Patent number: 8601813Abstract: One embodiment may include a method of controlling exhaust gas recirculation (EGR) in a turbocharged compression-ignition engine system including a high pressure (HP) EGR path and a low pressure (LP) EGR path. The method may include determining a target total EGR fraction for compliance with exhaust emissions criteria, and determining a target HP/LP EGR ratio to optimize other engine system criteria within the constraints of the determined target total EGR fraction. The determining of the target HP/LP EGR ratio may include using at least engine speed and load as input to a base model to output a base EGR value, using at least one other engine system parameter as input to at least one adjustment model to output at least one EGR adjustment value, and adjusting the base EGR value with the at least one EGR adjustment value to generate at least one adjusted EGR value.Type: GrantFiled: March 14, 2008Date of Patent: December 10, 2013Assignee: BorgWarner Inc.Inventors: John Shutty, Volker Joergl

Patent number: 8490387Abstract: The process of active DPF regeneration requires that the DPF be brought to regeneration temperatures in excess of 550° C. to 600° C. for a period of time sufficient to accomplish soot burnoff in the DPF. Similarly, during cold start up it is desirable to bring the catalyst to light off temperature as soon as possible. The large thermal inertia of one or more turbochargers delays the exhaust gas at the DPF from reaching critical temperature quickly. The incorporation of a low thermal inertia, insulated, turbocharger bypass duct avoids thermal energy loss from exhaust gas to the turbine housing and shortens the time for the DPF to reach critical temperature for active DPF regeneration, or in the case of a catalytic converter, shortens time for catalyst to reach light off temperature.Type: GrantFiled: April 19, 2010Date of Patent: July 23, 2013Assignee: BorgWarner Inc.Inventors: Gert Schreiber, Volker Joergl

Patent number: 7757679Abstract: An engine assembly (10) comprising an engine, a plurality of coolers, a plurality of bypasses, and at least one actuator (32). The engine has an exhaust manifold and an intake manifold. The gaseous fluid exiting the exhaust manifold is recirculated to the intake manifold. The exhaust gas passes through either an air cooler or a bypass. At least one actuator is operably connected to the plurality of bypasses. The bypasses have a valve (28, 30) which is actuated to control the flow of the gaseous fluid through the bypass as both the bypass and the cooler. Therefore, when a single actuator is used to control the valves in both bypasses, the valves in the bypasses have the same relationship with the inlets so that a single actuator movement will control both valves in the same manner.Type: GrantFiled: March 22, 2007Date of Patent: July 20, 2010Assignee: BorgWarner, Inc.Inventors: Volker Joergl, Timm Kiener, Olaf Weber, Robert S.
