Note:
The application of a hermetical Stirling engine to a hybrid bus has been investigated.
Due to external continuous combustion the Sterling engine expels few emissions. The main advantage is therefore, that emissions are reduced.
When applied to a serial hybrid urban bus, the usual Stirling engine drawbacks from over-weight, less attractive thermal transient behaviour and slow-acting, complicated power control are minimised. It has been found, that thermal transient effects are of minor importance as the hybrid bus is cyclically operated and as zero-emissions-operation periods are assumed to be of limited duration. Driving performance of the hybrid bus can therefore be satisfactory maintained when the Diesel engine, that usually powers the hybrid bud, is replaced with the hermetical Stirling engine SM4, that has been designed for the investigation.
