摘要： A method of controlling an oil pump of a vehicle includes: acquiring, by a controller, information on an engine operating state or a driving condition detected by a driving information detection part; determining, by the controller, whether a predetermined condition of an alternate mode is satisfied on the basis of the acquired information on the engine operating state or the driving condition; and, when the condition of the alternate mode is satisfied, sequentially performing, by the controller, a high-pressure operation control that controls an operation of an oil pump system so as to an oil pressure of an engine to converge on a predetermined target high-pressure value and a low-pressure operation control that controls the oil pressure of the engine to converge on a predetermined target low-pressure value.

摘要： Methods and systems are provided for diagnosing variable oil pump degradation. In one example, a method may include cranking an engine with a motor and monitoring the motor current draw from a battery during cranking. The method may indicate degradation of a variable oil pump coupled to the engine by comparing the motor current draw with a baseline current level.

摘要： Disclosed herein is an oil supply device for an internal combustion engine, which includes a control unit that controls activation of an electric oil pump and that functions as either a reserve oil level estimator for estimating the level of oil reserved in auxiliary chambers or a reserve oil level detector for detecting the level of the oil reserved there. When it is estimated or detected that the level of the oil reserved in the auxiliary chambers has become equal to or less than a predetermined reserve oil level while the internal combustion engine is OFF, the control unit performs an oil replenishment control to replenish the auxiliary chambers with the oil by activating the electric oil pump.

摘要： A method and system of diagnosing a lubrication system of an engine includes determining a lubrication system fault and controlling an engine in response to the fault. The method is operative to first determine a poor state of health for a lubrication system, then determine an oil degradation or lube system fault. In response to a lube system fault, engine operation is altered in order to reduce the negative effects of the lube system fault such as increasing minimum idle speed in response to reduced oil pressure.

The lubricating oil passages include main lubricating oil passages. The main lubricating oil passages include communication portions linearly formed with extending portions. The communication portions communicate between the respective bearings of the crankshaft and the camshaft from outside the engine case. The extending portions extend from outside the engine case to the bearing of the camshaft. The relief device is disposed having a relief valve and a relief hole at the extending portions.

摘要： An internal combustion engine oil utilization system, comprising one or more oil pumps to receive and discharge engine oil including an engine oil circulation loop comprising a first flow path and a second flow path. The first flow path receives at least a portion of the oil discharged from the one or more oil pumps and utilizes the oil to lubricate the engine during running operation of the engine. The second flow path receives at least a portion of the oil discharged from the one or more oil pumps and accumulates the oil to start the engine and/or to lubricate the engine during at least one of a pre-starting operation and a starting operation of the engine.
