You might claim to know a lot, but you've just said something that, in terms of physics, is plain, no-question-about-it, simply WRONG.

Torque, or, to use the scientific term, turning moment = force x distance from fulcrum. (Fulcrum means the point about which a turning object - in this case a drive shaft - pivots.)

Power is the amount of kinetic energy produced by the engine, therefore the amount of kinetic energy wich the car has.

Basically, to use equations:

Torque:

M = F x D.

Power:

KE = 1/2 x M x Vsquared.

Incidentally, concerning these two equations, the upshot of the first one is that the greater distance from the fulcrum, the more the torque applied to the ground by your car, so technically, by fitting bigger wheels, you will give your car more torque, but this doesn't improve acceleration, because bigger wheels are heavier. However, this is partly why big wheels are good for rock crawlers, which need loads of torque but not much acceleration. The upshot of the second equation partly explains why 4-stroke engines produce more low-end power, but 2-stroke engines produce more high-end power: as you can see from the equation, where M means Mass, the more rotating mass there is the more power there is. This partly explains the low-end power of 4-strokes; they have a heavier rotating mass, because of all he valves and springs and pushrods that they have. 2-strokes are better at the high revs for the same reason: they don't have any valves, or anything like that, so they have a much smaller rotating mass, so because of momentum (which is another story altogether which i won't go into here) they can rev higher, and becaue the equation tellls us that the more V (Velocity) there is, the more power there is.
This isn't actually the full story, but it is the basic reasons why 2-strokes and 4-strokes are different. The part that I havn't gone into is the chemistry of fuel consumption, and efficient burning of fuel. You probably don't want me to go on about Hydrocarbons for dozens of lines, so let's just leave it at that, eh?

So, there you have it, the PROPER explanation of just what's going on with engines.
