Butane Gas Powered Model Engine Double Cylinder V2 With Piezo Ignition


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.Ministeam

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./Ministeam
