Question by bri bri: What is a four-stroke engine and what are some machines that use them?
I’m writing a paper on the explanation, examples, and disadvantages of a four-stroke engine. Help please?
Answer by Bungholio
A 4-stroke engine is an internal combustion engine that operates in four cycles: Intake, Compression, Combustion, and Exhaust. They are cleaner burning and quieter than 2-stroke (that must use a gas/oil mixture); think a Harley and a motocross bike. Anyhoo, most gas lawn mowers use 4-strokes, as opposed to gas weedeaters that use 2-strokes.
Oh…disadvantage…a little cabon monoxide in the exhaust fumes, maybe.
