The oxygen-rich air produced by the oxygen generating device is input into the oxygen storing device, the oxygen-rich air in the pot is under the pressure, and is sent to the carburetor by a conveying pipe to be mixed with the ethanol to form the combustible ethanol gas mixture, the combustible ethanol gas mixture is inhaled into the cylinder by the self-absorption of the engine, thus the oxygen ratio in the ethanol gas mixture is improved, and the oxygen is supplied for the loss of the expansion air and the residual exhaust gas in the cylinder due to the rising cylinder temperature, the ethanol combustion speed can be accelerated by using the oxygen breathing characteristic, so that the ethanol in the engine can fully burn to make the engine work.

Description

Utilize the air-breathing ethanol engine of hyperoxia

Technical field

The utility model relates to a kind of engine power generating means, specifically, relates to a kind of ethanol that utilizes fully and acts as a fuel, and is aided with the air-breathing new work engine of hyperoxia.

Background technique

At present, all motors are power with gasoline or diesel oil all.Being exactly ethanol petrol, also only is the ethanol of having converted 10%-20% in gasoline.Can not use ethanol to be fully as the reason of fuel:

The calorific value of ethanol is low, is 3000000kj/kg, is 65% of gasoline, because calorific value is low, caused being short of power of motor, so, fuel made as using ethanol fully, just must strengthen the delivery volume of ethanol in theory, make identically, could equally with petrol engine do work with the calorific value of gasoline.But engine cylinder is constant volume combustion, has strengthened the use amount of ethanol in the cylinder, will reduce the amount of air in the cylinder, little air, ethanol just can not fully burn, and its calorific value is lower, and the power of motor also reduces.

Its two, during engine operation, cylinder temperature raises, intake temperature reaches 400 degree, and the air that enters in the engine cylinder will be met thermal expansion, claims the cylinder expansion air, during the motor acting, just only can be full of the air after the expansion in the cylinder.

According to ideal gas equation: p1*V1/T1=P2*V2/T2

The identical V1 cylinder of P1=P2 cylinder pressure charge volume V2 cylinder expansion volume of air

T thermodynamic temperature, (degree centigrade+273.15) cylinder intake temperature are 400 degree

V2＝(T2/T1)V1＝(400+273.15/273.15)V1＝2.46V1

Learn thus: cylinder temperature 400 degree that raise, in the cylinder air expansion 2.46 times.

According to the material density formula: P=M/V P density M quality V volume

The density of air is that the oxygen content of 1.29 air is 21%

1 cubic metre air weight: 1000 liters of * 1.29=1290 grams

The oxygen content of 1 cubic metres of air: 1290*21%=270.9 gram

Since in the cylinder air expansion 2.46 times, 1 cubic metre volume of air=2.46 cubic metre, air expansion mass conservation, 2.46 cubic metres expanded air still be 1290 to restrain; And 1 cubic metre expanded air weight is: the 1290/2.46=524.4 gram, the oxygen content of 1 cubic metre of expanded air is: 524.4*21%=110 gram, the oxygen content in 1 cubic metre the cylinder expansion air have only 110 grams.In addition: when the each exhaust of motor stops, owing to the gas pressure of reason cylinders such as exhaust resistance is higher than the about 110MP of barometric pressure.Nearly 10% waste gas remains in the cylinder, and residual air is oxygen-free.When the each air inlet of cylinder stopped, the air in the cylinder was exactly that 10% residual gas adds the expanded air sum that enters.1 cube of expanded air is in the cylinder: 524.4 grams-52.4 grams=472. grams, 472/21=99.1 gram oxygen, the combustion ratio of gasoline: the expanded air of 14.7: the 1 cylinders 472 gram/14.7=32.1 that can only burn, the gasoline institute work of 1 cubic metres of air burning: 46000000*87.75/1000=403650 joule, but burns gasoline institute work in the motor in fact: 46000000*32.1/1000=147660 joule.The motor that is to say any discharge capacity reaches 147660 joules in the fuel oil work of unit time internal combustion just can make normal working of engine.

