Problems solved by technology

Accordingly, there is an unmet need for systems and methods that test used oil at, say, 150 days of service and predict based on spent oil analysis which units should be changed at, say, 184 days and which units can safely continue to, say, 276 days without an oil change

Abstract

A system, a method and a computer program to predict a portion of used lubricant in an engine that is to be drained and replaced by fresh lubricant based on an analysis parameter value that is measured in a sample of used engine lubricant from the engine. The system includes a first input that receives the analysis parameter value from the used lubricant and stores the analysis parameter value in a memory of a processor. A second input receives an analysis parameter threshold value for the used lubricant at the end of a service interval and stores the analysis parameter threshold value in a memory of the processor. A determiner predicts a future analysis parameter value of a mixture of used and fresh lubricant at the end of the service interval based on the analysis parameter value, and the analysis parameter threshold value.

Description

[0001] related application [0002] This application is a continuation-in-part of application Serial No. 13 / 363,433, filed February 1, 2012, now pending. technical field [0003] The present disclosure relates to systems, methods and computer programs for determining the availability of lubricating oil and when to replace all or part of the lubricating oil in, for example, engines, power transmission equipment, turbines, generators, motors, and the like. Background technique [0004] Engines (or motors) are designed to convert a form of energy (such as, for example, fuel combustion, electricity, nuclear reactions, etc.) into mechanical energy, such as, for example, mechanical motion. For example, an internal combustion engine converts fuel combustion energy into motion energy. These engines typically include one or more combustion chambers that contain and confine the combustion of a fuel (eg, fossil fuel), which allows the resulting high temperature and pressure gases to e...
