An ignition spark plug is a crucial component in the internal combustion engine of a vehicle. It plays a key role in starting the engine and ensuring it runs smoothly. Without a functioning spark plug, the engine would not be able to ignite the air-fuel mixture, resulting in the vehicle being unable to start.
The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.
When it comes to the 2.0% TSI engine, the valve cover gasket must meet specific requirements to ensure optimal performance. The gasket must be made from high-quality materials that can withstand the high temperatures and pressures inside the engine. It must also be designed to provide a tight seal to prevent oil leaks and maintain proper lubrication.
