U.S. EPA unveils new emissions standards for Model Year 2027 and beyond

The U.S. Environmental Protection Agency (EPA) has adopted a new set of emissions standards for heavy-duty vehicles and engines that will apply beginning in Model Year 2027 – placing a…

Canada commits to zero-emission truck sales targets and incentives

Zero-emission vehicles (ZEVs) will need to account for 35% of Canada’s medium- and heavy-duty truck sales as early as 2030, under a series of sales targets and incentives unveiled in…

NOx emissions rules to tap into Canadian research

Previous Canadian research into fuel efficiency has focused on factors such as aerodynamics. (File photo) OTTAWA, Ont. – Canada largely adopts vehicle emissions standards established in the U.S., but a…

How far should Ontario’s emissions crackdown go?

Cleaner air comes with a price tag. It’s paid every time equipment evolves in the name of controlling emissions. A tighter focus on particulate matter gave us diesel particulate filters. When regulators squeezed the allowable levels of NOx, we saw the widespread introduction of exhaust gas recirculation and diesel exhaust fluid. The current push to reduce greenhouse gas emissions has led to the rollout of everything from new oil categories to aerodynamic refinements and lighter components. Even battery-electric and hydrogen-electric trucks are now on the horizon.

Regulators look to further reduce NOx in truck exhaust

The U.S. EPA is placing a particular focus on NOx produced under low-load conditions, such as when trucks are in stop-and-go traffic. WASHINGTON, D.C. – The U.S. Environmental Protection Agency…

Ontario reworking emissions tests for trucks

TORONTO, Ont. – Ontario continues to rework its emissions testing program for heavy-duty vehicles following a decision to cancel Drive Clean tests on light-duty models. Environment Minister Rod Phillips promises it will come "in the near future".

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.
