  • Fuel injection apparatus
    Patent number: 4503826
    Abstract: An electronic injector drive module mounted on a fuel injection assembly is cooled by fuel flow through the assembly.
    Type: Grant
    Filed: April 22, 1981
    Date of Patent: March 12, 1985
    Assignee: General Motors Corporation
    Inventors: David R. Kessler, David W. Beiswenger, Andrew J. Makusij
  • Engine induction system
    Patent number: 4475486
    Abstract: A port fuel injection system for an automotive engine has injectors delivering fuel across an air gallery and through subsonic nozzles into the engine inlet manifold to provide enhanced mixing of air and fuel for combustion in the engine. A staged throttle mechanism operates a primary throttle controlling air flow through the air gallery and a secondary throttle controlling air flow directly into the manifold so that the air gallery provides substantially the entire air flow required for low speed light load engine operation.
    Type: Grant
    Filed: February 18, 1982
    Date of Patent: October 9, 1984
    Assignee: General Motors Corporation
    Inventor: David R. Kessler
  • Fuel injection system
    Patent number: 4458650
    Abstract: A throttle body fuel injection system has a pressure regulator which reduces the pressure of the fuel supplied to its electromagnetic injector as the engine induction passage pressure decreases.
    Type: Grant
    Filed: September 23, 1982
    Date of Patent: July 10, 1984
    Assignee: General Motors Corporation
    Inventors: David R. Kessler, Noreen L. Mastro, Jerry R. Scheller, George L. Schultz
  • Throttle body injection apparatus with distribution skirt
    Patent number: 4347823
    Abstract: A hollow, truncated cone-shaped distribution skirt is positioned beneath a fuel injector discharging fuel into a throttle bore of a throttle body injection apparatus whereby to divide induction air flow into two flow paths so as to improve the distribution of the air-fuel mixture following through the throttle bore upstream of the pivotable throttle valve therein.
