One embodiment of the invention 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.
摘要:
A method including selectively injecting non-cooled exhaust gas into a primary air intake conduit at a first location; selectively injecting cooled exhaust gas into the primary air intake conduit at a second location; and wherein the second location is downstream from the first location with respect to the direction of gas flow in the primary air intake conduit.
摘要:
A valve assembly for use in an air management assembly having an engine, an exhaust side, and an intake side, where the valve assembly provides a housing, a plurality of openings in the housing, a valve in the housing, and an actuator operably connected to the valve. The housing is in fluid communication with the exhaust side and the intake side. The plurality of openings in the housing form at least one inlet and at least one outlet in the housing. The valve moves with respect to the plurality of openings.
摘要:
A method of controlling exhaust gas recirculation (EGR) in a turbocharged compression-ignition engine system including an engine, an induction subsystem in upstream communication with the engine, an exhaust subsystem in downstream communication with the engine, a high pressure EGR path between the exhaust and induction subsystems upstream of a turbocharger turbine and downstream of a turbocharger compressor, and a low pressure EGR path between the exhaust and induction subsystems downstream of the turbocharger turbine and upstream of the turbocharger compressor. A target total EGR fraction for compliance with exhaust emissions criteria is determined, then a target HP/LP EGR ratio is determined to optimize other engine system criteria within the constraints of the determined target total EGR fraction.
