EURO 6 UNCOVERED

摘要

At first glance, the OEMs' Euro 6 heavy-duty diesel engines - though technically more complex than Euro 5 - require no more maintenance than the engines they replace. Technicians looking at the standard service schedules will notice virtually no difference, in terms of inspection items, consumables or even service intervals. However, under the covers, the engine management controls are even more sophisticated - particularly around the SCR (selective catalytic reduction) after-treatment. So the challenges come when drivers report dashboard warning lamps up: fault-finding, intervention and repair will be different.
