A valve device in a motor vehicle including a housing; a flow passage arranged in the housing; a flap arranged in the flow passage for closing the flow passage, wherein the flap is secured on an axle, and the axle is rotatably mounted in the housing, and can be driven by an electric motor via a gear unit; and a valve seat arranged in the flow passage, with which valve seat the flap is in contact in a closing position, wherein the axle penetrates the flap at an angle. The part of the axle located in the flow passage has a smaller diameter than in the area of the bearing on the side of the gear unit.

A valve device for a fuel cell arrangement in a motor vehicle includes: a housing; a flow channel that extends in the housing; a spindle mounted rotatably in the housing; a flap fastened to the spindle, the flap being arranged in the flow channel and configured to close off the flow channel, the flap having a bore via which bore the spindle penetrates the flap; a drive configured to drive the flap via the spindle; a valve seat arranged in the flow channel, the valve seat, in a closed position of the flap, being in contact with the flap, wherein the spindle penetrates the flap at an angle and openings of the bore each lead to one side of the flap; and a seal arranged In the bore between the flap and the spindle.

A vehicle having an air intake system includes a charge air cooler, an intake duct, an outlet duct, and a bypass duct. The charge air cooler has a charge air inlet that is disposed at a first end of a charge air cooler core and a charge air outlet that is disposed at a second end of the charge air cooler core. The intake duct extends between an outlet of a turbocharger and the charge air inlet. The outlet duct extends between the charge air outlet and a throttle body having a throttle body valve that is operatively connected to an engine intake manifold. The bypass duct has a bypass valve. The bypass duct is connected to the charge air inlet and the charge air outlet. The bypass valve is configured to selectively facilitate bypass flow through the bypass duct.

The invention is an automobile with two engines, where one engine is mounted in the front of the car and one is mounted in the back of the vehicle. A common drive shaft rotational part is run from engine to engine underneath the vehicle. A machine functioning as both a transmission and a differential is located affixed to the flywheel or clutch of both engines. The common driveshaft is run from trans differential to trans differential. Both engines share a common computer system performing the functions such as ignition and electronic fuel injection.

An intake assembly for an internal-combustion engine includes an intake duct for each cylinder, which communicates with an airbox that includes a filtering element. Each intake duct communicates with the airbox by a respective throttle body. A monitoring channel connects the intake ducts together and is configured for perturbing in a negligible way the dynamics of the fluid inside the intake ducts. Associated to said monitoring duct are sensors for monitoring the pressure inside the monitoring duct and designed to send signals indicating the value of pressure of the fluid taken in by the engine to an electronic control unit.

A surface of a bearing member on a flow passage forming chamber-side is disposed to be exposed to the chamber. The bearing member includes a contact part, with which a side surface of a butterfly valve that is opposed to the bearing member is in contact, on at least a part of the surface of the bearing member on the chamber-side. The bearing member is a radial ball bearing and includes an outer bearing ring that is fitted to an inner periphery of a shaft hole, so that its axial displacement relative to a body is restricted, an inner bearing ring that is fitted on an outer periphery of a rotation shaft radially inward of the outer bearing ring, and a rolling element disposed between the outer bearing ring and the inner bearing ring. The contact part is provided on a surface of the inner bearing ring on the chamber-side.

An intake duct that includes a first flange projecting outward from an edge of the intake duct on a throttle body side. An intake manifold that includes a second flange projecting outward from an edge of the intake manifold on a throttle body side. A plurality of spacers is provided between the first flange and the second flange around the throttle body. The first flange and the second flange are fastened via the plurality of spacers in a state where the throttle body is held between the intake duct and the intake manifold.

An electronic throttle body with an improved structure includes a throttle body. A plurality of vertically through airflow channels are provided on the throttle body, and a butterfly valve controlling a vent flow and a fuel atomizing ring configured to atomize fuel are arranged in each airflow channel. Centers of one or more butterfly valves are connected in series through rotating shafts to implement linked flipping, the rotating shafts are arranged parallel to each other, a drive gear is fixedly mounted to one end of each rotating shaft extending out of the throttle body coaxially, and the rotating shafts rotate synchronously through a servo driving apparatus. The servo driving apparatus and electrically controlled sprays respond synchronously, thereby improving the combustion efficiency of fuel in an engine. When the engine is idle, butterfly valves are directly driven through the servo driving apparatus to accurately control an air inflow of the engine.
