Engine Fuel Rail Pressure Regulators control fuel pressure within the fuel rail to ensure optimal engine performance. They maintain consistent pressure by adjusting fuel flow based on engine demands. These components are critical for efficient fuel delivery and combustion in modern fuel systems.

Engine Fuel Rail Pressure Regulators and Fuel Systems specifications:

Size: Typically ranges from 10 mm to 25 mm in diameter, depending on application.

Grade: Automotive-grade materials meeting SAE, ISO, or OEM standards.

Viscosity: Compatible with fuel viscosities of 0.5 to 5 cSt at operating temperatures.

Buoyancy: Minimal buoyancy impact; designed for stable fuel pressure control.

Material: Common materials include stainless steel, aluminum, or high-grade plastics (e.g., POM, PTFE).

Pressure Range: Typically 2 to 20 MPa (300 to 3000 psi) for gasoline/diesel systems.

Temperature Range: -40°C to +150°C (-40°F to +302°F) operational tolerance.

Seals: Viton, NBR, or FKM for fuel and chemical resistance.

Flow Rate: Varies by design, commonly 1 to 10 L/min.

Regulation Accuracy: ±1% to ±5% of set pressure.

Compatibility: Suitable for gasoline, diesel, ethanol blends, and biodiesel.
