Description
技术领域 technical field
本实用新型涉及内燃机排气系统中的增压器排气接口装置。The utility model relates to a turbocharger exhaust interface device in an internal combustion engine exhaust system.
背景技术 Background technique
现有内燃机排气系统中增压气的排气接口装置的法兰与进气管之间的连接方式是将进气管插入法兰的进气孔中一段距离后，将两者焊接。现有的这种法兰与进气管之间的连接方式存在的不足是：气流从法兰的进气口进入时，会直接冲击到进气管的端部或焊缝处，导致此处气流不均匀流动，使气流的流动受到影响，并影响背压。The connection mode between the flange and the intake pipe of the exhaust interface device of the supercharged gas in the existing internal combustion engine exhaust system is to insert the intake pipe into the intake hole of the flange for a certain distance, and then weld the two. The disadvantage of the existing connection between the flange and the air intake pipe is that when the air flow enters from the air inlet of the flange, it will directly impact the end of the air intake pipe or the welding seam, causing the air flow here to be uneven. Uniform flow, so that the flow of the airflow is affected and affects the back pressure.
实用新型内容Utility model content
本实用新型的目的在于提供一种内燃机增压器排气接口装置，由增压器出口向该排气接口装置排出的气流流动顺畅，排气背压小。The purpose of the utility model is to provide a supercharger exhaust interface device of an internal combustion engine, the air flow discharged from the outlet of the supercharger to the exhaust interface device flows smoothly, and the exhaust back pressure is small.
为实现上述目的，本实用新型采用以下方案：内燃机增压器排气接口装置，它由法兰与进气管相接构成，法兰的进气孔与进气管的内孔光滑相接。In order to achieve the above object, the utility model adopts the following scheme: an internal-combustion engine supercharger exhaust interface device, which is formed by connecting a flange with an intake pipe, and the intake hole of the flange is smoothly connected with the inner hole of the intake pipe.
由上述方案可见，由于法兰的进气孔与进气管的内孔光滑相接，得以实现进入法兰进气孔的气流在两者连接部位流畅的流动，从而相应的减少排气背压。It can be seen from the above scheme that since the inlet hole of the flange is smoothly connected with the inner hole of the inlet pipe, the airflow entering the inlet hole of the flange can flow smoothly at the joint between the two, thereby reducing the exhaust back pressure accordingly.
本实用新型结构合理，它可使气流从增压器出口流出后均匀的流动，减少催化器进气法兰与进气端锥之间的气流扰动。The utility model has a reasonable structure, which can make the airflow flow uniformly after flowing out from the supercharger outlet, and reduce the airflow disturbance between the inlet flange of the catalytic converter and the inlet end cone.
