external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hydrogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and generate strong power.\u003cbr\u003eAs the external combustion engine, it avoid the explosion risk when traditional internal combustion engine working, in order to achieve a high efficiency, low noise, low pollution and low operating costs.\u003cbr\u003eThe biggest advantage of the external combustion engine is that the output and efficiency are not influenced by altitude, very suitable for high altitude areas.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eInstructions:\u003c\/b\u003e\u003cbr\u003ePut the engine model on the horizontal position, toggle the flywheel to see if it is smooth, if there is a strong sense of raw astringent, check the connection rod, whether the cylinder has oil and dust, and if so, please use toilet paper to erase. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.\u003cbr\u003eThe packing bag of alcohol lamp cotton wear into the metal cap lamp.\u003cbr\u003ePlease go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.\u003cbr\u003eAlcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.\u003cbr\u003eLed lights can be directly into the generator output interface, if not inserted, the exchange can

naturally.\u003cbr\u003eAfter the engine cools naturally, keep the engine out of the reach of small children.\u003cbr\u003eChildren in adults under the care of the use of the engine, so as not to burn

guardianship of parents.\u003cbr\u003eWhen heating, do not touch the tube of alcohol lamp tube, wick combustion will produce moisture, if touched, may lead to tube cracking.\u003cbr\u003eBoth ends of the connecting rod joint activities need to add regular oil lubrication, the piston can not refuel, otherwise it will not work the resistance.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage
