Problems solved by technology

Oxidizing and burning the particles trapped in the DPF is a common DPF regeneration method, but this method is easy to cause thermal damage to the filter body
And most of the particles produced by lubricating oil additive packages and engine wear metals cannot be removed by oxidative combustion. Over time, these particles accumulate, block the DPF pores, reduce the particle capture capacity of the DPF, and at the same time, cause exhaust The back pressure of the trachea increases, the fuel consumption increases, and the power decreases, which may even cause the DPF to be burned and scrapped, resulting in serious environmental pollution and economic loss for replacing the DPF

Abstract

The invention discloses a diesel DPF cleaning regenerating agent and application thereof. The diesel DPF cleaning regenerating agent comprises a solubilizer, sodium lignosulphonate, sodium salicylate,a carbon deposit dissolving agent, a dispersing agent, a wetting agent, a surfactant, rust inhibitor and water; the diesel DPF cleaning regenerating agent is applied to the regenerating process of acarbon deposit-blocked DPF system. The diesel DPF cleaning regenerating agent has the advantages as follows: the diesel DPF cleaning regenerating agent not only has an extremely good cleaning effect,but also is safe, environment-friendly and pollution-free; when the diesel DPF cleaning regenerating agent is applied to the regenerating process of the diesel DPF system failing due to carbon depositblockage caused by poor fuel quality and incomplete combustion, carbon deposit, soot, colloid, oil sludge and other blocking substances in DPF pore passages can be safely and efficiently dissolved, dispersed and cleaned, so that the maintenance or replacement cost of the blocked DPF is reduced, the fuel consumption of a diesel is reduced, the engine power thereof is restored and the DPF tail gaspurifying effect is improved.

Description

technical field [0001] The invention belongs to the field of cleaning and regenerating agents, in particular to a cleaning and regenerating agent for diesel engine DPF and its application. Background technique [0002] Diesel vehicles have the advantages of low fuel consumption, high torque output, and wide power coverage, and are widely used in transportation and construction machinery. With the tightening of automobile emission regulations, diesel vehicles can only meet the strict emission regulations in the future by using after-treatment devices. The emissions of HC, CO, and NOx in the exhaust of diesel vehicles are less than those of gasoline vehicles. The disadvantage is that the emission of soot particles in the exhaust is higher than that of gasoline vehicles, even dozens of times higher. The solid pollutants emitted by diesel engines are mainly particulate matter, which is composed of dry soot (SOOT), soluble organic fraction (SOF), a small amount of sulfuric acid ...
