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.
