That a pretty large medium or heavy duty Diesel on the left.

Here's another unconventional engine.

They have one of these from WW1 days at the Dayton Air Force Museum.

It had a super low weight to horsepower ratio, especially for it's day. Really cool!

Maybe it was from the 20’s. I just remember being fascinated by it and my dad talking about how old it was.

an combustion cycle
an fuel injection event

Somebody please clue me in again on what the rules are for "an" versus "a".

My mother would have been upset with the two items.

These alternative engines never seem to make it to market or if they do, they have big problems (Wankel and Orbital).

LiquidPiston, Inc. develops internal combustion engines based on an innovative thermodynamic cycle, increasing average efficiency over conventional diesel engines from less than 20% to more than 50% under typical operating modes. LiquidPiston engines are compact, quiet and powerful, with a lower total carbon footprint for environmental sustainability. The engines are also multi-fuel capable.

For those of us not really on the ball about engine tech, I present the “Turbo Encabulator” video, to explain things.

'An' precedes words that start with a vowel sound.

There was a Monty Python episode once where one guy asks the other to hand him 'an hoop', over-exaggerating the normally-silent 'H' sound. Needless to say, the other guy mocked him mercilessly.

I’d like to see it in operation since for all it appears to be a lobed engine. Maybe they have something but lets see it run.

Been done better actually..

Find me a better way to fit 1000BHp under the hood of my 1978 Camaro and I'm in...

Until then, all you did was invent a better lawn mower motor...

Years ago I got to ride in a Mazda with a Wankel engine. Accelration was very smooth and the car was “quick” (if not all that fast).

But it was brand new.Those engines wore out real fast.

Popular Science reports on a lot of tantalizing technology that never makes it to market. I’d like to have one of those motors in my flying car.
