engine Electronics Revisited: EPA may require emission-control diagnostics on diesel engines

摘要

Engine, equipment and emission-control manufacturers will need to keep their lines of communication open for the next several years as regulators focus on their next target in the never-ending push to reduce emissions. Regulators want engine manufacturers to incorporate on-board diagnostic systems into their electronic controls. These systems won't do anything to reduce emissions. Instead they will prevent an increase in emissions by alerting operators when diesel particulate traps, oxidation catalysts and other aftertreatment components begin to fail.
