176-3138: ВСТАВКА ВЫХЛОП

An Exhaust Valve Seat Insert is a metallic ring-shaped component installed in the cylinder head of an internal combustion engine. Its purpose is to create a durable and heat-resistant surface against which the exhaust valve can seal during the combustion process. This seating surface ensures proper sealing to prevent exhaust gases from escaping into the cylinder during combustion and from contaminating the engine oil. The primary function of an exhaust valve seat insert provides a durable, heat-resistant, and wear-resistant seating surface for the exhaust valve. It withstands the extreme heat and pressure generated during the combustion process, maintaining an effective seal between the exhaust valve and the cylinder head. This seal is required for engine efficiency, performance, and emissions control.

Attributes:
• Designed to withstand high temperatures generated during combustion without deforming or losing sealing properties.
• Designed to endure the constant impact and friction from the exhaust valve.
• Manufactured with tight tolerances to ensure proper fitment and sealing within the cylinder head.

Applications:
An Exhaust Valve Seat Insert is located within the cylinder head assembly. Each cylinder in the engine has its exhaust valve seat insert positioned to form a seal with the corresponding exhaust valve. These inserts are integral components of the engine's combustion chamber, contributing to its overall efficiency, reliability, and longevity.
