Abstract:
Elevated temperature liquid testing apparatus and methodology in which a thin film of test liquid and a reactant/control gas are provided about the top of a depositor member that is surrounded by a special mantle, for example, a substantially cylindrically walled glass mantle. As an oxidative engine oil test, it may mimic turbocharger conditions of a modern internal combustion engine. For example, employing moist air, the apparatus can test a thin film of engine oil for oxidation deposits at a predetermined temperature, say, 285° C., 290° C., or cycled between 285° C. or 290° C. and 320° C. or 330° C.

Claim (Index 8):
A method for testing liquid engine oil or other liquid as a test liquid for deposits formed at elevated temperatures under thin-film conditions, which comprises steps, not necessarily conducted in series, as follows:\n providing an apparatus for testing the test liquid for deposits formed at elevated temperatures under thin-film conditions, which includes a heatable sample reservoir; a test liquid placement volume; in the test liquid placement volume, a heatable deposit-receiving surface in a form of a rod having a generally helical guide or channel for the test liquid such that a thin film can be formed thereon, in which bulk flow and its inherent difficulties in effective diffusion of a gaseous reactant/control substance into the test liquid can be avoided, and diffusion can be ameliorated or eliminated as a substantially limiting factor when the test liquid is delivered to the heatable deposit-receiving surface by a thin film forming unit, with the heatable deposit-receiving surface in liquid communication with the test liquid placement volume; the thin film forming unit, which can deliver the test liquid to the heatable deposit-receiving surface as the thin film; a reactant/control gas delivery unit; and a supply of at least one reactant/control gas, which may or may not adversely affect the test liquid\u2014wherein the thin film forming unit and the reactant/control gas delivery unit are positioned in an upper reach of the test liquid placement volume so that both the liquid engine oil or other liquid as the test liquid; the supply of at least one reactant/control gas can be delivered about an upper reach of the heatable deposit-receiving surface, optionally, in addition to or in lieu of which, being delivered to the test liquid away from the heatable deposit-receiving surface in the test liquid placement volume; and a surrounding mantle spaced apart from the heatable deposit-receiving surface a distance substantially non-varying from top to bottom with respect to the heatable deposit-receiving surface; providing the test liquid, and heating it or maintaining its heat at a first temperature in the heatable sample reservoir; heating the heatable deposit-receiving surface to a second temperature; delivering the test liquid and the supply of at least one reactant/control gas about an upper reach of the heatable deposit-receiving surface for a predetermined time under elevated temperature, thin-film conditions at or about the second temperature; and checking for and/or assaying any deposit on the heatable deposit-receiving surface.
