The VW conversion engine uses the crankcase, crankshaft, connecting rods, wrist pins, cylinders, flywheel and clutch from a stock 1500cc VW engine. The engine uses a 7 % cutoff cam and as a result it is not self starting. This arrangement, however, provides a large expansion ratio that uses most of the available energy in the steam. The engine is fully condensing in 100 degree F weather and gets 18 miles per gallon of fuel.

Parts that must  be fabricated are cylinder heads, camshaft, cams and cam housing.  The camshaft is driven by a timing belt from the crankshaft. Only two of the four cylinders are used in the steam conversion. the  two steam cylinders provide the same number of power impulses per  revolution as the 4 cylinder gas engine.
 
 

Detail drawings are available for all the parts needed to construct the engine. In order to complete the steam power plant there is needed also auxiliaries such as a steam generator, centrifuge, right angle gear box, high pressure lube injection pump, centrifugal fuel metering pump, and electronic water pump controller.
