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

System and method for cooling using a heat exchanger having a membrane

Patent Dwyer, Brian P.; Morrow, Charles P.; Pohl, Phillip I.; ...

A heat exchanger that includes a membrane of graphene oxide is disclosed, as is a heat exchange system employing such a heat exchanger. The heat exchanger permits the use of water from non-traditional sources, such as waste water, brackish and sea water, in a cooling loop. Clean water and sensible heat permeate through the membrane, simultaneously cooling and purifying water in the cooling loop.
