Mô hình động cơ stirling mini có đèn LED

Feature: Galvanized aluminum promises durability. High temperature resistance and low temperature resistance. LED lights directly demonstrate the process of converting thermal energy into electrical energy. Instructions: -The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth.
