20140041384 | METHODS AND SYSTEM FOR CONTROLLING SURGE IN A TWO-STAGE TURBOCHARGER - Various methods and systems are provided for controlling air flow in a two-stage turbocharger. In one example, an engine method comprises adjusting one or more exhaust gas recirculation valves to maintain a first turbocharger within a first air flow range, and adjusting a turbocharger bypass valve to maintain a second turbocharger within a second air flow range. | 02-13-2014 |
20140047834 | METHODS AND SYSTEM FOR CONTROL OF A TWO-STAGE TURBOCHARGER - Various methods and systems are provided for regulating air flow through a two-stage turbocharger. In one embodiment, a method for an engine comprises, in response to a transient engine operating event, adjusting a provided amount of exhaust gas recirculation provided to an intake of the engine based on at least one of desired intake oxygen, one or more turbocharger conditions of a turbocharger, or a magnitude of the transient engine operating event. | 02-20-2014 |
20140067228 | METHODS AND SYSTEM FOR ENGINE OPERATION DURING DEGRADATION OF A TWO-STAGE TURBOCHARGER - Various methods and systems are provided for engine operation with a degraded turbocharger. In one embodiment, a method for an engine comprises reducing mass flow through a first turbocharger while continuing engine operation and adjusting operation of a second turbocharger in response to detected degradation of the first turbocharger. | 03-06-2014 |
20140067236 | METHODS AND SYSTEM TO PREVENT EXHAUST OVERHEATING - Various methods and systems are provided for lowering exhaust gas temperature. In one embodiment, a method comprises increasing an air-to-fuel ratio of an engine in response to an exhaust gas temperature exceeding a threshold temperature value to lower the exhaust gas temperature to a temperature below the threshold temperature value. | 03-06-2014 |
20140208739 | METHOD AND SYSTEM FOR EGR CONTROL FOR AMBIENT CONDITIONS - Various methods and systems are provided for adjusting a flow of exhaust gas in an exhaust gas recirculation system. In one embodiment, a method for an engine comprises controlling a flow of exhaust gas through an exhaust gas recirculation system of an engine system based on a choke level of a turbocharger. For example, the flow of exhaust gas in the exhaust gas recirculation system may be reduced to within a threshold of a choke level of the turbocharger, in response to an ambient condition. | 07-31-2014 |
20140214304 | METHODS FOR INTENTIONAL TURBO SURGING FOR ENHANCED SYSTEM CONTROL AND PROTECTIONS - Various methods and systems are provided for determining a surge level of a compressor. In one embodiment, a method for an engine comprises updating a stored estimate of a surge level of a compressor responsive to detection of a surge event. | 07-31-2014 |
20140336852 | SYSTEM AND METHOD FOR DETERMINING ENGINE FUEL LIMITS - A method of determining fuel limits for an engine includes measuring an actual fuel value for the engine and creating a plurality of engine speed points. The method further includes calculating respective static fuel limit points for each of the engine speed points utilizing the actual fuel value. The static fuel limit points define and limit a rated power of the engine. | 11-13-2014 |
