Key Points:
1, Top Quality: A selection of excellent materials, the metal hot cylinder is beautiful and durable, and it does not wear at high speed for a long time. The metal bracket and the metal piston are firm and strong.
2, The galvanized aluminum flywheel and the rotating wheel are exquisite and beautiful, and the combination of texture and beauty. Besides, a 1.5W energy-saving light bulb, green and environmentally friendly.
3, The Stirling engine is powered by the expansion of the gas and the compression of the cold. 95% alcohol (self-prepared) should be used in the operation. Water, kerosene, gasoline, lighter oil, and liquor should not be added. Put the engine model in a horizontal position, take out the alcohol lamp, add about 2/3 of the alcohol to the
alcohol lamp, ensure the safety, ignite the alcohol lamp, the alcohol lamp heats the piston tube, and the dry air expands to generate power, which drives the flywheel quickly. Rotate to light the bulb, the whole process is quieter.
4, Entertaining and learning, through hands-on operation, you can observe the entire engine power generation operation process, more intuitive understanding of the principle of steam power generation, and deepen your interest in physics (this principle will be learned in the physics book of junior high school).
