Knock sensors detect engine knocking or pinging, a phenomenon caused by premature combustion. By monitoring these vibrations, the ECU can adjust ignition timing to prevent knocking, enhancing engine performance and longevity.
Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.

Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
