Difference Between Two Stroke and Four Stroke

  7 Difference Between Two Stroke and Four Stroke

S.NO.	Two Stroke Engine	Four Stroke Engine
1.	A two-stroke engine completes a power cycle in just two piston strokes (one up and one down).	A four-stroke engine completes a power cycle in four piston strokes (two up and two down).
2.	A two-stroke engine has a simpler design and typically has fewer parts than	A four-stroke engine, making it lighter and more compact.
3.	A two-stroke engine produces more power per unit of displacement than	A four-stroke engine, making it more powerful for its size.
4.	A two-stroke engine has a higher power-to-weight ratio than	A four-stroke engine makes it more suitable for applications where weight is a critical factor, such as motorcycles and small power tools.
5.	A two-stroke engine consumes fuel more efficiently than	A four-stroke engine makes it more fuel-efficient for a given power output.
6.	A two-stroke engine produces more emissions than	A four-stroke engine, making it less environmentally friendly.
7.	A two-stroke engine requires the use of special oil mixed with the fuel to lubricate the engine.	A four-stroke engine has a separate lubrication system.
