The Big Ship Engine is a powerful marine propulsion system designed to move large vessels efficiently. Key engine parts include the cylinder block, pistons, crankshaft, turbochargers, and fuel injection system. These components work together to convert fuel into mechanical energy, driving the ship's propeller.

Big Ship Engine Specifications:

- Size: Typically ranges from 10 to 15 meters in length, 4 to 6 meters in height, and 3 to 5 meters in width.

- Grade: High-performance marine diesel engines (e.g., Wärtsilä, MAN B&W, or Caterpillar models).

- Viscosity: Lubricating oil viscosity ranges from SAE 30 to SAE 50, depending on operating conditions.

- Buoyancy: Not directly applicable to engines, but engine weight can range from 100 to 2,000+ tons.

- Material: Cast iron, steel alloys, and aluminum for components; high-grade stainless steel for critical parts.

Engine Parts Specifications:

- Pistons: Forged steel or aluminum alloy, diameter up to 1 meter.

- Crankshaft: High-strength forged steel, up to 10+ meters in length.

- Cylinder Liners: Cast iron or steel with chromium plating.

- Bearings: Bronze or babbitt metal alloys.

- Gaskets: Multi-layer steel (MLS) or graphite composites.

- Turbochargers: Nickel-based superalloys for high-temperature resistance.

- Cooling Systems: Copper-nickel alloys or titanium for seawater resistance.

- Fuel Injectors: Precision-machined stainless steel with ceramic coatings.
