The Fuel Oil Viscosity Regulator in marine engines ensures optimal fuel viscosity by heating and controlling fuel temperature. It maintains consistent fuel flow and combustion efficiency for smooth engine operation. This system is critical for reducing wear and improving performance in marine diesel engines.

Key specifications and technical properties of the Fuel Oil Viscosity Regulator, Marine Engine Controls:

- Size: Typically ranges from 100 mm to 500 mm in length, depending on model and application.

- Grade: Marine-grade, compliant with ISO 8217 standards for fuel oil.

- Viscosity Range: Adjustable, typically 2 cSt to 700 cSt at 50°C.

- Buoyancy: Not applicable (non-floating component).

- Material: Stainless steel (AISI 316) or brass for corrosion resistance.

- Operating Temperature: -20°C to 150°C.

- Pressure Rating: Up to 10 bar (145 psi).

- Connection Type: Flanged or threaded (1/2" to 2" NPT/BSP).

- Control Method: Pneumatic, hydraulic, or electronic.

- Compliance: Meets IMO, SOLAS, and MARPOL regulations.

The Fuel Oil Viscosity Regulator and Marine Engine Controls typically comply with maritime standards such as ISO 8217 for fuel quality and IMO MARPOL Annex VI for emissions. Specific compliance depends on the manufacturer and product specifications.
