The "PowerHouse" engine is a long stroke design
for medium to low speed operation. By having a long stroke, it
is capable driving a load such as a generator or pump at a leisurely
pace. It is made from bar stock and was designed to be as easy
to build as possible while retaining good looks. The frame and
base plate is from aluminum alloy plate. The cylinder, piston
and head are of cast iron bar stock; and the flywheel is of mild
steel. The engine is air cooled by fan (belt driven or electric),
although it will also operate without one. Spark advance/retard
is adjustable while the engine is running. The carburetor is an
easy to build type with adjustable speed control and an air cleaner.
The engine will run an hour or so on 2 ounces of fuel.
You will need a 6" lathe and a small milling machine with
a 6" diameter rotary table. This engine should be as easy
for beginners to build as any, and easier than most because the
engine frame is so simple.
The model runs from 500 RPM idle to around 1,800 RPM or so wide
open and the sound is real nice with the right exhaust pipe at
about 800 RPM.
The plans set consists of 16 sheets of quality laser printed CAD
drawings and 1 sheet of construction and assembly notes.
