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.

A fuel conditioning and measuring system for testing diesel engines includes a fuel conditioning loop having first and second heat exchangers, one employing a heating medium, and one employing a cooling medium. Flow of the heating and cooling mediums to the heat exchangers is controlled by control valves which receive a signal indicative of the temperature of the fuel flowing through the system and compare the measured temperature to a desired temperature to generate a control signal for positioning the control valves appropriately. A mixing tank serves as a buffer between the fuel supply and the test engine to ensure any disturbances from fuel returning from the test engine do not adversely affect the testing of the engine, and provides a mechanism by which the temperature of the fuel can be more accurately controlled. A flow meter and a density meter measure the flow of fuel through the system to provide accurate indications of mass and volumetric flow.
