Present embodiments provide an electronic fuel injection throttle body which may be used with a variety of engines of different manufacturers. The throttle body may be used to replace mechanical or hydraulically controlled carburetors with electronic fuel injection. The bores or barrels of the throttle body may comprise one or more stackable fuel injectors. The fuel component cover may include a regulator with a housing for integrally with the fuel component cover or alternatively, a regulator may be located remotely.

Provided is a throttle valve assembly which reduces weight, number of manufacturing processes, and manufacturing cost thereof by coupling a throttle body formed of plastic to a reinforcement portion manufactured by a die casting method with an insert method. The throttle valve assembly includes a valve body having an intake passage, a mounting space that communicates with the intake passage, a motor accommodating space, and a mounting groove formed between the mounting space and the motor accommodating space. The valve body includes plastic. The throttle valve assembly further includes a valve plate coupled to a rotary shaft rotatably installed in the intake passage of the valve body to adjust an amount of air or a mixed gas ingested into an engine; and a reinforcement portion formed of a metal and coupled to an inside of the valve body by an insert injection method.

An engine includes: a throttle body that is joined to an intake port and that makes a butterfly valve within an intake path actuate based on driving force of an electric actuator so as to adjust an opening degree of the intake path; a receptor that extends from the throttle body to a direction distant from the throttle body above a crankcase and that receives the electric actuator therein; and a supporting piece that extends from the receptor to the direction distant from the throttle body and that is supported on the crankcase. Accordingly, in the engine, it is possible to alleviate the influence of vehicle vibrations on the throttle body and actuator by enhancing the rigidity with which to support the throttle body and actuator in a simple structure.

A throttle valve housing (1) for a throttle valve arrangement for an internal combustion engine, wherein the throttle valve housing (1) is used to accommodate a pivotally mounted throttle valve and provides movement space for the throttle valve, wherein the throttle valve housing (1) has an inflow opening (2) on a first side for receiving a fluid and the throttle valve housing (1) has an outflow opening (3) on a second side for discharging a fluid, and wherein at least one sealing piece (4) projecting into the flow cross-section is arranged in the movement space of the throttle valve housing (1) and is used as a stop for the throttle valve in the closed position. Improved sealing characteristics are achieved in that the sealing piece (4) is formed in the wall of the throttle valve housing (1) in a non-cutting manner.

A coupling device couples a drive shaft of a pivot drive (30) of an exhaust gas stream exhaust flap (10) for an internal combustion engine with a pivot shaft (14), which is rotatable about a pivot axis (A) and carries a flap diaphragm (16). The coupling device includes a coupling element (46) with a first coupling area (42) positive-locking meshing with a drive shaft (34) and with a second coupling area (44) positive-locking meshing with a pivot shaft. A prestressing element (58) is supported in relation to the coupling element and in relation to a support element (66) and prestresses the coupling element in a direction of a coupling axis (K), axially away from the support element and in a circumferential direction. A preassembly-blocking device (78) holds the support element under axial prestress and circumferential prestress in a preassembled position in relation to the coupling element.

A throttle control assembly which includes a housing, and an adapter and an anti-rotation feature integrally formed with the housing. A scallop is integrally formed as part of the housing and substantially surrounds the anti-rotation feature. A first tapered portion and a second tapered portion are both integrally formed with the adapter. A first groove and a rib portion are also integrally formed as part of the adapter. A plurality of outer scallops are also integrally formed as part of the adapter. The anti-rotation feature, the scallop, and each of the plurality of outer scallops are integrally formed with the housing. A portion of the plurality of outer scallops are formed as part of the second tapered portion, and a portion of the plurality of outer scallops are formed as part of the rib portion.

An exhaust gas flap, especially for the exhaust gas stream of an internal combustion engine, includes a flap tube (24), a flap diaphragm (26). The flap diaphragm (26) is carried in the interior of the flap tube (24) on a pivot shaft (18), rotatable about a pivot axis (A). The flap diaphragm (26) has at least one flap diaphragm part (28, 30) and a mounting area (40) enclosing the pivot shaft (18) in at least some areas. A wing stop (42, 44) is provided at an inner circumferential area of the flap tube (24) in association with at least one flap diaphragm part (28, 30). A recess (60, 62, 64, 66) at the flap diaphragm (26), receiving a circumferential end area (48, 50) of a wing stop (42, 44), is provided in at least one axial end area of the mounting area (40).

An exhaust gas flap includes a flap tube (12), a flap diaphragm (16), in an interior of the flap tube on a pivot shaft (14) rotatable about a pivot axis (A), a pivot drive (30) for the pivot shaft (14) and a coupling device (36) coupling the pivot shaft to a drive shaft (34). The coupling device includes a first coupling area (42) rotationally coupled, positive-lockingly meshed with the drive shaft and a second coupling area (44) rotationally coupled, positive-lockingly meshed with the pivot shaft. A biasing element (58) is supported in relation to the coupling device and in relation to one shaft of the drive shaft and the pivot shaft. The coupling device is axially prestressed, by the prestressing element, away from the one shaft along in the direction of the pivot axis and is prestressed about the pivot axis in relation to the one shaft.

A regulating device for an internal combustion engine includes an exhaust gas recirculation pipe which opens into an intake pipe which are both formed in a housing, and a regulating element eccentrically mounted on a shaft. The shaft is arranged perpendicular to a center line of the intake pipe and the exhaust gas recirculation pipe. The regulating element includes a first surface, a second surface, and guide ribs arranged on the first surface. In a first end position of the regulating element, in which the intake pipe is at least throttled upstream of an opening of the exhaust gas recirculation pipe, a normal vector of the first surface points to an upstream side of the intake pipe. In a second end position of the regulating element, in which the exhaust gas recirculation pipe is closed, a normal vector of the second surface points to the exhaust gas recirculation pipe.

An engine having a linkage assembly, the linkage assembly having a governor lever, a governor shaft, and a throttle link. The governor lever couples the governor shaft to the throttle link. The governor lever is configured to adjust the relative position between the throttle link and the governor shaft. The governor lever has a primary arm and a secondary arm, the primary arm being movable with respect to the secondary arm. The primary arm and secondary arm are secured via a fastener which prevents relative motion between the primary and secondary arms.
