Engine system and method including first and second turbochargers

Lusardi, Christopher

Title: Engine system and method including first and second turbochargers

Abstract

An engine system includes an internal combustion engine having an intake passage, a first set of combustion chambers, a second set of combustion chambers, a first exhaust passage fluidly connected to the first set of combustion chambers, and a second exhaust passage fluidly connected to the second set of combustion chambers. The engine system includes a first turbocharger including a first compressor and a first turbine. The engine system also includes a second turbocharger including a second compressor and a second turbine, the second compressor connected in series with the first compressor, and the second turbine being in fluid communication with the second exhaust passage. The first and second turbines are connected in parallel such that the first turbine only receives exhaust flow from the first set of combustion chambers, and the second turbine only receives exhaust flow from the second set of combustion chambers.

Sighting optics including an optical element having a first focal length and a second focal length and methods for sighting

Patent Crandall, David Lynn

Sighting optics include a front sight and a rear sight positioned in a spaced-apart relation. The rear sight includes an optical element having a first focal length and a second focal length. The first focal length is selected so that it is about equal to a distance separating the optical element and the front sight and the second focal length is selected so that it is about equal to a target distance. The optical element thus brings into simultaneous focus for a user images of the front sight and the target.

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
