Problems solved by technology

In places where it is difficult to hold the bolt with a tool, a standoff attached to the bolt head must be installed to tighten the nut, causing inconvenience to the operator
[0005] Furthermore, the problem with this conventional method is that once the EGR pipe has been attached to the intake manifold by bolts and nuts, it is difficult to disassemble and reassemble

Abstract

Disclosed herein is an apparatus for connecting between an intake manifold and an EGR pipe. The apparatus includes an intake manifold connector, connected to an intake side of the intake manifold in a ring shape with a prescribed thickness and having a plurality of holes passing through external perimeter and internal perimeter of the intake manifold connector. The EGR pipe is inserted into the intake manifold connector and connected to the intake side of the intake manifold to guide waste gas to the intake manifold. A clip is connected to the intake manifold connector through elastic attrition connection and passes through the plurality of holes to alternately contact the external perimeter and the internal perimeter of the intake manifold connector, so as to prevent the EGR pipe from separating from the intake manifold connector.

Description

technical field [0001] In general, the present invention relates to a device for connecting an intake manifold with an EGR (Exhaust Gas Recirculation) pipe; and more particularly, the present invention relates to such a device for connecting an intake manifold with an EGR pipe , the device is configured to connect the intake manifold and the EGR pipe using steel clips, thereby enabling easy disassembly and reassembly without space restriction. Background technique [0002] Recently, environmental pollution caused by automobile exhaust gas has become a problem. Therefore, as regulations related to exhaust gas become increasingly stricter, in order to reduce nitrogen oxides NO X To reduce emissions, an Exhaust Gas Recirculation (EGR) system is installed in the vehicle, and the EGR system returns a part of the exhaust gas generated after combustion to the combustion chamber via the intake manifold. [0003] The EGR system includes an EGR pipe connected to the intake manifold....
