2 Stroke vs. 4 Stroke Engine Comparison

How many cycles does a 2 Stroke Engine complete in one revolution of the crankshaft?

• 1

• 2

• 4

• 8

What is the primary difference in the working principle of a 2 Stroke Engine compared to a 4 Stroke Engine?

• 2 Stroke Engines complete a power cycle in two strokes of the piston, while 4 Stroke Engines require four.

• 2 Stroke Engines use only air as the working fluid, while 4 Stroke Engines use a mixture of air and fuel.

• 2 Stroke Engines cannot operate upside down, while 4 Stroke Engines can.

• 2 Stroke Engines use electric spark plugs, while 4 Stroke Engines use compression ignition.

Which engine typically has a higher fuel consumption?

• 2 Stroke Engine

• 4 Stroke Engine

• Both have similar fuel consumption

• Cannot be determined

Which engine generally produces more power for a given size?

• 2 Stroke Engine

• 4 Stroke Engine

• Both produce equal power

• Depends on the fuel used

Which engine type is considered to have a greater environmental impact due to emissions?

• 2 Stroke Engine

• 4 Stroke Engine

• Both have similar environmental impacts

• Environmental impact is unrelated to engine type

Which engine type generally requires more frequent maintenance?

• 2 Stroke Engine

• 4 Stroke Engine

• Both require the same amount of maintenance

• Maintenance frequency is unrelated to engine type

In a 4 Stroke Engine, what is the correct sequence of strokes?

• Intake, Compression, Power, Exhaust

• Compression, Intake, Power, Exhaust

• Intake, Power, Compression, Exhaust

• Power, Intake, Compression, Exhaust

What is a unique feature of 2 Stroke Engines in terms of lubrication?

• They have a separate lubrication system.

• They do not require lubrication.

• Oil is mixed with fuel for lubrication.

• They use water for lubrication.

Which engine type is typically lighter and simpler in construction?

• 2 Stroke Engine

• 4 Stroke Engine

• Both are similar in weight and complexity

• Weight and complexity depend on the specific model, not the engine type

How does the power output of a 2 Stroke Engine compare to a 4 Stroke Engine of the same size?

• It is higher in a 2 Stroke Engine.

• It is higher in a 4 Stroke Engine.

• It is the same in both engines.

• It cannot be directly compared.
