What is a characteristic of a 2-stroke motor?

• A. It uses an oil/gas mixture
• B. It operates without oil
• C. It is designed for larger boats
• D. It uses separate oil and fuel systems

Answer: (A)

A 2-stroke motor is characterized by its use of an oil/gas mixture, which is a fundamental aspect of its design and operation. In a 2-stroke engine, fuel and oil are mixed together before being introduced into the combustion chamber. This mixture not only powers the engine but also lubricates it, reducing wear and tear on internal components that would otherwise be subject to friction. This characteristic is particularly important for smaller engines, such as those found in personal watercraft or smaller boats, where the simplicity and performance of a 2-stroke engine provide advantages in weight and size. Conversely, larger, more complex engines typically use a different system of lubrication, which is why the other options do not apply to a 2-stroke motor.
