Abstract

The invention provides an exhaust system and a power system. The exhaust system comprises a first pipeline and a second pipeline. An air inlet of the first pipeline is used for leading in waste gas. One end of the second pipeline communicates with the first pipeline, and the other end of the second pipeline is used for leading in air. When waste gas flows through a catalytic unit, the waste gas iscatalyzed by the catalytic unit to generate a redox reaction, and the rest of gas flows to a particle collecting unit continuously. The particle collecting unit collects particles in the rest of gas,and an oxidation reaction is conducted on the particles and the air led in the second pipeline. Due to the fact that a large amount of heat is released through the oxidation reaction, the temperaturein the particle collecting unit is increased, the oxidation reaction can be conducted on the particles and the air continuously after the temperature in the particle collecting unit is increased, initiative regeneration of energy is achieved, and in addition, the phenomenon that the particles are accumulated in the particle collecting unit for a long term, and consequently the pipelines are blocked is avoided.

Description

technical field [0001] The invention relates to the field of automobile manufacturing equipment, in particular to an exhaust system and a power system. Background technique [0002] Automobile exhaust system refers to the system that collects and discharges exhaust gas, mainly to discharge the exhaust gas emitted by the engine, and at the same time reduce the pollution of the exhaust gas and reduce the noise. [0003] Existing automotive exhaust systems usually include an exhaust system, a catalytic converter, and a particulate filter. Due to factors such as the layout of the vehicle chassis, the exhaust system is relatively long, and the distance between the exhaust manifold of the automotive engine and the particulate filter Longer, in the environment of low speed, small load and low temperature of the car, the internal temperature of the particle filter will be low, for example, it cannot exceed 450°C, and regeneration cannot be achieved, so long-term accumulated particle...
