Abstract
The utility model discloses an exhaust gas recirculation cooling device with a more reasonable structure. The scheme of the exhaust gas recirculation cooling device includes that a gas inlet pipe and a gas outlet pipe are respectively connected to a gas side of an EGR (exhaust gas recirculation) cooler, a water outlet pipe and a water inlet pipe are respectively connected to a water side of the EGR cooler, and a fixing support is mounted at an outer joint of the EGR cooler with the gas outlet pipe. The gas inlet pipe of the EGR cooler is connected with an exhaust pipe of an engine, exhaust gas is led into the EGR cooler, and the gas outlet pipe of the EGR cooler is connected to a gas inlet pipe of the engine. A part of cooling water in an oil cooler of the engine is led into the water inlet pipe of the cooler, and the water outlet pipe of the cooler is connected back onto a warm air water pipe of an integral vehicle. The exhaust gas recirculation cooling device meets the requirement of spatial size by means of design that movable joints are mounted in the middles of pipelines of each of the gas inlet pipe, the gas outlet pipe, the water inlet pipe and the water outlet pipe, and a flexible pipe section is further mounted in the middle of each of the pipelines of each of the gas inlet pipe and the gas outlet pipe. Accordingly, the four pipes can be connected with all corresponding accessories of the engine extremely flexibly, and an external space of the engine is effectively reduced.
Description
Technical field
The utility model belongs to internal combustion engine component, is specifically related to a kind of exhaust gas recirculation cooling device.
Background technique
Along with going from bad to worse of grobal environment, impel countries in the world man also strict day by day to the emission request of motor.Well-known engine exhaust recirculation (hereinafter to be referred as EGR) technology can effectively reduce the noxious emission of NOx, so the improvement of cooling system for recycled exhaust gas technology receives the concern of each manufacturer.The technological difficulties of cooling system for recycled exhaust gas are that cooling system for recycled exhaust gas not only will improve density of the induced air by reducing intake temperature, under the prerequisite that satisfies the engine emission requirement, also will satisfy the requirement in spaces such as system's assembling, size cooperation.The utility model proposes a kind of motor on the basis of satisfying state IV emission standard, taking into account system change simultaneously is less, satisfies the exhaust gas recirculation cooling device that bulk requires.
Summary of the invention
The purpose of this utility model provides more reasonably cooling system for recycled exhaust gas device of a kind of structure.
Below in conjunction with accompanying drawing principle of the present utility model and structure are described.Exhaust gas recirculation cooling device comprises: cooler for recycled exhaust gas, suction tude, steam outlet pipe, outlet pipe, intake pipe, fixed support and flange-interface.The gas side of cooler for recycled exhaust gas is connected to suction tude and steam outlet pipe respectively, and the water side of cooler for recycled exhaust gas is connected to outlet pipe and intake pipe respectively.The outside jointing of cooler for recycled exhaust gas and steam outlet pipe is equipped with fixed support.In the middle of each pipeline of described suction tude, steam outlet pipe, intake pipe and outlet pipe Active Interface is housed, still is connected to one section flexible tube section in the middle of each pipeline of suction tude and steam outlet pipe.Each pipeline end of described suction tude and steam outlet pipe is welded with flange-interface.Structural principle of the present utility model is, the gas side that a part of waste gas of being drawn by engine exhaust pipe enters cooler, and cooler is a heat exchanger, and the water side is connected with condensed water, and the waste gas of high heat enters motor once more after the cooler cooling.By reducing the temperature that EGR enters intake duct, improve density of the induced air, reach the purpose that lowers the NOx noxious emission.The design that the utility model satisfies the bulk requirement is in the middle of each pipeline of suction tude, steam outlet pipe, intake pipe and outlet pipe Active Interface to be housed, and still to be connected to one section flexible tube section in the middle of each pipeline of suction tude and steam outlet pipe.The purpose of this design makes the quite flexible connection of four pipeline sections and corresponding each annex of motor exactly, has effectively reduced the external engine space.Be the design of each parts and be arranged in when satisfying engine emission and require, also satisfy the car load arrangement requirement.
Characteristics of the present utility model and beneficial effect are that structural design is comparatively simple, increases cooling system for recycled exhaust gas on the motor basis that meets state III emission standard originally, and other parts are constant, with low cost, make it satisfy state IV emission standard, and can satisfy the spatial design requirement.And can effectively reduce the NOx of motor and prolong the product life cycle.
