What are the advantages of four stroke engine?

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 the advantages and disadvantages of a 4 stroke engine?

4 Stroke Engine Advantages and Disadvantages

  • Advantages. More torque. …
  • Last longer. Four stroke engines last longer and use much, much less oil. …
  • Run much cleaner than 2 strokes. …
  • More efficient use of gas. …
  • Disadvantages. …
  • Half as powerful as two stroke engines. …
  • More expensive than 2 stroke.

What are the advantages and disadvantages of a two stroke and four stroke engine?

Advantages: A two stroke cycle engine has twice the number of power strokes than the four stroke cycle engine at the same engine speed. For the same power developed, a two stroke cycle engine is lighter, less bulky and occupies less floor area.

Why are 4-stroke engines 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.

What’s the difference between 2stroke and 4stroke engine?

For a 4- cycle engine the piston moves up and then down the engine cylinder 4 times to accomplish fuel intake or induction, compression, fuel ignition (combustion) and exhaust. In a 2 Cycle engine this is done in 2 piston strokes (one up and one down the piston cylinder).

What are the advantages and disadvantages of a two-stroke engine?

– Two-stroke engines are lighter, and cost less to manufacture. – Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution. Disadvantages of 2 Stroke Engines: – Two-stroke engines don’t live as long as four-stroke engines.

Which engine has more volumetric efficiency?

The vehicle manufacturers try to improve the Volumetric Efficiency of an engine in many ways. However, this can be done most efficiently by compressing the incoming charge by using the forced induction method. Hence, the turbocharged/Supercharged engines have more than 100% Volumetric Efficiency.
