    摘要： A throttle body for an engine or fuel cell of a vehicle is provided. The throttle body comprises a cylindrical housing comprising a first open end extending to a second open end defining an inner wall having an inner surface. The throttle body further comprises a moveable blade valve movably disposed on the inner wall and arranged to regulate air to the engine during operation of the vehicle. The moveable blade valve has an outer surface. The throttle body further comprises a dual-phase thermal composite coating (TCC) disposed on one of the inner surface of the inner wall and outer surface of the moveable blade valve for enhanced thermal conductivity and reduced deposit accumulation on the inner surface and the outer surface. The dual-phase TCC comprises a first material comprising between 10 wt % and 90 wt %, and a second material comprising between 10 wt % and 90 wt % of the dual-phase TCC. The dual phase TCC has a contact angle of between 100° and 160° and a thermal conductivity of at least 0.3 W/mK.

    摘要： An electrically controlled throttle apparatus is constructed with a throttle body and a throttle valve that are simultaneously molded of a resinous material in the same molding dies. The throttle valve is rotatably assembled in a bore wall part of the throttle body while the throttle valve is rotated by a predetermined rotation angle θ between 45° and 135° with respect to a rotation angle 0° corresponding to its full close position. An outer circumferential periphery of the filler, which is molded to be the throttle valve in a cavity of the molding dies, is compressed by a predetermined pressure when the throttle valve and the throttle body are molded. Thus, dispersion of contraction of the throttle valve can be reduced in its molding process by adding the compression process.

    摘要： A valve device for controlling an exhaust gas flow of an internal combustion engine includes a housing comprising a channel which has the exhaust gas flow therethrough. A shaft is disposed in the housing. The shaft is rotatably mounted about a shaft axis. A flap is connected to the shaft. The flap controls a flow cross section of the channel. The flap comprises two flexurally rigid support plates. The support plates each comprise an outer periphery. An elastic flap body is arranged between the support plates. The elastic flap body comprises an outer periphery which is larger on all sides than the outer periphery of the support plates. A distance between the outer periphery of the elastic flap body and the outer periphery of the support plates is largest in an area of the shaft axis, and smallest at an angle of 90° relative to the shaft axis.

    摘要： An engine assembly may include an engine defining a cylinder bore, a fuel tank, a fuel supply assembly in fluid communication with the fuel tank and the cylinder bore, a fuel return assembly in fluid communication with the fuel supply assembly and the fuel tank, and a fuel filter assembly. The fuel filter assembly may include a filter casing having an inlet, an outlet and a bypass opening, and a filter media located within the filter casing. The filter media may be located between the inlet and the outlet, defining a dirty fuel region of the filter assembly between the inlet and the filter media and a clean fuel region between the filter media and the filter outlet. The bypass opening may be in fluid communication with the dirty fuel region and the fuel return assembly to draw gases out of the dirty fuel region.

    摘要： Provided is a throttle valve device for an internal combustion engine which is favorably protected from icing, and enables a favorable control of the intake flow rate by avoiding an abrupt increase in the flow rate particularly in a small opening angle range. An upstream recess (21) and a downstream recess (22) are formed in a lower part of the throttle bore (11) of the throttle valve device. Moisture that may deposit on the inner wall of the throttle bore is allowed to be drained to the recesses. A cross sectional area of one of the recesses over which the lower edge of the throttle valve member sweeps as the throttle valve member (30) opens from the fully closed position is smaller than that of the other recess so that an abrupt change in the intake flow rate can be avoided in a small opening angle region.
