Engine smoke trail

[Zakson85]

Ever since the *Il-2* series began, I’ve been intrigued by the developers' approach to the smoke trails left by aircraft. How is it that a P-51 with the throttle set to 70% and the mixture correctly adjusted produces significantly more smoke than an F-86 or MiG-15 at full throttle? Is there any source material that confirms this effect? For instance, some video footage of real aircraft.

That's right, the piston aircraft in the IL-2 series look like they are powered by diesel engines, with a failed turbine.
