If you have CNG fueling stations around, though, you're lucky. If
there are any here, I don't know about them. There's one in Newark
(don't go there on purpose, please...) and another on Staten Island.
(only about 10 miles, but the toll is $12 cash, one-way. No thanks.)


FWIW, Flying J and Pilot are rolling out CNG fueling stations to cater
long haul truckers. If this works, then it might be a catalyst for more.

That would be a good step.

I have read, without being able to evaluate it myself, that setting up
CNG fueling stations is fairly easy. Compressors must be powerful,
though, to get that pipeline gas up to transportation-fuel pressures
at high speed.

Does CNG work in a diesel engine? Or does it require spark plugs?

Either one. And a third option: HCCI (homogeneous charge, compression
ignition, like a model airplane "diesel"-that-isn't-really-a-diesel.)

It's getting really tough to follow the research on engine fuels these
days. They're throwing everything at the wall to see what sticks --
including HCCI natural gas supplemented with direct-injected ethanol.
No kidding. It's crazy stuff.

Just look at some of the research paper titles for natural gas:
