What type of engine does the STIHL 460/461 chainsaw use?

• A. Two-stroke engine
• B. Four-stroke engine
• C. Rotary engine
• D. Diesel engine

Answer: (A)

Two-stroke engines are used in most handheld chainsaws because they deliver a lot of power for their weight, which is crucial for a portable tool. In a two-stroke design, the engine fires once per crankshaft revolution, providing strong, rapid power pulses that match the heavy cutting loads you put on a chainsaw. The STIHL 460/461 are gasoline, air-cooled units that run on a fuel-oil mix, keeping the engine simple, light, and easy to maintain for professional use. Four-stroke engines, while common in many machines, would add significant weight and require a separate lubrication system, making them less suitable for hand-held saws. Rotary (Wankel) engines and diesel engines face other practical drawbacks for chainsaws, such as sealing challenges and heavier fuel needs. So the type of engine used by the STIHL 460/461 is a two-stroke engine.
