Abstract: A mixer assembly (204, 603) for mixing intake air from an intake system (124) with exhaust gas from an exhaust gas recirculation system (134) to yield a mixture stream includes an intake air conduit (202, 700) having an inlet (206, 706) fluidly connected to the intake system. The mixer assembly (204, 603) also includes a mixer (200, 600) having an inlet (208, 702) fluidly connected to the exhaust gas recirculation system (134). The mixer (200, 600) is at least partially disposed in the intake air conduit (202, 700) and includes an outer pipe (203, 604) and a dividing portion (217, 602) disposed within the outer pipe. The dividing portion (217, 602) divides a first passage (216, 612) from at least one second passage (218, 608), the first passage having an outlet (216?, 612?) that is at a first height, and the second passage having an outlet (218?, 608?) that is at a second height.

Abstract: An in-line opposed cylinder engine constructed of a pair of half blocks which when combined form a pair of spaced cylinder heads and an intermediate crankcase and in which the cylinder heads and the intermediate crankcase are tied together by a plurality of spaced elongated through bolts which extend through the cylinder heads and through the half blocks. Each cylinder head is integral with the remainder of the half block and is preferably of a composite construction with a core of steel or the like which forms the cylinder bore, the firing deck, the exhaust ports and the valve guide as well as the main bearing supports. A matrix structure of lighter material such as aluminum is cast around the core and forms the induction air passages to the intake ports, the coolant passages, oil passages, and the main bearing bosses.

Abstract: A turbine engine construction comprises an accessory drive mechanism in which accessories are mounted circumferentially around the turbine casing. The engine includes a planetary gear mechanism driven by a shaft extending axially outward from compressor and turbine sections of the engine, and forwardly of the air intake in the turbine casing. Accessory drive assembly includes a planetary gear mechanism having a ring gear exposed through circumferentially spaced apertures in the turbine casing to driven gears extending outwardly from accessory housings secured to the periphery of the turbine casing.

Abstract: A torque measuring device is provided for measuring the engine torque of an engine having an output shaft and connecting through a gear box having a planetary gear arrangement to a load. The torque measuring device comprises a hub having an axis and supporting the stationary member of the planetary gear arrangement coaxial with the axis of the hub. An annulus is secured to and supports the gear box housing and is also secured to the hub by a plurality of circumferentially spaced spokes extending between the annulus and the hub and tangent to some circle coaxial to the hub. As the torque applied to the planetary gear arrangement increases, the hub rotates from its at rest position deflecting the spokes in proportion to the reaction torque of the stationary members. An arm extending outwardly from the hub cooperates with a position transducer to measure the amount of rotation of the hub with respect to the annulus and thus the torque on the planetary gear arrangement.
