Butane Gas Powered Engine - Double Cylinder V2 with Piezo Ignition MM5

The engine is easy to start thanks to the piezo high voltage ignition system, two "ignition jets" and a large brass flywheel. Once running the engine produces the typical V-engine exhaust sound. The two cylinder motion sequence is especially accentuated due to the open construction design. The counter-rotating parts - pistons, crosshead and push rods - result in an intriguing mechanical interplay.

Through the use of Propane/Butane or Butane (lighter gas) as a fuel, only non toxic fumes are released and therefore this is an ideal "indoor engine".

This model motor is made of aluminum, brass and stainless steel. The engine runs on a 80% Butane 20% Propane mixture that can easily be purchased at a camping outdoors shop. This mixture allows the engine to run in the house with a window open. The spark plug is actuated by a piezo igniter.
