Summary device for reduction of exhaust gas which is filled in a part of the exhaust end of the tube by which the other part of the end to be connected to an engine mounted on a estruturThe principal of the heavy equipment device for reduction of exhaust gas for heavy equipment.It can meet the standards of exhaust gases from diesel engines through the provision of a device for selective catalytic reduction (SCR), in addition to a diesel particulate filter (DPF).And to minimize the influence of vibration due to the mechanism of conduction through the assembly of diesel particulate filter (DPF) and the device of selective catalytic reduction (CBS) in a structure.Hood.The apparatus for the reduction of an exhaust gas includes a structure of top mounted on a side of the main frame.It is adjacent to the engine for reducing an influence due to vibration of the engine, and a diesel particulate filter (DPF) having an end portion which communicates with the other part of the edge.The exhaust manifold, and is mounted on a part of the upper end of the structure of the canopy, fitted with diesel oxidation catalyst (DOC) in the same.And the capture of particulate matter; a tube of mixture, with a part of the end that communicates with the other part of the tip of the diesel particulate filter.A side that communicates with an injection device injecting a reducing agent; and a device for selective catalytic reduction (SCR) mounted in a part of the upper end of the estrutuRa of the hood to communicate with the other part of the tube end of the mixture to accelerate the reaction of reduction between the reducing agent injected and nitrogen oxides (NOx) in the exhaust gas.
