20120204542 | MULTI-LEG EXHAUST AFTERTREATMENT SYSTEM AND METHOD - An exhaust aftertreatment system for treating exhaust flow from an internal combustion engine, and associated method, allows for independent control of exhaust flow through plural exhaust legs of the exhaust aftertreatment system. The independent control of exhaust flow is carried out by adjusting a valve positioned in each the exhaust legs based on a value of a signal generated by a flow measurement device positioned along at least one of the exhaust legs. The valves can be adjusted to force a target flow in a exhaust leg, relative flow among exhaust legs, exhaust temperature in an exhaust leg, exhaust backpressure and/or imbalance within the exhaust legs. | 08-16-2012 |
20140373822 | SYSTEM AND METHOD FOR A SELF-ADJUSTING DUAL FUEL GAS CONTROL - This disclosure provides a system and method that eliminates the need for manually calibrating or adjusting a dual fuel internal combustion engine to compensate for variations in composition of a gaseous fuel or other variations, such as ambient or site conditions. The system and method functions by determining an engine load, determining an advantageous gaseous fuel substitution rate from the engine load and speed in addition to an actual gaseous fuel substitution rate, modifying the advantageous gaseous fuel substitution rate by a minimum liquid fuel flow rate, engine protection parameters, and oxidation catalyst protection parameters, and then determining an error term in response to the modified advantageous gaseous fuel substitution rate and the actual gaseous fuel substitution rate. The error term is used to adjust a gaseous fuel control valve. | 12-25-2014 |

20130139788 | FUEL DRIFT ESTIMATION AND COMPENSATION FOR OPERATION OF AN INTERNAL COMBUSTION ENGINE - Methods and systems are disclosed for fuel drift estimation and compensation using exhaust oxygen levels and fresh air flow measurements. An actual fueling to the engine cylinders is determined from the exhaust oxygen level and fresh air flow to the internal combustion engine. The actual fueling is compared to an expected fueling based on the fueling command provided to the internal combustion engine. The difference between the actual fueling and expected fueling is fuel drift error attributed to changes or drift in the fuel injection system and is used to correct or compensate future fueling commands for the fuel drift. | 06-06-2013 |
20130232952 | SYSTEMS AND METHODS USING INTERNAL EGR FOR AFTERTREATMENT SYSTEM CONTROL - An internal combustion engine system includes: an engine with a plurality of pistons housed in respective ones of a plurality of cylinders; an air intake system to provide air to the plurality of cylinders through respective ones of a plurality of intake valves; an exhaust system to release exhaust gas from the plurality of cylinders through respective one of a plurality of exhaust valves; an aftertreatment system to treat exhaust emission from the engine; at least one sensor to provide a sensor signal corresponding to an efficiency of the aftertreatment system; and a controller coupled to the at least one sensor and operable to regulate an internal exhaust gas recirculation operation in the cylinders when the aftertreatment system operates at less than a desired efficiency. | 09-12-2013 |

20090089941 | Process for Creating Composite Materials to Produce Polymer Nanocomposite Films that Exhibit Improved Light Fastness Properties - The present invention relates to new methods of producing polymer composite materials. More specifically, the invention involves a process in which layered materials including clays and other inorganic materials are dispersed into polymer systems to create polymer nanocomposite films. The resulting films exhibit improved resistance to fading when compared to polymer films that lack the additional layered materials. | 04-09-2009 |
