Womala Engine Exhaust Valve 32249029 Exhaust Valve for Volvo XC90 Engine Auto Parts

Core Functions

• Exhaust Gas Discharge: Opens at the end of the power stroke to allow burned exhaust gases to flow from the combustion chamber into the exhaust manifold. This clears the chamber for the next intake stroke, avoiding residual gas buildup that would reduce engine efficiency.
• Sealing the Combustion Chamber: Closes tightly against the valve seat during the intake, compression, and power strokes. This prevents exhaust gases from leaking back into the chamber (which would lower compression pressure and power) and keeps fresh air-fuel mixture from escaping into the exhaust (which would increase fuel consumption and emissions).
• High-Temperature Resistance: Maintains structural integrity under extreme heat from combustion, avoiding warping, cracking, or erosion that would disrupt valve operation and require premature replacement.

Notes: Exhaust valves are cylinder-specific and may differ in size or material based on the engine variant (e.g., 2.0L turbo vs. 3.0L supercharged) even for the same model. For 100% fitment accuracy, confirm the exact cylinder position (e.g., cylinder 1–6) and engine displacement this valve corresponds to, and verify compatibility via your vehicle’s VIN (Vehicle Identification Number) or consult Volvo’s official service manual.
