Abstract: A method of operating the turbine booster to improve engine operating response and to increase the effectiveness of emission control devices is disclosed. A turbocharger turbine booster for a turbo charged internal combustion engine provides pressurized air to the turbocharger turbine and increases the oxygen in engine exhaust without increasing the engine combustion oxygen content.

Abstract: A system and method for controlling passive soot oxidation in a diesel particulate filter that includes sensing the temperature of exhaust gases upstream and downstream of the diesel particulate filter. The sensed temperatures are used by a control unit to predict whether the temperature of the exhaust gas within the diesel particulate is within a predetermined temperature range for passive oxidation of soot in the diesel particulate filter. If the temperatures are below passive oxidation temperatures, an auxiliary component is activated that increases the temperature of exhaust gas delivered to the diesel particulate filter. When the exhaust gas temperature within the DPF is predicted to be within passive oxidation levels but below active regeneration temperatures, the auxiliary component is deactivated.

Abstract: The present technology provides systems for monitoring particulate matter buildup on a filter installed in the engine exhaust stream of a vehicle. A filter differential pressure sensor monitors a pressure differential across the filter. A downstream differential pressure sensor monitors a pressure differential across an exhaust stream outlet. A processor monitors a particulate buildup value based at least in part on the pressure differential across the filter and the pressure differential across the exhaust stream outlet. A method for monitoring particulate buildup is also provided. The method monitors a pressure differential across the filter, and determines a downstream exhaust flow rate based on a pressure differential between a filter outlet housing and an exit pipe, where the diameter of the filter outlet housing is greater than the diameter of the exhaust exit pipe.

Abstract: A vehicle panel with a folded-over or wrapped edge is disclosed. The vehicle panel comprises a main body portion. The main body portion includes a first layer and a second layer. The first layer is formed of a substantially rigid material and has a first surface, a second surface and an edge. The second layer is coupled to the second surface of the first layer and formed of a substantially flexible material. The vehicle panel also comprises a flap integrally formed with the main body portion at the edge and comprises at least the second layer. The vehicle panel further comprises a hinge separating the flap from the main body portion, the hinge is defined by at least a portion of the first layer having a reduced thickness. The flap is folded back about the hinge towards the first surface of the first layer to substantially conceal the edge.

Abstract: A system and method of effective regeneration of a diesel particulate filter used in the exhaust system of a diesel engine during low engine operating temperatures, is disclosed. Generally speaking, a catalytic burner system and method used in filter regeneration on a diesel engine comprises a burner diesel oxidation catalyst (BDOC) coupled to an exhaust flow of the diesel engine, a mixer fluidly coupled to the BDOC, a diesel oxidation catalyst (DOC) fluidly coupled to the mixer, and a diesel particulate filter (DPF) fluidly coupled to the DOC, wherein the BDOC directs the exhaust flow through the mixer, the DOC and the DPF during a regeneration cycle of the DPF under low engine temperature operating conditions.

Abstract: A system and method for efficient regeneration of a diesel particulate filter used in the exhaust system of a diesel engine, is disclosed. In various systems, a burner is incorporated into the exhaust stream, and prior to the diesel particulate filter. Because the burner requires precise amounts of fuel and air to operate properly, an air flow delivery device, such as a positive displacement pump or blower is incorporated into the system to channel boost air to the burner. Alternatively, a bypass line may be used in conjunction with a pressure regulator, wherein the bypass line diverts the boost air from the pump or blower, while the pressure regulator controls the final pressure to the burner.
