SuperGen is a Belt Integrated Starter Generator (B-ISG) combined with a novel electro-mechanical power split transmission system providing variable speed centrifugal supercharger capability, all in one compact package. This paper initially discusses the analysis of SuperGen application to a gasoline SUV in order to examine the BISG power and voltage mild hybrid functionality trade-off versus fuel consumption reduction on drive cycle. A significant engine down speeding was also applied based on the low speed torque enhancement afforded by SuperGen boosting capability, both transiently, and sustainably at steady state engine operation. This has been demonstrated and reported on the well-published Jaguar Land Rover (JLR) Ultraboost project. Finally, the part load "boost-ondemand" was used to evaluate advanced combustion modes not easily achievable with conventional turbocharger technology, namely; aggressive Miller cycle with early inlet valve closing; EGR diluted stoichiometric homogenous operation and un-throttled lean stratified combustion.
