the 2 stroke has more rpm than 4 stroke because it has less moving parts and the cycles are faster because there is only 2 and in the 4 stroke there is 4
Combustion piston engines can have two different work cycles, 2-stroke and 4-stroke. 2-stroke tends to have a better power to weight ratio, but pollute more. A 4-stroke outboard is simply an outboard engine that works the same way as a car engine.
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
OPtherwise known as Internal combustion engine with 4 cycles- Induction, compression, power and exhaust
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
Depends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust strokeDepends on if this engine is a 2 stroke, 4 stroke, or rotary engine.

'a 4 stroke engine cycle' is usually what it is called...
4 stroke
4 stroke
2-stroke engines produce much more power than 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
i say that a 4 stroke is faster than a 2 stroke
