The sole known surviving example of a late 1945 American diesel which featured variable compression using an eccentric crankshaft bearing. This 0.34 cuin. (5.57 cc) unit is the first model diesel known to have been made by an established American manufacturer, in this case Jim Brown, who produced the Thermite range in Oakland, California from 1941 until late 1945 before becoming involved with the Vivell range. The engine runs really well, developing around 0.180 BHP @ 5,900 rpm. An article discussing this engine in depth may be found on the late Ron Chernich's "Model Engine News" (MEN) web-site.
