  • Diesel fuel engine injection system and method therefor
    Patent number: 9249745
    Abstract: Disclosed is a method of injecting natural gas into a diesel fuel engine for combustion with diesel fuel therein. One aspect includes injecting natural gas into an air-stream of an engine air intake or manifold, measuring the percentage of natural gas injected into the airstream or other efficiency gauge, varying the rate of injection of natural gas into the airstream in response to the measured percentage of natural gas therein and injecting the natural gas at a pre-determined rate so as to maintain an natural gas concentration in the air intake stream in the range of 0.6% to 3.0% by volume of natural gas.
    Type: Grant
    Filed: March 11, 2015
    Date of Patent: February 2, 2016
    Assignee: Gas Tek Solutions Pty. Ltd.
    Inventors: Derek Robert Watkins, Bruce Robert Watkins, Keith Murray Rumbel

  • Diesel fuel engine injection system and method therefor
    Patent number: 8991362
    Abstract: Disclosed is a method of injecting LPG gas into a diesel fuel engine for combustion with diesel fuel therein. One aspect includes injecting LPG gas into an air-stream of an engine air intake or manifold, measuring the percentage of LPG gas injected into the airstream or other efficiency gauge, varying the rate of injection of LPG gas into the airstream in response to the measured percentage of LPG gas therein and injecting the LPG gas at a pre-determined rate so as to maintain an LPG gas concentration in the air intake stream in the range of 0.2% to 0.6% by volume of LPG gas.
