Which type of engine do gas-powered tools commonly rely on?

• A. V8 engine
• B. 2-cycle engine
• C. 4-cycle engine
• D. Diesel engine

Answer: (B)

Gas-powered tools commonly rely on a 2-cycle engine due to their lightweight and efficient design, making them particularly suitable for portable tools and equipment used in rescue operations, landscaping, and construction. A 2-cycle engine completes a power cycle in two strokes of the piston during one crankshaft revolution, which allows for a simpler design that often results in higher power-to-weight ratios compared to 4-cycle engines. This characteristic is especially advantageous for tools that need to be easily handled and maneuvered in various environments during rescue missions. Additionally, 2-cycle engines typically require a fuel mixture that combines oil and gasoline, which allows for lubrication within the engine, contributing to its compactness and efficiency. While 4-cycle engines are more fuel-efficient and produce fewer emissions, they tend to be bulkier and heavier, which is not ideal for hand-held or portable gas-powered tools. Consequently, the design and operational requirements of many gas-powered tools align closely with the benefits offered by 2-cycle engines.
