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.
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.
