Dirty Secrets: Carriers call for emissions crackdown
TORONTO, Ont. -- Clean air comes at a cost, and it involves the emissions-related changes to exhaust systems and engines, sometimes introducing added maintenance costs and reduced fuel economy in the process. That’s led to one of the trucking industry’s worst-kept dirty secrets. Many truck owners are reprogramming electronic control modules to bypass SCR (selective catalytic reduction) systems, which reduce unwanted NOx by introducing diesel exhaust fluid to the combustion process.
Bosch slashes NOx, without adding components
Flat Rock, Mich. – Bosch says it has pioneered an emissions reduction technology that can cut NOx emissions to 10% of levels seen with current diesel-powered cars, and without adding components. Not only that, the company says the technology can be scaled up for use in medium- and heavy-duty diesel engines. The supplier based in Stuttgart, Germany, unveiled the technology in April and offered further details during a North American press event this week. Alex Freitag, director of engineering with Bosch’s powertrain solutions group, said the new approach to NOx emissions will keep diesel engines in the game for years to come without adding significant costs to the vehicle. "The value proposition of the diesel engine is maintained with a minimal impact on fuel economy," he said.
2021: The Medium-Duty Emissions Odyssey
TORONTO, Ont. -- The next round of greenhouse gas (GHG) regulations is due in 2021, but the model year of trucks affected by the rule will actually hit the road about two years from now. And while fleets that operate Class 7 and 8 heavy-duty trucks are already losing sleep over the rule, a significant share of the population operating medium-duty trucks doesn’t even know these rules exist. They’re the kinds of trucks operated by businesspeople and contractors who sees vehicle as a tool for some other business. Think electricians, landscapers, bakers, and plumbers. Their passion is their business, not the truck they use. "Back when the 2007 and 2010, soot and NOx emissions rules kicked in. We had to educate our customers on those changes, as dramatic as they were," says Brian Tabel, executive director of marketing for Isuzu Commercial Truck of America. "Most of them didn't know the change was in place, but they sure noticed the price jump between 2006 and 2010 [Model Year] trucks. Customers that had bought pre-emissions 2006 trucks and were shopping for another one in 2010 were shocked. They were mostly utterly unaware of the changes that had occurred over the past 10 years."
Invest VW funds in clean diesel: Forum
WASHINGTON, DC - The head of the Diesel Technology Forum has told state environmental officials that new diesel technology offers the most cost-effective way to reduce NOx emissions, and should be considered when investing the US $2.9 billion Volkswagen Environmental Mitigation Trust.
