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 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.


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.

What is the difference in combustion in a 2 stroke engine and a 4 stroke engine?

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


What are the disadvantages of a 4-stroke engine?

For a set amount of power, they're heavier, bigger and use more parts than a 2-stroke engine.


Why do most very small engines operate on 2 stroke?

Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.


What has more power a 2 stroke or a 4 stroke engine?

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


Will a two stroke engine generate more power if it runs with twice as much oil?

No but it might smoke more


What has more power a crf150r or a 85sx?

The CRF150R generally has more power compared to the KTM 85SX due to its larger engine displacement and design aimed at providing higher performance for older youth riders. The CRF150R features a 149cc four-stroke engine, while the 85SX has a 85cc two-stroke engine. However, the two-stroke engine of the 85SX delivers its power differently, often providing a more aggressive power band. Ultimately, the choice depends on rider preference and intended use.


What is the difference between a two stroke dirtbike and a four stroke?

A 4-stroke will run quieter and cleaner. It will rev lower. For a given engine power it'll be heavier and bigger. For a given engine power it'll use less fuel. The engine will need more parts and be more complicated 4-strokes generally have better torque at low revs. A 2-stroke will run noisier and pollute more, It will rev higher, for a given engine power it'll be smaller and lighter. For a given engine power it'll use more fuel. The engine will consist of fewer parts, and be a simpler design. 2-strokes generally have less torque at low revs but do better at high revs.
