Patent number: 9915197Abstract: A method of setting actuator position of a variable geometry turbine linked to drive a compressor for a compression ignition engine using exhaust gas recirculation. The method includes detecting an engine transient event; determining current mass air flow through the compressor and exhaust temperature; resetting variable geometry turbine position to maximize mass air flow through the compressor; adding the maximum allowable quantity of fuel; determining exhaust temperature increase; adjusting exhaust pressure to allow an increase in mass air flow and exhaust temperature; and returning to the resetting step until a limit is reached.Type: GrantFiled: June 26, 2012Date of Patent: March 13, 2018Assignee: International Engine Intellectual Property Company, LLC.Inventors: Luis C. Cattani, Michael Uchanski, Rogelio Rodriguez, James R. Cigler, Jeremy G. Schipper, Jer Sheng Chen, Dileep Khadilkar, Shree C. Kanchanavally, John R. Zagone, Daniel Cornelius

Patent number: 9121363Abstract: A method is provided for operating an engine to limit soot emissions during fuel-enriched operation. The method includes operating the engine using a first fuel injection pattern and timing to inject fuel into a combustion chamber of the engine. The method further includes receiving a request for an increased engine power output and operating the engine using a second fuel injection pattern and timing to inject more fuel into the combustion in response to the request for the increased power output, where the second fuel injection pattern and timing is configured to minimize soot emissions during enriched fuel operations, such as during transient operations.Type: GrantFiled: September 27, 2012Date of Patent: September 1, 2015Assignee: International Engine Intellectual Property Company, LLCInventors: Luis Carlos Cattani, Michael Uchanski, Rogelio Rodiguez, Jer Shen Jason Chen, Dileep Khadilkar, Rahul Dev Rajampeta, Jeremy Grant Schipper, Eric Kastanis

Publication number: 20140083392Abstract: The present technology provides one or more methods of operating an engine in a motor vehicle. In at least one embodiment, the existence of an engine idle condition is determined. The method may also include determining whether an operator is present in the vehicle. In some embodiments, the engine operates at a performance idle speed when an engine idle condition exists and an operator is present in the vehicle. In further embodiments, the engine operates at a fuel economy idle speed when an idle condition exists and no operator is present in the vehicle. In still further embodiments, the fuel economy idle speed will be lower than the performance idle speed. The present technology anticipates engine workload and controls engine idle speeds. Based on the anticipated workloads, the present technology can reduce engine stalling while also reducing emissions and increasing fuel economy.Type: ApplicationFiled: September 27, 2012Publication date: March 27, 2014Applicant: International Engine Intellectual Property Company, LLCInventors: Luis Carlos Cattani, Michael Uchanski, Rogelio Rodiguez, James Ciglar, Jer Shen Jason Chen, Dileep Khadilkar, Rahul Dev Rajampeta, Ravi Rayala

Publication number: 20140086803Abstract: A system for improving NOx reduction by incorporating an upstream treatment housing having a dual functionality catalyst that includes a diesel oxidation catalyst and a three-way catalyst, and which is positioned upstream of a main exhaust gas treatment system. The upstream treatment housing is positioned in relative close proximity to an exhaust turbine to prevent or minimize a reduction in exhaust gas temperature as the exhaust gas travels between the outlet of the turbine and the upstream treatment housing. By preventing such a reduction in exhaust gas temperature, the three way catalyst in the upstream treatment housing may operate at exhaust gas temperatures higher than those in main exhaust gas treatment system, which may allow for NOx conversion in the upstream treatment housing during certain cold operating or ambient conditions that is not typically attained in the main treatment system during such conditions.Type: ApplicationFiled: September 27, 2012Publication date: March 27, 2014Applicant: International Engine Intellectual Property Company, LLCInventors: Carlos Luis Cattani, Michael Uchanski, Rogelio Rodiguez, Dileep Khadilkar, Nishant Singh, Joao P.
