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
2 stroke, more power and torque = more speed 4 stroke, more reliable
2 Strokes make much more power per cc than 4 strokes. For example a 2 stroke 125 and a 4 stroke 250 both make about the same power 4 strokes have much more low end torque though
2 stroke means it takes two strokes for a power stroke and 4 sroke takes four strokes for power stroke so in otherwise 2 strokes are way faster and more torqey
A 2-stroke dirtbike will be powered by a 2-stroke engine and a 4-stroke dirtbike will be powered by a 4-stroke engine. For the same power, the 2-stroke will be a lighter bike. For the same weight, the 4-stroke will be a weaker/slower bike. The 2-stroke is likely to use more fuel and make more noise. The 4-stroke will run cleaner and quieter.
2 stroke motorbikes are more powerful and I'm not sure on the advantages of a 4 stroke motor bike but i have a 4 stroke and i think its more for beginners
2-strokes are cheaper, and give you more power over a 4-stroke. However, they require more maintenence, you have to mix the oil with the gas everytime you fill up, and they don't last as long as a 4-stroke. Personally, I would take the 4-stroke for convenience and longevity.
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
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.
Really depends on what kind of power you want. a 2-stroke will tear through it's gears faster and overall accelerate faster. 2-stokes have a wider, harder-hitting powerband where the power is mostly at high rpms. a 4-stroke has the low end power- no clutch wheelies, tearing the bead off the tire..so which is more powerful? all depends on when you want the power. 4-strokes low speed, 2-strokes mid-high speed
