Problems solved by technology

The common solution is to use dangerous open flame baking measures to alleviate the freezing of the oil circuit caused by paraffin crystallization. This is neither safe nor effective. For small vehicles, once frozen, there is no effective solution
[0003] At present, the problems of domestic diesel pour point depressants with similar functions are still few varieties, single function, large amount of addition, and most of the products are supplied to refineries as pour point depressant additives, which cannot be used directly by consumers, and have smoke elimination function Diesel antifreeze products are even more blank. The diesel smoke extinguishing antifreeze of the present invention not only fills this gap, but also has the effect of improving the label for low-quality diesel or non-standard diesel.

Abstract

The invention provides an environment-friendly type diesel smoke abatement and anti-freeze agent for purifying emission of diesel automobiles, which is prepared from cleaning and dispersing agent, anti-oxidant, alkyl nitrite or isopropyl nitrate or ethylene/vinyl acetate and high grade plane kerosene through high-shearing mixing and emulsion process. The invention can realize good intensified smoke abatement property and fluidity for diesel under low-temperature.

Description

technical field [0001] The invention belongs to diesel oil smoke suppressing and antifreezing agent. 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. The common solution is to use dangerous open flame baking measures to al...
