of the big future product news coming out of Fiat Chrysler Automobiles today. We had individual brand reports from Chrysler, Dodge, Jeep, Ram, Alfa Romeo, Fiat, Maserati and even Ferrari, but in the interest of simplifying and summarizing, we're going to list out the hard facts once more. Of course, with all of this still off in the future, there's still the possibility that a few changes will be made. But as of what we know right now, here's what's coming, and what's going away.
