Is the Road Ahead Getting Thinner?

摘要

For nearly two decades, emissions mandates have been the leading concern for builders of diesel engines for trucks and buses, observes Bengt Otterholm of Volvo Group in Gothenburg, Sweden. Few regions of the world were unaffected, as regulators targeted unhealthy diesel par-ticulate matter and oxides of sulfur and nitrogen. From Seoul to Sao Paolo, Toronto to Taiwan, much of the world is now at or close to the Euro V emission standard for new equipment, and many countries are preparing to roll up to Euro VI over the next four years.
