Problems solved by technology

The invention can improve the power of methanol gasoline and enhance the stability of methanol gasoline, but the aviation kerosene used has a high-carbon hydrocarbon mixture with a distillation range of 180-310°C, which is incompletely combusted in a gasoline engine and increases carbon deposits; The cerium nitrate metal compound, the combustion process will inevitably produce metal oxides and nitrogen oxides, which will be deposited on the surface of the combustion chamber, intake valve and spark plug, increasing engine wear and environmental pollution; the used methylal will produce polymer after combustion , block the porous carrier of the thre

Abstract

The present invention discloses a vehicle methanol gasoline composite additive. The vehicle methanol gasoline composite additive comprises 2-ethyl hexanol, ethylene glycol butyl ether, lanolin fatty acid isobutyl lanolate, methyl lanolate, polyisobutene amine, an antioxidant, and xylene. The additive does not contain metal compound which is detrimental to engine combustion, and can enhance the stability and cleaning performance of methanol gasoline, effectively inhibit corrosion on an engine combustion system by the methanol gasoline and alleviate swelling of rubber product parts by the methanol gasoline. 0.05-0.20% of the composite additive is added into the vehicle methanol gasoline, and the vehicle methanol gasoline can fully satisfy the use requirements of vehicle engines.

Description

Technical field [0001] The invention involves the field of vehicle fuel oil additives, especially a composite methanol gasoline composite additive. Background technique [0002] With the rapid development of the global economy, energy consumption has risen sharply, and huge fuel consumption has caused huge pressure on the increasingly exhausted oil energy sources. Energy security has become the most concerned strategic issue in the world.The rapid development of my country's national economy and the rapid popularization of automobiles have increased the national oil relying on 56.4%(2012), which has brought tremendous pressure on environmental protection.The application of vehicle methanol gasoline as a new type of environmental protection can greatly alleviate the national energy safety crisis.However, methanol replacing gasoline for gasoline engines will inevitably bring reactions that are not applicable. It is necessary to develop fuel additives that improve the performance of...
