However, methanol has great differences from gasoline in physical and chemical properties, and the differences cause that the content of methanol in the methanol gasoline is relatively low, and the application of the methanol gasoline on automobiles has the following problems:
(1) the number of carbon atoms and hydrogen atoms in methanol molecules is different from that of gasoline, and the methanol molecules contain oxygen atoms, so that compared with the gasoline, the fuel cannot be ignited due to the fact that the concentration of the mixed gas is too lean under the condition of the same engine air inflow;
(2) the latent heat of vaporization of the methanol is 3.6 times that of the gasoline, and the high latent heat of vaporization and the lower vapor pressure cause the difficulty of cold start of the engine;
(3) methanol has swelling effect on non-metal materials such as plastics and rubber, and has corrosiveness on metal materials such as lead, tin, aluminum, copper and iron.
Therefore, the methanol gasoline used on the common gasoline engine needs to increase the fuel injection amount, increase the injection pulse width and replace the equipment or adjust the parameters of the traditional gasoline engine so as to use the methanol gasoline as the replacement fuel.
