Patent number: 11072355Abstract: Various methods and systems are provided for detecting surge of a turbocharger during engine operation. As one example, a system includes an engine coupled to a low pressure turbocharger and a high pressure turbocharger; and a controller with non-transitory instructions stored in memory that when executed during operation of the engine cause the controller to: indicate an occurrence of surge of the high pressure turbocharger in response to a deviation of a modeled speed of the high pressure turbocharger from a measured speed of the high pressure turbocharger by a threshold amount, where the modeled speed tracks the measured speed during non-surge conditions, as engine operating conditions change.Type: GrantFiled: November 15, 2018Date of Patent: July 27, 2021Assignee: TRANSPORTATION IP HOLDINGS, LLCInventors: Michael Mangus, James Robert Mischler, Samuel Lyle Hazen

Patent number: 10794304Abstract: Various methods and systems are provided for estimating fresh intake air flow. In one example, a system comprises an engine having an intake manifold to receive fresh intake air and an exhaust gas recirculation (EGR) system to supply EGR to the intake manifold, where flow of EGR through the EGR system is controlled by one or more exhaust valves. The system further includes a controller configured to adjust a position of the one or more exhaust valves based on an estimated fresh intake air flow rate, where during a first set of operating conditions, the fresh intake air flow rate is estimated based on a total gas flow rate into the engine and further based on a current position of the one or more exhaust valves, intake manifold pressure, air-fuel ratio, and fuel flow to one or more cylinders of the engine.Type: GrantFiled: March 30, 2018Date of Patent: October 6, 2020Assignee: TRANSPORTATION IP HOLDINGS, LLCInventors: Luke Michael Henry, James Robert Mischler, David Zielinski, Samuel Lyle Hazen, Ralph Wheeland

Patent number: 9702297Abstract: Various methods and systems are provided for adjusting a turbine boost control actuator based on a single common reference value. In one example, a method for an engine includes adjusting a turbine boost control actuator to control an intake manifold pressure to a limit, the limit based at least in part on one or more of peak cylinder pressure, turbine speed, and a pressure difference across a turbine.Type: GrantFiled: October 6, 2014Date of Patent: July 11, 2017Assignee: General Electric CompanyInventors: Luke Michael Henry, James Robert Mischler, Samuel Lyle Hazen

Patent number: 6813583Abstract: A system and method for estimating the wheel speed of a vehicle propelled by DC motors mechanically coupled to at least one wheel on the vehicle so as to rotate said one or more wheel. At least one current detector is configured to measure armature and field current in each of the DC motors and produce a signal proportional to said currents and a voltage detector is configured to measure voltage applied to each of the DC motors and produce a signal proportional to said voltage. A processor is configured to determine a rotational speed as a function of the measured currents and voltages and configured to apply a correction factor to the determined rotational speed to obtain a corrected rotational speed.Type: GrantFiled: December 20, 2002Date of Patent: November 2, 2004Assignee: General Electric CompanyInventors: Ajith Kuttannair Kumar, Samuel Lyle Hazen
