Diesel oil quality improver for national III diesel oil

Abstract

The invention relates to a diesel oil quality improver for national III diesel oil. The diesel oil quality improver contains the following compounds in parts by weight: 12-18 parts of polyisobutylene succinimide, 24-36 parts of glycerol trinitrate, 8-12 parts of polyether amine, 8-12 parts of polyethylene vinyl acetate, 4-6 parts of dimethyl carbonate, 8-12 parts of sorbitol fatty acid ester and 16-24 parts of solvent oil. Compared with the prior art, the diesel oil quality improver has the advantages that the consumption of fuel can be lowered, the service life of an engine is prolonged, and the emission of PM2.5 (Particulate Matter 2.5) and gaseous pollutants can be simultaneously lowered, so that the diesel oil quality improver has an important practical value.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a diesel quality improver for national III diesel. Background technique [0002] At present, severe smog weather has become a major comprehensive problem facing our country. Fine particle (PM2.5) "explosion" in winter and spring has become the norm in many northern cities, seriously endangering people's health and hindering economic and social development. harmonious development. On the one hand, the harm of fine particles is the stimulating effect of its deposition in the alveoli, and on the other hand, it is the carrier effect of absorbing a large amount of toxic substances. The generation of smog is directly related to pollutants such as nitrogen oxides and fine particles emitted by motor vehicles. Among them, nitrogen oxides (NOx) emitted by diesel vehicles is close to 70% of the total automobile emissions, and particulate matter is more than 90%. Therefore, diesel engine emission reducti...

Problems solved by technology

Although it advertises that it has the effect of reducing emissions, its principle is still based on the difference in the decomposition temperature of isooctyl nitrate and di-tert-butyl peroxide in the diesel engine, which plays a role in timing the catalytic ignition of diesel in the engine. But it cannot effectively improve NOx emissions, and the impact on PM2.5 is not yet clear

[0004] In recent years, polyoxymethylene dimethyl ether has become a widely concerned diesel additive, which can reduce particulate matter emissions by increasing fuel oxygen content, but its production process is complicated and costly, and it cannot be widely used

In addition, some scholars use metal nanomaterials as additives to improve diesel engine emissions, such as cerium oxide and aluminum oxide, but the impact of the introduction of metal elements on PM2.5 remains to be further studied

Since the formation of particulate matter and NOx in the combustion process of diesel engines is mutually restricted, only the use of compound additives can achieve a comprehensive emission reduction effect. Although the relevant research was carried out earlier, it has not been practically applied.
