Embodiment Construction

[0043] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, a person of ordinary skill in the art can understand that, in each embodiment of the present invention, many technical details are proposed for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed by the claims of this application can be realized.

[0044] The first embodiment of the present invention relates to a smokeless diesel. The smokeless diesel is composed of dimethyl carbonate, multifunctional compound additives, ordinary diesel or Fischer-Tropsch clean diesel, and the weight percentages of the dimethyl carbonate, multifunctional compound additives, ordinary diesel or Fischer...

Abstract

The invention relates to the field of fuels, and discloses smokeless diesel oil and a preparation method thereof. The smokeless diesel oil comprises 70-95wt% of common diesel oil, 2-25wt% of dimethyl carbonate and 0-10wt% of a multifunctional compound additive. According to the smokeless diesel oil provided by the invention, particulate matter emission in the using process of means of conveyance (comprising various motor vehicles and ships) taking diesel oil as a fuel and machinery for engineering, mining and agriculture and forestry taking diesel engines as power can be greatly reduced or even eliminated without affecting other emission indexes. The smokeless diesel oil is clean and environment-friendly diesel oil, and is simple and convenient and feasible. The fuel system of the diesel engine needs not to be changed.

Description

Technical field [0001] The present invention relates to the fuel field, and particularly to diesel technology in the fuel field. Background technique [0002] Diesel is an important liquid fuel, which is widely used in various motor vehicles, ships and engineering, mining and agricultural and forestry machinery. Data from the "China Statistical Yearbook 2011" shows that my country's diesel consumption reached 138 million tons in 2009, accounting for 64.4% of the total 214 million tons of domestic three types of refined oil (gasoline, kerosene and diesel) consumption. Diesel has become my country's consumption The largest volume of refined oil. [0003] Diesel engines have the advantages of large power, high efficiency, wide power range, high safety and good fuel economy. However, diesel engines emit a lot of harmful substances when they are running, causing serious pollution to the environment and endangering human health. Compared with gasoline engines, diesel engine exhaust emi...
