The Compression Spring for fuel pressure regulator valve regulates fuel pressure within the engine's fuel system. Positioned within the regulator valve, it controls the valve's movement, adjusting fuel pressure according to engine demand. By exerting force on the valve, the spring maintains consistent pressure levels, ensuring optimal fuel delivery for combustion. Its function contributes to efficient engine performance, fuel economy, and emission control for overall engine operation.Attributes:• Withstands tensile stress during operation.• Resistant to wear and tear from constant movement.• Corrosion-resistant materials for extended lifespan.• Total coils are 8.6 and active coils are 6.6.• The helix of the coils is right-hand.• The spring rate is 0.84 Newton per millimeter.Applications: The Compression Spring for fuel pressure regulator valve ensures proper fuel pressure regulation and prevents fuel system malfunctions by maintaining consistent pressure levels, enhancing engine performance, and preventing fuel leaks.
