A Ship Engine Supplier - Engine Parts

A ship engine is a complex propulsion system that powers vessels by converting fuel into mechanical energy. Key engine parts include the cylinder block, pistons, crankshaft, fuel injectors, and turbochargers. These components work together to ensure efficient and reliable operation during maritime travel.

Key specifications and technical properties of a ship engine and its parts:

Engine Type: Typically diesel (2-stroke or 4-stroke), steam turbine, or gas turbine.

Power Output: Ranges from 500 kW to over 80,000 kW, depending on vessel size.

Size: Varies by type; large marine diesel engines can exceed 15 meters in length and weigh over 2,000 tons.

Grade: High-grade steel, cast iron, or aluminum alloys for components.

Viscosity: Lubricating oil typically SAE 30 to SAE 50, with ISO VG 68 to VG 150 for heavy-duty use.

Buoyancy: Not applicable to the engine itself; ship buoyancy depends on hull design.

Material: Cylinder liners (cast iron), pistons (aluminum alloy), crankshaft (forged steel), bearings (copper-lead or white metal).

Cooling System: Freshwater or seawater cooling, with heat exchangers.

Fuel Type: Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), or LNG for modern engines.

Compression Ratio: 14:1 to 18:1 for diesel engines.

Emission Compliance: IMO Tier II or Tier III standards.
