Friday 2010-12-10 Dev. video update and Discussion

Agree that most accounts I've read also mention intercepting at night by spotting blue flames.

Looks like my thread did the trick

Thanks Oleg

S!

Thank you for the update Nice to see things shaping up. In that DB605 video you can see the root of the flame has reddish/yellow but the tip of it is blueish. Could the British and German difference be that Brits and other allies had carburettors and Germans had direct fuel injection in their DB/Jumo/BMW engines. The mixture in a fuel injected engine, like DB-series, is better than in a carburettor engine and high pressure spray of fuel gives more even fill of the cylinder at the right time compared to the suction in a carburettor system.

Also many nightfighter books I have read state blueish flames on British bombers. And there was a talk witha guy who tuned/maintained DB engines and he said the engine tunes were done in a dark room to see the exhaust flame color to adjust the injection etc. correctly.

Ok, have a good weekend all!

However I see the color of exhaust here in DB. Interesting with which gazoline and settings for start Becasue exaust color depending of many-many "settings".

Don't forget that in the Daimler video, (as far as it seems to me) they were starting the engine for the first time, so they went straight into a "break in run" at a much higher than Idle RPM. (it's been a long time since I've built an engine, but I think I'd typically "run in" a chevy big block at about 2000 RPM for about 15 minutes) That kind of RPM will of course produce a hotter flame than a typical start to idle of an already broken in engine. This will also (as Oleg pointed out ) explain the difference between the flame seen at start up and in flight.

Big LOLs. Oleg sure has his work cut out for him. I'd not be surprised if this thread doesn't cure him from appeals to us for help!
