Description

The workings of an engine are clearly explained
through observing this representation four stroke
petrol engine. Modeled after a typical air cooled
engine, the operation of the valves is clearly evident
with the cams being driven by a gear train from
the rear of the main crank. A simulated spark plug
uses a small lamp to indicate the firing point and a
cross section of the carburetter is shown. Mounted
on a base, the engine provides screw terminals for
connection to a 3V battery.
Size: 8 1/4” x 8 1/4” x 14 1/2”.
