Problems solved by technology

A common solution is to use dangerous open flame baking measures to alleviate the freezing of oil passages caused by paraffin crystallization. This is neither safe nor effective, and may even cause fires that endanger life and property. For small vehicles, Once frozen, only thawing with hot water is not ideal, and it takes a long time and wastes energy
[0003] At present, the problems of diesel pour point depressants with similar functions are still single function and large amount of addition, and the products are supplied to refineries as pour point depressant additives, and consumers cannot directly use them.

Abstract

The invention relates to the technical field of petrochemical engineering, in particular to an emission reduction diesel antifreezing agent. The emission reduction diesel antifreezing agent is prepared from, by weight, 20-35 parts of polymethacrylate, 10-20 parts of polyethylene glycol, 10-18 parts of alkyl glycoside, 5-12 parts of dimethyl ether, 8-18 parts of antioxidant and 7-17 parts of octane value promoter. The emission reduction diesel antifreezing agent can be kept in continuous intensified combustion, condensation point and cold filter plugging point of diesel can be lowered remarkably, the diesel is prevented from being frozen at low temperature, parts are cleaned, smoke abatement effect is improved, and exhaust gas emission is reduced.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to an emission-reducing diesel antifreeze. Background technique [0002] Due to its low economic cost and strong power, diesel is widely used as engine fuel for trucks, buses, tractors, locomotives, ships, and various agricultural, construction, mining, and military machinery and equipment. However, due to the quality characteristics of diesel oil and the high-pressure injection combustion method, the emission of black smoke from diesel engines is very serious. How to solve the problem of serious emission pollution from diesel engines has become a hot topic worldwide. Due to the quality characteristics of diesel oil, its paraffin molecules tend to form eutectic crystals at low temperature in winter and crystallize to block the oil passage. This phenomenon has always troubled the majority of diesel oil consumers since the diesel oil was produced. A common solution is to use d...
