How to distinguish between intake and exhaust valve springs for EA888?

[DawsonDella]

ea888 intake and exhaust valve springs can be distinguished by the fact that the intake spring is slightly thicker and less dense than the exhaust spring. Below is relevant information about EA888 valve springs: 1. Production and Function: Valve springs are small tools that ensure the timely seating and tight sealing of valves, preventing valve bounce during engine vibration which could compromise sealing. Valve springs are typically made from high-quality alloy steel wire and undergo heat treatment to enhance fatigue strength. 2. Usage and Maintenance: To prevent corrosion, the surface of the spring should be galvanized or phosphated. Both ends of the spring must be ground flat and perpendicular to the spring axis to prevent tilting during operation. 3. Working Principle: When the operating frequency of the valve spring matches its natural frequency or an integer multiple thereof, resonance occurs, increasing the likelihood of breakage. To prevent resonance, variable pitch springs are used, and most engines now employ concentrically mounted dual springs.
