The term 2-stroke, or 2T, refers to the engine's operation cycle. In a 2-stroke engine, the piston completes two movements (up and down) to complete a power cycle, with the combustion taking place every revolution. This contrasts with a 4-stroke engine where four piston movements are required to complete a cycle. The 'T' in 2T stands for 'two', emphasizing the engine's efficiency in terms of power output per revolution.
FAQs & Answers
- What does 2-stroke mean in an engine? 2-stroke, or 2T, refers to an engine type where the combustion cycle is completed every two strokes of the piston, resulting in a power stroke with each revolution of the crankshaft.
- How does a 2-stroke engine differ from a 4-stroke engine? A 2-stroke engine completes a power cycle with two movements of the piston, while a 4-stroke engine requires four movements, making 2-stroke engines generally lighter and more powerful for their size.
- What are the advantages of a 2-stroke engine? 2-stroke engines are typically lighter, simpler, and can deliver more power per cycle compared to 4-stroke engines, making them popular for applications like motorcycles and lawn equipment.
- Why are 2-stroke engines less common in vehicles? 2-stroke engines are less common in vehicles due to stricter emissions regulations, higher fuel consumption, and more frequent maintenance needs compared to 4-stroke engines.
