Stirling Car Engine Model Miniature External Combustion Power Exquisite Physics Science Kit for Experimental Gift Model Collection

Specification: Item Type: Stirling Car Engine Model Material: Zinc Alloy Size: Approx. 15.8 x 11.4 x 9.5cm / 6.2 x 4.5 x 3.7in(Product size is manually measured, it is only for reference.) Purpose: Through Manual , You Can Observe the Entire Running Process of the Stirling Engine, Understand the Stirling Principle More Intuitively, and Broaden Your Interest in Learning Physics. Instructions Before Use： 1. Purchase Alcohol with a Concentration of 95%. the Alcohol with a Concentration Lower Than 95% Has a Low Combustion Value, Which May Cause the Engine to Fail to Operate Normally 2. Add About Two‑thirds of the Alcohol in the Alcohol Lamp (cannot Be Topped Up, It Will Overflow when It is Topped Up) 3. Then Ignite the Alcohol Lamp to Preheat the Heating Cylinder, About 2 Minutes, After the Preheating Time is Almost the Front End of the Trolley Shall Prevail; Turn the Flywheel Clockwise to Give the Engine an Initial Power, Otherwise the Engine Will Not Run (turn the Flame Larger and when You Turn the Flywheel a Little Harder, the Engine is Easy to Start) How to Use: Precautions and troubleshooting methods for the Stirling engine trolley model: 1, It is best to use in a windless environment (windy flame will be biased, combustion will not be able to add cylinders, resulting in engine not rotating) 2. Wind will be generated during the movement of the car, which will cause the flame to swaying, and the hot cylinder will not be heated. Sometimes the car will not move. This is a normal situation and is not an engine failure. (You can adjust the wick to the front appropriately) 3. Note that the glass pipe in the heating cylinder cannot touch the inner wall of the heating test tube, causing excessive friction and the engine will not rotate 4. Check whether each node is stuck. If stuck, the engine speed will be low or even cause the engine to fail to run 5.The wick of the alcohol lamp cannot touch the heating test tube, which will cause the heating test tube to rupture. 6. Do not add any liquid (water, oil, etc.) to the heating cylinder and power cylinder, otherwise the engine will not run due to excessive friction. 7. If the engine is running normally and the car cannot move, please check whether the wheel is stuck or there is debris on the wheel. 8. Note that the car should be handled with care, otherwise it will easily cause damage to fragile parts Safety reminder: Don't touch the heating test tube and surrounding metal parts when heating, it is easy to cause burns Package List: 1 x Stirling Car Engine Model 1 x Alcohol Lamp 1 x Blue Alcohol Lid 1 x Alcohol Cotton 1 x Screwdriver 1 x Wrench 1 x Tweezers 1 x Elastic Rope 1 x User Manual
