Embodiment 1

[0033] Such as figure 1 , the present invention proposes a parallel automobile engine air intake system, including an engine 1, an air intake pipe 2 and an air filter 3, and also includes a body, which is included on the air intake pipe 2 of an existing naturally aspirated engine or the air filter A bypass air inlet is opened on the shell of the air outlet 301 side of the cleaner 3 to connect the outlet of the air supercharger 5; the inlet of the above air supercharger 5 is connected with a second air filter 501 to form a natural air intake The main body of the system and the supercharged intake system work in parallel; the operating state of the above-mentioned air supercharger 5 is controlled by the operating state of the above-mentioned engine 1 .

[0034] Since the air supercharger 5 takes in air through the second air filter 501 installed by itself, it avoids the defect of insufficient air intake caused by sharing an air filter with the original natural air intake system....

Embodiment 2

[0040] Such as figure 2 The above-mentioned air supercharger 5 is driven by electricity, and the above-mentioned air supercharger 5 is arranged at one end of the water tank of the engine.

[0041] At this time, the air input by the engine air inlet 102 flows through the radiator of the engine 1 and then enters the engine 1 . This structure can not only dissipate heat from the water tank, but also increase the intake air temperature.

[0042] The motor 502 of the above-mentioned air supercharger 5 is connected to the storage battery 103 through a special-purpose controller 7, and the throttle sensor or the throttle mechanism displacement sensor or the engine speed sensor is connected to the special-purpose controller 7 to control the motor 502 of the above-mentioned air supercharger 5 speed.

[0043] The air booster 5 is driven by a motor 502 , which is electrically connected to the battery 103 ; a controller 7 is connected in series between the motor 502 and the battery 103...

Embodiment 3

[0049] Such as image 3 , the output end of the generator 101 of the above-mentioned engine 1 is divided into two paths, one path is directly connected to the motor 502 of the above-mentioned air supercharger 5, and the other path is connected to the engine battery 103 through the isolator 6.

[0050] Above-mentioned air supercharger 5 is driven by motor 502, and the output terminal of generator 101 is electrically connected with the positive pole of motor 502 and storage battery 103 respectively, and isolator 6 is also connected in series between generator 101 and storage battery 103; The motor 502 is electrically connected. The above-mentioned isolator 6 is a one-way conductive isolator.

[0051] This structure adopts the way that the generator 101 directly supplies power to the motor 502 , and controls the start-stop and speed of the air supercharger 5 through the current and voltage changes of the generator 101 .

[0052] This structure enables the generator 101 to not o...

Abstract

The invention provides a parallel automobile engine air intake system. The parallel automobile engine air intake system comprises a body. The body comprises a bypass air inlet which is formed in an air intake pipe of an existing natural air intake engine or formed in a shell at one side of an air outlet of an air filter, and the bypass air inlet is connected with an outlet of an air supercharger; and an inlet of the air supercharger is connected with a second air filter, and thus the body with a natural air intake system and a supercharging air intake system working in parallel is formed. According to the parallel automobile engine air intake system, the air supercharger is additionally arranged and is made to operate in parallel with the original natural air intake system in parallel, so that air inflow of an engine is increased, and under the conditions that safety is guaranteed and energy consumption is reduced, pollution is reduced, and the output power of the engine is increased. Meanwhile, since the air supercharger can be driven by a small-power motor, an excessive load, caused by the air supercharger, to an existing automobile power generation system is avoided, and production cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an engine intake system. Background technique [0002] Existing engine intake systems are mainly natural intake and turbocharged intake, and turbocharged is divided into exhaust gas drive and electric drive. [0003] The disadvantage of the natural air intake system is: insufficient air intake, especially when the engine is running at high speed, the intake air flow increases, and the filter resistance increases with the increase of air flow, resulting in insufficient air supply, reduced engine efficiency, and serious exhaust pollution. [0004] In the turbocharged air intake system, the disadvantages of exhaust gas-driven turbocharging are: high engine temperature, there is a risk of spontaneous combustion, and the low-speed effect is not obvious. The disadvantage of the electric drive turbocharging system is: in order to meet the needs of the high-speed operati...
