Patent number: 9739213Abstract: A system and methods are described for a turbocharged engine, comprising powering the engine using a first operating cylinder, supplementing the power using a second switchable cylinder, deactivating the second switchable cylinder responsive to a load below a first threshold, and closing a first shut-off valve downstream of a compressor during the partial deactivation to prevent a first turbocharger from imparting a delivery action into a second compressor during the partial deactivation. Embodiments are further described wherein a bypass line in a second exhaust line further serves as a short-circuit line to prevent the second compressor from imparting a delivery action against the closed first shut-off valve. A variable valve timing is then included to further optimize the combustion process during the partial deactivation.Type: GrantFiled: March 26, 2015Date of Patent: August 22, 2017Assignee: Ford Global Technologies, LLCInventors: Joerg Kemmerling, Franz Arnd Sommerhoff, Andreas Kuske, Vanco Smiljanovski, Helmut Matthias Kindl, Werner Willems, Claudia Katharina Herudek, Michael Forsting, Bas Lambertus van den Heuvel, Wilbert Hemink, Claudia Conee, Richard Fritsche

Patent number: 9644575Abstract: The system and methods described allow for reduce emissions by using a recirculation device within an engine that connects an air feed line to an exhaust line while cooling the exhaust-gas to form a condensate for further cooling the engine system. In one particular example, a cooling unit is described that cools the exhaust-gas stream flowing there through and collects a condensate out of the exhaust-gas stream for injection back into the air feed line via an injecting device. In this way, an injection of water may be made to reduce NOx emissions during vehicle operations, and the outlay for storage of water on board the vehicle may be eliminated.Type: GrantFiled: January 6, 2014Date of Patent: May 9, 2017Assignee: Ford Global Technologies, LLCInventors: Helmut Hans Ruhland, Werner Willems, Claudia Katharina Herudek, Claudia Conee, Guohui Chen
