Scania bus and coach engines are equipped with Scania EGR (exhaust gas recirculation) to guarantee compliance with emissions regulations at all times and in all driving conditions, from the stop-go traffic of urban environments to long-distance cruising on the open road.

Scania EGR is a patented recirculation system that attacks emissions in the combustion chamber before they arise. A controlled amount of the exhaust flow is cooled by an EGR cooler and recirculated into the engine to achieve a lower combustion temperature that reduces nitrogen oxide emissions to the required levels. Particulate matter is handled by Scania’s high-pressure injection system for Euro 4, and by a particulate filter for EEV. No additives or extra tanks are required.
