Embodiment 1

[0033] figure 1 It is a structural schematic diagram of an engine air intake system provided by this application. The engine air intake system includes a main air intake system 3, an electronic control unit 4, an air intake flow meter 5, a supplementary air flow meter 6 and an auxiliary air intake link. It is used to ventilate the engine 1. Each cylinder of the engine 1 is equipped with a cylinder intake manifold 2, and the main intake system 3 is provided with multiple air outlets, and the multiple air outlets correspond to the intake manifolds of multiple cylinders respectively. 2 is connected to the intake end of the cylinder, and the compressed air is fed into each cylinder through the cylinder intake manifold 2; Air supply solenoid valve 7, intercooler 8, cooling pipeline 9, first air outlet solenoid valve 11 and compressed air storage tank 12.

[0034]Wherein, the intake air flow meter 5 is electrically connected with the electronic control unit 4 and communicated with ...

Embodiment 2

[0040] On the basis of embodiment 1:

[0041] The auxiliary air intake link also includes an air storage box 13 and a second air outlet electromagnetic valve 14 communicated with the air storage box 13, the air intake end of the air storage box 13 is communicated with the outlet end of the first air outlet electromagnetic valve 11; The valve 14 is electrically connected with the electronic control unit 4, and its air outlet is connected with the air inlet of the cooling pipeline 9. The electronic control unit 4 makes the compressed air in the compressed air storage tank 12 flow into the storage tank by controlling the first air outlet solenoid valve 11. Storage is carried out in the air tank 13, when the power of the engine 1 is insufficient and the intake air volume needs to be increased, the compressed air pre-stored between the first air outlet solenoid valve 11 and the air supply solenoid valve 7 and the compressed air in the air storage tank 13 are in the cooling pipe Whe...

Embodiment 3

[0043] On the basis of embodiment 1:

[0044] The embodiment of the present application also provides an engine, on which the aforementioned engine air intake system is installed, the compressed air prestored in the engine air intake system can be directly aligned with the cylinder intake manifold 2 to supply air to the engine 1, and there is no Time delay, and merge with the compressed air of the existing main air intake system 3, so that the engine 1 has enough air for combustion, and the acceleration performance of the engine 1 can be improved to the greatest extent. Therefore, the engine does not need to work at full load for a long time, which reduces the possibility of overheating of the engine, thereby reducing the wear of the internal parts of the engine and prolonging the service life of the engine to a certain extent.

Abstract

The present application relates to an engine air intake system, an engine, a vehicle and an air intake method, and relates to the technical field of engines. The auxiliary air intake chain includes a supplementary air solenoid valve, an intercooler, a cooling pipeline, a first air outlet solenoid valve and a compressed air storage tank which are sequentially communicated with the cylinder intake manifold. The meter, the air supplement solenoid valve, the first air outlet solenoid valve and the compressed air storage tank are respectively electrically connected to the electronic control unit; when the engine power is insufficient and the intake air volume needs to be increased, it will assist the main intake system to supply air to the engine, namely The pre-stored compressed air can be directly aimed at the cylinder intake manifold to supply air to the engine. This intake method has the shortest distance and the fastest time, and the compressed air storage tank can directly provide the compressed air required by the engine. Therefore, this application It can not only improve the actual air intake of the engine and the acceleration performance of the whole vehicle.

Description

technical field [0001] The present application relates to the technical field of engines, in particular to an engine intake system, an engine, a vehicle and an intake method. Background technique [0002] When a car is driving in a plateau area, its power will weaken with the increase of altitude. The reason is that the high altitude and low air pressure in the plateau area will reduce the intake air volume of the engine and insufficient fuel combustion, which will directly lead to a decrease in vehicle power and fuel consumption. Increase; and as the altitude increases, the air pressure gradually decreases, and the air density becomes smaller and smaller, resulting in less and less air intake of the engine and lower power performance. Among them, every 1000m increase in altitude, the atmospheric pressure drops About 11.5%, the air density is reduced by about 9%, and the car power will drop by about 10%. However, due to the decline in engine power and the decline in vehicle...
