Question

The two-stroke engine is a) simple and expensive c) low power-to-volume ratio b) high power-to-weight ratio d) all of the mentioned

Answer 1

Answer: B) High power-to-weight ratio

Step-by-step explanation:

Two stroke engine is a internal combustion engine and it is cost effective to manufacture. It does not contain valves and it is simple to construction.

Two stroke engine have high power to weight ratio as power is available in the narrow range due to the rotational speed. It basically complete one rotation of crankshaft after completing the one cycle.

Two stroke engine produce the twice amount of power and it reduce the number two stroke engine moving parts so that it can be more packed and lighter.

Therefore, two stroke engine has high power to weight ratio.
