zianurayThe 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![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
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.

Date: 2009-03-22 09:48 pm (UTC)2. Venturi Principle: Liquids and gases moving from a smaller to a larger area volume decrease in pressure. Used in carburetors and fuel injection systems to mix fuel and air in precise ratios.
3. Bored: Combustion cylinder has been increased in diameter due to polishing or "honing". Stroked: Length of piston rod has been adjusted to give a precise size to the combustion chamber for increased efficiency.
4. No idea.
5. Imperial (inches, feet, etc), Metric (millimetres, centimetres, etc), ?
6. The thickness of an oil. Viscosity 10W is the lowest commonly used in most American vehicles; some engines designed for high-RPM operation will use 5W oil. Variable viscosity oils (i.e. 10W-30) change their viscosity depending on temperature.
7. Assist in engine cooling (especially in air-cooled engines), lubricate moving parts, carry metal shavings away from operating parts, ?

bored - what I was in shop class, and, increase in size of the cylinder - aligned with the crank shaft (hopefully less than the amount of metal left in the cylinder wall, else you will have to sleeve it).
stroked - uh, not going there, and, changing the compression of the cylinder by changing the amount of volume held at the top of the stroke. This can be changed by decking the head and or block, hopefully not enough to allow the valves to hit the piston resulting in catastrophic metal movements..
steam engine in train, motor in car, that is all I remember...
metric, english, or how about BSF, BSW, BSP, NTP, UNC & UNF
the 'thickness' of the oil related to the length of the carbon chain determined by how high up the cracking tower it is pulled...
lubricate, cool, float impurities away, and ???
how'd I do teach?
bw
BTW I HATE tests...
