Patent number: 10060339Abstract: A system and methods for routing condensate collected in a heat exchanger reservoir to either an air intake system or a position in the engine exhaust based on the type of contaminate in the condensate and operating parameters of the engine or the catalyst are described. In one particular example, condensate is routed to a first position along the engine air intake system in a first mode of operation, and a second position upstream of the catalyst along the engine exhaust in a second mode of operation, and a third position downstream of the catalyst along the engine exhaust in a third mode of operation. When substantially no contaminates are detected, the condensate may be routed into the engine exhaust upstream of the catalyst in order to cool the catalyst.Type: GrantFiled: February 16, 2016Date of Patent: August 28, 2018Assignee: Ford Global Technologies, LLCInventors: Christopher Donald Wicks, Karen Elizabeth Maceroni, Mark Michael Madin

Patent number: 9650973Abstract: Methods and systems are provided for airflow control in an engine system which includes a throttle turbine generator including a turbine and a turbine generator. In one example, a method may include adjusting an angle of a throttle positioned in an engine inlet passage based on a desired airflow by taking into account the effects on the throttle angle due to rotation motion of the turbine, thereby accurately controlling airflow to the engine system. The method may further include predicting an airflow to the engine system based on the position of the throttle, thereby accurately monitoring torque of the engine system.Type: GrantFiled: October 30, 2015Date of Patent: May 16, 2017Assignee: Ford Global Technologies, LLCInventors: John Erik Mikael Hellstrom, Karen Elizabeth Maceroni, Jeffrey Allen Doering, Daniel Joseph Styles

Patent number: 9382836Abstract: A system and methods for routing condensate collected in a heat exchanger reservoir to either a combustion chamber of an engine or a position in the engine exhaust based on the type of contaminate in the condensate and operating parameters of the engine or the catalyst are described. In one particular example, the method includes accumulating a portion of compressed air in an accumulator, and when an engine output is below a predetermined amount, coupling a part of the accumulated air with the condensate through a passage into the combustion chamber. Thereby, the methods described may be used to distribute condensate formed in the heat exchanger even at low engine loads.Type: GrantFiled: December 20, 2013Date of Patent: July 5, 2016Assignee: Ford Global Technologies, LLCInventors: Karen Elizabeth Maceroni, Mark Michael Madin, Christopher Donald Wicks
