Abstract

The invention discloses a heavy-duty vehicle DPM tail gas after-treatment device and a heavy-duty vehicle. The device comprises a metering unit and a spraying unit; the metering unit comprises a first shell, a shut-off valve, an injection valve and a temperature and pressure sensor; the first shell is provided with an oil inlet, an oil outlet and an oil channel for communicating the oil inlet with the oil outlet; the shut-off valve is mounted on the oil inlet; the injection valve is arranged on the oil channel; the temperature and pressure sensor is arranged on the oil channel and is positioned between the shut-off valve and the injection valve; and the spraying unit is used for atomizing and spraying diesel oil supplied by the metering unit.

Description

technical field [0001] The present invention relates to the technical field of tail gas treatment, in particular to a heavy-duty vehicle DPM (Diesel Particulate Matter, commonly known as hydrocarbon injection system) exhaust after-treatment device and a heavy-duty vehicle. Background technique [0002] In order to avoid increasingly serious ecological and climate disasters, reduce greenhouse gas emissions, control environmental pollution, and develop a low-carbon economy, it has become a global consensus. At the same time, with the increasingly stringent emission regulations, the exhaust gas of heavy-duty vehicles must be treated more strictly before it can be discharged. [0003] The existing heavy-duty vehicle exhaust gas treatment is through DOC and SCR. DOC is an oxidation catalyst that can catalyze and oxidize HC, CO, and NO gas emissions in the exhaust gas to generate NO 2 and CO 2 . SCR is selective catalytic reduction, and the reducing agent used in the SCR system...
