Does anyone have (and is willing to send) the paper "the pressure exchanger" by Barnes and Spalding, published in 1958-59 or so in Oil Engineering and Gas Turbines Journal?
thanks scott & terry;
I have already checked heywood; especially the chart seems to be useful. I`m studying related chapters in horlock&winterbone right now.
further, I`m seeking gyarmathy`s SAE paper on comprex.
I have also found a paper dealing with the design of press.exhcanger, but it seems...
the turbo is fed by gases from 3cylinders only, but charges all six - so it doesn`t put more stress on one side of the engine.
I think the main reason for this arrangements was to improve bsfc at partial loads and at medium speed rather then increase max. power; thus, max. boost pressure...
guys,
I`ve been looking for comprex dimensions; do you have any idea what its diameter and length and port diameters could be?
or, any tip where could I find a sketch / drawing?
thanks
scania`s DTC1101 turbocompund diesel in mid-90`s has the brake effinciency 46%, todays scania`s turbocompound engines might be also somewhere there if not higher.
However, the highest brake efficiency is (was) reached by large low-speed Sulzer 2-stroke engine, uniflow scavenging, turbocharged...
hi guys,
I`ve been looking for following data: bore, stroke, conrod length, piston pin offset, no. of main bearings, valvetrain type, no. of camshaft bearings, compression ratio, cylinder firing order, valve timing, valve lift, port diameters, fuelling (mm3/inj), used turbo type...
