Filed:

Sep 4, 2008

Appl. No.:

12/204199

Inventors:

Henry W. Harper - Milford MI, US
Peter Hubl - Clarkston MI, US
Bryan A. Kuieck - Lowell MI, US

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - DETROIT MI

International Classification:

F02M 37/00

US Classification:

123510

Abstract:

A fuel injection priming system includes a fuel supply line connected to a fuel supply rail. A plurality of piezoelectric fuel injectors are connected to the fuel supply rail. An injector return fuel line is connected to the fuel injectors and in communication with a fuel supply line via a diverter valve to allow pressure fuel from the high pressure fuel pump return line to pressurize the injector return fuel line to backfill the injectors during a priming operation. A fuel restriction device is in communication with the diverter valve to restrict fuel flow through the injector return line to provide sufficient backfill for the fuel injectors during the priming operation and to allow fuel to pass to the fuel tank from the injector return fuel line during normal operation.

F01N 3/021
F02B 37/04

US Classification:

60600, 606052, 60602

Abstract:

In one exemplary embodiment of the invention, an internal combustion engine includes a turbocharger configured to receive an air flow and a first exhaust flow from the internal combustion engine and a supercharger downstream of the turbocharger configured to receive a compressed air charge from the turbocharger. The engine further includes an exhaust gas recirculation circuit receiving a second exhaust flow from the internal combustion engine and supplying the second exhaust flow to the compressed air charge upstream of the supercharger, wherein the second exhaust flow and compressed air charge comprise an exhaust-air mixed flow received by the internal combustion engine.

International Classification:

F02D 23/00

US Classification:

60602

Abstract:

A method of controlling airflow of an engine system is provided. The method includes determining a supercharger operating mode and a turbocharger operating mode based on engine load; selectively generating a control signal to a turbocharger based on the turbocharger operating mode; and selectively generating a control signal to a supercharger bypass valve based on the supercharger operating mode.
