  • Gaseous fuel-air mixer with higher mixture uniformity
    Patent number: 11933250
    Abstract: A gaseous fuel-air mixer includes an outer shell, an inner shell, and a fuel chamber rib. The outer shell includes an air intake and a fuel intake. The air intake is configured to receive air. The air intake has an air outlet. The fuel intake has a fuel inlet that is configured to receive fuel. The inner shell includes an inner shell intake that is configured to separately receive the air from the air outlet and the fuel from the fuel intake and to provide a gaseous fuel-air mixture. The inner shell cooperates with the outer shell to define a fuel intake collecting chamber that is configured to receive the fuel from the fuel inlet and a fuel intake concentrating chamber that is configured to receive the fuel from the fuel intake collecting chamber and provide the fuel to the inner shell intake.

  • Turbocharger compressor bypass coaxial re-introduction system to optimize transient load response
    Patent number: 11174822
    Abstract: A compressor bypass reintroduction system includes a compressor intake manifold and a bypass conduit. The compressor intake manifold defines a fluid plenum. The compressor intake manifold is engageable with a compressor. The bypass conduit extends into the fluid plenum and includes an ejector line. The ejector line is configured to be substantially collinear with the compressor and to discharge flow toward the compressor. In some embodiments, an outlet of the ejector is disposed proximate to an outlet of the fluid plenum that discharges flow into the compressor.
