20090031970 | SWITCHABLE VALVETRAIN SYSTEM AND METHOD OF OPERATION - A switchable valvetrain system is provided having a control unit and a pressure regulator valve responsive to control signals from the control unit. A pressurized fluid source is provided in communication with the pressure regulator valve. A switchable valvetrain component having a latching mechanism and lubrication circuit in selective communication with the pressurized fluid source through the pressure regulator valve is also provided. The pressure regulator valve is operable to selectively and variably communicate fluid pressure from the pressurized fluid source to the latching mechanism and the lubrication circuit in response to control signals from the control unit. A method of operating the switchable valvetrain system is also provided. | 02-05-2009 |
20100012410 | Cloud Point Monitoring Systems for Determining a Cloud Point Temperature of Diesel Fuel - Cloud point monitoring systems for determining a cloud point temperature value for diesel fuel are provided. In one exemplary embodiment, a cloud point monitoring system receives diesel fuel in the tubular conduit and propagates light through the diesel fuel. The cloud point monitoring system further determines a cloud point temperature value indicative of a cloud point of the diesel fuel based on a light intensity level of the light that has propagated through cooled diesel fuel. | 01-21-2010 |
20100186694 | ENGINE INCLUDING CYLINDER DEACTIVATION ASSEMBLY AND METHOD OF CONTROL - A method is provided for operating an engine assembly having a hydraulically actuated component. The method may include providing pressurized oil from a pressurized oil source to an oil passage in communication with the hydraulically actuated component and determining a first oil pressure measurement within the oil passage a first predetermined time after the providing. The method may further include preventing operation of the hydraulically actuated component when the first oil pressure measurement is below a first predetermined limit, isolating the oil passage from the pressurized oil source after the providing, and determining a second oil pressure measurement within the oil passage a second predetermined time after the isolating when the first oil pressure measurement is above the first predetermined limit. Operation of the hydraulically actuated component may be prevented when the second oil pressure measurement is above a second predetermined limit. | 07-29-2010 |
20100186701 | ENGINE INCLUDING CYLINDER DEACTIVATION ASSEMBLY AND METHOD OF CONTROL - A method of purging air from an oil passage in communication with a lifter assembly in an engine assembly may include isolating the oil passage from a pressurized oil source while the lifter assembly is engaged with a base region of a cam lobe to operate the first lifter assembly in the activated mode. The pressurized oil may be provided to the lifter assembly via the oil passage after the isolating when the lifter assembly is engaged with a lift region of the cam lobe. The lifter assembly may be maintained in the activated mode after the providing. Air may be purged from the oil passage based on the pressurized oil provided to the oil passage. | 07-29-2010 |
20100274570 | VEHICLE CHARGING AUTHORIZATION - Methods and apparatus are provided for charging an onboard energy storage system of a plug-in vehicle using a charging station. An embodiment of the system includes a vehicle communication system configured to transmit data related to charging authorization to the charging station. The embodiment also includes an electronic device configured to communicate with the vehicle communication system within a set range from the plug-in vehicle; and a vehicle controller communicatively coupled to the vehicle communication system. The vehicle controller is configured to direct the vehicle communication system to transmit the data related to charging authorization if the electronic device is within the set range from the plug-in vehicle. | 10-28-2010 |
20110040471 | ROAD GRADE COORDINATED ENGINE CONTROL SYSTEMS - An engine control system of a vehicle includes a road grade module and a predictive control module. The road grade module detects a grade of a road that is ahead of the vehicle. The predictive control module detects that a first cylinder of an engine of the vehicle is deactivated while a second cylinder of the engine is activated. The predictive control module activates the first cylinder based on the grade. | 02-17-2011 |
20110060497 | BIODIESEL DATA COLLECTION SYSTEM - A vehicle biodiesel fuel diagnostic method may include determining a biodiesel fuel concentration of fuel added to a vehicle fuel tank during a fueling event at a fueling location and determining the fueling location. The biodiesel fuel concentration and fueling location may be transmitted to an information system where the concentration and location are stored in a database. The method may further include indicating an abnormal biodiesel fuel condition in the database when the biodiesel fuel concentration is outside of a predetermined range. | 03-10-2011 |
20150354419 | OIL PUMP CONTROL SYSTEMS AND METHODS - A first target module determines a first target output pressure of an engine oil pump based on a speed of the engine oil pump and an oil temperature. A second target module, based on a runtime period of an engine, sets a second target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A third target module, based on an engine load, sets a third target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A selection module selects one of the second and third target output pressures, sets a selected target output pressure based on the selected one of the second and third target output pressures, and controls displacement of the engine oil pump based on the selected target output pressure. | 12-10-2015 |
