Description
Technical Field
The present invention relates to an air intake duct for a vehicle and an air intake system for a vehicle including the same, and more particularly, to an air intake duct for a vehicle and an air intake system for a vehicle including the same, which can reduce an intake temperature under an idle condition and a traveling condition, and can improve a waterproof structure.
Background
A typical example of an internal combustion engine of a vehicle is generally configured in four cycles, and the engine is driven by sucking external air by generating negative pressure by repeated actions of piston lifting in a cylinder, injecting fuel into a combustion chamber where the air is sucked, preparing appropriate mixed gas, and igniting the mixed gas. In this case, the open intake valve is opened once when the piston descends for the intake stroke, and intake air flows in through the intake device.
Such an intake device includes: the air cleaner includes an intake manifold connected to an intake port of the engine, a surge tank communicated with the intake manifold, an intake duct communicated with the surge tank, an air filter connected to the intake duct, and an intake duct introducing outside air to the air filter. A throttle body used for adjusting the air suction amount is arranged between the pressure adjusting chamber and the air inlet pipeline.
The intake device is provided with an intake duct for introducing external air into the engine, and the intake duct guides the external air to an air cleaner and plays a role of controlling noise and vibration generated by the external air flowing into the engine.
In order to drive the engine to generate power, a certain amount of air is required, and air required for combustion is taken into an intake duct inside the vehicle from outside the vehicle and is supplied to the engine. More specifically, air outside the vehicle (i.e., outside air) is drawn into the intake duct by a negative pressure generated by driving the engine, and then supplied to the intake manifold of the engine through the air filter and the air hose.
However, the conventional intake duct is generally mounted on a trim (trim) in the front of the vehicle, and a separate device for taking in outside air is not provided. Therefore, some of the outside air sucked through the radiator grill flows into the intake duct through the latch hole (latchhole) or the like, but it is difficult to suck sufficient outside air. Thus, air inside the engine room heated by the radiator or the engine is drawn into the intake duct by the negative pressure of the engine.
The intake air temperature refers to the temperature of air supplied to the engine after passing through the intake system (intake duct + air filter + air hose) of the vehicle. When the intake air temperature is lowered by 10 degrees celsius as described above, the following effects are obtained: the torque is increased by about 3% and the specific fuel consumption is improved by about 1.6%.
However, as described above, in the conventional technology, since air in the engine room heated by the radiator or the engine can flow only into the intake duct together, there is a problem that vehicle performance such as torque and fuel consumption rate is lowered.

Fig. 1 is a perspective view of an air intake duct for a vehicle according to an embodiment of the present invention, and fig. 2 is a cross-sectional view of the air intake duct for a vehicle according to an embodiment of the present invention of fig. 1.
Referring to fig. 1 and 2, the vehicle intake duct 100 includes a connection portion 110 and an outside air guide portion 130, the outside air guide portion 130 extending forward from the connection portion 110 and being positioned above a radiator upper guide (upper guide), and forming an internal space into which outside air flows.
In one specific example, the outside air guide 130 may be formed of a heat insulating material, and the outside air guide 130 may be formed integrally with a radiator upper guide.
According to the present invention, a plurality of outside air inlet holes 132 through which outside air flows are formed in the lower surface of the outside air guide 130, and the plurality of outside air inlet holes 132 are formed in a plurality in the width direction of the vehicle. Further, one side surface of the outside air guide 130 includes a water inflow prevention portion 134 for preventing inflow of water, and the water inflow prevention portion 134 preferably has a stepped structure to prevent inflow of water. Therefore, the outside air flowing in through the plurality of outside air inlet holes 132 is guided to the water inflow prevention portion 134, and the inflow of water and the inflow of outside air are prevented.
In this configuration, an engine heat flux preventing portion 136 for blocking engine heat flux is provided at a side portion of the outside air guide portion 130, and the engine heat flux preventing portion 136 has a surface contact mounting structure. The lower portion of the outside air guide 130 includes a cooling upper guide 138 that blocks heat flow released from the radiator.
