    摘要： An engine device for an unmanned flying apparatus that provides good weight balance for the flying apparatus; cancels the gyroscopic effect; and has auto rotating propellers.
    The engine device includes a first cylinder and a second cylinder arranged horizontally and opposed to each other, and pistons within the cylinders advance and retract in opposite directions to each other; a first crankshaft and a second crankshaft arranged in the vertical direction, driven by the first cylinder and the second cylinder, respectively, and rotate in opposite directions; a first centrifugal clutch and a second centrifugal clutch rotate in opposite directions to each other; a final drive shaft transmitting rotational force to a gear mechanism comprising orthogonal transform gears, to rotate a propeller shaft; a one-way clutch arranged between



    the first crankshaft, the second crankshaft and
    the final drive shaft, and driven by both the first crankshaft and the second crankshaft.

    摘要： A muffler for an exhaust system of an internal combustion engine having a muffler body, a first chamber defined in the muffler body, a second chamber disposed at least in part in the first chamber, and a third chamber disposed at least in part in the first chamber. The second chamber has an inlet, an outlet, and at least one side wall. The at least one side wall of the second chamber defines at least one aperture fluidly communicating with the first chamber. The third chamber has an inlet, an outlet, and at least one side wall. The at least one side wall of the third chamber defines at least one aperture fluidly communicating with the first chamber. The outlet of one of the second and third chambers fluidly communicates with the first chamber. A vehicle having the muffler is also disclosed.

    摘要： A diffuser nozzle for a gas turbine engine includes a housing disposed about a nozzle axis and extending between a first nozzle end and a second nozzle end. The housing defines a nozzle duct. A plurality of walls is disposed within the nozzle duct. The plurality of walls subdivides the nozzle duct into a plurality of duct sections. The plurality of walls further defines a plurality of axially-extending duct segments of the nozzle duct such that within a first axially-extending duct segment, the duct cross-sectional area of a first duct section of the plurality of duct sections is greater than the duct cross-sectional area of each other duct section and within a second axially-extending duct segment, the duct cross-sectional area of a second duct section of the plurality of duct sections is greater than the duct cross-sectional area of each other duct section.

    摘要： Provided is an exhaust gas combustion device which is capable of early prevention of clogging, and also a power generator including the device. An exhaust gas combustion device of the present invention includes: a DPF; a sensor which measures the pressure of exhaust gas to be introduced into the DPF; a sensor which measures the pressure of exhaust gas purified by the DPF; and a controller which receives outputs from both sensors and calculates a pressure difference. When the pressure difference is equal to or larger than a preset threshold, the heater is supplied with power from a power generating unit to thereby heat exhaust gas. Accordingly, PM accumulated inside the DPF is combusted and removed, preventing excessive clogging of the DPF even during light-load operation.
