Abstract: Systems and methods for simulating electro-hydraulic (EH) braking of a work machine using a combination of hydraulic braking and engine braking may include determining a commanded brake pressure requested by an operator, determining an available engine braking force, and comparing the available engine braking force to a maximum available bleed pressure that is available to reduce a hydraulic braking force. An engine braking output and a pressure reducing valve output pressure may be determined based on the available engine braking force and the maximum available bleed pressure. A pressure reducing valve may be actuated so that the hydraulic braking force is equal to the commanded brake pressure minus the pressure reducing valve output pressure, and a transmission may be actuated so that the engine applies an engine braking force equivalent to the engine braking output to brake the work machine.

Abstract: A method and apparatus for mixing a first stream of gas with a second stream of gas is provided. The method includes introducing a first stream of gas into a first stream manifold and directing the first stream from the first stream manifold into a mixing chamber via a plurality of first stream passages flow coupled to the mixing chamber. A second stream of gas is directed into the mixing chamber via at least one second stream passage flow coupled to a first end of the mixing chamber. A combined stream is formed from the first and second streams, gradually converged, and discharged from the mixing chamber through a mixing chamber exit port.

Abstract: The present invention includes an apparatus adapted to heat actuating fluid in a rail passage located within an engine. The rail passage is connected to an fluid inlet of at least one fuel injector. The apparatus includes a heating device located within the rail passage. The heating device is adapted to heat the actuating fluid, in response to a control signal. The apparatus also includes a temperature sensing device located within the rail passage. The temperature sensing device is adapted to sense a temperature of the actuating fluid and responsively generate a temperature signal. In the preferred embodiment, the apparatus also includes an electronic controller adapted to receive the temperature signal, determine a temperature of the fluid, and responsively generate the control signal and deliver an injection command signal to the fuel injector.
