Description
Technical field
The present invention relates to a kind of devices of car assisted engine work, are specifically a kind of automobile of assisted engine work
Exhaust pipe heat retracting device.
Background technology
During automobile engine cold start, the clean-burning work of fuel oil is extremely difficult in the engine temperature short time
Make temperature, engine noise is big when this causes cold start, and fuel oil can not fully burn, and generally requires the hot vehicle for carrying out a few minutes
After could go up road, this phenomenon is particularly evident in winter, not only makes troubles to driving, and main is that fuel oil can be caused to damage
Consumption, and the tail gas of its discharge will severely exceed.
And waste pipe, the exhaust temperature of discharge are 90 degrees Celsius or more reachable once starting in engine, but
It is all exhausted directly in air, is not effectively utilized.
The content of the invention
In view of the above-mentioned problems, the present invention devises a kind of automobile exhaust pipe heat reclaim unit of assisted engine work,
Tail gas heat quantity in exhaust pipe can be recycled the cold start work with assisted engine by it, can effectively be shortened and be started
The cold vehicle working time of machine, reduce the exceeded tail gas of cold start discharge, and can reduce to a certain extent oil consumption and for driving
It is convenient to provide.
To achieve the above object, the present invention uses following technical scheme：
A kind of automobile exhaust pipe heat reclaim unit of assisted engine work, it is characterised in that：Including automobile engine and row
Tracheae；A heat exchanger is provided on the outside of the exhaust pipe, water circulation pipe and circulation of tail gas passage are equipped in heat exchanger；Institute
The inlet and outlet for stating water circulation pipe are connected respectively by water inlet pipe and outlet pipe with chilled(cooling) water return (CWR) in engine, water
Water in circulation line drives jointly by the water pump of cooling water in engine；The import and exhaust of the circulation of tail gas passage
Pipe front end connects, and the outlet of circulation of tail gas passage is connected with exhaust pipe rear end；Control valve is provided in the middle part of the exhaust pipe, is controlled
The rotation of valve processed can close exhaust pipe or close the outlet of circulation of tail gas passage, and exhaust pipe is closed in engine cold start,
The outlet of circulation of tail gas passage is closed after engine temperature reaches normal working temperature.
Further, cooling-water temperature sensor is provided in chilled(cooling) water return (CWR) in above-mentioned engine, cooling-water temperature sensor believes water temperature
Number real-time delivery and is controlled by car running computer the action of control valve to the car running computer of automobile according to the water temperature signal of acquisition.
Further, the normal working temperature scope of above-mentioned engine is 85 ~ 105 °.
Tail gas the present invention is based on automobile exhaust pipe starts in engine one and reaches the principle of 90 ° or more high temperature and set
Meter.
When engine cold-start temperature is not reaching to normal working temperature, the control valve in the middle part of exhaust pipe cuts exhaust pipe
The only outlet of circulation of tail gas passage conducting, the tail gas of high temperature can only be discharged through the circulation of tail gas passage in heat exchanger.
In the process, the high-temperature tail gas in circulation of tail gas passage will carry out heat exchange with the water in water circulation pipe, so that water temperature
Quick rise, the water after temperature rise, which is flowed to through outlet pipe in the cooling water system of engine, makes cooling water heat up, quickly to carry
The temperature of engine is risen, and then realizes that engine reaches normal working temperature in a short period of time.And when engine arrival is set
When determining operating temperature, control valve rotation turns on exhaust pipe and closes circulation of tail gas passage, and tail gas can be with normal discharge, and cuts
The heat exchange of docking gas and heat exchanger stops heat recovery, to prevent that cooling water overheats in engine.
Description of the drawings
The planar structure schematic diagram of Fig. 1, the present invention；
Fig. 2, circulation of tail gas passage port closing after planar structure schematic diagram.
Specific embodiment
As shown in Figure 1, a kind of automobile exhaust pipe heat reclaim unit of assisted engine work, including 1 of automobile engine
With exhaust pipe 2.
2 outside of exhaust pipe is provided with a heat exchanger 3.Water circulation pipe 31 is equipped in heat exchanger 3 and tail gas follows
Ring passage 32.
The water inlet 311 and water outlet 312 of the water circulation pipe 31 are respectively by water inlet pipe 4 and outlet pipe 5 with starting
Chilled(cooling) water return (CWR) 11 connects in machine 1, and the water in water circulation pipe 31 drives jointly by the water pump 12 of cooling water in engine 1
It is dynamic.
The import 321 of the circulation of tail gas passage 32 is connected with 2 front end of exhaust pipe, the outlet 322 of circulation of tail gas passage 32
It is connected with 2 rear end of exhaust pipe.
The middle part of the exhaust pipe 2 is provided with control valve 6, and when 61 cold start of engine of control valve closes exhaust pipe 2,
1 temperature of engine reaches the outlet 322 of closing circulation of tail gas passage 32 after normal working temperature.The normal work of the engine 1
Make temperature range as 85 ~ 105 °.
Tail gas the present invention is based on automobile exhaust pipe 2 starts in engine 1 one and reaches the principle of 90 ° or more high temperature and set
Meter.
When 1 cooling start temperature of engine is not reaching to normal working temperature, the control valve 6 at 2 middle part of exhaust pipe makes exhaust
Pipe 2 ends and the outlet 322 of circulation of tail gas passage 32 turns on, and structure is as shown in Figure 1, the tail gas of high temperature can only be handed over through heat at this time
Circulation of tail gas passage 32 in parallel operation 3 is discharged.In the process, the high-temperature tail gas in circulation of tail gas passage 32 will be followed with water
Water in endless tube road 31 carries out heat exchange, so that water temperature quickly raises, the water after temperature rise flows to engine through outlet pipe 5
In 1 cooling water system cooling water is made to heat up, with the temperature of fast lifting engine 1, and then realize engine 1 when very short
It is interior to reach normal working temperature.
And when engine 1 reaches setting operating temperature, the rotation of control valve 6 makes exhaust pipe 2 turn on and lead to circulation of tail gas
Road 32 is closed, structure as shown in Fig. 2, tail gas can be with normal discharge at this time, and cuts off the heat exchange of tail gas and heat exchanger 3,
Stop heat recovery, to prevent that cooling water overheats in engine 1.
Tail gas heat quantity in exhaust pipe 2 can be carried out recycling profit by the automobile exhaust pipe heat reclaim unit of more than structure
Work to the cold start of assisted engine 1, can effectively shorten cold vehicle working time of engine 1, reduce cold start because
Exceeded exhaust emissions caused by fuel oil burning is insufficient, and oil consumption can be reduced to a certain extent and provided conveniently for driving.
Here, accurately to detect the operating temperature of engine 1 and control the work of control valve 6, the engine 1 in real time
Chilled(cooling) water return (CWR) 11 in be provided with cooling-water temperature sensor 7, cooling-water temperature sensor 7 is by water temperature signal real-time delivery to the driving electricity of automobile
Brain 8, and the work of control valve 6 is controlled by car running computer 8 according to the water temperature signal of acquisition.
The above is only the better embodiment of the present invention, not makees limitation in any form to invention, it is every according to
According to the technical principle of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, the present invention is still fallen within
In the range of technical solution.
