Description

Air-filtering and oxygen-enriching device for automobile

The utility model relates to a kind of automobile fil, and particularly a kind of energy produces oxygen-abundant automobile filtering and oxygen-enriching device.

Existing automobile filter, it mainly is the tiny grit in the filtered air, and feasible purer air admission carburetter and gasoline mixed firing, down conventional, nitrogenous in the air is 79%, containing oxygen is 21%, no matter automobile is the EFI car, or carburettor car, no matter automobile is a luxury car, or common car, the air percentum that enters driving engine is nitrogen 79%, oxygen 21%, for sufficient oxygen is provided to automotive engine, increase the power of driving engine or fuel can be burnt more fully, prior art can only increase ozone, the scientific worker who has, utilize aerodynamic principle to make into the air inlet trunnion to make inlet air to produce the whirl chamber of eddy current shape air-flow, the purpose that inlet air increases is oxygenation, the nitrogen amount that the result causes entering in proportion also increases thereupon, nitrogen is the principal element that influences vehicle fuel economy, the increase of nitrogen can make the economy of motor vehicle fuel be affected, and has also just increased the quantity discharged of burning back Nitrogen oxides, and this can cause the pollution to environment again.

In view of this, how to break through the pattern and the notion of traditional raising sufficient combustion, not to increase amount of air merely to increase oxygen, but improve enter gas level of oxygen, reduce the content of nitrogen in the suction quantity, adjusted the percentum that enters oxygen and nitrogen in the air, increase amount of oxygen with this, improve the sufficiency of burning, increase the tractive performance of automobile, fuel saving reduces the discharging of harmful tail gas, this is that numerous automotive research personnel wish the problem of capturing for a long time, also this novel wound motivation place of grinding just.

The utility model designer relies on the practical experience of being engaged in the research of automobile nine operating mode distribution correlative technology fields decades, on the basis of feasibility study test repeatedly, designs air filtration plant one air-filtering and oxygen-enriching device for automobile of novel concept.

At the deficiencies in the prior art, this later-model purpose is a kind of device of design, can will enter nitrogen and oxygen separation in the engine air, and make a large amount of oxygen enter automobile carburetter and fuel mix burning, and make a large amount of nitrogen be prevented from entering the device of automotive engine.

Principle of the present utility model is to utilize pressure swing adsorption method, based on molecular sieve airborne oxygen, nitrogen composition is optionally adsorbed, and makes airborne nitrogen, oxygen produce to separate and obtains oxygen rich gas; Be specially, when air compresses through turbocharger, when being provided with the adsorbed layer of molecular sieve, nitrogen molecular preferentially by the molecular sieve adsorption in the jar, stay in the gas phase by oxygen molecule, and become oxygen rich gas, and oxygen rich gas is delivered to carburetter and fuel mix by pipeline; When molecular sieve adsorption nitrogen reaches capacity, utilize decompression, vacuum technology, the nitrogen molecular that the molecular sieve surface is adsorbed is driven away, recover the adsorption power of molecular sieve, be provided with skies that many groups have molecular sieve and divide jar, each group is provided with three electromagnetic valves, accurately by the time adsorb, desorb, switch groups time continuous the operation can provide the oxygen rich gas of certain flow continuously; The utility model has been innovated a new notion makes automobile improve sufficiency, fuel-economizing and the reduction tail gas pollution of fuel combustion, also is that the revolution in the technical field is polluted in automobile fuel saving, reduction.

The purpose of this utility model can be by following realization, the utility model feature is the air compressor that is connected turbocharger by the air inlet dust filter, air compressor connects cold-trap, the compressed air duct of cold-trap connects many groups sky arranged side by side and divides jar, every group of empty jar that divides is provided with three electromagnetic valves, and three electromagnetic valves connect compressed air piping, oxygen rich gas pipeline and nitrogen pipeline respectively.The other end of above-mentioned nitrogen pipeline is connected to vacuum generator; The turbine of turbocharger can directly be connected with the motor vehicle exhaust emission pipe.

The notion of chemically correct fuel is exactly that sufficient oxygen realizes that fuel burns completely, contain nitrogen in the gas when reason that reality is not accomplished is exactly burning, gas when the utility model makes burning just is close to purity oxygen, supply to each operating mode oxygen consuming amount in nine operating modes of automobile realizes that science provides accurately, really realized chemically correct fuel, and be not only empty talk, realized the long-awaited automobile gas supply system new century of auto technology circle, broken through a forbidden zone of auto technology.

It is huge and can't be used for the automobile of finite space that the utility model overcomes pressure swing adsorption technique equipment in the existing oxygenerating technology, and utilize 40% work of expansion in the vehicle exhaust, offer turbocharger, the air compressor of driving turbocharger produces pressurized air, utilizes empty branch jar that pressurized air is carried out oxygen nitrogen again and separates, and can adopt microcomputerized control, empty jar and the electromagnetic valve of dividing of many groups, high-speed oxygen, it is little to reach volume, and oxygen making amount is big; The utility model is owing to be to utilize vehicle exhaust to drive the propulsion source turbocharger, embodied that the design is flexible, volume is little, and can and control suction quantity with nine operating mode automatically regulating oxygen-supplying amounts of automotive operation speed; The utility model has reduced the quantity discharged of Nitrogen oxides in the tail gas especially, is reduced to minimum quantity discharged for hydronitrogen and hydrocarbon, helps environmental protection and control atmosphere pollution.
