Tailoring of Lubricant Formulations to Localized Power Cylinder Wall Conditions
https://dspace.mit.edu/bitstream/handle/1721.1/98583/921140910-MIT.pdf;sequence=1
Pro...it's "fresh", and not relying on "old papers as gospel".
Con...it's a thesis, which apparently can't be trusted.
Con...there's modelling, which apparently can't be trusted either.
IMO...
Has some great data and correlations, viscosity, wear, and the optimisation of wear and usable life as a design parameter.
Recommends J300 be rewritten (a different take on it to mine).
Has an interesting twist on volatility in the top ring area, volatility increasing the localised viscosity in the top ring area...have posted papers before showing that additive concentrations in the top ring area are increased due to volatility, so more adds plus more viscosity is probably beneficial in that zone.
Contains surface roughness and ring wear predictions/measurements for calibration.
Has a newbie error in the HTHS description, same error spent a decade in 101.
Suggests compartmentalising lubricants for future engines (whodathunkit??)
It's certainly worth a read.
