摘要： A system for inhibiting seizure of a bearing may include: a knocking sensor provided at one side of an engine to measure vibration transmitted from the engine and detect knocking of the engine, and a controller for controlling operation of the engine. In particular, the controller determines that a bearing of the engine is damaged when a magnitude of vibration of the engine inputted from the knocking sensor is greater than a damaged-bearing judging threshold value while the engine is operated in a damaged-bearing detecting region which is a region where knocking does not occur.

摘要： A method of preventing bearing seizure may include using at least one of a knock sensor, an engine oil pressure sensor, and a continuously variable valve timing (CVVT) system as a bearing seizure detection factor by a bearing controller, detecting damage of a bearing applied to an engine during operation of the engine in which a state of the bearing seizure detection factor is changed, and performing engine control using the bearing seizure detection factor when the bearing damage is detected.

摘要： A method of preventing bearing seizure may include using each of a knock sensor, an engine oil pressure sensor, and a continuously variable valve timing (CVVT) system as a bearing seizure detection factor by a bearing controller, detecting damage of a bearing applied to an engine during operation of the engine in which a state of the bearing seizure detection factor is changed, and performing engine control using the bearing seizure detection factor when the bearing damage is detected.

摘要： A knocking control method based on a separation learning range may include (a) designating a learning cell in a driving range represented by a load-rotating number, (b) dividing the learning cell into individual cells, (c) designating a knocking cell of a partial load and a knocking cell of a full load, respectively, as other cells; and (d) determining a reference of a spark timing advanced and lagged angle by a difference between a partial load learning value of a high load and a learning value in the full load and based on the determined reference, simultaneously performing a knocking cell learning of the partial load and a knocking cell learning of the full load or not performing the knocking cell learning of the full load at the time of performing the knocking cell learning of the partial load.
