Description

Water-cooled injection device for DPF regeneration

Technical Field

The utility model relates to a DPF regeneration technical field, concretely relates to water-cooled is used for DPF regenerated injection apparatus.

Background

In order to meet increasingly stringent emission regulations, current internal combustion engines, particularly diesel internal combustion engines, are required to be equipped with exhaust gas aftertreatment systems, including diesel particulate traps (DPFs). Such traps accumulate soot during engine operation and thus cause an increase in engine exhaust back pressure, with consequent deterioration in the economy and dynamics of diesel internal combustion engines, so that the trapped soot must be burned off in a timely manner to effect regeneration of the diesel particulate trap. Therefore, atomized diesel oil needs to be injected into the exhaust pipe of the diesel engine at regular time and quantity, atomized diesel oil droplets and exhaust gas in the exhaust pipe are mixed to generate violent oxidation reaction in an oxidation catalyst (DOC), and huge heat generated by the oxidation reaction comes into the DPF along with the exhaust gas to ignite carbon black particles, so that the regeneration of the DPF is realized.

The injection device is an important part in DPF regeneration technology, and due to the severe use environment, the injection devices used in the DPF regeneration technology on the market at present are complex in structure and high in manufacturing difficulty, so that the cost is high.

The above problems are problems that the art needs to solve.
