Product details


.How to use: Put the engine model on the horizontal and inject alcohol into the alcohol lamp. Under the premise of ensuring safety, lit the alcohol lamp. The alcohol lamp heats the piston tube, and the dry air expands to generate power. At the same time, the flywheel is assisted by hand to drive the flywheel to rotate rapidly.

.Fuel: 95% alcohol should be used in the operation (not included), not water, kerosene, gasoline, lighter oil, liquor.

.The engine structure is designed reasonably, the novice can start very well without debugging, high power and high speed, and the speed range is 100-2000 rpm.

.Operation Theory: A stirling engine is a heat engine that operated by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there will be a net conversion of heat energy to mechanical work.

.The machine is maintenance-free and can be cleaned by simply injecting alcohol from the squirt port with a syringe and turning the flywheel. The lubrication method is drip lubrication.Fill the injection port with 0.5 ml with a syringe, fill it once before starting, and fill it once for 20 minutes.

.Wide Application: This model kit has a wide range of application as, great gift for Kids' science project, Physical/mechanical learning, teacherÀs Demo props on the class, birthday gift for friends, families, parents, kids, etc.

.Suitable for people over 14 years old
.Warm Tips: Be careful during operation. Do not touch the hot parts of the model

Fantastic Vacuum Engine - a real speed demon!

This engine worked right out of the box. I use 95% alcohol and this engine cannot wait to go! My video below is a cold start and in a few seconds the engine is running at high speed. This engine is heavy, solid and well built. The flywheel is very impressive and is not made of lightweight aluminum like many vacuum engines. The finish of the engine is great, I use "NEVR DULL" to keep it clean and shiny! I have purchased several different types of flywheels from Sterlingkit just to see how the engine runs differently. The crankshaft extends long enough that you can install a second flywheel. I lubricate all crankshaft moving parts with 3in1 light oil and it definitely helps. Squirting some alcohol into the cylinder between runs also help to keep it clean. Just an awesome vacuum engine! Everyone should have one!

A very impressive engine

This engine is very well made and runs great. It amazing to watch it run with just an alcohol burner as fuel. It took some adjusting to get it to work. I found that the "flap" covering the slot in the cylinder needed to be adjusted. A little trial and error got it running smoothly. I would definitely buy this again
