The invention discloses an alcohol-based fuel composite addition agent for an engine and a preparation method thereof. The alcohol-based fuel composite addition agent is a product compounded by carrying out 20-minitute backflow on the following components in percentage by volume ratio under the conditions of stirring at 40 DEG C and at a speed of 50r/min-70r/min: 60-70% of cosolvent, 10-20% of power improver, 5-10% of solubilizer, 1-5% of oxidation and corrosion inhibitor, 1-3% of anti-swelling agent and 1-2% of clearing agent. By utilizing the method, the blended product is not layered when encountering water, and has the advantages of good phase stability, no emulsification, wide buffer index and capability of keeping material clarified and transparent after the clearing agent is introduced; and the quality of an oil product is approximate to that of commercial vehicular NO.93 and NO.97 unleaded gasoline, the starting can be conducted at high temperature and in winter, the preparation method is simple, and the environmental pollution is less. |
