The Fuel Ratio Control Spring is designed to control the fuel flow by modulating the fuel control valve's opening and closing. As the engine operates, the spring maintains the appropriate tension to regulate the fuel-air mixture, required for combustion efficiency. This ensures optimal engine performance, maximizing power output while minimizing fuel consumption. Through calibration, the spring facilitates accurate control over the fuel delivery process, adapting to varying operating conditions to maintain consistent performance.Attributes:• Spring rate of 13.68 newtons per millimeter.• The maximum solid length of the spring is 20.67 millimeters.• The direction of the coil is right-hand side.• Total coils are 6.89 in inch.• Active coils are 4.89 in inch.• Corrosion resistance.• Temperature resistance.• High tensile strength.Applications: The Fuel Ratio Control Spring is used in regulating the opening and closing of the fuel control valve within the equipment's engine, ensuring accurate fuel-air mixture control for optimal combustion efficiency.
