Opel-Vauxhall details its squeaky-clean 2.0 litre SCR diesel to power its larger cars from next year

摘要

First details of an ultra-low emission 4-cylinder 2.0 litre passenger car diesel engine aimed principally to power its larger and heavier EU 6 compatible cars and Crossovers from next year have been revealed by GM's European Opel-Vauxhall offshoot. Unlike the bulk of its earlier unveiled 1.6 litre EU 6 compatible diesel engine - intended largely for smaller and lighter cars - the new 2.0 litre unit overcomes next year's high Euro 6 diesel emission hurdle not with a NOx storage catalyst, but by way of a notably more complex SCR (Selective-Catalytic-Reduction) system, today's most efficient method to eliminate diesel engine-generated NOx.
