The technology might be available to help operators meet exhaust emission targets, but who is going to pay for it?

摘要

Investigations taking exhaust temperature profiles of different vehicles run by various operators have verified that, in city duty cycles, most vehicles will not meet the required exhaust gas temperature to regenerate and self-clean carbon build-up. This is well known by major operators and TfL using pre-Euro 4 and 5-engined vehicles.
