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.

Eaton taps into electric, connected expertise

ATLANTA, Ga. – Eaton’s commercial vehicle group is leveraging broader automotive and electric expertise as it prepares for a future that is increasingly electrified and connected. A newly launched e-mobility business segment – combining elements of the company’s vehicle group and electrical business – is one of the latest signs of that. “There’s going to be a requirement for more power electronics on board,” observed Larry Bennett, director of vehicle technology and innovation, referring to the possibility of three-voltage systems on commercial vehicles. Eaton Electrical, currently responsible for 60% of company revenues, will help to apply lessons from buildings, leading to new smart power management tools and power distribution strategies, he said. There’s already been an increase in electric powertrains for buses and lighter vehicles, of course. And Eaton expects fully electric valvetrain actuation to be a reality within a decade. Hydraulic lash adjustments, now used in passenger cars, could soon manage intakes and exhaust in heavy vehicles as well.

Tesla Class 8’s will hit Canadian roads

MONTREAL, QC - More than 30 of Tesla's new fully-electric Class 8's could be on the road in Canada as soon as 2019. Three companies - including Canadian grocery and pharmacy giant Loblaw Companies - have wasted no time in making the move to the newly launched trucks. Tesla showcased the new Class 8 vehicles with an unveiling event in California last Thursday. Loblaw, J.B. Hunt, and Walmart announced Friday they each had secured pre-orders with the company. Although a final price for the trucks hasn't been listed yet, Loblaw put deposits of $5000 per truck on 25 of the vehicles, currently set to be released sometime in 2019. Walmart is also reporting a buy-in of 15 trucks, 10 of which will go to its Canadian operations, while the others will go to operations in the United States.
