Problems solved by technology

This technique for cleaning DPF requires vehicle maintenance, which is time-consuming and labor-intensive, and it is easy to punch through the wall-flow micropores in the DPF, resulting in a decrease in the filtration efficiency of the DPF.
Chinese patent CN104845682A discloses a fuel catalyst for an automobile internal combustion engine. The catalyst is composed of tourmaline, alumina, iron oxide and cerium oxide. The role of removing carbon deposits, but aluminum oxide, iron oxide, cerium oxide, etc. are all particles of about 250 μm, which cannot be dissolved in fuel and are not mentioned in the application of DPF particle filter regeneration
Although the particle size of the catalyst is below 5nm, it is still insoluble in fuel and the nanoparticles are easy to agglomerate, which affects its use

Abstract

The invention discloses a fuel additive containing a crown ether metal complex as well as a preparation method and application of the fuel additive. The fuel additive is prepared from components including solvent oil, an amine detergent and the crown ether metal complex, and the fuel additive containing the crown ether metal complex can effectively reduce the balance point temperature, remove engine carbon deposition, effectively solve the problem of passive regeneration failure of a diesel engine DPF particulate filter, improve the regeneration efficiency of a diesel engine, and improve the regeneration efficiency of the diesel engine. The number of active regeneration times is reduced, and the regeneration mileage is prolonged, so that the effects of maintaining the DPF, saving oil and reducing the maintenance times and cost are achieved; besides, the fuel additive disclosed by the invention can be conveniently added into a fuel tank during refueling, can be uniformly mixed with fuel, and can be kept stable for a long time after being mixed, so that the fuel additive disclosed by the invention has good solubility in the fuel.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, and in particular relates to a fuel additive containing crown ether metal complexes, a preparation method and application thereof. Background technique [0002] Diesel vehicle particulate filter DPF is an effective device to reduce particulate matter emissions. In the past, the technical route of increasing the combustion temperature in the cylinder and SCR system used in the National V emission stage can no longer meet the requirements of particulate matter emission standards, and a particle filter must be installed DPF can meet the emission requirements. [0003] DPF is a honeycomb ceramic sintered structure coated with precious metal catalysts. When the particles reach the DPF, they are intercepted by the pores, and the accumulated particles need to be burned to a certain extent, which is called regeneration. There are two methods of DPF regeneration, one is passive regeneration and t...
