... By eliminating exhaust gases pressure build-up inside turbine housing, and so also inside manifolding, and instead of by exhaust gas pressure spinning the turbine the compressor is sinning by MGH-H, extra power is extracted from the engine. This means engine in ‘electric supercharging mode’ power output is higher than engine in turbocharger mode by just eliminating exhaust back-pressure.
false
WGO the 'back pressure' is the same .....
regardless of whether or not the entire exhaust flow bypasses the turbine
the ICE is exhausting to the atmosphere - not to a vacuum
As has been explained by stivala, this is certainly not the case, and teams have been operating in electric supercharge mode when possible maybe since 2014, but have 100% been doing so in 2016. There's obviously a net power gain in doing that at the expense of stored energy.
Juzh - you have above 100% misrepresented what I have written
the matter under discussion is whether .....
waste gate open with all exhaust diverted around the turbine and going to ambient via the WG exhaust pipe is different to .....
waste gate open with some exhaust to ambient via WG exhaust pipe and some exhaust to ambient via turbine
not whether electric supercharge mode exists
