Abstract

In this air induction module, the induction pipe has two separate induction pipe bodies ( 1, 2 ) with induction pipe sections that, together, form the induction pipes. The second induction pipe body ( 2 ), which can be attached to the cylinder head of the combustion engine, contains, in its induction pipe sections, a pulse charging valve ( 3 ) with an associated actuator. In addition to the pulse charging valves, the control electronics thereof can be integrated in the air induction module.

Claims (30)

1. An air induction module for a multi-cylinder combustion engine having pulse charging, with an induction pipe with individual induction pipes depending on the number of cylinders of the combustion engine, wherein the induction pipe comprises:

a first one-piece induction pipe body with an air collector and individual induction pipe sections and

a second one-piece induction pipe body with individual induction pipe sections which can be attached to the cylinder head of the combustion engine,

wherein the first and second induction pipe bodies are connected to one another by a flanged joint in such a way that their induction pipe sections together form the individual induction pipes of the induction pipe,

one respective pulse charging valve arranged with an associated actuator in the induction pipe sections of the second induction pipe body, and

the flanged joint between the two induction pipe bodies comprises an intermediate plate with through holes corresponding to the individual induction pipes which can be attached to the second induction pipe body by screw connections such that the intermediate plate holds the pulse charging valves with their actuators in the induction pipe sections of the second induction pipe body.

2. An air induction module according to claim 1 , wherein each pulse charging valve with the associated actuator forms a component part which during assembly of the air induction module can be respectively inserted in the correspondingly formed associated induction pipe section of the second induction pipe body.

3. An air induction module according to claim 1 , wherein the intermediate plate can be attached to the first induction pipe body by screw connections.

4. An air induction module according to claim 1 , wherein the second induction pipe body consists of a metal material or plastics.

5. An air induction module according to claim 1 , wherein the first induction pipe body consists of a metal material or plastics.

6. An air induction module according to claim 1 , further comprising an electronic control device for controlling the actuators of the pulse charging valves wherein the electronic control device can be attached to an air filter housing of the combustion engine or to the first induction pipe body or second.induction pipe body such that it is cooled by the fresh air flowing through the air induction module.

7. An air induction module according to claim 1 , further comprising an air filter housing, wherein the air filter housing can be attached to the first induction pipe body or to the second induction pipe body.

8. An air induction module according to claim 1 , wherein a throttle valve can be attached to the collector of the first induction pipe body.

9. An induction pipe comprising:

a first one-piece induction pipe body with an air collector and individual induction pipe sections and

a second one-piece induction pipe body with individual induction pipe sections which can be attached to a cylinder head of a combustion engine,

wherein the first and second induction pipe bodies are connected to one another by a flanged joint in such a way that their induction pipe sections together form the individual induction pipes of the induction pipe,

one respective pulse charging valve arranged with an associated actuator in the induction pipe sections of the second induction pipe body, and

the flanged joint between the two induction pipe bodies comprises an intermediate plate with through holes corresponding to the individual induction pipes which can be attached to the second induction pipe body by screw connections such that the intermediate plate holds the pulse charging valves with their actuators in the induction pipe sections of the second induction pipe body.

10. An induction pipe according to claim 9 , wherein the pulse charging valves are configured as poppet valves.

11. An induction pipe according to claim 10 , wherein the actuators of the induction pipe valves consist of solenoids.

12. An induction pipe according to claim 9 , wherein each pulse charging valve with the associated actuator forms a component part which during assembly of the air induction module can be respectively inserted in the correspondingly formed associated induction pipe section of the second induction pipe body.

13. An induction pipe according to claim 9 , wherein the intermediate plate can be attached to the first induction pipe body by screw connections.

14. An induction pipe comprising:

a first one-piece induction pipe body with an air collector and individual induction pipe sections and

a second one-piece induction pipe body with individual induction pipe sections which can be attached to a cylinder head of a combustion engine,

wherein the first and second induction pipe bodies are connected to one another by a flanged joint in such a way that their induction pipe sections together form the individual induction pipes of the induction pipe,

one respective pulse charging valve arranged with an associated actuator in the induction pipe sections of the second induction pipe body.

the flanged ioint between the two induction pipe bodies comprises an intermediate plate with through holes corresponding to the individual induction pipes which can be attached to the second induction pipe body by screw connections such that the intermediate plate holds the pulse charging valves with their actuators in the induction pipe sections of the second induction pipe body, and

an electronic control device for controlling the actuators of the pulse charging valves wherein the electronic control device can be attached to an air filter housing of the combustion engine or to the first induction pipe body or second induction pipe body such that it is cooled by the fresh air flowing through the air induction module.
