The Diesel engine, often have its peak torque at a lower RPM then red line,
(car gasoline engine too) this means it can drive the fixed pitch propeller
faster during take off and climb then the usual aircraft engine does under
the same criteria. result better climb.

The Diesel does have a strong punch and need some torque oscillation
dampenng, but that is not anything new, Junkers jumo used it in the -30th

Deltahawk did ruin a prop on there diesel during ground test.

Hi group,

can someone please tell me whether efforts are on the way already to
turn the Smart CDI diesel engine into an aircraft engine? I'm looking
for something (preferably a diesel) in the 80HP range. Maximum weight
should be appr. 75 Kg (165 lb). It looks to me the larger of the
Smart CDI's might fit the bill.

isn't this exactly what they do in the FK-9 smart?
or is that the petrol engine?
