| 20120046886 | MASS-AIRFLOW MEASUREMENT CONVERSION APPARATUS FOR INTERNAL COMBUSTION ENGINE CARBURETORS - A mass-airflow measurement conversion apparatus for internal combustion engine carburetors includes a plurality of pressure sensors disposed at different location along an air intake path of an internal combustion engine, each sensor adapted to sense a pressure of air flowing into the internal combustion engine and output an electrical signal as a pressure signal corresponding to the sensed air pressure; and a calculation section which receives the pressure signals and generates a mass air flow signal as an output signal based on the received pressure signals. | 02-23-2012 |
| 20110218726 | UEGO SENSOR AIR-FUEL RATIO DETERMINATION SYSTEM AND METHOD - A method of determining an air-fuel ratio of an internal combustion engine in real-time includes: calibrating sensitivity of a universal exhaust gas oxygen sensor to a plurality of gases; inputting to a universal exhaust gas oxygen sensor controller a molecular composition of Hydrogen, Carbon, Oxygen, and Nitrogen which comprise a combustion fuel in use in the internal combustion engine; calculating with the universal exhaust gas oxygen sensor controller an air-to-fuel ratio by performing a chemical balance equation calculation based on the universal exhaust gas oxygen sensor sensitivity calibration and the input combustion fuel molecular composition; and transmitting the calculated air-to-fuel ratio to an engine control unit in real-time. | 09-08-2011 |
| 20100263439 | ENGINE POSITION TRACKING FOR INTERNAL COMBUSTION ENGINES - A method for determining engine crankshaft position determines the position of a rotating crankshaft using one or many crankshaft position sensors. The sensor output signals representing crankshaft position are digitized and specific timing positions are derived. The sampled timing positions are compared to a known position template to determine crankshaft position. | 10-21-2010 |
| 20100126260 | MANIFOLD PRESSURE DETERMINATION DEVICE - A pressure measurement system includes a multiplexer unit which inputs a plurality of electrical signals representative of pressures, and a comparison unit which compares the electrical signals among each other to determine a specified signal characteristic, wherein the multiplexer unit selects one of the electrical signals as an output signal based on the determination of the specified signal characteristic, and outputs the selected signal. | 05-27-2010 |
| 20080245142 | ENGINE POSITION TRACKING FOR INTERNAL COMBUSTION ENGINES - A method for determining engine crankshaft position determines the position of a rotating crankshaft using one or many crankshaft position sensors. The sensor output signals representing crankshaft position are digitized and specific timing positions are derived. The sampled timing positions are compared to a known position template to determine crankshaft position. | 10-09-2008 |
