| Application No. | Application Title | Issue Date |
| 20080010037 | Reverse Rotation Detector For Internal Combustion Engine A crank angle sensor outputs a pulse signal whenever a crankshaft rotates a predetermined angle. An ECU performs an elimination process on a sequence of pulse signals to obtain a remaining signal used to determine the crank angle. When the rotation speed of the cranksha... | 01/10/2008 |
| 20070220960 | Method and apparatus for engine torque sensing An engine torque sensory system (10), adapted for use with an engine-driven vehicle (12) having a flexplate (18), including at least one sensor (26) fixedly attached on the surface of the flexplate (18) and operable to detect deformati... | 09/27/2007 |
| 20070180896 | METHOD AND AN ELECTRONIC CONTROL UNIT FOR DETERMINING THE DEGREE OF COOLING DURING NON-OPERATION OF AN INTERNAL COMBUSTION ENGINE The invention relates to a method for determining the degree of cooling during non-operation of an internal combustion engine. Fuel temperature characteristics at and following an engine start are determined, and the degree of cooling during non-operation of the engine ... | 08/09/2007 |
| 20060174700 | Integrated multisensor An integrated multisensor, in particular for use in an internal combustion engine of a motor vehicle is provided. The multisensor includes at least one pressure/temperature sensor, at least one magnetic field sensor, and a plurality of insulating wells, wherein a separa... | 08/10/2006 |
| 20050210969 | Engine cylinder deactivation test apparatus and method for using An apparatus is provided for testing functionality of an engine cylinder deactivation control and system having a plurality of solenoid-operated valves for controlling hydraulic actuation of switching valve lifters. The apparatus includes a portable test box enclosing a... | 09/29/2005 |
| 20050092074 | Method and apparatus for use with a fluid filter A fluid pressure near a filter (103) is measured and compared (307) to a predetermined value that is based on one or more engine operating parameters. When the measured fluid pressure deviates enough from the predetermined value by an established amount, a... | 05/05/2005 |
| 20050066715 | Method of estimating engine cooling fan power losses A method for estimating engine torque loss due to a fan. A table of maximum fan torque losses is compiled at a plurality of engine speeds. An engine control unit (ECU) is configured with the table of maximum fan torque losses. A first maximum fan torque loss and a secon... | 03/31/2005 |
