With the help of the flywheels, then a net conversion of heat energy to mechanical work. Mechanical work through small generators produce electricity to power a light bulb.
Can be used for teaching purpose.
What is the Stirling Engine?
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall.
How it works?
This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
Двигатель полностью выполняет свою учебно- познавательную функцию. Качество изготовления на высоте, внешний вид очень, как по мне, приятный.
Оси вращения крепятся через миниатюрные подшипники. Вращение всех узлов двигателя плавное и тихое. Сборка отличная, все чистое, никаких отпечатков пальцев, потеков масла, грязи и т.д. Просто идеально. Основные материалы – сталь, маховики дюраль, противовесы – латунь.
This is a vacuum engine. When properly adjusted it works well
On mine the round rod at the top, the one that moves the hole covering leaf type valve, needed to be adjusted. This can be done by holding the levers at the side with thumb and forefinger of one hand while moving the round rod slightly up or down. When moving the flywheel counterclockwise, a cliciking soind should be heard.
One needs to play with it by trial and error until the motor runs well. The hole in the front needs to be completely covered when in the lower position.
