PSU Energy Institute Paper

This paper summarizes research activities on fuels and lubricants by two Penn State University groups.

In the Penn State microoxidation (PMSO) test, deposit formation induction time was 60 minutes or 120 minutes, respectively, for Silcosteel® layers of 900 or 1200 angstroms, versus 0 minutes for an untreated test coupon.

Single cylinder diesel engine pistons were Silcosteel® treated or untreated and evaluated in a 50-hour steady-state engine test. At the end of the test, the rings on the treated piston were clean, whereas the top ring of the untreated piston could not be removed intact, the treated piston was significantly cleaner than the untreated piston.
