Ethanol engine using high-oxygen air-breathing

The utility model relates to an ethanol engine using high-oxygen air-breathing, which comprises an oxygen generating device, an oxygen storing device communicated with the oxygen generating device, and a carburetor for mixing the oxygen and ethanol, the carburetor is communicated with a cylinder of the engine. a blower arranged on the oxygen generating device is driven by the self power of the engine to convey the compressed air to the oxygen generating device. The oxygen-rich air produced by the oxygen generating device is input into the oxygen storing device, the oxygen-rich air in the pot is under the pressure, and is sent to the carburetor by a conveying pipe to be mixed with the ethanol to form the combustible ethanol gas mixture, the combustible ethanol gas mixture is inhaled into the cylinder by the self-absorption of the engine, thus the oxygen ratio in the ethanol gas mixture is improved, and the oxygen is supplied for the loss of the expansion air and the residual exhaust gas in the cylinder due to
