Description

Car DPF Washer

The present invention relates to a DPF cleaning apparatus for a vehicle, and more particularly, to a DPF cleaning apparatus for a vehicle that can completely remove particles stacked inside the DPF by providing strong air pressure and water pressure to the exhaust port side of the DPF removed from the vehicle. It is about.

In general, the exhaust side of a diesel vehicle engine has components for purifying the exhaust gas and discharging it into the atmosphere. Among them, graphite contained in diesel fuel is collected inside the engine, and when a certain amount is collected, it is heated to a high temperature (500 degrees Celsius or more). There is a diesel particulate filter (DPF) to burn graphite and release it to the atmosphere.

The DPF is a device for forming particulates such as ceramics and metals in a honeycomb structure, and having a structure in which the microtubes communicate with each other (cross section) to filter particulate matter such as smoke.

If the filtrate accumulates due to the structure and principle of the filter, it should be removed (DPF regeneration) .In theory, if particulate matter such as a certain amount of soot accumulates inside the filter, it is forcedly burned by the heat of the exhaust gas to filter it. The remaining amount of the filtrate accumulated inside is reduced and removed to eliminate the clogging of the filter.

In more detail, when soot collects in the DPF, a difference occurs in the pressure of the inlet and the outlet of the DPF because the soot blocks the inside of the microtubule.

When the pressure at the inlet of the DPF is higher than a predetermined value, the ECU (Electronic Control Unit) instructs more fuel to be injected, and burns and exhausts soot collected in the DPF by the injected fuel to discharge the pressure difference between the inlet and the outlet of the DPF. Eliminate

However, if the vehicle is traveling at a low rpm (eg 2000 rpm or less), at low speeds, even if additional fuel is injected, the heat does not generate enough to burn off soot, and the driving is repeated such as turning off the engine after a short distance. Will work, but soot in the DPF will not burn properly.

As a result, the pressure difference between the inlet and the outlet of the DPF does not decrease significantly, and the DPF is operated again in a short period of time, and fuel is further injected, thereby increasing the amount of engine oil by continuously mixing diesel oil with the engine oil. .

Ideally, if you drive for a long time at high rpm (e.g. 2000rpm or higher) on the highway, the exhaust gas is completely burned and the operating cycle of the DPF is long. The incoming phenomenon can be significantly reduced.

Particulate matter such as residual soot, which is not burned during self-cleaning or after combustion, continuously accumulates inside the filter to obstruct the discharge of the filter, which causes the emission of exhaust gas to be not smooth. There was a problem that causes the failure of the catalyst installed in the front of the filter due to the engine output degradation, engine mismatch and high heat generation.
