Definitions

  • the present invention relates to a combustion air guiding device for an internal combustion engine, having an air duct and a throttle valve pivotally arranged within the air duct, the outer contour of which is designed to be complementary to the inner contour of the air duct.
  • a generic combustion air guiding device of the internal combustion engine is supplied to the required air for combustion.
  • the passage cross-section of the air duct which may for example have a circular inner contour, be increased or decreased.
  • the cross-sectional area of the air duct that is released by the throttle for the air passage changes.
  • the internal combustion engine is ne then assigned the required amount of fuel, which is then injected via injectors, for example, cylinder selectively.
  • An influencing criterion for the power development of the internal combustion engine is the starting opening angle or flap basic angle of the throttle valve in the air duct. This is the angle that the throttle assumes relative to the aforementioned vertical axis in the unactuated position of the throttle.
  • the throttle valve is exposed in the air duct due to the prevailing fluid dynamics in both directions of the air duct acting dynamic gas forces that are taken into account in the design of the throttle and that cause the throttle must have a certain minimum thickness, so that it has sufficient strength values for the gas forces acting on it.
  • the pivotable mounting of the throttle flap in the air duct is usually implemented via a shaft which is mounted in the air duct.
  • the aforementioned valve base angle of, for example, 8.5 degrees is now required to avoid a geometrical collision of the outer peripheral portion of the throttle body of the throttle valve with the inner peripheral wall of the air guide passage. If it comes to such a geometric collision, this leads to a sticking of the throttle body in the air duct, which must be avoided in any case, as this means that the throttle body can no longer or only with great forces solved and thus can be opened , In addition, the sticking would lead to attrition on the throttle body and the inner peripheral wall of the air duct.
  • This 8.5 degree angle results from a caliper thickness of 1.2 mm determined for strength reasons and a diameter of the 10 mm shaft provided for actuating the throttle.
  • a smaller valve base angle results in the given configuration to an unwanted physical contact between the throttle valve and the air duct.
  • a flap with a smaller thickness is disadvantageous because it is prone to damage in the event of Backfiring the engine and then replaced.
  • the driver passes over a bump in the shape of, for example, bumps, a roadway, a manhole cover, railroad tracks, or the like, this results in a corresponding reaction of the chassis of the motorcycle and a momentary impulse response of the driver's center of gravity in the direction of vehicle axis.
  • the driver adheres to the steering device, such as the handlebar of the motorcycle, so that transmits the impulse response to the throttle grip.
  • the driver should hold the throttle only loose and not cramped, for example, to get signaled changes in the road conditions on the front wheel and the chassis of the motorcycle, but the impulse response is still transmitted to the throttle grip.
  • the throttle grip is used to change the throttle angle, so that the impulse response causes - although this is not desired in the described driving situations - the throttle angle is increased briefly and the high-dynamic engine with a, a step response similar moments nantrain responded.
  • an aggressive response of the motorcycle engine could be counteracted in the partial load range, for example, by a significant increase in the rotational inertia of the crankshaft of the motorcycle engine, such an approach would lead to unwanted sluggish engine behavior throughout the speed range.
  • Such an aggressive response of the motorcycle engine in the partial load range now occurs regardless of the shape of the throttle body. Decisive for this problem is the flap base angle described above, which is structurally conditioned and ensures that a sticking of the throttle body in the air duct is avoided due to the described geometric collision of the throttle body and air duct.
  • Throttle body is to be achieved that at low load conditions and low speeds, a swirl flow is formed, which should improve the cylinder filling in the low speed range.
  • Throttle body a cutout, which ensures a cylinder filling even when the throttle valve is closed.
  • a combustion air guiding device which has a throttle body, which also has a cutout, in order to be able to realize a tumble flow.
  • This document describes the problem that sticking of the throttle body in the intake air passage may occur if the throttle body is not mounted with high accuracy in the intake air passage.
  • the object of the present invention is to provide a combustion air guiding device for an internal combustion engine which ensures harmonic power development of the internal combustion engine equipped therewith and avoids the undesirable aggressive behavior of the internal combustion engine in the partial load range.
  • the invention now provides a Verbrennungs Kunststofff ⁇ hrungsvorraum for an internal combustion engine, with an air duct and a pivotally mounted within the air duct throttle, whose outer contour is complementary to the inner contour of the air duct, wherein the throttle has a throttle body, which is formed in a longitudinal section to the outer contour tapering ,
  • the throttle body can be arranged in a rectilinear region of the air duct, ie a region without, for example, a flow disturbing step-shaped heel in the air duct and the throttle body is formed in a longitudinal sectional view that it is tapered in the direction of the outer contour.
  • the area of the throttle body that abuts against the inner peripheral wall of the air duct when closing the throttle body is made less thick than the remaining area of the throttle body, for example, the inclusion of a shaft for actuating the Throttle body serves.
  • valve base angle ie the angle
  • the inventive configuration of the throttle body with the outer contour tapering training now ensures that the valve base angle or throttle starting angle compared to the corresponding angle in a known configuration with straight-line thickness of the throttle body to the outer contour out, can be significantly reduced, so that a unintended by the driver rotation on the throttle grip leads to a continuation of the soft and harmonious ride of the motorcycle, since otherwise adjusting abrupt increase in the output torque provided by the internal combustion engine fails.
  • the driver of the motorcycle wants to increase the provided output torque of the internal combustion engine, he will do so by active actuation of the throttle grip. The driver will no longer be annoyed by such an increase in the output torque since he intentionally causes this increase and he no longer the result of an unavoidable suspension reaction when driving over a Bodenabsatzes in the partial load range at low speeds, so for example when passing through a closed town.
  • the throttle body is formed to the outer contour towards symmetrically tapered.
  • the tapered region can pass from the outer contour of the throttle body inwardly into a region of largely constant thickness of the throttle body.
  • This tapered portion of the throttle body comes into contact with the inner circumferential wall of the air duct when the throttle body is closed, so that the problem of geometrical collision of the outer peripheral portion of the throttle body with the inner peripheral wall of the air duct with respect to the throttle angle occurs later than in the prior art throttle body configuration.
