Description

Stirling engines are unique heat engines because of their theoretical efficiency is almost equal to the theoretical maximum efficiency,
Called the Carnot cycle efficiency. The Stirling engine is heated by gas expansion, cold contraction generate power.

Description:
Name:Stirling Engine Hot Air Model
Material:metal,glass
Color:gold
Size:165x87x95mm
 
Overview:
-This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hyd rogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and strong power.
-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.
-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.
- 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.
 
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:
-There will be the operation of steam,when the steam too much time, 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 force the front end, because the front 
end is easy to break
