The new Sirion 1.3 litre launched in 2005 featured the world's first self-regenerating catalyst. This innovation is also shared by the new Copen.
It effectively extends the life of the catalytic converter, reducing maintenance costs and is kinder to the environment as it keeps the catalyst ‘healthier' over a higher mileage meaning the already low 140 g/km does not increase as the engine becomes older.
This revolutionary technology works by providing a self-regenerating capability in the particles of the precious metal which normally degrades.
Using nanotechnology, the intelligent catalyst incorporates metallic ions of palladium, the most heat-sensitive of the metals used in a catalytic converter.
According to temperature and available oxygen, the particles turn in and out of a crystalline state therefore regenerating and prolonging the cat's ability to clean exhaust gasses.
