Detailed Description
The following description and the discussion of the embodiments of the present invention will be made more complete and less in view of the accompanying drawings, in which it is to be understood that the invention is not limited to the embodiments of the invention disclosed and that it is intended to cover all such modifications as fall within the scope of the invention.
In large cities, urban traffic roads are generally designed with a sinking tunnel (a tunnel is a passage dug in a river above the tunnel for passing trains or subways and a tunnel is used for passing vehicles below the tunnel), and once the vehicles run into the tunnel, the water in the tunnel or the tunnel instantaneously swells when heavy storm is caused, and the vehicles can be submerged by the water when the vehicles are not evacuated. In order to strive for more emergency time for personnel and internal combustion engines in the vehicle forced to enter dangerous situations, the air flow in the air inlet pipeline is changed into a transitional reverse sealing backflow supply mode from an external air suction mode along with the continuous change of the load of the internal combustion engine, and the transitional reverse sealing backflow supply mode is also called reverse sealing air inlet. When the emergency situation can not be quickly separated by continuous self-rescue in the reverse mode, starting a multidirectional sealed air inlet mode, starting a visual inspection window or an escape window, wherein the step is a multidirectional sealed air inlet mode, if the emergency situation is still in a retention state, starting a high-pressure multidirectional air supply mode (namely, the door closing detection window, the self-rescue time is prolonged to the automatic countdown of the high-pressure mode, more self-rescue time is strived for, the high-pressure sealed air supply mode can be terminated in advance according to actual conditions, all valves and internal combustion engines or engines are closed to protect the safety of the high-pressure sealed air supply mode, and then the escape window is started for escaping self-rescue.
As shown in fig. 1 and 2, the embodiment discloses an air intake and ventilation system for sealing and supplementing oxygen on a main air intake pipeline pipe body of an internal combustion engine, which comprises an air intake pipeline port 1, an air intake pipeline ball valve 2, an air intake valve controller 3, a first air intake pipeline 4, an air filter box 5, an air filter element 6, a second air intake pipeline 7, a throttle valve 8, an engine 9 and an exhaust gas exhaust pipeline 10, wherein:
the air inlet pipe orifice 1 is arranged at one end of the first air inlet pipe 4 and is gradually and outwards tightened in a circular truncated cone shape, and the design of the circular truncated cone-shaped air inlet pipe orifice 1 is beneficial to reducing air inlet noise. Conventionally, the air inlet pipe orifice 1 is arranged at the front part of the vehicle body;
the air inlet pipeline ball valve 2 is arranged in the first air inlet pipeline 4 and is close to the air inlet pipeline opening 1;
the air inlet valve controller 3 is connected with the air inlet pipeline ball valve 2 and is used for controlling the air inlet pipeline ball valve 2 to move left and right so as to open and close the air inlet pipeline port 1, for example, the air inlet pipeline port 1 is matched with the air inlet pipeline ball valve 2 to realize sealing, water sources are effectively blocked, and an internal combustion engine or an automobile engine 9 is protected in the first time, and overhaul or even scrapping is caused by the fact that incompressible liquid water and foreign matters are inhaled into an air inlet pipeline.
One end of the first air inlet pipeline 4 is communicated with the air inlet pipeline opening 1, and the other end of the first air inlet pipeline is communicated with the air filtering box 5. In this embodiment, the first air inlet pipe 4 and the air inlet pipe orifice 1 are slightly inclined downward for facilitating drainage.
The hollow filter element 6 is arranged inside the hollow filter box 5 and is used for filtering foreign matters such as leaves, insects, dust and the like remained in the first air inlet pipeline 4;
one end of the second air inlet pipeline 7 is communicated with the air filter box 5, and the other end of the second air inlet pipeline is connected with the throttle valve 8;
the throttle valve 8 is connected with the engine 9 and is used for controlling the size of air inflow; in practice, there are also several intake branches between the throttle valve 8 and the engine 9, which are used to distribute the air or oxygen for the work required for combustion, sometimes also integrated directly in the transmitter.
The exhaust gas conduit 10 is connected to the engine 9 for discharging exhaust gas. In actual operation, the tail end of the exhaust gas exhaust pipe 10 is generally designed into an n-type, m-type or u-type arc, and the height of the arc transition center (i.e. the position of the vertex) is higher than the horizontal center of the exhaust gas exhaust pipe 10. In this embodiment, the exhaust gas duct 10 preferably extends in an upwardly convex manner.
The air inlet pipe orifice 1, the first air inlet pipeline 4, the air filter box 5, the second air inlet pipeline 7, the throttle valve 8, the engine 9 and the tail gas exhaust pipeline 10 are sequentially and hermetically connected to form a first air path. In practice, there may be two groups of the intake pipe orifice 1 and the first intake pipe 4, and the two groups are mixed in the air filter box 5 after being joined, and then pass through the second intake pipe 7, the throttle valve 8, the engine 9, and the exhaust pipe 10. Alternatively, there may be two sets of the intake pipe opening 1, the first intake pipe 4, the air filter box 5, the second intake pipe 7, and the throttle valve 8, which are joined and then directly distributed to the intake manifold of the engine 9, and finally joined to the engine 9. In this embodiment, the intake pipe orifice 1 may take the form of a single port, a double port, or multiple ports, but all of this merges into the engine 9.
In another embodiment, the air inlet pipe orifice 1 is disposed close to the air filtering box 5, or the air inlet pipe orifice 1 is directly connected with the air filtering box 5 in a sealing manner. When the air inlet pipe orifice 1 is close to the air filter box 5 (i.e. the first air inlet pipe 4 is very short), the air inlet pipe ball valve 2 can be moved backwards according to different vehicle type spaces, and is installed close to the air filter box 5. When the air inlet pipe orifice 1 is directly in sealing connection with the air filter box 5 (i.e. when the first air inlet pipe 4 is omitted), the air inlet pipe ball valve 2 can be directly installed in the air filter box 5 after the installation position is moved backwards according to different vehicle type spaces.
