Quick Answer: What are the benefits of 4 stroke engine?

What are advantages of 4 stroke?

More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.

What are 3 advantages of 4 stroke engines?

Advantages:

  • Four stroke engines give higher efficiency.
  • It creates less pollution.
  • Less wear and tear due to good lubrication system.
  • It is quitter in operation.
  • It runs cleaner due to no extra oil added in fuel.
  • They give high rpm at low power.

What are the pros and cons of 4-stroke engine?

Four-stroke engines have more parts, therefore they are more expensive and repairs cost more. Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not. Four-strokes are more environmentally friendly; in a 2-stroke engine, burnt oil is also released into the air with the exhaust.

What are the advantages and disadvantages of 2 and 4 stroke engines?

More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.

Why is four stroke most preferred?

The fact that the 125cc 4 stroke engine can make more torque under low RPM is what makes it one of the most preferred engines these days for any vehicle. The low RPM of the 4 stroke engines greatly enhances its lifecycle.

Why are 4 stroke engines better than 2 strokes?

Four-stroke pros: Four-strokes only make power a quarter of the time versus half the time like two-strokes, but a longer power stroke nets a lot more torque, so four-strokes make better power at lower rpm and more linear and predictable thrust throughout the rev range.

Does 2-stroke or 4 stroke have more power?

Pros of a 2-Stroke Engine:

No valves, simpler construction. Fire once per revolution which means that I has a higher power output than a 4-stroke engine. It is lighter, thus making it cheaper to manufacture. They have potential for twice the power than a 4 stroke engine of the same size.
