Abstract

The invention discloses an additive for reducing the emission of the charcoal smoke and harmful gas of a diesel engine and a preparation method thereof. The additive comprises a solute and a solvent, wherein the solute comprises the mixture of dimethyl carbonate and calcium acetate, and the solvent is ethanol or a mixture containing ethanol. With the adoption of the additive capable of reducing the emission of the waste gas harmful ingredients and charcoal smoke of a diesel engine and the preparation method for the same provided by the invention, the burning environment of burning diesel oil is improved from different aspects relative to the prior art, the limitation of the traditional single improvement means is broken, and cost can be reduced while combustion-supporting efficiency is ensured; simultaneously, a certain effect can be generated on the emission reduction of harmful ingredients in tail gas.

Description

technical field [0001] The invention relates to a diesel engine tail gas pollutant control technology, in particular to an additive capable of reducing the emission of harmful components and soot emissions of diesel engine exhaust gas and a preparation method thereof. Background technique [0002] With the widespread use of diesel engines, the pollution problems caused by diesel engine emissions cannot be ignored. Whether it is harmful gas CO, CO 2 , NO X , HC, or fine particles in the exhaust gas will cause various damages and disadvantages to the atmosphere, environment, and human body. [0003] In recent years, environmental protection departments at home and abroad have continuously promulgated new motor vehicle emission standards. According to a survey, more than one-third of the environmental testing of 113 key cities in my country did not meet the national Class II standard. In the study on the emission sources of respirable solid particles, nitrogen oxides, and v...
