摘要： An internal combustion engine, a method of operating the internal combustion engine, and a controller are disclosed. The method may comprise measuring a first pressure at a first position in a fluid line containing pressurized fluid; comparing the first pressure to a first threshold; in response to the first pressure exceeding the first threshold, transmitting a signal to depressurize the fluid line; after transmitting the signal to depressurize the fluid line, measuring a second pressure in the fluid line and comparing the second pressure to at least one of a second threshold and a third threshold, the second threshold being greater than the third threshold and less than the first threshold; and in response to the second pressure being less than the second threshold and exceeding the third threshold, transmitting another signal to depressurize the fluid line.

摘要： A method of operating an engine includes starting and stopping operation of an internal combustion engine that includes a crankshaft having a bearing journal and a bearing in which the bearing journal is rotatable. The crankshaft is constantly turned when the internal combustion engine is in the non-fueled mode. An oil pump can be driven to lubricate the bearing journal and the bearing while the internal combustion engine is in the non-fueled mode to provide hydrodynamic lubrication. An engine is also disclosed.

摘要： The present invention is a method and apparatus for controlling driving of the electric oil pump. The method includes the steps of deciding whether a predetermined time has elapsed after oil supply to the hydraulic chain tensioner has stopped, deciding whether an engine start prediction signal is inputted to a controller, and driving the electric oil pump to supply oil to the hydraulic tensioner when the engine start prediction signal is inputted. The present invention insures that oil pressure is maintained in the chamber of the hydraulic tensioner before cranking of the engine, thereby preventing oscillation of the chain and tensioner piston at the time of engine start up.
摘要翻译：本发明是用于控制电动油泵的驱动的方法和装置。该方法包括以下步骤：确定在向液压链条张紧器供油之后是否已经经过了预定时间，确定发动机起动预测信号是否被输入到控制器，以及驱动电动油泵向液压张紧器供油当输入发动机起动预测信号时。本发明确保在发动机起动之前在液压张紧器的腔室内保持油压，从而防止发动机起动时链条和张紧器活塞的振动。

摘要： In a system for pre-lubrication of an internal combustion engine of a vehicle having an oil reservoir and at least one oil passageway or galley in communication with an exterior of the engine, there is provided a fluid circuit, external to the engine, including a first conduit having an inlet and an outlet, the inlet in fluid communication with an output of the oil reservoir. The fluid circuit also includes an auxiliary oil hydraulic pump, including a pump motor having an inlet and an outlet, the inlet in fluid communication with the outlet of the first conduit. The fluid circuit also includes a second conduit having an inlet and an outlet, the inlet in fluid communication with the outlet of the pump, the outlet in fluid communication with the engine oil passageway and galleys. The fluid circuit also includes switches and timers for selectably actuating the motor of the oil pump for selectable periods of time prior to, and/or after, ignition. Further included is a valve for selectably closing the outlet of the second conduit at or upstream of the inlet to the engine oil passageway, in which the valve is normally-open.

摘要： A lubricating arrangement for an I.C. engine in which at least one lubricating pump for engine lubrication is activated by a battery-fed electric motor, independent of the I.C. engine, which supplies a preset oil quantity which is unrelated to the rpms of the I.C. engine. As this lubricating pump is driven by a battery-fed electric motor which runs up within a fraction of a second, the I.C. engine is instantly under pressure with a full quantity of lubricating oil.
