This is what is left of the SES (Steam Engine Systems Corporation) first test engine from 1968-1972 donated to Tom Kimmel by Hal Fuller September 2013.   

The engine started as a French V-4 air cooled diesel made by Bernard, 90 mm bore and stroke.  The cylinders were kept with some of the fins being turned off and uniflow exhaust ports drilled into the cylinder all around the perimeter at near BDC with a heart shaped exhaust manifold clamped around the cylinder.

New heads were made from a block of iron with a poppet valve and steam chest.  A new camshaft was made and positioned in the block.

With the original crankcase and crankshaft came: 1 original diesel cylinder, 2, original diesel pistons, 4 modified diesel cylinders to uniflow steam cylinders, 4 new cast iron cylinder heads for steam, and a flywheel.   The steam pistons and connecting rods are missing.

The steam camshaft has a small range of adjustable cut-off.  The lead is decreased when the cut-off is increased using a lever to change a drive belt position.
The new steam engine installed in the 1974 Dodge Monaco and the coal mining Ramcar was designed and made by Ricardo in Shoreham, England.  It used the same bore and stroke, was a 4 cylinder in-line, and had two poppet valves for intake that had phase change to give a very wide ranging cut-off.  It was rated at 140 hp, 2500 rpm, 1000 psi, 1000 degree F steam and used about 1200 pounds of steam an hour.   Steam Engine Systems Corp.

    More parts of the SES test engine.  There is an adjustable camshaft that decreases the lead by changing the belt position.
