Abstract As part of the research concerning the development programs to identify automobile engines having low exhaust emission, one approach which is being investigated is the Rankine cycle which includes a reciprocating steam expander as the prime mover. For maximum engine performance, high temperatures and pressures similar to modern steam power plant practice are required. For these operating conditions, liquid lubricants for cylinder and inlet valve lubrication are a limitation. The report discusses the following concerning this research: Additional design analyses for lubricant wear which indicate the life for the graphite rings should be satisfactory; Planning for assembly of cost data on primary and alternate materials for both the crosshead piston and trunk piston designs; The Mobil synthetic hydrocarbon oil selected for use in the first single cylinder test; and evaluation of the tappet and cam damage during the motoring.
