Control Method Of Serial / Parallel Boosting System With E-Boosting Devices

Defensive Publications Series

Two-stage turbochargers are often used for IC engines to achieve higher overall pressure ratios resulting in increased the power density within the short duration of the intake valve opening. A typical two stage application may use the first turbocharger for pre-compressing the air (low pressure compressor) while the second compressor lifts the boost pressure to the desired level. A serial compressor and parallel turbine configuration often causes knocking and control issues for engine because of different pressure in different manifolds. The proposed solution uses electric motors on both the shafts to maintain desired pressure in exhaust manifolds.

Integrated Cast Noise Suppressor On Compressor Housing With Ported Shroud

Defensive Publications Series

Ported Shroud for a compressor housing allows air from downstream of compressor wheel inducer to recirculate back to upstream in order to increase flow stability and avoid surge. However, this results in an increase in noise produced by the compressor. Noise suppressors that are typically added at the inlet to address this problem make inlet assembly complex and increase the cost. The proposed solution addresses this issue with a novel design of a ported shroud in which noise suppressor is integrated into the compressor inlet and cast as a single component.
