The 100261 Valve Cone: A Key Engine Component

The 100261 valve cone is a critical part within an internal combustion engine's valvetrain. Its primary function is to form a perfect seal against the valve seat when closed. This action is essential for:

Containing Compression: Sealing the combustion chamber during the compression and power strokes.

Ensuring Proper Intake: Allowing the precise intake of the air-fuel mixture.

Facilitating Exhaust: Enabling the complete expulsion of exhaust gases.

How It Works & Use:

The valve cone is the angled, disc-shaped head of the valve stem. It is used in conjunction with a matching valve seat in the cylinder head. The valve spring forces the cone against the seat to close it. During engine operation, the camshaft lifts the valve, moving the cone away from the seat to open the passage. Its precise angle and perfectly machined surface are crucial for a leak-proof seal, directly impacting engine performance, efficiency, and emissions.

In summary, the 100261 valve cone is a fundamental sealing component. Its proper operation ensures the engine can breathe correctly and generate power efficiently, making it vital for smooth and reliable engine performance.
