But generally speaking the inertial forces would be higher in a diesel engine due to more parts and heavier parts involved than an gasoline engine ,am I right ?

when they say the inertia forces in the engine,what does it refer to ? this is with respect to the fact that in a diesel engine the point of maximum pressure is at combustion as there are no sufficient inertia forces to cancel out load forces..

can you elaborate when you say 2 separate 2ingle stage turbos i.e parallel?

does the r2s turbo , a 2 stage turbo and a twin turbo mean the same ...well my idea of a 2 stage turbo is that where compression of air takes place in 2 stages ..so does it consist of 2 compressors?

The control has mainly got to do with the ECU then right?

The link says "VGTs have a minimal amount of lag, have a low boost threshold, and are very efficient at higher engine speeds" so that's what I asked. And may I know what you mean by geometry control being fine grained?

So one can still feel the difference when driving at low speeds ...and when shifting to high speeds..but they are really effective only at high speeds na?

In what way does the VTG help reduce turbo lag at low speeds? and can the lag be eliminated completely?

Is this one way of a stratified type charge being utilized?

In what way is compound vortex controlled combustion effective ? and does it effectively reduce emission?

well i happened to see a turbo being assembled ..thats where i saw snap rings ..what material are they made of ..and do you mean to hold together the journal bearings ?

Why are snap rings used in turbocharger core assembly ,and how important are they ?

Well I get your point ,If I know the cylinder pressure and firing pressure at a particular crank angle for each cylinder I can plot pressure vs crank angle . I also seem to have little idea of AVL as i found it being used in a paper though I could not imagine why was it necesary if this plot...

Well I meant AVL BOOST (virtual engine simulation tool) was used to plot the pressure vs crank angle .In my case it is a naturally aspirated four cyl diesel engine ,one of my profs told me I don't have to go for AVL i can plot it theoritically..but I felt it would not be possible as there are 4...
