Abstract

A system includes an exhaust gas an exhaust gas recirculation (EGR) mixer which includes a housing and a first passage in the housing. The first passage may be configured to supply an EGR flow into the housing. The system further includes a second passage in the housing, such that the second passage is disposed about the first passage. The second passage is configured to supply at least one fluid flow into the housing. The system also includes a region downstream from the first and second passages, and a fluid outlet downstream from the region.

Dedicated exhaust gas recirculation control systems and methods

Patent Sczomak, David P.; Narayanaswamy, Kushal; Keating, Edward J.

An engine control system of a vehicle includes a fuel control module that controls fuel injection of a first cylinder of an engine based on a first target air/fuel ratio that is fuel lean relative to a stoichiometric air/fuel ratio and that controls fuel injection of a second cylinder of the engine based on a second target air/fuel ratio that is fuel rich relative to stoichiometry. The first cylinder outputs exhaust to a first three way catalyst (TWC), and the second cylinder outputs exhaust to an exhaust gas recirculation (EGR) valve. An EGR control module controls opening of the EGRmore » « less

Control method for turbocharged diesel engines having exhaust gas recirculation

Patent Kolmanovsky, Ilya V [Ypsilanti, MI]; Jankovic, Mrdjan J [Birmingham, MI]; Jankovic, Miroslava [Birmingham, MI]

A method of controlling the airflow into a compression ignition engine having an EGR and a VGT. The control strategy includes the steps of generating desired EGR and VGT turbine mass flow rates as a function of the desired and measured compressor mass airflow values and exhaust manifold pressure values. The desired compressor mass airflow and exhaust manifold pressure values are generated as a function of the operator-requested fueling rate and engine speed. The EGR and VGT turbine mass flow rates are then inverted to corresponding EGR and VGT actuator positions to achieve the desired compressor mass airflow rate andmore » « less

Integrated exhaust gas recirculation and charge cooling system

Patent Wu, Ko-Jen

An intake system for an internal combustion engine comprises an exhaust driven turbocharger configured to deliver compressed intake charge, comprising exhaust gas from the exhaust system and ambient air, through an intake charge conduit and to cylinders of the internal combustion engine. An intake charge cooler is in fluid communication with the intake charge conduit. A cooling system, independent of the cooling system for the internal combustion engine, is in fluid communication with the intake charge cooler through a cooling system conduit. A coolant pump delivers a low temperature cooling medium from the cooling system to and through the intakemore » « less
