Mechanical systems wear or change over time. Data collected over a system's life can be input to statistical learning models to predict this wear/change. Previous work by the inventors trained a flexible empirical regression model at a fixed point of wear, and then applied it independently at time points over the life of an engine to predict wear. The embodiment disclosed herein relates those wear predictions over time using a time evolution model. The time evolution model is sequentially updated with new data, and effectively tunes the empirical model for each engine. The combined model predicts wear with dramatically reduced variability. The benefit of reduced variability is that engine wear is more evident, and it is possible to detect operational anomalies more quickly. In addition to tracking wear, the model is also used as the basis for a Bayesian approach to monitor for sudden changes and reject outliers, and adapt the model after these events.

A multifuel internal combustion Stirling engine is described, wherein a compressor piston and a displacer piston reciprocate, within a common cylinder, to enclose a variable air volume, and a variable burned gas volume. Motion of these two pistons, creates a power producing cycle, of compression, combustion, expansion, and scavenge, wherein the burned gases do not contact those cylinder portions over which the compressor piston moves. In this way low engine wear can be obtained when using fuels such as coal, which produces abrasive particulates in the burned gases. A multifuel internal combustion engine of this invention can be readily adapted to operate on a wide variety of fuels, such as, natural gas, diesel fuel, residual petroleum fuel, and coal. Widespread use of these engines would introduce economic competition between these now separately competing fuels. This is a clear route to national energy independence, since coal reserves greatly exceed petroleum reserves, nationally and internationally.

Lubricant compositions comprising an improved ashless organic friction modifier additive have been found to be capable of reducing both friction and wear. It has been found that mixtures of fatty-alkanolamides containing secondary hydroxyls on the amino alkyl substituent, such as amide mixtures prepared from bis(2-hydroxyporopyl)amine and mixtures of at least two different C_8-24 fatty acids, provide better oil solubility and friction reduction than alkanolamides with primary, hydroxyl functionality, such as amide mixtures prepared from di-ethanol)amine.
