Description

Engine EGR exhaust gas pipe with water channel
Technical Field
The utility model relates to an automobile parts field, concretely relates to take engine EGR exhaust gas pipe of water course.
Background
With the improvement and the upgrade of emission level, an external EGR (exhaust gas recirculation) system becomes a necessary technical route of a small-sized vehicle engine, and the system needs to arrange an EGR cooler, an EGR valve, pipelines (a water pipe and an air pipe), a bracket and other parts outside an engine cylinder cover to ensure that exhaust gas is led into an air inlet side from an exhaust side, and ensure the cooling water circulation of the EGR cooler and the EGR valve. In the existing EGR system, each pipeline is independent, an EGR valve needs to be fixed through a support, the number of parts is large, and the arrangement structure is complex.
Disclosure of Invention
The utility model aims at overcoming the not enough of above-mentioned background art, provide an engine EGR exhaust gas pipe of taking the water course.
In order to realize above purpose, the utility model provides a pair of take engine EGR exhaust gas pipe of water course, including the body, be located the EGR valve connecting portion of body one end and be located the engine cylinder lid connecting portion of the body other end, be equipped with water channel and gas passage in the body, be equipped with water channel export, gas passage export and EGR valve connecting hole on the terminal surface of EGR valve connecting portion, be equipped with water channel entry, gas passage entry and engine cylinder lid connecting hole on the terminal surface of engine cylinder lid connecting portion.
In the scheme, the pipe body, the EGR valve connecting part and the engine cylinder cover connecting part are all aluminum alloy casting parts.
The utility model provides a beneficial effect that technical scheme brought is:
the utility model discloses intensity is high, and the support that can replace realizes having reduced spare part quantity to the support of EGR valve, and the cost is reduced can also play certain cooling action to the waste gas through EGR exhaust gas pipe.
Drawings
Fig. 1.1 is a schematic structural diagram of the present invention;
fig. 1.2 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the cross-sectional structure of the tube body of the present invention;
fig. 3 is a schematic structural diagram of the utility model after installation.
In the figure: the EGR valve comprises a pipe body 1, a water passage 1a, an air passage 1b, an EGR valve connecting part 2, a water passage outlet 2a, an air passage outlet 2b, an EGR valve connecting hole 2c, an engine cylinder cover connecting part 3, a water passage inlet 3a, an air passage inlet 3b, an engine cylinder cover connecting hole 3c, an engine 4 and an EGR valve 5.
Detailed Description
The invention is described in further detail below with reference to the figures and examples.
As shown in fig. 1, the engine EGR exhaust pipe with water channel includes a pipe body 1, an EGR valve connecting portion 2 located at one end of the pipe body 1, and an engine cylinder head connecting portion 3 located at the other end of the pipe body 1, a water passage 1a and an air passage 1b are provided in the pipe body 1, a water passage outlet 2a, an air passage outlet 2b, and an EGR valve connecting hole 2c are provided on an end surface of the EGR valve connecting portion 2, and a water passage inlet 3a, an air passage inlet 3b, and an engine cylinder head connecting hole 3c are provided on an end surface of the engine cylinder head connecting portion 3.
The pipe body 1, the EGR valve connecting part 2 and the engine cylinder cover connecting part 3 are all aluminum alloy castings.
The utility model discloses a theory of operation does:
the EGR valve 5 is connected with a cylinder cover of the engine 4 through the utility model, and cooling water flows through the water channel 1a and then is guided back to the water pump pipeline through the water return pipe to participate in the size circulation; exhaust gas generated in the cylinder of the engine 4 enters the EGR valve 5 through the gas passage 1b and then participates in recirculation of exhaust gas through the pipe.
Other parts not described in detail are known in the art.