The model utility content

The purpose of this utility model is can't adopt ethanol to act as a fuel fully at available engine, can not better realize the deficiency of effects of energy saving and emission reduction, provides a kind of ethanol that utilizes fully to act as a fuel, and is aided with the new work engine of oxygenized air combustion supporting simultaneously.Because the air fuel ratio of ethanol is: 9: 1,1290/9=143.33 gram, 1 cubic metre air can burn 143.33 the gram ethanol approximate 143 the gram, the calorific value of ethanol is 3000000Kj/kg, 1 cube of ethanol calorific value that air burnt: 3000000*143/1000=429000 joule, and one cubic metre cylinder expansion air, the 52.4 gram ethanol 472/9=52.4 grams that can only burn, 1 gram ethanol perfect combustion needs 1.89 gram oxygen, 270.9/143.33=1.89 reaching 147660 joules just needs 49.2 gram ethanol.147660*1000/3000000=49.2 gram, and 1 cube of cylinder expansion air, the 52.4 gram ethanol that can burn.The density of ethanol is 0.8.The catch fire excess air of concentration of mixed gas lower limit is 1.4, and the catch fire excess air of concentration of the upper limit is 0.4.The excess air of catching fire the lower limit of ethanol compares: 1.4*9=12.6: 1, and the air ratio of the upper limit: 0.4*9=3.6: 1,52.4/0.8=65.5,52.4 gram ethanol are in the cylinder air volume, and are just too thin.1 cubic metre/65.5=15.2 is 15.2: 1.The lower limit that the has surpassed mixed gas concentration of catching fire.Ethanol can not burn.As restraining ethanol chemically correct fuels, 472/143.3=3.3 with 143.33 at 1 cube of cylinder expansion air.It is 3.3: 1.Concentration of alcohol is too dense again in the mixed gas, has surpassed the mixed gas upper limit concentration of catching fire, and the ethanol mixed gas can't burn.As want the ethanol burning, the ethanol consumption is selected 9: 1 volume mixture gas ratio for use.1 cube/9=111*0.8=88.8 gram, air fuel ratio is 472/88.8=5.3, is 5.3: 1, can burn.And 88.8 gram ethanol institute works are: the 3000000*88.8/1000=266400 joule, can satisfy the needs that motor uses power fully.And 88.8 gram ethanol burnings just need 167.8 gram oxygen, 88.8*1.89=167.8.Every cubic metre of cylinder expansion air will add 88.7 gram oxygen 187.8-99.1=88.7 and 36.4 gram ethanol 88.8-52.4=36.4.Just can satisfy the required power of motor.Oxygenerator is as long as production contains 36% oxygen-enriched air like this, and 472*36%=169.9 restrains oxygen, uses for engine combustion.

The technical solution of the utility model is: a kind of air-breathing ethanol engine of hyperoxia that utilizes, described motor comprises an oxygen generator, the storage oxygen device that is connected with oxygen generator, and the mixed oxygen device of fuel that oxygen is mixed with ethanol, mix the oxygen device and be connected with cylinder.

Preferably, the mixed oxygen device of described fuel is a Carburetor.

Preferably, be provided with one-way flow valves between described oxygen generator and the storage oxygen device.

Preferably, on oxygen generator, be provided with drive by motor self power and carry compressed-air actuated blower to oxygen generator.

The beneficial effects of the utility model are: the utility model utilization directly increases the mode of oxygen-enriched air in motor, the needs of motor ethanol burning under various loads have been satisfied, reached the purpose of using the renewable sources of energy, and the air quality waste gas that influences that comprises in the ethanol of the sufficient combustion gas of discharging also reduces greatly, and its environment protection effect is also very obvious.The latent heat of vaporization of ethanol is than higher, and when burning in conventional cylinder, it is slow to catch fire, and causes the engine start ignition difficulties, but owing to give the oxygen of having annotated in the engine cylinder, has utilized the combustion-supporting property of oxygen, has accelerated the velocity of combustion of ethanol.The boiling point of ethanol is low, and the self-priming motor common may produce vapour lock, but the oxygen-enriched air in oxygenation combustion-supporting apparatus of the present invention has pressure, and oxygen pressure can break through the low vapour lock that forms of boiling point.The octane value of ethanol can improve the compression ratio of cylinder than higher, increases the power of motor.So, on the motor of Carburetor,, be successful fully with the method for oxygen enriching burning-aid.
