20110132325 | SYSTEM AND METHOD FOR REDUCING PARTICULATE MATTER PRODUCED BY AN ENGINE - A method for reducing particulate matter emitted by an engine is disclosed. In one example, the start of fuel injection timing is adjusted in response to a change in engine operating conditions. In particular, start of injection timing may be advanced and then retarded to promote fuel vaporization. | 06-09-2011 |
20110184629 | FUEL-BASED INJECTION CONTROL - Systems and methods of operating an engine with a varying fuel composition. In one example, a split injection is performed during engine cranking with at least some fuel injected in the intake stroke and some fuel injected in the compression stroke. Further, a split ratio of the injection is adjusted based on the alcohol content of the injected fuel. | 07-28-2011 |
20120324864 | SYSTEM AND METHODS FOR CONTROLLING AIR FUEL RATIO - Methods and system for controlling air-fuel ratios in an internal combustion engine are disclosed. One embodiment comprises, adjusting a sensor calibration correction value of an exhaust sensor upstream of a catalyst based on an exhaust sensor downstream of the catalyst. The adjustment of the sensor calibration correction value takes advantage of the fact that certain aromatic hydrocarbons causing errors in the reading of the upstream sensor are not present at the downstream sensor due to sufficient catalytic activity of a catalyst positioned between the sensors. | 12-27-2012 |
20130253803 | FUEL-BASED INJECTION CONTROL - Systems and methods of operating an engine with a varying fuel composition. In one example, a split injection is performed during engine cranking with at least some fuel injected in the intake stroke and some fuel injected in the compression stroke. Further, a split ratio of the injection is adjusted based on the alcohol content of the injected fuel. | 09-26-2013 |
20130340718 | DIRECT INJECTION EVENT-BASED ENGINE STARTING - A method for starting an internal combustion engine having direct fuel injection, comprising of adjusting a number of direct injections per combustion cycle based on a cylinder event number from a first cylinder event. | 12-26-2013 |
20140137837 | DIRECT INJECTION EVENT-BASED ENGINE STARTING - A method for starting an internal combustion engine having direct fuel injection, comprising of adjusting a number of direct injections per combustion cycle based on a cylinder event number from a first cylinder event. | 05-22-2014 |
20140172275 | METHOD AND SYSTEM FOR ENGINE CONTROL - Methods and systems are provided for controlling exhaust emissions by adjusting an injection profile for fuel injected into an engine cylinder from a plurality of fuel injectors during engine start and crank. By splitting injection of fuel during start so that a portion of fuel is port injected and a remaining portion is direct injected as one or multiple injections, the soot load of the engine can be reduced and fuel economy can be improved. | 06-19-2014 |
20140297159 | METHOD AND SYSTEM FOR ENGINE CONTROL - Methods and systems are provided for controlling exhaust emissions by adjusting an injection profile for different fuels injected into an engine cylinder from different fuel injectors during engine start and crank. By splitting fuel injection during start and cranking so that fuel of lower alcohol content is port injected and fuel of higher alcohol content is direct injected as one or multiple injections, the soot load of the engine can be reduced and fuel economy can be improved. | 10-02-2014 |
20140297162 | METHOD AND SYSTEM FOR ENGINE CONTROL - Methods and systems are provided for controlling exhaust emissions by adjusting an injection profile for fuel injected into an engine cylinder from a plurality of fuel injectors during engine start and crank. By splitting injection of fuel during start so that a portion of fuel is port injected and a remaining portion is direct injected as one or multiple injections, the soot load of the engine can be reduced and fuel economy can be improved. The injections are adjusted based on the alcohol content of the injected fuel to take advantage of the charge cooling properties of the fuel. | 10-02-2014 |
20140318498 | SYSTEM AND METHOD FOR INJECTOR COKING DIAGNOSTICS AND MITIGATION - A system and method for compensating for, or alleviating accumulation of, coking residues on fuel injectors is disclosed. The method includes adjusting an engine operating parameter based on a shift in a fuel injector current profile during an initial current rise of injector activation. | 10-30-2014 |
20150240737 | METHOD FOR FUEL INJECTION CONTROL - Methods and systems are described for controlling fuel injection in an engine equipped with a dual injector system including a port injector and a direct injector. A ratio of port injected fuel to direct injected fuel is adjusted based at least on intake valve temperature. The proportion of fuel port injected into a cylinder is increased as the intake valve temperature for the given cylinder increases to improve fuel vaporization in the intake port. | 08-27-2015 |
