The main technology is the core mother liquor. The main technical route is to react "core mother liquor" with methanol to produce "energy saving agent", and then react "energy saving agent" with gasoline to become "low, medium, high ratio and M100 methanol gasoline series products and methanol fuel". Through the action of mother liquor, methanol and gasoline, through physical and chemical reaction and catalytic cracking function, mother liquor molecules are completely dissolved with methanol and gasoline molecules, and its properties are completely changed. The combustion flame and propagation speed is accelerated, the main combustion period and the ignition delay period are shortened, the high temperature and high pressure are formed instantaneously, and the thermal efficiency is dramatically improved, so that the heating value of gasification, acceleration and knock resistance are improved as a whole. Methanol gasoline can meet the requirements of automobiles in terms of its mutual solubility, water resistance, frost resistance, corrosion resistance, swelling resistance, gas resistance, wear resistance, etc., and it is prepared into high clean methanol gasoline and high clean methanol fuel with the same technical performance and physical and chemical indexes as traditional gasoline under normal temperature and pressure.
