  • System, method, and apparatus for gas engine enhanced starting
    Patent number: 8751139
    Abstract: A system includes an internal combustion engine having an air intake and a pressurizing device disposed in the air intake. The pressurizing device is a turbocharger or a supercharger. A gaseous fuel supply is fluidly coupled to the air intake at a position upstream of the pressurizing device through a first fluid conduit and fluidly coupled to the air intake at a position downstream of the pressurizing device through a second fluid conduit. A valve is disposed in the second fluid conduit and includes an electronic control input. The valve responds to an electronic signal at the electronic control input. The system includes an engine start indicating device electronically coupled to the electronic control input, where the engine start indicating device provides the electronic signal to open the valve in response to the engine being in a starting operating condition.
