Okay, when designing or choosing conventional turbochargers, you basically determine which turbocharger will best meet your needs for your application. It is impossible to have an optimally efficient turbocharger, because the output airflow (which determines power delivery) is dependent on so many variables, not the least of which the turbo's A/R.

The systems I'm working with are for experimental HCCI *gasoline* engines, but the technology has been/ will continue to find more and more applications in conventional gas engines.

Basically, the turbocharger has a set of movable vanes inside the inlet housing. When fully extended, these vanes direct the intake airflow to a concentrated region of the turbine wheel... and effectively change the turbo's A/R to be much smaller. When fully contracted, these vanes allow the airflow to impact the entire surface of the turbine wheel and utilize maximum pressure.

So you see, you have full, electronic control of the pressure ratio.

The technology was used in the Porsche 997 and the R10 TDIs as well as pretty much every turbodiesel since the early 90s, because the exhaust gas temperatures are so much lower. Higher temps decrease the life of the turbos by a lot, something we're working on improving too.

So my research involves implementing VVT in gas engines that have higher exhaust temps than diesels but lower than conventional gas engines, creating simulations in Python to model such engines running under different specs and conditions to help determine the turbo reqs
