• 1:Valve clearance: Adjust it to the standard value in a cold state. If it is too tight, it may overheat, and if it is too loose, it may cause air leakage and affect power.
• 2:Sealing: The fitting surface should be flat, and poor sealing may cause cylinder pressure drop and power attenuation. Regular inspection and grinding are necessary.
• 3:Cleanliness: Carbon buildup can cause valve blockage and hinder opening and closing. It is necessary to regularly clean the air passage and valve head.
• 4:Material adaptation: resistant to high temperature and high pressure, often made of alloy materials to avoid high-temperature deformation or fracture.
• 5:Installation timing: Align with the valve timing mark. Incorrect installation can easily damage the valves, pistons, and engine.
