Even with videos, I only kinda-sorta-maybe understand how Wankel engines work, and have no idea how a human mind could've come up with the concept, even with chemical enhancement. Well, someone has developed an "inverted" version, which increases efficiency and negates a few of the Wankel's problems. Check out the third video above (the first two are tire commercials), damn.

Both cars were fuel mizers, but would accelerate like a dream!

We used to joke that if we sold Tier 4 equipment to China, we actually be leaving the air cleaner at the exhaust than the intake.

DEF is a 32.5% solution of urea, (NH
2)
2CO. When it is injected into the hot exhaust gas stream, the water evaporates and the urea thermally decomposes to form ammonia and isocyanic acid:
2)
2CO → NH
3 + HNCO
The isocyanic acid hydrolyses to carbon dioxide and ammonia:
3
Overall, this is
2)
2CO + H
2O → 2 NH
3 + CO2
From this point, ammonia, in the presence of oxygen and a catalyst, will reduce nitrogen oxides:[6]
3 + 1⁄2 O
2 → 2 N
2 + 3 H2O and
2 + 4 NH
3 → 3 1⁄2 N
2 + 6 H2O
The overall reduction of NO
x by urea is:
2)
2CO + 4 NO + O
2 → 4 N
2 + 4 H
2O + 2 CO2 and
2)
2CO + 3 NO
2 → 2 1⁄2 N
2 + 4 H2O + 2 CO2

I understand the issues with sulfur, just not sure why you made the leap from politics to sulfur. Politics (EPA) hurt diesels with emissions requirements, not sulfur contaminants in the fuel.
Look at the number of on-highway diesel manufacturers for Semis, Coaches, Buses, etc. Not many left.

For 2019 delivery, even our big shunters (mostly Cummins diesel), which are off highway regulations, will be Euro V, needing adblue etc.
Diesel is not a simple and reliable technology any more.

One day later we bought a brand new '95 Corvette for $35K and trade in.