The intake air temperature is the temperature of the outside air entering the vehicle, and is the temperature of the air supplied to the engine via the intake system (intake duct + air filter + air hose), and the output and fuel consumption rate of the engine change according to the intake air temperature, and the structure for lowering the intake air temperature functions as follows: the heat exchanger guides the smooth inflow of outside air, blocks the heat-dissipating air of the heat exchanger, and blocks the high-temperature reverse flow of the engine room.
According to the utility model discloses an air intake duct 100 for vehicle is to reduce the intake temperature under idle speed and the driving condition and improve waterproof structure, through a plurality of outside air inflow hole 132, with the help of the wind of fan and the wind of traveling, leads to the air intake duct entry. Therefore, in order to enable such guidance, the lower surface of the intake duct guides fresh outside air that flows into a bumper grill (bumper grilles). The engine heat flux flowing in at idle blocks the inflow of engine heat flux due to the structure preventing engine heat flux.
According to the present invention, preferably, the connection portion 110 is connected to an air cleaner, and the vehicle intake duct 100 further includes a heat radiating member 150, and the heat radiating member 150 prevents a reverse flow of a heat flow of the engine, wherein the heat radiating member 150 may be a sponge pad (sponge pad). Therefore, the reverse flow of high temperature in the engine room and the heat flow released from the radiator are blocked by the left, right, and lower end structures, and the engine power and the fuel consumption rate can be improved.
On the other hand, the air filter is provided inside an engine room of the vehicle, and the air filter is provided therein, so that various dust and impurities contained in the inflow air flowing from the outside of the vehicle are filtered, and the air filter plays a role of supplying the purified air to the engine side.
According to another aspect of the present invention, an air intake system for a vehicle includes an air intake duct 100 for a vehicle, an air filter provided in the air intake duct, and an air hose that communicates the air filter with an intake manifold of an engine.
Fig. 3 is a schematic view showing a coupling structure of an intake duct for a vehicle according to an embodiment of the present invention.
Referring to fig. 1, 2, and 3 together, vehicle intake duct 100 is configured as follows: the side of the outer air guide 130 is configured to include an engine heat flow prevention part 136 blocking engine heat flow, and the air duct 100 is assembled to the trim by bolts, and is in surface contact with a four-point bolt connection (a) fastener and the cooling air guide together with the radiator guide.
In addition, according to the present invention, the lower End structure of the air intake duct 100 for a vehicle blocks the entire upper End portion of the grill, and the outside air inlet hole 132 is located in the central portion of the FEM (Front End Module).
The FEM forms a vehicle exterior as a part constituting a vehicle body, and includes a vehicle cabin and an engine room, or a trunk room and a fender, and the like, and the vehicle body is divided into a front vehicle body, a middle vehicle body, and a rear vehicle body in a longitudinal direction of the vehicle. The front vehicle body is formed with a carrier for assembling a headlight, a radiator, a capacitor, a bumper, and the like, and the headlight, the radiator, the capacitor, the bumper, and the like are assembled to the carrier together with a vehicle body panel, thereby improving assembly efficiency, reducing the number of parts to be assembled, shortening assembly time, and securing an assembly level of a product on site.
Thus, the outside air inlet hole 132 is located in the central portion of the FEM where inflow of water is relatively small, and a blocking structure is preferably used at the intake duct inlet port in order to prevent inflow of water.
Therefore, according to the present invention, the vehicle air intake duct and the vehicle air intake system including the same can directly flow outside air and suck outside air by starting the fan at idle, thereby supplying sufficient air required for the engine, improving the engine power and the fuel consumption rate, solving the high temperature problem of the intake air temperature at idle, and providing a structure in which the air intake duct and the cooling guide of the radiator are integrated, thereby reducing the cost and the weight and improving the effect of the manufacturing process.
