How working marine 2 stroke engine?

A marine 2-stroke engine operates by completing a power cycle in just two strokes of the piston, which means it produces a power stroke with every revolution of the crankshaft. It achieves this through a combination of intake and exhaust processes that occur simultaneously, allowing for a more compact and lightweight design. Fuel and air are mixed and drawn into the combustion chamber, where they ignite, generating power, while the exhaust gases are expelled through ports. This design results in higher power-to-weight ratiOS, making 2-stroke engines popular in marine applications, despite concerns over fuel efficiency and emissions.
