t is disclosed herein a new method for filtering used natural, semi-synthetic, or synthetic oil utilised in internal combustion engines, which method consists in the in-series utilisation of the following filtering elements: inert paper filter 1, organic filter 2 from shavings, stirring element in special stepwise arrangement 3, chemical filter from ion-exchange resins 4, and arrangement composed of variable geometry lamellae for removing bubbles. The used oil, after its passing through said arrangement removing scrapings, burnt oil, mud, colour or whatever other substances making the oil be unsuitable and damaging for engines, recovers all the physiochemical characteristics of unused oil. |
