摘要： A method for sensing damage to a bearing of an engine using a vibration signal may sense the damage to the bearing even without a sensor for directly sensing the damage to the bearing using a frequency signal input to a knocking sensor from the engine for each traveling state (acceleration traveling, cruise traveling, deceleration traveling) of a vehicle.

摘要： The present disclosure relates to manufacturing oil gel capsules and adding the same to an overlay layer of a contact part for a vehicle. The present disclosure may provide a method for manufacturing oil gel capsules and a method for manufacturing a contact part for a vehicle, including the oil gel capsules. The oil gels in the oil gel capsules manufactured by the present disclosure may respond to the temperature environment of a contact part for a vehicle, and an aggregation phenomenon of gelators or an aggregation phenomenon of surfactants may not occur even after an oil is released. Therefore, as oil gel capsules are added to an overlay layer, the present disclosure may improve low friction characteristics and seizure resistance characteristics of a contact part for a vehicle without any side effects caused by the above-described aggregation phenomenon.

摘要： An oil gel capsule includes an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel. A contact part for a vehicle includes an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules including an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel.
