Abstract
The utility model relates to an exhaust manifold device of an engine, comprising an air inlet flange disc, an exhaust-pipe upper shell, an exhaust-pipe lower shell, a manifold, an air outlet flange disc and an oxygen sensor seat, wherein four air passage ports are respectively arranged on the air inlet flange disc, the exhaust-pipe upper shell and the exhaust-pipe lower shell are welded to form four air inlets and one air outlets, the four air inlets are in butt joint with four air passages of the air inlet flange disc, and the air outlet is connected with the air inlet end of the manifold on which the oxygen sensor seat and the air outlet flange disc are welded. The exhaust manifold device has the advantages of compact structure, reasonable design, low cost, safety and reliability, convenient operation, use, installation and disassembly, light weight, small heat capacity and less heat absorption, a catalyst can be rapidly burnt so that the contents of discharged pollutants are reduced, thereby the exhaust manifold device meets the requirement of environmental protection.
Description
Technical field
The utility model relates to a kind of automobile with small output volumn Engine Exhaust manifold Device.
Background technique
At present, enmgine exhaust mostly is foundry goods, and mould complexity, wall thickness, weight is big, thermal capacity is big, and it is many to absorb heat.Car body is when low-temperature cool starting, and the heat loss of engine cylinder-body combustion gas is bigger.Three-way catalyst is difficult to reach the temperature of catalytic reaction in preceding 40 seconds of image data, and causing discharging pollutants exceeds standard.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, Engine Exhaust manifold Device with low cost, safe and reliable, as to reduce complete machine weight.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise air inlet flange disks, outlet pipe upper shell, outlet pipe lower shell body, gather pipe, the flange plate of giving vent to anger, lambda sensor seat, establish four gas ports on the air inlet flange disks respectively, outlet pipe upper shell and outlet pipe lower shell body are welded to form 4 suction ports and an air outlet, four air flues of 4 suction ports and air inlet flange disks connect, the air outlet with gather the pipe inlet end join, the lambda sensor seat and the flange plate of giving vent to anger are welded on and gather on the pipe.
The utility model has the advantages that:
Compact structure, reasonable in design, with low cost, safe and reliable, easy for operation, easy installation and removal, weight is little, thermal capacity is little, and it is few to absorb heat, makes to satisfy environmental requirement by catalyzer ignition and reduce the content that discharges pollutants fast.
