Summary

The debates on CO2 emissions and fuel consumption portray electric vehicles as a political solution. However, the range of these vehicles is severely limited by available power capacities, especially in real driving conditions. Electrified powertrains, ranging from mild hybrids and full hybrids to electric vehicles with range extenders, provide an alternative. When used in conjunction with an electric motor, combustion engines have very different requirements for catalytic converter systems depending on the specific design and particularly in view of the ‘zero emissions’ image of electric vehicles. This paper describes the application of a new catalyst design the so called range extender catalyst, its design criteria and its impact on tailpipe emissions, especially when used with in petrol engines.
