Abstract

The invention discloses a vehicle lead-free alcohol fuel which is characterized by consisting of the following matters according to weight portions: 100 portions of 70# light oil, 5 to 20 portions of benzene mixture, 20 to 50 portions of carbinol as well as 15 to 30 portions of ethanol. The vehicle lead-free alcohol fuel can be used as a fuel for replacing partial gasoline and can effectively ease the energy crisis; besides, the fuel in the invention does not contain lead; therefore, the pollution to the environment is less after the fuel is in use.

Description

technical field [0001] The invention relates to a novel vehicle fuel. Background technique [0002] Alcohols, such as methanol, have an oxygen molecular content of up to 50% (gasoline oxygen molecular content is O), and a combustion velocity of 52 m / s (MS) (gasoline 38M / S). The combustion calorific value of methanol is only half that of gasoline. Compounds (hydrocarbons, aromatic fuels) are mixed and burned in the cylinder. Due to the fast combustion rate of methanol, the average effective pressure of the engine cylinder is higher than that of gasoline. Therefore, with the same amount, the car runs the same distance as gasoline. Methanol is a product of coal and natural gas. 1 ton of methanol can be produced from 1.5 to 1.8 tons of coal, and the cost is much lower than that of gasoline. The price is only about 40% of No. 90 gasoline. Light hydrocarbons are the top oil of petrochemical refinery by-products, pentane and other products separated from natural gas condensate. D...
