Abstract

Diesel particulate filters (DPFs) have been used in heavy-duty engine applications for nearly three decades. Recently, DPFs have also been used in off-road vehicles due to needs to reduce air pollution. Ceramic DPFs are characterized by light-weight, low pressure-drop, rapid regeneration, and excellent chemical resistance at high temperature. This article focuses on the development of a new ceramic DPF composed of Nano-materials for tractor engines. Functional tests showed that the filters absorb almost 10–20% of the pollutant gases of the engine. DPFs made from these new materials do not show cracking or melting under uncontrolled regeneration.

用于捕获柴油颗粒的纳米陶瓷过滤器

摘要

柴油微粒过滤器 (DPF) 已用于重型发动机应用近三十年来。最近,由于需要减少空气污染,DPFs 也被用于越野车。陶瓷 DPF 具有重量轻、压降低、再生快、高温耐化学性好等特点。本文重点介绍用于拖拉机发动机的新型纳米材料陶瓷 DPF 的开发。功能测试表明,过滤器吸收了发动机几乎 10-20% 的污染物气体。由这些新材料制成的 DPF 在不受控制的再生下不会出现开裂或熔化。
