Definitions

  • the invention is based on an intake tract for an internal combustion engine according to the preamble of claim 1.
  • the inventive intake system for an internal combustion engine having the features of claim 1 has the advantage that no additional mechanical components must be implemented in the intake manifold for the protection device, but the existing throttle is used, which is controlled intelligently for pressure reduction in reminduckundisme software.
  • the suction pipe must be for
  • the drawing shows a schematic representation of an intake tract for an internal combustion engine with a protection device in the case of reignitions.
  • a reciprocating piston 12 is arranged, which is guided axially displaceably in the cylinder jacket 111 and drives a crankshaft via a connecting rod 13.
  • the cylinder head 112 has at least one inlet opening 15 and at least one outlet opening 16.
  • the inlet port 15 is controlled by an inlet valve 17 and the outlet port 16 by an outlet valve 18. From the outlet opening 16, an exhaust nozzle 19 leads off, while at the inlet opening 15, a suction pipe 20 of an intake tract 21 opens.
  • the intake manifold 21 for supplying combustion air or an air-fuel mixture into the combustion chamber 14 of the combustion cylinder 11 has a throttle body 22 inserted in the intake manifold 20, a throttle valve 23, and an electromotive throttle actuator 24.
  • the throttle valve 23 is non-rotatably mounted on a Throttle valve shaft 25 which is pivotally mounted in the throttle body 22.
  • the throttle plate actuator 24 engages the throttle shaft 25 and is able to pivot the throttle valve 23 via the throttle shaft 25, whereby the clear cross section of the
  • Throttle valve 22 is released from the throttle valve 23 more or less.
  • a protective device 26 is arranged for the intake manifold 20 and for components arranged in the intake manifold 20, which responds to the intake manifold 20 during flashbacks and rapidly degrades a high pressure resulting from the restrikes in the intake manifold 20.

  • causes of the reignitions are also reverse rotations in the engine or a lean fuel-air mixture.
  • Refluxes also called misfires, preferably occur in different operating states of the internal combustion engine, such as engine stall, start abort, interruption of the fuel supply, etc.
  • the protective device 26 comprises a pressure sensor 27 installed in the intake manifold, which is arranged in the suction pipe section between intake valve 17 and throttle valve 23, and an evaluation unit 28, to which the electrical output signal of the pressure sensor 27 is supplied.

Abstract

L'invention concerne un conduit d'admission pour moteur à combustion interne qui présente au moins un tube d'aspiration (20), un clapet d'étranglement (23) disposé dans le tube d'aspiration (20) et un dispositif de protection (26) doté de moyens de détente de la pression qui règne dans le tube d'aspiration (20) et qui réagit en cas de retour de flamme dans le tube d'aspiration (20). Pour réaliser un dispositif de protection (26) économique à fabriquer, le clapet d'étranglement (23) est utilisé comme moyen de détente de la pression et est commandé de manière intelligente par un logiciel.
