I've heard that one plug sparks on the compression stroke, much like any other engine out there, and the other sparks on the exhaust stroke, it's supposed to offer a more complete burn as well as reduced emissions. I could be wrong, it's just what I've heard.

Rotary engines have the same setup. 2 plugs per rotor.

Gotta love the good ole Lima's, enough spark plugs for a v8, without all that pesky horsepower
