Definitions
- crankcase ventilation systems in which a line leading out of the crankcase branches into two lines, which then lead to a main ventilation point located in front of a throttle valve and to a secondary ventilation point located behind the throttle valve, are known, for example from US Pat. No. 3,364,910 a total of three separate lines required. Icing of both ventilation points, for example due to freezing condensate, is not prevented. In the event of icing, the crankcase cannot be vented. This contradicts legal requirements and leads to leaks due to the resulting crankcase overpressure, eg on crankshaft sealing rings.
- a throttle valve the icing of which is prevented by an annular channel through which cooling water flows and which runs in the throttle valve housing is known from DE-PS 29 49 096.
- the object of the present invention is to provide a crankcase ventilation, which ventilates the crankcase in the air intake tract in normal load operation as well as in coasting or idling operation of the internal combustion engine, and in which icing of the ventilation points in the air intake tract is prevented.
- this object is achieved by the characterizing features of claim 1. Further features which advantageously design the invention are specified in the subclaims.
- the advantages of the invention can be seen in particular in the fact that the crankcase is vented in a simple manner at all positions of the throttle valve, and that icing of these points is achieved with it by the arrangement of an annular channel through which coolant flows in the immediate vicinity of the throttle valve and the venting points and the throttle valve is prevented.
- only one line, usually in the form of a hose is necessary for the supply of the crankcase gases into the throttle valve housing. This reduces component costs as well assembly and service costs.
- the throttle valve housing can be produced in one piece with all connections.
- An internal combustion engine 1 is supplied with fresh air through an air intake tract 2 .
- the fresh air is first conveyed by the internal combustion engine 1 through an intake port 3 and an air filter 4 .
- the fresh air flows through a pipe section 5 and then through a throttle valve housing 6 , in which an adjustable throttle valve 7 is arranged.
- the fresh air then flows into an air collector 8 and from there through suction pipes 9 into the combustion chambers of the internal combustion engine 1 .
- the internal combustion engine 1 has a crankcase ventilation point 10 , from which a ventilation line 11 leads to the throttle valve housing 6 and is fastened there to a connecting piece 12 .
- the end of the connecting piece 12 located within the throttle valve housing 6 is closed with a disk 13 .
- the disk 13 has two channels 14 , 15 penetrating it, channel 14 opening into the main ventilation point 16 and channel 15 opening into the secondary ventilation point 17 .
- the main ventilation point 16 is located upstream in front of the throttle valve 7 , the secondary ventilation point 17 downstream behind the throttle valve 7 .
- the channel 15 and the secondary ventilation point 17 have a significantly smaller cross-sectional area than the channel 14 and the main ventilation point 16 .
- throttle valve 7 is open.
- the air flowing through the air intake tract 2 has a lower pressure than the gases in the crankcase of the internal combustion engine 1 .
- This pressure drop conveys the crankcase gases through the ventilation line 11 from the internal combustion engine 1 to the throttle valve housing 6 . Due to the larger cross-sectional area of the main ventilation point 16 , the crankcase gases predominantly flow through this ventilation point 16 into the air intake tract 2 and are mixed there with the fresh air flowing in and fed to the internal combustion engine 1 .
- the cross-sectional areas of the channels 14 and 15 are dimensioned in such a way that the volume of crankcase gases arising can be safely removed.
- the throttle valve housing 6 is closed by the throttle valve 7 which is transverse to the direction of flow of the intake air.
- the throttle valve 7 separates the main ventilation point 16 from the secondary ventilation point 17 . Since the internal combustion engine 1 continues to try to promote fresh air through the air intake section 2 and the throttle valve 7 blocks the air intake 2, 7 lying part of the air intake tract 2 creates a strong negative pressure in the downstream of the throttle valve. This negative pressure sucks the crankcase gases through the channel 14 to the secondary ventilation point 17 .
- the outlet area of the secondary ventilation point 17 is dimensioned significantly smaller than that of the main ventilation point 16 , since the amount of crankcase gases occurring in overrun or idling operation is correspondingly small.
- an annular channel 18 is arranged, which is concentric with the throttle valve 7 and runs at a short distance from the connecting piece 12 and the channels 14 , 15 .
- This channel 18 is connected via an inlet 19 and an outlet 20 to the cooling water circuit of the internal combustion engine 1 .
- a thermostatic valve 21 which is inserted with an air temperature sensor 22 into the pipe section 5 of the intake tract 2 , regulates the coolant supply as a function of and within certain limits of the intake air temperature.
- the arrangement of the venting points 16 , 17 in the vicinity of the channel 18 also advantageously prevents these venting points 16 , 17 from icing up.
- the channels 14 , 15 are inexpensive to produce in the disc 13 as bores.
- the connecting piece 12 can alternatively be made in one piece with the disc 13 as a casting. To reduce the assembly effort, in a further embodiment of the invention the connecting piece 12 can be produced in one piece with the throttle valve housing 6 and the disk 13 as a cast part.
