Problems solved by technology

This technique for cleaning the DPF requires vehicle maintenance, which is time-consuming and laborious, and it is easy to break 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 porphyrin 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 a porphyrin metal complex, and can effectively solve the problem of passive regeneration failure of a diesel engine particulate filter (DPF) and reduce the number of times of active regeneration, so that the effects of maintaining the DPF, saving oil and reducing the number of times and cost of maintenance are achieved.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, and in particular relates to a fuel additive containing a porphyrin metal complex and a preparation method and application thereof. Background technique [0002] With the implementation of increasingly stringent exhaust emission regulations in Europe, the United States, Japan, and China, the demand for diesel vehicle particulate filter DPF as an effective device to reduce particulate matter emissions will grow rapidly. On July 1, 2021, my country will implement the National VI emission standard nationwide, and the emission of particulate matter will be greatly tightened. In the past, the technical route of increasing the combustion temperature in the cylinder and the SCR system used in the National V emission stage can no longer meet the requirements of the particulate matter emission standard, and the particulate filter DPF must be installed to meet the emission requirements. [0003] DP...
