One of the subjects in Pat Symonds talk is NOx which is greatly reduced in these current F1 engines courtesy of the lower temperatures from lean of peak effect.
Yeah, same with current sophisticated 2-strokes, & FYI Johnny, ol' Pat is on record as favouring
a lifting of the longstanding ban on 2-strokes, for future F1..
Disclaimer: harbour a large bias for 2 strokes having broken and cut much of me on them = Respect for their (once) peculiar power personalities.
I remember Symonds P. bringing that up and wondered if there was influence coming from Walker J.
A comment at the time from one of the fraternity was "he mustn't know engines very much" (why was Pat nominated, self or otherwise, being a self-confessed chassis man. All that aside I am very grateful for the first, that I know of, partial expose for the most intriguing technical revolution of recent times. IMHO.
The brief reasoning for the comment is 1.the inhibition of duration and 2.overlap complications, there is only 360 degrees to deal with all that goings on.
Even with turbocharging and huge gas exchange potential with any manner of port configurations, bore stroke ratio compromises and number of cylinders.
And I'm talking 6K to whatever RPM engines, not 300 RPM marines.
Having said all that, the little SkiDoo goes impressively close!
