Air Intake / Exhaust Valve

288MW Engine Intake & Exhaust Valve Set

🔧 Intake Valve · Exhaust Valve · Valve Train Components

For 288MW type engine · OEM specification replacement · Set includes 3 intake + 3 exhaust valves

This is a brand new replacement intake and exhaust valve set for the 288MW type engine. Valves are core components of the engine's valve train, controlling intake and exhaust flow, directly affecting engine power output, fuel economy, and operational stability.

This set includes 3 intake valves and 3 exhaust valves, manufactured from quality materials to OEM specifications, ensuring perfect fit with the original valve seats for reliable sealing and durability. It is an ideal replacement when original valves are worn, burned, or have poor sealing.

This intake and exhaust valve set fits the following engines:

Intake and exhaust valves are core components of the engine's valve train, directly affecting engine performance:

• Intake Valve: Controls the entry of fresh air-fuel mixture into the cylinder. Its opening timing and sealing directly affect intake efficiency and combustion quality.
• Exhaust Valve: Controls the expulsion of burned gases from the cylinder. Its condition affects exhaust efficiency and the next cycle's intake quality.
• Sealing Performance: The sealing between valves and valve seats directly affects cylinder compression pressure and combustion chamber sealing, impacting power output.
• Heat Dissipation: Exhaust valves operate at high temperatures, transferring heat through the valve seat. Good contact aids in heat dissipation.

• Loss of Power: Engine feels underpowered, sluggish acceleration.
• Rough Idle: Engine vibrates at idle, unstable RPM.
• Hard Starting: Difficult to start cold or hot.
• Increased Fuel Consumption: Poor valve sealing causes incomplete combustion, higher fuel usage.
• Exhaust Smoke: Poor sealing may allow oil into combustion chamber or cause black smoke from incomplete combustion.
• Valve Noise: Excessive valve clearance or wear causes tapping or clicking sounds.
• Low Cylinder Compression: Compression test readings below specifications.

If you experience these symptoms, inspect the valves and replace if necessary.

• OEM Specifications: Manufactured to 288MW engine specifications for perfect fit.
• Quality Materials: Made from high-temperature, wear-resistant alloy steel with excellent heat and corrosion resistance.
• Precision Machining: Precision ground valve stems and accurate valve face angles for proper sealing with valve seats.
• Complete Set: Includes all 3 intake valves and 3 exhaust valves for complete replacement.
• Direct Replacement: Perfect substitute for worn or damaged original valves (Part numbers C90036030000, C90036031000).

🔧 Installation Tip

1. Replacing valves requires removing the cylinder head – professional installation is recommended.
2. Before installation, inspect valve guides for wear; replace if necessary.
3. After installing new valves, perform valve lapping or check sealing with the valve seats.
4. Adjust valve clearance to OEM specifications after installation.
5. It is recommended to replace valve stem seals at the same time for proper sealing.
6. Check valve sealing after assembly before installing on the vehicle.

⚠️ Important Notice: This is a 288MW engine intake and exhaust valve set, including 3 intake valves (Part No. C90036030000) and 3 exhaust valves (Part No. C90036031000). Suitable for 2022-2024 288MW type 3-cylinder engines. Valves are critical engine components; replacement requires proper mechanical skills. Before purchasing, please verify your engine model.
