The four strokes in one cycle of a 4-stroke internal combustion engine?

Explain the Venturi Principle, and give two examples of its use in practical, real-world situations.

Explain the term "bored and stroked" in relation to engines.

What is the difference in an engine and a motor?

Name three measurement systems used to denote which wrench/bolt/nut is which size.

What is "viscosity"?

What are 4 purposes of "motor oil"?

ETA:  here's what I was looking for -- let me know if I'm totally wrong, OK?

Intake, compression, power, exhaust (OR the mnemonic I learned:  suck, squeeze, bang and blow).

Venturi Principle:  See duane_kc  's answer; add the carved wooden screens that were in use in the Middle East for years to cool the air in buildings.

Bored and stroked -- the cylinder drilled out to accommodate a larger diameter piston, and the throw of the crankshaft and the connecting rod increased to lengthen the distance a piston travels.  Increases available power.

Engine takes a substance such as gasoline and converts it to motion (or "power"), motor converts one sort of power/energy (electricity) to another (rotation).

SAE, Metric and British Whitworth are three options.  There may be many more for all I know!

Thickness of a liquid such as oil or paint.

Clean, cool, seal, and lubricate.

No google, no peeking.
