20140261342 | Apparatus, System, and Method for Reducing Emission of Nitrogen Oxides - An apparatus, system and method for reducing the emission of nitrogen oxides in an internal combustion engine system. Exhaust gas directly or indirectly downstream of the internal combustion engine is at least selectively stored in an exhaust gas storage region. Upon the occurrence of at least one enablement condition, indicative of a potential period where the emission of nitrogen oxides (NOx) will increase, the stored exhaust gas is inserted into the internal combustion engine to assist in reducing the emission of the nitrogen oxides. The exhaust gas storage volume regularly, or the exhaust gas storage volume may be filled during strategic periods when the emissions of nitrogen oxides are low and/or there is a low need for the recirculation of exhaust gas. | 09-18-2014 |
20140278017 | APPARATUS, SYSTEM, AND METHOD FOR REDUCING ENGINE KNOCK - A system and method for reducing engine knock associated with an internal combustion engine. An exhaust gas recirculation sub-system is fluidly connected to the internal combustion engine and includes a compressor and an exhaust gas storage tank fluidly connected to the compressor. In response to measuring that engine knock is occurring, compressed exhaust gas is injected from the exhaust gas storage tank into a combustion chamber of the internal combustion engine. | 09-18-2014 |
20150330503 | INTEGRATED POWERTRAIN SYSTEM - A system for a vehicle includes a powertrain system including an engine, a transmission, a drive shaft, and a final drive; and a controller communicably coupled to the powertrain system. The controller is structured to: receive a shift schedule for the transmission of a vehicle, the shift schedule indicating when shift events occur based on operation of the vehicle; receive vehicle operation data during operation of the vehicle, the vehicle operation data including a current combustion recipe for the engine; determine a predicted impact of a scheduled shift event on a fuel consumption rate of the vehicle based on the current combustion recipe for the engine; determine an adjustment to the scheduled shift event based on the predicted impact; and provide a command to implement the adjustment to the scheduled shift event to the transmission of the vehicle. | 11-19-2015 |

20140352656 | INTAKE PORT THROTTLING CONTROL FOR DUAL FUEL ENGINES WITH ASYMMETRIC INTAKE PASSAGES - Systems and methods for controlling intake flow to dual fuel internal combustion engines are disclosed. The system includes an intake system for providing a charge flow to a plurality of cylinders of the engine through at least two asymmetric intake passages connected to respective intake ports of each cylinder of the engine. At least one or both intake passages includes a throttle to control the intake flow therethrough. The characteristics of the charge flow into the cylinders is controlled by the throttles in response to operating conditions of the dual fuel engine. | 12-04-2014 |
20150113964 | SYSTEMS AND METHODS FOR CONTROL OF ENGINE NOX EMISSIONS USING LIQUID AND DRY REDUCTANT SOURCES - Reductant delivery systems are disclosed that include a dry reductant source and a liquid reductant source which are operable to selectively provide gaseous reductant and liquid reductant to an exhaust aftertreatment system for treatment and reduction of NOx emissions. The gaseous reductant is provided to the exhaust aftertreatment system for treatment of NOx emissions under a first temperature condition associated with the exhaust system and the liquid reductant for treatment of NOx emissions under a second temperature condition associated with the exhaust system. | 04-30-2015 |
20150128587 | SYSTEM AND METHOD FOR REDUCING ENGINE KNOCK - A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value. | 05-14-2015 |
20150219023 | FUEL SELECTION SYSTEM AND METHOD FOR DUAL FUEL ENGINES - Systems and methods for controlling operation of dual fuel internal combustion engines are disclosed. The control techniques provide for override of a dual fuel mode of operation of the engine by selection of a diesel only fuelling mode in response to one or more operating conditions of the internal combustion engine. | 08-06-2015 |
20150219027 | CYLINDER PRESSURE BASED CONTROL OF DUAL FUEL ENGINES - Systems and methods for controlling operation of dual fuel internal combustion engines in response to cylinder pressure based determinations are disclosed. The techniques control fuelling contributions from a first fuel source and a second fuel source to achieve desired operational outcomes in response to the cylinder pressure based determinations. | 08-06-2015 |
