In addition, its superior quality and exquisite appearance also make it a high collection value, which can be sent as a high-end. The alcohol lamp will heat the piston tube to make the dry air expands to generate power, and then turn the wheel by hand to make it rotate rapidly, and the lamp will light up. During operation, place the Stirling engine model in a horizontal position (best placed on the flat glass), inject alcohol into the alcohol lamp, ensure safety and turn on the alcohol lamp. Selection of high-quality materials, the body is made of zinc alloy and the bottom plate is made of aluminum alloy. Through hands-on operation, you can observe the entire process of Stirling engine operation, more intuitive understanding of Stirling principles, and deepen your interest in physics.
