2-Stroke Engine Quiz

What is the working principle of a 2-stroke engine?

• No revolution of the crankshaft needed to complete a power cycle

• Four revolutions of the crankshaft to complete a power cycle

• Two revolutions of the crankshaft to complete a power cycle

• Single revolution of the crankshaft to complete a power cycle

What are the advantages of a 2-stroke engine?

• Slower acceleration and heavier construction

• Higher power-to-weight ratio and simpler design

• Lower power-to-weight ratio and complex design

• Noisy operation and higher fuel consumption

What are the disadvantages of a 2-stroke engine?

• Environmentally friendly, cost-effective, longer lifespan

• Excessive pollution, lower fuel efficiency, and higher oil consumption.

• More durable, better performance, cleaner emissions

• Less pollution, higher fuel efficiency, lower oil consumption

Name the components of a 2-stroke engine.

• cylinder, piston, crankshaft, spark plug, intake/exhaust ports

• handlebar, wheels, pedals, chain, gears

• tire, steering wheel, seat, windshield, brake pedal

• battery, radiator, transmission, fuel tank, exhaust pipe

How does a 2-stroke engine compare to a 4-stroke engine in terms of power output?

• 2-stroke engines have variable power output compared to 4-stroke engines

• 2-stroke engines generally have higher power output than 4-stroke engines

• 2-stroke engines generally have lower power output than 4-stroke engines

• 2-stroke engines have the same power output as 4-stroke engines

How does a 2-stroke engine compare to a 4-stroke engine in terms of fuel efficiency?

• 2-stroke engines are generally less fuel efficient than 4-stroke engines

• Fuel efficiency is not a factor in comparing 2-stroke and 4-stroke engines

• 2-stroke engines are more fuel efficient than 4-stroke engines

• 2-stroke engines and 4-stroke engines have the same fuel efficiency

What is the lubrication system used in a 2-stroke engine?

• Recirculating system

• Partial loss system

• Total loss system

• No lubrication system

Explain the scavenging process in a 2-stroke engine.

• The air-fuel mixture is injected directly into the exhaust system

• Fresh air-fuel mixture enters the combustion chamber while exhaust gases exit

• The engine runs on electricity

• The exhaust gases are recirculated back into the combustion chamber

What are the emission levels of a 2-stroke engine compared to a 4-stroke engine?

• Lower

• Higher

• Equal

• Unchanged

Discuss the maintenance requirements of a 2-stroke engine compared to a 4-stroke engine.

• 4-stroke engines require more frequent maintenance compared to 2-stroke engines

• 2-stroke engines require more frequent maintenance compared to 4-stroke engines

• 2-stroke engines require less frequent maintenance compared to 4-stroke engines

• 2-stroke engines require the same maintenance as 4-stroke engines
