Hot Air double Cylinder Stirling Engine Generator Physics Popular Science Production Invention Collection Toy

Aerodynamics are rich in knowledge of physics, single cylinder combustion engine.

Engine principle is intuitive, educational toys, teaching experimental equipment can

effectively cultivate children's interest in learning can also be used for classroom

teaching, more intuitive and easy to understand.

Description:

Name: Double Cylinder Engine Model

Material: Aluminium alloy, glass

Colour: Silver gold

Size: 160x87x110mm

Instructions:

The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.

The packing bag of alcohol lamp cotton wear into the metal cap lamp.

Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.

Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.

Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.

Note:

This engine is perfectly for kids over 12 years old.

There will be the operation of steam,when the steam too much, the engine will stop working,

inside and outside the needle often set aside to reduce friction

Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked, can be bonded with glue.

The alcohol lamp wick do not touch the glass, do not get too tight ring

Pulling the piston connecting rod can not be forced the front end, because the front

end is easy to break
