Abstract
A method to employ instrumentation to effectuate variation in lubricant flow rate or properties in response to actual engine conditions. Preferably, the present invention provides a method for the in situ monitoring of the lubricating oil's effectiveness in a two-stroke diesel engine by measuring the used lubricant's Fe content and fuel sulfur content with XRF technology and the used lubricant's BN with an IR measurement device, and for efficiently modifying the lubricant's properties and/or flow rate to the equipment in response to the actual wear or corrosion needs of the machinery or engine.
Claims8
A method for the modification of a system's base lubricant's flow rate and/or properties during engine operation comprising:
- a) Regularly monitoring, directly or indirectly, one or more engine condition parameters in an engine with one or more instruments selected from the group comprising XRF or BN measurement with IR spectra
- b) Calculating from said engine condition parameters an amount to vary the feed rate or modify the properties of the base lubricant to the engine
- c) Varying the feed rate or modifying the properties of the lubricant.
