Less pollution
Longer-lasting
Why do two-stroke engines have fewer overheating concerns?
They operate at lower temperatures
They use water cooling
Each new charge cools off the chamber
They have a more complex cooling system
What is a disadvantage of two-stroke engines compared to four-stroke engines?
Less power
More expensive to manufacture
More harmful emissions
Heavier
Why are two-stroke engines not commonly used in cars?
They are too powerful
They are too noisy
They are too expensive
Lack of a dedicated lubrication system
What does the oil and gas mixture do in a two-stroke engine?
Only lubricates the system
Only powers the engine
Lubricates and powers the engine
Cools the engine
Why do two-stroke engines produce a lot of pollution?
They operate at higher temperatures
They use low-quality fuel
New charges of air and fuel sneak out through the exhaust port
They have a complex exhaust system
In what applications are two-stroke engines primarily used?
