In my personal experience, diesels seem to have sweet spots. My F250 can get a 10% increase in fuel economy just by keeping it at 2000 RPMas much as possible.

Based on that observation, it seems that a diesel-electric series hybrid would be the most efficient configuration. Series meaning electric only drive with a small battery or super capacitor bank for acceleration demand, with a fixed RPM diesel generator providing recharge and sustain power.

why did the epa stomp out the two stroke engine?

because of the smoke the article talks about?

you’d think they’d have figured out a way to tamp down on the smoke. judging by the article it looks like they have but its taken 40 years and counting

Shouldn’t that be knock.
