Abstract
The utility model discloses a kind of water fetching device of diesel exhaust recycle cooler, its structure is: the cooling water of machine oil cooler being discharged introduces cooler for recycled exhaust gas, and machine oil cooler water outlet is communicated with EGR intake pipe by water intaking joint.The two ends of water intaking joint are thread section, and wherein threaded one end section is connected with machine oil cooler water outlet; The other end is connected with intake pipe, and intake pipe is connected to the water intake of cooler for recycled exhaust gas.This device covers increase water outlet in traditional machine oil cooler, and designs the particular location of this water outlet and corresponding dimensional parameters.The cooling water of machine oil cooler being discharged continues cooled exhaust air, makes the cooling water after cooling machine oil obtain secondary and utilizes, can meet again the requirement of cooler for recycled exhaust gas chilling temperature simultaneously.This apparatus structure is simple, easily layout, machine oil cooler water intaking position rationally, because this position is close to cooler for recycled exhaust gas, shorten length and the good cooling results of connecting pipeline.
Description
Technical field
The utility model belongs to engine components technical field, is specifically related to the cooler water fetching device in a kind of gas recirculation system.
Background technique
At present along with the attention of Environmental pollution, the rule more also increasingly stringent of motor vehicle exhaust emission method, in order to reduce the discharge of harmful matter in vehicle exhaust, most of motor all have employed EGR (EGR) technology.The principle of EGR is by after a part of exhaust cooling, introduces suction tude and mixes with fresh air, and then enter cylinder combustion, reaches reduce maximum combustion temperature suppression NO in cylinder with this
xthe object that (nitrogen oxidize particulate matter) generates.Wherein the effect of cooler for recycled exhaust gas is, reduces delivery temperature through EGR valve to the waste gas of introducing portion by cooling water.Due to the impact of arranging by diesel engine space outerpace, the layout of different model diesel engine EGR system is different, and its water intaking structure is also different.Large multi-model is fetched water in body cylinder sleeve water cavity, and the defect of this method is that body producting process difficulty is comparatively large, and cost is also higher; Meanwhile, water intaking path is far away, and pipeline more complicated, makes efficiency lower.The water fetching device that the utility model proposes, can meet the cooling water supply of multi-model.
Summary of the invention
The purpose of this utility model is, provides a kind of water fetching device of diesel exhaust recycle cooler.
For realizing this object the technical solution adopted in the utility model be: the cooling water of machine oil cooler being discharged is as the cooling water of cooler for recycled exhaust gas, and machine oil cooler water outlet is communicated with EGR intake pipe by water intaking joint.
Innovative point of the present utility model covers in traditional machine oil cooler to increase water outlet (hole), and design the particular location of this water outlet and corresponding dimensional parameters.Specific practice is that the cooling water of machine oil cooler being discharged introduces cooler for recycled exhaust gas by water intaking joint, intake pipe, makes the cooling water after cooling machine oil obtain secondary and utilizes, can meet again the requirement of cooler for recycled exhaust gas chilling temperature simultaneously.
Feature of the present utility model and beneficial effect are that structure is simple, easily layout, machine oil cooler water intaking position rationally, because this position is close to cooler for recycled exhaust gas, shorten length and the good cooling results of connecting pipeline.
Accompanying drawing explanation
Fig. 1 is that schematic diagram cuts open in the office of the utility model Principles and methods.
Fig. 2 is the dimensioned drawing of machine oil cooler intake plan-position.
Fig. 3 is the dimensioned drawing of machine oil cooler intake endface position.
Embodiment
Structure of the present utility model to be further described by specific embodiment referring to accompanying drawing.
The water fetching device of diesel exhaust recycle cooler, comprises machine oil cooler, cooler for recycled exhaust gas, intake pipe and intake pipe joint etc.Its structure is: the cooling water of machine oil cooler 1 being discharged is as the cooling water of cooler for recycled exhaust gas 2, and machine oil cooler water outlet is communicated with (as Fig. 1) with EGR intake pipe 3 by water intaking joint 4.The two ends of water intaking joint are thread section, and wherein threaded one end section is connected with machine oil cooler water outlet; The other end is connected with intake pipe, and intake pipe is connected to the water intake of cooler for recycled exhaust gas.
To the design of machine oil cooler water outlet position be: machine oil cooler water outlet height is apart from machine oil cooler distance H1=30mm (as Fig. 3); With the center of machine oil cooler upper corners bolt mounting holes 1-1 for reference point, EGR intake pipe water outlet horizontal position L1=136mm; Vertical position H2=54mm (as Fig. 2); The outer diameter D 1=30mm of water outlet; Internal diameter D2=17mm.
Engine exhaust pipe is connected with cooler for recycled exhaust gas suction tude by flange, thus a part of waste gas is introduced cooler for recycled exhaust gas, has dress EGR valve between cooler for recycled exhaust gas and air inlet tube simultaneously.The steam outlet pipe of cooler for recycled exhaust gas is connected with engine air inlet tube by flange, will send into cylinder and carry out compression ignite after the cooled waste gas of cooler for recycled exhaust gas mixes with fresh air.
