Description

The current and planned legal regulations force the vehicle manufacturers to develop modern intelligent drive systems, which should allow a positive shift for the trade-off between minimum fuel consumption and clean exhaust gas. This challenge can be met by a smart hybrid system and its resulting advantages. The present paper examines the effects of an electrically heated catalyst and a hybrid drive as a single measure to reduce nitrogen oxide emissions (NOx). The research focuses mainly on the effects of the measures taken on the catalytic converter light-off, the reduction of NOx peaks generated by the engine and the energy balance. Implementing these findings in individual operating ranges of an overall drive concept appears very promising.
