Crower's prototype, the single-cylinder diesel eight-horsepower
Steam-o-Lene engine, uses that heat to make steam and recapture some of
the lost energy. It runs like a conventional four-stroke combustion engine
through each of the typical up-and-down movements of the piston (intake,
compression, power or combustion, exhaust). But just as the engine
finishes its fourth stroke, water squirts into the cylinder, hitting
surfaces as hot as 1,500°F. The water immediately evaporates into steam,
generating a 1,600-fold expansion in volume and driving the piston down to
create an additional power stroke. The upward sixth stroke exhausts the
steam to a condenser, where it is recycled into injection water.
