Abstract

The present invention relates to a reduction system for particulate materials in exhaust gas, which is connected to a tailpipe of an engine that burns a hydrocarbon-based fuel supplied from a fuel storage tank, and collects and removes particulate materials within the exhaust gas, may include a plasma reactor having a gas inlet and an outlet, and a DPF (diesel particulate filter) trap having a filter. The tailpipe of the engine may communicate with the gas inlet of the plasma reactor, and the outlet of the plasma reactor may communicate with the DPF trap. The exhaust gas exhausted from the engine may be transferred to the DPF trap after being heated while passing through the plasma reactor.

Description

technical field [0001] The present invention relates to a vehicle exhaust gas post-treatment system, and more particularly to a plasma reactor and a reduction system for particulate matter in exhaust gas, wherein the reactor and the system can pass through diesel particulate filter (diesel particulate filter) , DPF) before the filter of the trap heats the exhaust gas to oxidize and effectively remove the particulate matter, thereby being used to remove the particulate matter in the exhaust gas generated by the engine. Background technique [0002] Particulate matter (PM) in vehicle exhaust is mainly emitted by diesel engines, which generally control output power by mixing air and fuel in a certain proportion. When a large instantaneous power is required, a diesel engine needs to provide and burn more fuel than a certain amount of air. At this time, due to the lack of air, the fuel cannot be fully burned, and a large amount of vehicle emissions will be generated. Moreover, ...
