| 20120036849 | SIMPLIFIED VARIABLE GEOMETRY TURBOCHARGER WITH VARIABLE FLOW VOLUMES - A variable geometry turbocharger is simplified yet able to maintain pulse energy. In a first embodiment, a turbine housing is provided with a pivoting wall which pivots about a point near the entry to the turbine housing. By moving the wall about the pivot point, the effective volume of the turbine housing volute is varied, thus effectively reducing the volume of exhaust gas in the volute, allowing control of exhaust gas flowing to the turbine wheel.

| 20120036847 | METHOD FOR IMPROVING THE LIGHT-OFF OR REGENERATION BEHAVIOR OF AN AFTERTREATMENT DEVICE IN A VEHICLE SYSTEM - 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. | 02-16-2012 |
