Abstract

The invention discloses a device for purifying exhaust particles of internal combustion engines with flexible and adjustable working parameters. The first filter hole plate and the second filter hole plate are arranged alternately in parallel, at least two edges of the first filter hole plate are fixedly connected with the cylindrical body, and the second filter hole plate has and only the first edge passes through the deformation member and the cylinder The shaped body is fixedly connected, the first filter hole plate and the second filter hole plate are made of the same material and are provided with filter holes, and the deformation member deforms as the temperature rises so that the first filter hole and the second filter hole overlap in the length direction of the cuboid structure. From small to large. The invention has the flexible and adjustable flow area to adapt to different load states of the internal combustion engine and can have a self-cleaning function.

Description

technical field [0001] The invention relates to an exhaust particulate matter purification device of an internal combustion engine, in particular to an exhaust particulate matter purification device of an internal combustion engine with flexible and adjustable working parameters. Background technique [0002] Particulate matter is the main pollutant emitted by internal combustion engines. Particulate matter is mainly composed of soot and ash. At present, filter devices are generally used to capture soot in the exhaust. When the soot accumulates to a certain extent, it can be realized by heating and burning. Purification purpose. The existing filter device is suitable for capturing most of the particles in the exhaust gas of an internal combustion engine, which has a fixed gas flow area and is designed to have a filter and capture effect on a wide range of particle sizes. However, the particulate filter will increase the exhaust back pressure of the internal combustion engin...
