Description
Technical Field
The present application relates to an intake system of a vehicle, and more particularly, to an intake pressure control device, an intake system, and a vehicle.
Background
The front deck arrangement of modern vehicles is becoming more compact, so that the intake air lines are becoming more complex and the intake pressure drop is greater than in previous engines. And the lower torque of the engine under the condition of low speed is always the soft rib of the small-displacement engine. Even if many engines are equipped with conventional turbochargers, the power performance at low engine speeds due to the slow response of the turbocharger is often not satisfactory.
SUMMERY OF THE UTILITY MODEL
Therefore, in view of the above circumstances, the present application provides an intake pressure control apparatus for conveniently and quickly raising an intake pressure when necessary, so that a power performance of an engine at a low rotation speed can be improved. According to the utility model discloses, the disclosed admission pressure control device of this application includes: a boost mechanism secured within the intake conduit; an air intake portion disposed outside the air intake duct; and a drive element disposed outside the intake duct and configured to drive the supercharging mechanism, wherein the supercharging mechanism is fixedly connected to the intake section such that gas enters the supercharging mechanism from the intake section, and the shape of the cross section of the supercharging mechanism corresponds to the shape of the cross section of the intake duct.
According to some embodiments of the present application, an intake pressure control apparatus is disclosed, wherein the supercharging mechanism is configured as a bladeless fan.
According to some embodiments of the present application, an intake pressure control apparatus is disclosed, wherein the bladeless fan is configured as an annular bladeless fan.
According to some embodiments of the present disclosure, the annular bladeless fan has an outer diameter configured to correspond to an inner diameter of the intake duct.
According to the intake pressure control apparatus disclosed in some embodiments of the present application, the supercharging mechanism is fixed in the intake duct after the air cleaner in the direction of intake air.
According to some embodiments of the present application, an intake pressure control apparatus is disclosed, in which a gas filter mechanism is provided between the intake portion and the supercharging mechanism.
According to the intake pressure control apparatus disclosed in some embodiments of the present application, the driving element controllably drives the supercharging mechanism in accordance with the current speed, load of the engine and the current intake pressure in the intake pipe.
According to a second aspect of the present application, there is disclosed an intake system including an intake air pressure control device as in any one of the above embodiments.
According to a third aspect of the present application, there is disclosed a vehicle including an intake air pressure control apparatus according to any one of the above embodiments.
Drawings
The above and other objects and advantages of the present invention will be more fully apparent from the following detailed description taken in conjunction with the accompanying drawings, in which like or similar elements are designated with like reference numerals.
FIG. 1 schematically illustrates an intake air pressure control apparatus according to the present disclosure; and
fig. 2 schematically shows the installation position of the supercharging mechanism according to the present application in the intake duct.
Detailed Description
Fig. 1 schematically illustrates an intake pressure control apparatus 10 according to the present disclosure. As can be seen from fig. 1, the intake pressure control apparatus 10 includes: a supercharging mechanism 1, an intake section 2 and a drive element 3. The supercharging mechanism 1 is fixed in an intake duct 100, and the intake section 2 and the drive element 3 are arranged outside the intake duct 100. In particular, the drive element 3 is designed to drive the charging mechanism 1, while the charging mechanism 1 is fixedly connected to the intake section 2, for example by means of a snap-in connection, so that gas enters the charging mechanism 1 from the intake section 2 and the shape of the cross section of the charging mechanism 1 corresponds to the shape of the cross section of the intake duct 100.
Preferably, in the intake pressure control device 10 disclosed in the present application, the supercharging mechanism 1 is configured as a bladeless fan. The bladeless fan has no fan blades, so that the bladeless fan can be used for supercharging air inlet when in need, and the resistance of air flow cannot be increased due to the structure of the blades when in no need of supercharging. Therefore, the bladeless fan can be connected in series in the air inlet pipeline to conveniently and quickly realize a supercharging function, and the resistance to air inlet is reduced when the bladeless fan does not work.
Preferably, the bladeless fan is configured as a ring-shaped bladeless fan. And more preferably, the outer diameter of the annular bladeless fan is configured to conform to the inner diameter of the air inlet duct. This structure can further reduce the intake resistance of gas in the intake duct, thereby improving intake efficiency.
Alternatively, as shown in fig. 1 and 2, in the intake pressure control device disclosed in the present application, the supercharging mechanism 1 is fixed in the intake duct after the air cleaner 200 in the direction 101 of intake air.
Here, preferably, in the intake pressure control apparatus disclosed in the present application, a gas filtering mechanism (not shown in the drawings) is provided between the intake portion 2 and the supercharging mechanism 1. The gas filtering mechanism can filter impurities in gas entering the gas inlet part.
In the intake pressure control device disclosed in the present application, the drive element 3 preferably drives the supercharging mechanism 1 in a controlled manner as a function of the current speed of rotation of the engine, the load and the current intake pressure in the intake tract 100. Specifically, for example, in the case where the engine speed is low, in order to obtain a high prevailing torque, the engine control module may control the rotational speed of the driving element 3 of the supercharging mechanism 1, for example, the motor, based on the current engine speed, load, and intake pressure measured by an intake pressure sensor in the intake pipe, so as to control the supercharging mechanism 1 by the driving element 3 to increase the intake pressure.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
