Home of the see through engine

Here is the ‘Tân Glas’ a fully functional four stroke model engine, the bonus is that the cylinder is made of glass. Meaning that you can see the fuel exploding as the engine is working. Learn about the four stroke cycle by watching the valves open and shut and the spark plug ignite!

Control the mixture ratio of the fuel to air via the vapour carburetor venturi valve, you will see the explosion change from a vivid blue to a warm yellow as the fuel mixture becomes richer.

Observer the effect that ignition timing has on the power of the engine, an earlier ignition at high revs produces more power!

‘Tân Glas’ is the welsh sentence for Blue Fire reflecting the colour of the explosion on a well tuned engine!

Engine Features

Ignition Timing

With an adjustable timing lever the exact timing of the spark can be adjusted and it’s effect on performance observed. Simply move the timing lever down to advance the ignition and lift to retard.

Mixture Control

Control the fuel/air mixture via the venturi mixing valve on the fuel tank. Watch the flame change from blue to yellow as the mixture gets richer.

3d Printed

Built using 3d printed parts which include the camshaft, the blue plastic reflects the colour of the explosion of a working engine.
