• Simpler construction

• Quieter operation

Which component is not needed in a two stroke engine?

• Piston

• Camshaft

• Connecting rod

• Crankshaft

Why do two stroke engines have a great power to weight ratio?

• They burn fuel more efficiently

• They have fewer components

• They use heavier oil

• They have more valves

What is a disadvantage of a two stroke engine?

• It is heavier than a four stroke engine

• It produces less power per revolution

• It consumes more fuel and oil

• It requires more maintenance

How often does a two stroke engine ignite compared to a four stroke engine?

• Every two revolutions

• Every half revolution

• Every revolution

• Every four revolutions

Why must care be taken when mixing oil with fuel in a two stroke engine?

• To avoid engine overheating

• so that it is mixed to the proper ration

• To reduce noise

• To improve fuel efficiency

What happens during the compression stroke of a two stroke engine?

• The piston is driven down

• Exhaust gases escape

• A vacuum is created in the crankcase

• The intake port is uncovered

What occurs during the power stroke of a two stroke engine?

• The piston compresses the fuel mixture

• The spark plug fires

• The reed valve opens

• New fuel enters the cylinder

Why are two stroke engines considered multi-position motors?

• They can operate in multiple orientations

• They have multiple pistons

• They use multiple types of fuel

• They have multiple exhaust ports

Which of the following is a result of the two stroke engine’s poor lubrication?

• Shorter engine life

• Increased pollution

• Improved efficiency

• Reduced noise
