Summary

In hybrid powertrain systems the operation of the combustion engine is changed in comparison to an internal combustion or IC engine - only systems. This causes new boundary conditions and challenges for an optimized design of the exhaust aftertreatment system. These specific behavior characteristics have been identified based on results measured with a Toyota Prius III test vehicle on a both chassis dynamometer and road cycle evaluation. NEDC cycle results show a characteristic reduction of catalyst temperature compared to a conventional powertrain as the combustion engine is switched on for only approx. 40% of the cycle time...
