Description

DPF cleaning device and cleaning method for diesel vehicles {THE DIESEL PARTICULATE FILTER CLEANING EQUIPMENT AND METHOD FOR DIESEL VEHICLES}

The present invention relates to a DPF washing apparatus and a washing method for a diesel vehicle, which will be described in more detail to easily remove foreign substances accumulated in the DPF, which filters various foreign substances in the combustion gas from the engine of a diesel vehicle, while minimizing the risk of environmental pollution. The present invention relates to a diesel vehicle DPF washing apparatus and a washing method.

Internal combustion engines, such as gasoline and diesel, emit exhaust gas with the explosion of fuel, and high-pressure exhaust gas generates a loud noise like a racing car without a muffler, thus reducing the output of an ordinary vehicle. And a muffler was fitted.

In the past, only mufflers were used to reduce pressure, but diesel engines emit up to 100 times more harmful substances than exhaust gasoline engines as well as carbon dioxide and carbon monoxide. The International Cancer Research Institute (IARC) under the WHO has raised serious problems on June 12, 2012, when it raised the diesel engine exhaust gas from class 2A (presumed carcinogen) to class 1 carcinogen.

The micro-tubes made of ceramic and metal are formed into a honeycomb-shaped structure, and the micro-tubes are made in a cross section so that the micro-tubes cross each other, and the diesel particulate filter (DPF) that filters particulate matter in the exhaust gas is installed and collected. When a certain amount of the collected foreign matter is combusted to a high temperature (500 degrees Celsius or more) to be discharged to the atmosphere.

In other words, the structure and principle of the DPF is to filter foreign matters, and when the filtered foreign matters accumulate inside, the exhaust gas is forced to be burned and removed by heat of exhaust gas. The principle is to prevent this from falling, and the principle is that when the pressure at the inlet of the DPF is above a certain value, the ECU (Electronic Control Unit) instructs more fuel to be injected and burns the foreign matter gathered in the DPF by the injected fuel. By reducing the pressure difference between the inlet and outlet of the DPF.

However, if the vehicle runs at a low rpm and additional fuel is not generated to generate enough heat to burn off the foreign matter, the foreign matter gradually increases in an environment such as when the engine is repeatedly turned off after a short distance. The DPF is activated again to inject more fuel, increase fuel economy and reduce output.

The chemicals were passed through the inside to melt soot, pm, ash, etc., but the poisonous chemicals were well cleaned, but there was a problem of environmental pollution and internal damage of the DPF.

In addition, in the method of injecting and discharging the chemicals of the existing DPF cleaning equipments, there is a high possibility of spilling the chemicals on the floor during the process of injecting and discharging the chemicals by placing them on the floor or injecting them into a bucket. As the compressed air is injected at the same time while injecting, it must consume a large amount of water (20 L ~ 40 L), and the treatment of the discharged water causes cost increase and environmental pollution, and lifts and lowers heavy DPF. In the process, it was also a cause of injury such as the back of the mechanic.

Accordingly, there is a need for a washing apparatus and method for reducing environmental pollution generated during the DPF cleaning process and making the work easier.
