Most engines are what kind of engine?

Turbine Engine

Most gasoline engines are four stroke engines which is also known as the Otto Cycle. 1) Intake 2) Compresson 3) Ignition 4) Exhaust (four strokes)

Hmm, I think this is unfriendable material. But, to answer you question... They are similar in many ways. They are both engines... And, that's it. I can tell you many ways that they differ though ;D

Google all the way matey

If you have the owner's manual for the vehicle the engine came in you could look it up based on the climate in your area. If no owner's manual is available you call your local GM dealer as you did...
