Q2-Describe the working principle of a two-stroke marine diesel engine

The two-stroke marine diesel engine operates on a cycle that completes its power generation in two strokes or movements of the piston: one up (compression) and one down (power). Here’s a brief breakdown of its working principle:

1. Intake: As the piston moves towards the bottom of the cylinder (on its down stroke), ports (openings) at the bottom of the cylinder are exposed, allowing a fresh charge of air to be drawn in, displacing the exhaust gases from the previous cycle.
2. Compression: As the piston begins its upward stroke, the ports close. The piston compresses the air inside the cylinder, raising its temperature and pressure significantly.
3. Fuel Injection & Combustion: Near the end of this compression stroke, fuel is injected into the highly compressed and hot air. The fuel immediately ignites due to the high temperature. This rapid combustion generates high pressure inside the cylinder.
4. Power Stroke: The high pressure from the combustion pushes the piston downward, producing the power to turn the crankshaft. This is the engine’s power stroke.
5. Exhaust: As the piston moves downwards again and approaches the bottom of its stroke, the exhaust ports are exposed, allowing the burnt gases to be expelled out. Almost immediately after, the intake ports are exposed, and the cycle repeats.

In two-stroke engines, a blower or turbocharger is often used to ensure that the exhaust gases are fully expelled and the cylinder is filled with fresh air for the next cycle.

The efficiency and simplicity of the two-stroke cycle make it ideal for high-power applications like marine propulsion, where continuous and reliable power is essential.
