or: How to incorporate electric superchargers to turn an Atkinson cycle engine into a Miller cycle engine.
Answers 'How', but should be asking "Why?"
These are excerpts from the paper:
"A turbocharger increases the power available to an integral combustion engine ..."
Available from, not available to. And the "I" in "..IC engine" is internal, not integral.
"A diesel turbocharged system can have turbines also arranged in series, which increases pressure in the exhaust manifold to an extent gasoline engines can not support. In such systems (SCPT - serial compressor, parallel turbine), as the serial compressors drain over the whole engine operation range drawing different amount of power from the shaft (provided by the turbines), the pressures in the two manifolds tend to differ with standard turbos. This leads to the knocking and control problem for the engine."
The term "knocking" I associate with pre-ignition, an air fuel mixture being spontaneously ignited prior to the intended ignition point. This doesn't happen in diesels due to there not being any fuel to pre-ignite prior to the intended ignition point (injection start).
There's more than typographical errors sprinkled throughout implying a non-reviewed paper
"2. PROPOSED SOLUTION OF THE PROBLEM"
"...The proposed solution is two-stage turbocharger system with electric motors (E-boosting) for both the stages. The presence of the electric motor on the turbocharger shafts are allowing to balance the energy demand from the exhaust gas..."
"...The proposed method of using E-boosting for Serial / Parallel two stage turbocharged engines has following main advantages..."
The less than natural syntax and choice of vocabulary is what I see in spam and phishing attempts and what "Susie" at the off-shore call center uses.
And why bother? Put in sequential turbos. Or eliminate all the hot side and turbine issues with electric motor driven superchargers. Or use the electric power for a drive assist motor.
If this paper is merely a means of having a 'patent' in one's name to put on a CV for a job interview, then well done.
Otherwise it's a waste of bandwidth and ink.
