Of course if you keep the same stroke. But then you have a bigger displacement engine !

No, it won't because actually there's less friction area on the cylinder walls with an increased bore for the same displacement. It's just a simple geometry question. A 5-liter V8 with 99 mm bore and 81 mm stroke has a what I call a "cylinder area" (cylinder circumference x stroke x number of...

Higheta, have a look here, I think you'll find a comprehensive answer : http://www.auto-innovations.com/site/document/power2.html Cheers Aorangi

At 19'000 rpm, the maximum piston acceleration in a BMW P83 of formula 1 is 10'000 g . http://scarbsf1.com/BMW_P83/index.html http://forums.atlasf1.com/showthread.php?s=&threadid=61653%20http://scarbsf1.com/BMW_P83/index.html Cheers Aorangi

Formula 1 engines are actually around 26 m/s mean piston speed and 41 m/s maximum piston velocity at redline.

Extremely comprehensive information about every concepts of supercharging, turbocharging and turbocompounding here: http://www.auto-innovations.com/document2/doc-engine.html There's a small charge, but it's worth it. Cheers Aorangi

Beautiful CAD pics of the R-3350 here: http://www.enginehistory.org/vicenzi.htm It was also proppelling the the DC7s Vovo and Scania produce turbocompound truck's engines. Turbocompounding history here: http://www.histomobile.com/histomob/tech/2/113.htm Cheers Aorangi

Thanks a lot to you also, Greg, I really appreciate. Cheers Aorangi

Thanks a lot, SBBlue, it definitely helps. That's what I suspected at first but my knowledge about catalytic converters is really poor and I was assured it cannot by so be a knowledgable friend. Also page 522 of the Bosch Automotive Handbook states that with a 3-way catalytic converter...

On the BorgWarner Turbo systems, which seems to provide outstanding and up-to-date info, we find this : http://www.3k-warner.de/en/products/t_temp.asp "The air ratio lambda at the rated output point is currently about lambda=0.75–0.85 since a portion of the fuel is used to cool the inside...

Yes, the famous Napier Nomad (the Lion was a pre-war spark ignited W12 with 3 banks of 4 cylinders). It's been talked about on thread thread71-63511 and thread71-48738 in which the gas generator principle was also mentioned. I think the gas generator concept would have been more suitable for...

PJGD, Sorry I hadn't seen this interesting thread before ! Your paragraph... "My view is that there is still room for growth in divided chamber combustion systems if higher engine speeds are believed to be the way to go; the piston is much lighter, and the combustion system has more...

Yes Kasey. More info here: http://www.histomobile.com/histomob/tech/2/118.htm Cheers Aorangi

The articles I gave the links in my post of Mar 31 are available in English. http://www.histomobile.com/histomob/tech/2/123.htm Cheers Aorangi

I tested the Bar's Leaks Cooling System Sealer. http://shop.store.yahoo.com/rodi/radiatoradd.html On a car with a slight external coolant leak at the head gasket it worked fine and never gave anymore troubles for several years. The engine never overheated neither, even at full load and speed...
