Experimental Study on Diesel Particulate Filter Strategy for Generator

Abstract

Environmental substances emitted by diesel engines are fatal to humans. In particular, PM2.5 penetrates deep into the lungs, providing the cause of lung cancer. Recently, the Euro 6 regulation is proposed and regulated to reduce the emission source emitted from automobiles, but due to the increasing number of vehicles, it is only suggested as a temporary measure. Not only the pollution sources emitted from automobiles, but also the increase of fine dust emitted from thermal power generation or fine dust introduced from outside by wind is very serious. In addition, the generation of fine dust in narrow spaces, for example subways, has a serious effect on human activities. Although research and development is conducted to collect such fine dust, it is not easy technology in reality. Currently, the fine dust collection technology is collected through the filter, but the collection performance depends on the pore size of the filter. The smaller the pore size, the higher the collection performance, but seriously affects the engine performance because the back pressure increases. Therefore, it is important to optimize the pore size, structure or material of the filter to minimize the influence on the back pressure. In addition, if the back pressure increases due to the filter, the engine performance is deteriorated, and a regeneration device that removes the collected PM is required. Such a filter regeneration device is an essential device especially for automobile engines. This paper aims to develop a technology to apply metal diesel particulate filter to a heavy-duty diesel engine for commercial generators to secure the optimization technology for occurred back-pressure satisfying emissions (PM, CO, HC) environmental regulations for regeneration strategy of diesel particulate filter in near future.
