They didn’t use these in many airframes AFAIK. Diesel weighs about 2lbs more per gallon than avgas.

“Constant torque at all speeds”. I think somebody misread the slide rule.

Well, “relatively constant torque at most speeds within operating range” is harder to say.

Right. They ended up in a bunch of M5 Stuarts in a short output shaft/ big cooling fan version, though.

Air and Space Magazine had an interesting article on the air diesel. An airline tested it, and discovered the fumes were horrible. One pilot at the first stop walked away. They gave up when the pilot’s wives refused to let them bring their uniforms into the house. Great idea, just one small problem!

Juist a question of incomplete/funky combustion at high altitude? I can’t image the fuel itself was bad, being as it’s not that far from jet fuel - unless 40s diesel really was that stupidly high in sulfur compared to today. I’m also guessing that a modern plane with better sealing and an improved air diesel with catalyzing of pretty much any kind would be fine.

Here you go! https://en.wikipedia.org/wiki/Packard_D… I think this is a different engine than I read about but it had apparently the same fate.
The Packard DR-980 is an American nine- cylinder air-cooled aircraft Diesel engine first certificated in 1930. The engine was unpopular despite its economy and reliability due to the unpleasant nature of its diesel exhaust fumes and considerable vibration when running; approximately 100 were built.

Actually this is it. The article discussed how the heads were held on by a steel band, both strong and light. Looks like its this.
