Gasparin V12 CO2 Model Airplane Engine
Purchased from http://www.ministeam.com. This is a beautiful desktop version of a CO2 powered airplane V12 engine. This most probably the smallest V12 engine in the world. This engine is hand made in Europe. Only 100 of them will be made. G63V12 Bore: 4.0mm, Stroke 5.0mm, Stroke Volume 12 x 62.80 mm3, Weight 108g This engine is absolutely beautiful to look at and watch run. Size: 2 1/5 inches wide X 5 1/2 inches long X 4 1/2 inches high Assembled Ready-To-Run. Made in Europe Carbon dioxide motors have been around for a long time. They are expansion engines which work rather like a steam engine. The tank receives a charge of CO2 which is liquid at ambient temperature at a vapor pressure of about 850 psi. this boils in the tank to supply gas to the motor. In the Gasparin the inlet valve is a steel ball sealing under gas pressure in a nylon (delrin type) seat while the piston carries a central peg which lifts the valve as it approaches top dead center. Exhaust is through a ring of ports uncovered by the piston towards the bottom of the stroke. Gasparins spun alloy tanks, silver-soldered pipe work, connectors and the filler valves are all beautifully designed. The motors use a floating O ring to seal the piston, which works well. They also have a flexible joint between the gas supply pipe and the cylinder head. This seals in a silicon material and the feature is important because it allows the cylinder barrel to be screwed up and down on its threaded base in the crankcase. This allows adjustment of the valve timing and power output without disturbing the cylinder head gas seal.
Maier Butane Powered Model Engines
http://www.ministeam.com Purchased from The Great Toy Steam Company LLC The two cylinder gas motor CLASSIC V2 has a distinct motion. Because of the large and heavy flywheel this motor also has a low RPM. The two cylinders mutually balance each other for a smooth operating engine. It is ealily started by turning the flywheel. The motor produces the typical Exhaust sound of V operated - motors. The movement and flow of the two cylinder is emphasized through the open design. The contrary parts, like the cross heads and valve poles form an interesting mechanical motion. Through the use of Propane or butane (lighter gas) as a fuel, only non toxic fumes are released and therefore this is an ideal "room motor". The open construction of the motor allows one insight on the mechanical workings. A comfortable sound is established through two long Exhaust pipes. This model motor is made of aluminum, brass and stainless steel. The engine runs on a 70% Butane 30% 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. Technical data: RPM 200 - 1500 RPM, running time ca 10 min, height: 240mm, width: 150mm, length: 180mm, weight 2.5 kg, flywheel diameter ca 123 mm, ignition: Piezo-crystal - high volt
