Definitions
- the invention relates to a device for venting a crankcase an internal combustion engine with an arrangement for separating oil from the air to be discharged, which a blast wheel with blades and a Includes air outlet.
- Object of the present invention is therefore, a Crankcase ventilation with a particularly effective device for To provide oil separation. Even with a high ⁇ lbeetzschlagung the discharged air to prevent unwanted oil discharge effectively become.
- the device should be compact, only a few Consist of components and be cheap to manufacture and assemble.
- a device with the features of Proclaimed claim 1 wherein according to the underlying Idea the radially extending blades of the spinner in Sliding wheel axis extending in the direction of Lucasabströmstutzens the inlet opening of the Lucasabströmstutzens at least approximately coaxially is arranged to the blast wheel and the opening plane to Schleuderradebene is at least approximately parallel and the inlet side End portion of the Lucasabströmstutzens with the airabströmstutzen matter blade edges of the rotating blast wheel as close as possible Includes flow gap.
- the flow direction of the oil loaded blowby gases is thus the pumping direction and thus the spin direction of the opposite to deposited oil.
- the gap formed between the impeller and Heilabströmstutzen a width from 0.5 to 3 mm, in particular about 1 mm, whereby it is achieved that the vent flow, which is on its way towards Heilabströmstutzen flows through the gap, is subjected to turbulence, so that a separation of the inert oil compared to air to the Blades of the impeller takes place.
- blast wheel directly depends on the engine speed is drivable. That way is at any time a pressure build-up in the crankcase corresponding Ventilation guaranteed.
- the blast wheel on a camshaft of Internal combustion engine arranged, which in terms of function and installation space is particularly favorable.
- the blast wheel is thus in a four-stroke engine driven at half crankshaft speed. Higher speeds lead to better separation results, however, require a larger constructive effort.
- this is Impeller disc-shaped with arranged on a side of the disc Shovels are formed and the blade free side is one facing adjacent camshaft gear. It exists a special advantage in that the disc oil, which of the Camshaft gear driving chain is carried by, from Keeps air outlet pipe away.
- Impeller wheel oil catchment and / or ⁇ lleitvorraumen are provided, so that the spun-off oil is collected and returned.
- FIG. 1 shows a detail of a cylinder head 100 of a boxer engine in the section, whereby in particular the range of the crankcase ventilation with Oil separator is shown.
- a blast wheel 108 for Oil separation from the discharged from the crankcase 124 air arranged, which in a particularly simple manner directly from the Internal combustion engine speed dependent rotary drive of the centrifugal wheel 108 takes place.
- the blast wheel 108 is arranged at the shaft end, so that an air discharge nozzle 118, the inlet opening concentric with the Shaft axis of the shaft 112 is disposed with its outer edge 122nd with the blast wheel 108 includes a flow gap 120.
- the flow gap 120 has a width of 0.5 to 3 mm, in particular about 1 mm, the exact design according to the Flow rate and / or the oil content of the discharged air he follows.
- the spinner 208 is shown in detail in Figure 2 and has a disk-shaped body 230, which has a spacer collar 234 as well on the other side of the disk wings 232 (a, b ...); for fixing on the shaft 112, a bore 236 is provided.
- the blast wheel 108 is located with the Spacer collar 234 on the camshaft sprocket 110, so that the wings 232 (a, b %) of the inlet opening facing the Lucasab Industriesstutzen 118, thereby With rotating impeller 208 with the edge 122, the air gap 120 locked in.
- it is from the timing chain entrained oil through the disc-shaped body 230 of Air outlet 118 kept away.
- the crankcase breather is on a cylinder arranged in which the direction of rotation of the timing chain runs in such a way that the chain already entrained when the Mauwellenritzels Spent oil and so little oil to the camshaft sprocket and thus in the area of the crankcase ventilation is worn;
- this is a Cylinder with which the load strand downwards and the empty strand upwards runs, in the figure 1, the crankcase ventilation is the preferred cylinder shown, with the direction of rotation of the camshaft sprocket with the arrow 126 is indicated.
- the flow during the venting through the oil separation serving impeller 108 is shown by the arrows 102, 104, 106.
- the oil-laden air flows according to 102 in the direction of the gap 120, where very strong prevailing air turbulences, so that the airborne Oil fractions due to their higher inertia of the air movement not and can follow the blades 232 (a, b ...) of the rotating Knock down blower wheel 108, represented by the arrow 104; the now oil-free air flows according to the arrow 106 direction of Vent hose 114.
- the precipitated on the blast wheel 108 oil is thrown radially due to its rotation accumulates in space 116, optionally in the housing area radially outside the Blower wheel 108 collecting or flow guiding devices provided, to calm the oil flow.
