I'm not from Missouri, but when you claim a two-stroke engine can be cleaner and more efficient than a four-stroker, you are going to have to show me. Detroit Diesel tried for years. EMD tried for years. No joy.

If you say a two-stroker makes more power per unit weight and is more reliable I would tend to agree. If you told me they are more fuel flexible, I'd tend to agree.

I alluded to the Junkers Jumo because its power-to-weight ratio was very high for a diesel and power-to-weight ratio is important for vehicle engines. I knpow opposed piston two-strokers were used in marine andstationary applications. Fairbanks-Morse diesels built in the 1930s are still in continuos-duty service. If I'm not mistaken, the MAN engines in the Graf Spee were opposed-piston nine cylinder two stroke diesel engines.

I am still completely mystified as to how you would package the engine shown in the original video in a motor vehicle.
