Fuel Additives Effectively Improving Fuel Economy

Abstract

Enhanced fuel combustion within the combustion chamber of internal combustion engines which results in improved fuel economy is obtained by adding fuel additives to the gasoline or diesel. Consequently, the fuel additives reduce pollution of hydrocarbon in environment. The fuel additives are combination of aliphatic oxygenates, monocyclic aromatic compound, and petroleum ether. The aliphatic oxygenates may be methanol, acetone, or a mixture of methanol and acetone. The monocyclic aromatic compounds may be toluene, xylene, or a mixture of toluene and xylene. This invention further relates to the method that manufactures the fuel additives.
