Method of determining proportion of oil in gas stream

The method involves feeding the gas stream through a tubular conduit. The oil is taken from the gas stream, collected and its mass is determined. The flow volume of the gas is detected by measurement technology. The gas stream is a main gas stream. The oil in the main gas stream is taken away and collected by means of an electric filter (2). To determine the mass of oil taken from the gas stream is determined by weighing the oil containing part of the electric filter (2) and the collected oil. During the weighing, the oil containing part of the filter is decoupled from the rest of the conduit.

Valve in crankcase venting system, used to return intercepted oil to sump, is associated with float assuring reliable closure under unfavorable differential pressure conditions

The valve (14, 15, 16) is located below the oil (11) collection chamber (12), which it opens or closes. A device assists closure. The valve chamber includes a moving valve plate which opens or closes a valve opening (13) located below the oil collection chamber. The valve opens under a set static pressure caused by the presence of oil in the collection chamber. It shuts under ambient pressure, which exceeds that in the oil collection chamber. A float (22) located below the valve, is the device which assists shut-off. In its first position, it is spaced away from the valve. In its second position it is floated up by the oil arriving, until it rests against the valve plate and moves it into the closed position, hence shutting-off the valve. The float, a closed piston, is carried in a vertical, axial guide (18, 20). The plunger (23) it carries, works the valve. The return oil line (24) is below the float. In operation, should there be no differential pressure, and should oil flow into the ...

Adsorbent structures for removal of water and fuel contaminants in engine oil

Devices and methods for removal of condensed, blow-by contaminants with small molecular dimensions from the circulating lubricating engine oil of internal combustion engines, including automotive engines, with a positive crankcase ventilation system are disclosed. These condensable blow-by contaminants include water, alcohols and hydrocarbons with preponderantly seven or fewer carbon atoms. A macroporous structure comprising alumino-silicate particles with micro-pores is at least partially immersed in the circulating oil. The micro-pores are sized to adsorb the small, condensed, blow-by, contaminant molecules but not the larger oil molecules. The particles may be multi-layered, with an inner layer adapted for adsorption of polar molecules. Adsorption is most extensive at lower oil temperatures and decreases as the oil temperature increases. Thus at low temperatures the contaminant molecules may be adsorbed, removed from the oil and temporarily stored in the micropores. At high temperatures some of the contaminants will desorb and be re-incorporated in the oil. The desorbed contaminants will be carried with the higher temperature oil into the engine crankcase where they may vaporize and be removed by the engine positive crankcase ventilation system.

Blowby gas treatment device for internal combustion engine with supercharger

Disclosed is a blowby gas treatment device for an internal combustion engine with a supercharger, the blowby gas treatment device comprising: a fresh air introduction passage wherein one end of the fresh air introduction passage is connected to an upstream side of the supercharger and the other end is communicated with a crankcase of the internal combustion engine; a first blowby gas passage wherein one end of the first blowby gas passage is connected to a venturi part provided in an upstream side of the supercharger in the intake passage and the other end is communicated with the crankcase; a first check valve being interposed in the fresh air introduction passage and preventing a flow from the crankcase side to the intake passage side; and a second check valve being interposed in the blowby gas passage and preventing a flow from the intake passage side to the crankcase side.

OIL SEPARATOR UNIT

An oil separator unit including an upstream member having an opening through which the blowby gas passes, a downstream member having a hit portion hit by the blowby gas, and a porous member trapping the oil mist contained in the blowby gas that has passed through the through hole. The upstream member includes an upstream surface facing a first surface of the porous member and a pair of recesses formed in substantially U-shapes along circumference portions in both end sides on an upstream surface of the upstream member, and the downstream member includes a pair of flange parts formed in substantially U-shapes so as to fit in the pair of recesses. 1. An oil separator unit configured to separate an oil mist contained in a blowby gas generated in an internal combustion engine , comprising:an upstream member disposed on an upstream side in a flow direction of the blowby gas and having an opening through which the blowby gas passes;a downstream member disposed on a downstream side in the flow direction of the blowby gas and having a hit portion hit by the blowby gas; anda porous member including a first surface facing the upstream member and a second surface facing the downstream member and formed in a substantially rectangular shape with a predetermined thickness so as to trap the oil mist contained in the blowby gas that has passed through the through hole, wherein an upstream surface facing the first surface, and', 'a pair of recesses formed in substantially U-shapes along circumference portions in both end sides on the upstream surface, and, 'the upstream member includes'}the downstream member includes a pair of flange parts formed in substantially U-shapes so as to fit in the pair of recesses.2. The oil separator unit according to claim 1 , whereinthe downstream member further includesa downstream surface facing the second surface, anda connecting part extending along the flow direction of the blowby gas that has passed through the opening and having a first end ...
