What makes a two stroke engine produce twice as much power as a four stroke?

A 2-stroke engine makes power every2 cycles were a 4-stroke makes power every 4.Hence 2x power.
This is absolutely INCORRECT! A two stroke engine develops it's PEAK horse power twice as fast as a four stroke for the reason given but that is it. For a given displacement a four stroke engine will ALWAYS make more torque and horsepower than a two stroke engine of equal displacement. This is due to the fact that a four stroke engine cleans the cylinder of contaminated (exhaust) air, compresses the air/fuel to a more efficient level, and draws a cleaner air/fuel mixture into the cylinder as there is no slow burning, air/fuel mixture contaminating oil mixed in the combustion charge. I have over forty years experience working on engines, and can tell you, the ONLY reason two stroke engines have lasted this long, is due to the fact that they weigh less than an equivalent horsepower four stroke engine. If they DID develop more horsepower, the four stroke would not have become the standard internal combustion engine used in transportation, generators, air compressors and the like.

Which supplies more power a 4 stroke engine or 2 stroke engine?
2-stroke engines produce much more power than 4-stroke.
How does engine produce heat?
From the result of combustion during the power stroke of each cylinder.
What stroke of a 4 stroke engine provides power to the crankshaft?
the power stroke
How do 2 stroke engines provide more power than a 4 stroke?
In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc
Why do most very small engines operate on a two-stroke cycle?
two-stroke engines can produce more power than four-stroke engines that have the same size. they can occupy small spaces and produce the desired power. they are on the other hand produce more pollution than 4-stroke engines. that's why they are limited or suitable for small engine spaced machines
What type of engine delivers power with every down stroke of the piston?
2-stroke engine
What are the four strokes of a internal combustion engine?
intake stroke, compression stroke, power stroke, exhaust stroke in that order
Why does the burned gasoline do more work on the piston of an automobile engine during the power stroke?
The combustion cylcle (power stroke) forces piston down to create engine power.
What are the major difference between 4stroke engine and 2stroke engine?
A four stroke engine has 4 strokes per cycle, whereas the two stroke engine has only 2 strokes per cycle. Since the 2 stroke engine has twice as many power strokes as a 4 stroke engine at a given rpm, the 2 stroke is capable of making nearly twice the power of a 4 stroke for a given displacement.
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
How power is affected by the diameter and stroke length of the cylinder of an ic engine?
if the diameter of cylinder and stroke length of an I.C. engine is greater then the power output is more.
