Abstract
The utility model relates to a water outlet switching device of an engine. The body is fixedly connected with an adapter, the body and the adapter are provided with an exhaust gas recirculation system exhaust gas channel and a cooling water channel inside, one side of the body is provided with an exhaust gas recirculation system valve body mounting end surface, and the right side of the adapter is provided with a connecting end surface. One end of the exhaust gas recirculation system exhaust gas channel is provided with an exhaust gas recirculation system circulation exhaust gas inlet, the other end is provided with an exhaust gas recirculation system circulation exhaust gas outlet; one end of the cooling water channel is provided with a cooling water inlet, the other end is provided with a cooling water path outlet; and a plug is equipped on the exhaust gas recirculation system circulation exhaust gas outlet of the exhaust gas recirculation system exhaust gas channel. The water outlet switching device is compact in structure and reasonable in design, the exhaust gas channel of the exhaust gas recirculation system and the cooling liquid outlet switching channel are integrated, and a mounting position is provided for the exhaust gas recirculation system, thus effectively utilizing space, reducing the waste of raw material and lowering the manufacture cost.
Description
Technical field
The utility model relates to a kind of motor water outlet switching device, especially a kind of motor water outlet switching device that can cool off the waste gas in the gas recirculation system.
Background technique
At present,, generally adopt gas recirculation system to reduce the content of nitrogen oxide in the tail gas on the market, realize motor water outlet signaling transfer point because Abgasgesetz to the restriction of amount of nitrogen oxides in the exhaust emissions, needs to reduce the nitrogen oxide in the exhaust emissions.But for small displacement engine, because the designing requirement compact structure of itself, and the arrangement space in the car load cabin is also very limited, needs effectively to utilize the space like this in design process, is satisfying under the prerequisite of function, utilizes minimum space.The passage of gas covers at engine cylinder in the existing gas recirculation system, outlet is two independent structures with the water outlet adapter, the two is at a distance of nearer, and the gas recirculation system arrangement space requires bigger, if guarantee the arrangement space of gas recirculation system, will make the structure of motor compact inadequately, be unfavorable for that car load carries; In addition, the exhaust gas temperature in the gas recirculation system is higher, if the insufficient valve body and the plastic air intake manifold that probably can damage gas recirculation system of cooling causes thrashing.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and has effectively utilized the space, has reduced the waste of raw material, reduces the motor water outlet switching device of manufacture cost.
In order to achieve the above object, the technical solution adopted in the utility model is: be connected with adapter on body, have gas recirculation system cycle gas passage and cooling water passage in body and the adapter, body one side is provided with the gas recirculation system valve body end face is installed, the adapter right side is provided with the connection end face, gas recirculation system cycle gas passage one end is provided with gas recirculation system cycle gas inlet, the other end is provided with the outlet of gas recirculation system cycle gas, cooling water passage one end is provided with the cooling water water inlet, the other end is provided with the cooling water channel outlet, and screw plug is loaded on the gas recirculation system cycle gas outlet port of gas recirculation system cycle gas passage.
The utility model has the advantages that:
Compact structure, reasonable in design, the exhaust steam passage and the cooling liquid water outlet Switching-through channel of gas recirculation system is integrated, and, effectively utilized the space for the gas recirculation system valve body provides holding position, and reduced the waste of raw material, reduce manufacture cost; Effectively reduce in the gas recirculation system and circulate, avoid damaging gas recirculation system valve body and plastic air intake manifold with the temperature of waste gas; Integrated a plurality of component function is also installed for the gas recirculation system valve body position is provided, and has made things convenient for the gas recirculation system outlet to arrange and the car load layout.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 4 as can be known, the utility model is connected with adapter 6 on body 7, have gas recirculation system cycle gas passage 3 and cooling water passage 11 in body 7 and the adapter 6, body 7 one sides are provided with the gas recirculation system valve body end face 1 are installed, adapter 6 right sides are provided with and connect end face 5, gas recirculation system cycle gas passage 3 one ends are provided with gas recirculation system cycle gas inlet 4, the other end is provided with gas recirculation system cycle gas outlet 10, cooling water passage 11 1 ends are provided with cooling water water inlet 8, the other end is provided with cooling water channel outlet 2, and the gas recirculation system cycle gas that screw plug 9 is loaded on gas recirculation system cycle gas passage 3 exports 10 places.
The utility model is installed end face 1 place at the utility model gas recirculation system valve body and is connected the gas recirculation system valve body, connects end face 5 places and connects cylinder cap.When engine operation, the waste gas of gas recirculation system circulation usefulness enters adapter 6 by its inner passage by cylinder cap, enter the gas recirculation system valve body of adapter 6 front ends then by the gas recirculation system cycle gas passage 3 in adapter 6 and the body 7, gas recirculation system cycle gas passage 3 adjacent cooling water passages 11, the effective waste gas in the cooled exhaust air recirculating system, the device front-end face is provided with the gas recirculation system valve body end face 1 is installed, for the installation of gas recirculation system valve body provides the position.Screw plug 9 is used to seal cell ends and needs gluing before preventing gas leakage, installing.
