Internal-combustion Engines > Charge Forming Device (e.g., Pollution Control) > Including Exhaust Gas Condition Responsive Means > Combined With Engine Condition Responsive Means Combined With Engine Condition Responsive MeansCombined With Engine Condition Responsive Means patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.07/12/07 - 20070157912 - Process for use with dual-fuel systems A system and method is provided for use with a duel-fuel fumigation system. The system injects a gaseous-fuel flow into the air intake stream of a diesel engine. As presented, the system is operative to meter the gaseous-fuel flow into the diesel engine based on one or more engine parameters ... 06/07/07 - 20070125350 - Air-fuel ratio control apparatus An air-fuel ratio control apparatus is applied to an internal combustion engine including a variable lift mechanism wich changes a lift amount of an intake valve. An oxygen sensor, wich outputs a signal indicating an oxygen concentration in exhaust gas, is provided downstream of an exhaust gas purification catalyst in ... 06/07/07 - 20070125349 - System and method for performing a particulate sensor diagnostic An apparatus comprising an internal combustion engine, an exhaust system in communication with the engine, a particulate sensor associated with the exhaust system, and a controller in electrical communication with the particulate sensor, wherein the controller is configured to determine a change in a rate of exhaust flow in the ... 05/10/07 - 20070101977 - Method and system for using a measure of fueling rate in the air side control of an engine Methods and systems for using a measure of fueling rate in the air side control of an engine. By using a measure of the fueling rate, the air side control may, for example, anticipate the future air side needs of the engine, and adjust one or more air side parameters ... 04/05/07 - 20070074710 - Fuel supply control system for internal combustion engine A fuel supply control system for an internal combustion engine having at least one fuel injection valve for injecting fuel into an intake pipe or a combustion chamber of the engine. A flow rate of air supplied to the engine and an air-fuel ratio are detected. A demand fuel injection ... 04/05/07 - 20070074709 - Controller and control method for internal combustion engine A controller approximates an output characteristic of an air flow meter using at least one parameter, and approximates a characteristic of a fuel injection characteristic of an injector using at least one parameter. These parameters are determined and updated based on an exhaust air-fuel ratio acquired by an air-fuel ratio ... 03/22/07 - 20070062504 - Method and device for controlling an internal combustion engine A method and device for controlling an internal combustion engine are provided. A first quantity characterizing the actually injected fuel amount and a second quantity characterizing the desired amount of fuel to be injected are determined on the basis of performance characteristics. The first quantity is compared to the second ... 07/13/06 - 20060150962 - Air-fuel ratio feedback control apparatus for engines An air-fuel ratio setting section sets a target air-fuel ratio KCMD according to the conditions of an engine. An air-fuel ratio correction coefficient calculating section calculates an air-fuel ratio correction coefficient KAF for controlling the air-fuel ratio wherein a detected air-fuel ratio KACT detected by a LAF sensor is converged ... 07/06/06 - 20060144378 - Multi-cylinder internal combustion engine and method for the individual shutdown and restart of its cylinders In a method for the individual shutdown and restart of cylinders of a multi-cylinder internal combustion engine having at least one intake and one exhaust valve per cylinder, a variable valve control, and a fuel injection system, according to the requirement of its shutdown, a deactivateable cylinder is filled with ... 09/08/05 - 20050193996 - Method and device for controlling an internal combustion engine A device and a method for controlling an internal combustion engine in which, starting from the comparison between a measured and an expected value for a lambda signal, a correction value is specified for a fuel signal characterizing the fuel quantity, or an air signal characterizing the air quantity.
