Patent number: 10570835Abstract: A method involves receiving a plurality of engine parameters and a sensed ambient operating condition during operation of an engine and determining a current substitution rate based on the plurality of engine parameter. The method also involves determining at least one of a pre-combustion temperature and an end gas temperature based on the plurality of engine parameters and the sensed ambient operating condition and determining a maximum substitution rate based on at least one of the pre-combustion temperature and the end gas temperature. The method further involves comparing the current substitution rate with the maximum substitution rate and controlling at least one engine parameter among the plurality of engine parameters if the current substitution rate is different from the maximum substitution rate so as to generate the current substitution rate to less than or equal to the maximum substitution rate.Type: GrantFiled: September 4, 2014Date of Patent: February 25, 2020Assignee: Transportation IP Holdings, LLCInventors: Thomas Michael Lavertu, Adam Edgar Klingbeil, Omowoleola Chukwuemeka Akinyemi, Victor Manuel Salazar, Roy James Primus

Patent number: 10119460Abstract: A system includes an engine coupled with a primary shaft that drives a first electric generator for generating electrical power via a gear subsystem. The system also includes a turbocharger assembly having at least one gas turbine engine configured for driving the primary shaft and coupled in parallel with the engine. The turbocharger assembly includes multiple compressors configured to provide a flow of compressed fluid into both the engine and the at least one gas turbine engine and multiple turbines configured to utilize exhausts from both the engine and the one gas turbine for driving the primary shaft. Further, the system includes a controller configured to operate a plurality of valves for controlling optimal intake fluid pressure into the engine and the turbocharger assembly and fuel injections into the engine and the at least one gas turbine engine.Type: GrantFiled: September 18, 2014Date of Patent: November 6, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Roy James Primus, Adam Edgar Klingbeil, Narendra Digamber Joshi, Omowoleola Chukwuemeka Akinyemi, Thomas Michael Lavertu

Patent number: 10094324Abstract: A method of operating an internal combustion engine is provided. The method includes combusting a mixture of fresh air and fuel within multiple cylinders. The method also includes directing a first portion of exhaust gases into a first-stage turbine and a second-stage turbine of a turbocharger for expanding the exhaust gases, directing a second portion of exhaust gases from the exhaust manifold via an exhaust channel bypassing the first-stage turbine and recirculating a third portion of exhaust gases into an intake manifold after mixing with fresh air. The method includes controlling at least one of: reducing a normal engine speed at each engine power setting while maintaining constant engine power level by increasing a fuel injection per cycle; concurrently increasing a flow rate of the third portion of exhaust gas during recirculation; and advancing a fuel injection timing for reducing emission levels that meets Tier 4 requirements.Type: GrantFiled: May 30, 2013Date of Patent: October 9, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Thomas Michael Lavertu, Adam Edgar Klingbeil, Roy James Primus, Omowoleola Chukwuemeka Akinyemi, Venu Gopal Gummadavelli, Barry Allen Record, James Henry Yager

Patent number: 9964056Abstract: A method includes controlling an engine speed based on: intake manifold air temperature and/or intake manifold pressure one, or more, of the following data parameters: an engine load as a function of a fuel level, a fuel injecting timing, an intake oxygen concentration, a constituent concentration from the exhaust gas flow, an engine power, and an engine torque. The method also recirculates a portion of the exhaust gas flow to the combustion cylinders of the engine via a recirculation channel, as a function of intake manifold temperature and/or intake manifold pressure at which the engine is operated. An engine system, other methods, and a non-transitory computer readable medium encoded with a program, to enable a processor-based control unit to control aspects of the engine are also disclosed.Type: GrantFiled: September 18, 2015Date of Patent: May 8, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Roy James Primus, Omowoleola Chukwuemeka Akinyemi, Thomas Michael Lavertu, James Robert Mischler, Venu Gummadavelli Gupta

Patent number: 9903284Abstract: Dual-fuel engine system includes cylinders in which the cylinders have an intake valve and an exhaust valve that control a flow of fluid into and out of a combustion chamber of the corresponding cylinder. The intake valve is configured to have an intake valve closure (IVC) timing. The dual-fuel engine system is configured to operate in a single-fuel mode and a dual-fuel mode. The combustion chamber and a piston are designed to provide a compression ratio. The dual-fuel engine system also includes one or more processors that are operably coupled to and configured to control operation of the first fuel injector. The compression ratio and the IVC timing are selected to achieve a target pre-combustion temperature. The target pre-combustion temperature permits the dual-fuel engine system to operate at a high substitution rate in the dual-fuel mode and at a sufficient fuel efficiency in the single-fuel mode.Type: GrantFiled: October 31, 2016Date of Patent: February 27, 2018Assignee: General Electric CompanyInventors: Thomas Michael Lavertu, Roy James Primus, Venu Gummadavelli Gupta, Sebastian Walter Freund, Omowoleola Chukwuemeka Akinyemi, Adam Edgar Klingbeil, Victor Manuel Salazar
