What the present invention relates to is the method and apparatus that a kind of cylinder of internal combustion engine injects oxygen-rich gas.The work of internal-combustion engine is fuel and the work done of airborne oxygen chemical reaction, produce power, internal-combustion engine is to obtain oxygen merely from air in the past, because stoping the oxidation effectiveness of oxygen content 21% fully not burn, airborne nitrogen 78% injects the fuel of cylinder, make fuel produce a part of carbon monoxide and hydrocarbon gas is discharged in the atmosphere, cause atmospheric pollution, make rate of energy reduce because fuel can not fully burn simultaneously.Human a large amount of internal-combustion engine that uses constantly increases the weight of for the harm of ecotope.
Traditional combustion engine is in the cylinder compresses air stage, because fuel gives oxidation with oxygen and makes gas oxygen branch drops in the cylinder under high temperature, pressure, oxygen, nitrogen percentage in the cylinder are changed, and the burning that the concentration of nitrogen improves fuel has produced the detrimental effect that stops with prolongation.
In order to address the above problem, not high at the combustion in IC engine rate, it mainly is the reason that air oxygen content 21% oxygen partial pressure in the traditional combustion engine cylinder causes inadequately, before fuel knocking fuel in the cylinder of internal combustion engine, inject the oxygen-rich gas of oxygen content 40%～95%, pressure 0.3Mpa～0.6Mpa, improve the oxygen content gas that participates in burning in the cylinder and reach 22%～28%, improve the cylinder oxygen partial pressure and utilize full combustion of fuel in the cylinder of internal combustion engine, velocity of combustion is accelerated, internal-combustion engine is run up, start favourable fast; Carbon monoxide, hydrocarbon gasifying gas amount further reduce simultaneously widely in the engine exhaust gas discharging, for further environment protection effect is played in the protection of ecotope.
At the China railways internal combustion locomotive, automobile, steamer internal-combustion engine all have the trend of quick growth.The carbon monoxide of engine exhaust exceeds standard more than 100% in some metropolitan air of China, and the people's health is caused great harm.
In view of the foregoing, the purpose of this invention is to provide the method and apparatus that a kind of cylinder of internal combustion engine injects oxygen-rich gas.The method and apparatus that cylinder of internal combustion engine of the present invention injects oxygen-rich gas is not enough in order to solve the combustion gas oxygen partial pressure that has internal-combustion engine oxygen content≤21% now, and fuel combustion is the internal-combustion engine undercapacity not to the utmost, and power consumption is big, the pollution from exhaust emission problem of environment.
The object of the present invention is achieved like this:
The method and apparatus that cylinder of internal combustion engine of the present invention injects oxygen-rich gas comprises the oxygen-rich gas nozzle 1 that is positioned in the cylinder of internal combustion engine, non-return valve for oxygen-rich gas 2, and oxygen-rich gas conveying pipe constitutes (referring to Fig. 1).
1. the method and apparatus that above-mentioned cylinder of internal combustion engine injects oxygen-rich gas has oxygen-rich gas nozzle 1 (referring to Fig. 1).
2. the non-return valve for oxygen-rich gas 2 (referring to Fig. 1) that the method and apparatus of above-mentioned cylinder of internal combustion engine injection oxygen-rich gas has the oxygen rich air nozzle to connect.
3. the oxygen-rich gas conveying pipe 3 (referring to Fig. 1) that the method and apparatus of above-mentioned cylinder of internal combustion engine injection oxygen-rich gas has non-return valve for oxygen-rich gas to connect.
Describe embodiments of the invention in detail below in conjunction with accompanying drawing:
Fig. 1 injects the structural representation of the method and apparatus of oxygen-rich gas for cylinder of internal combustion engine of the present invention.
Referring to the method and apparatus schematic representation of Fig. 1 for cylinder of internal combustion engine injection oxygen-rich gas, the oxygen-rich gas nozzle 1 among the figure in the cylinder, the non-return valve for oxygen-rich gas 2 that is connected with oxygen-rich gas nozzle, the oxygen-rich gas conveying pipe 3 that non-return valve for oxygen-rich gas connects.
Cylinder of internal combustion engine of the present invention injects the method and apparatus of oxygen-rich gas.When internal-combustion engine is started working by starting electrical machinery system drive internal-combustion engine, because the deairing step of piston is finished in the fresh air suction cylinder in the cylinder, oxygen-rich gas conveying pipe discharge pressure 0.3Mpa～0.6Mpa at the same time, the oxygen-rich gas of oxygen content 40%～95%, this moment is because cylinder pressure is lower than the pressure in the oxygen-rich gas conveying pipe, the spring of non-return valve for oxygen-rich gas is transferred pressure and promotes to open safety check, oxygen-rich gas flows to oxygen-rich gas nozzle, sprays rapidly and uniformly to be injected in the cylinder of internal combustion engine.The pressure of adjusting oxygen-rich gas conveying pipe according to observing and controlling oxygen-rich gas content injects cylinder with the concentration of oxygen content 40%～95%, make knocking fuel before in the cylinder oxygen content gas reach 22%～28%.When piston is put when mobile to knocking fuel, because piston is to the compression of gas, when making pressure in the cylinder and oxygen-rich gas discharge pressure balance because the effect closure of check ring of spring, stop high pressure gas leakage that blast produces to the import of oxygen enrichment safety check to oxygen-rich gas conveying pipe.
Its step of work embodiment of the method and apparatus of the cylinder of internal combustion engine injection oxygen-rich gas of foregoing invention is as follows:
1. begin to start when internal-combustion engine, start-up system drives piston and begins periodic motion, and when the exhaust terminal hour, the pressure in the cylinder is minimum≤0.1Mpa, the spring of non-return valve for oxygen-rich gas is to safety check total pressure≤0.1Mpa/cm
2, to make a concerted effort less than the pressure of oxygen conveying pipe for these two, a plurality of apertures that non-return valve core is opened oxygen-rich gas process oxygen-rich gas nozzle evenly are injected in the cylinder fast.
2. above-mentioned oxygen-rich gas injects the process of cylinder, when piston continues to move to charge firing point, and the existing gas in the Piston Compression cylinder, when cylinder gas pressure was brought up to the oxygen-rich gas conveying pipe balance, safety check cut out under the pressure effect of spring.
3. close back piston at non-return valve for oxygen-rich gas and continue compression cylinder gas, the total core of oxygen enrichment safety check is pressed tightlyer, better tightness; When reaching knocking fuel, a large amount of heat energy of generation, the pressure of cylinder raises, because that the non-return valve for oxygen-rich gas core is under pressure is bigger, sealing is qualified, stops pressurized gas to non-return valve for oxygen-rich gas and oxygen-rich gas conveying pipe leakage.
4. the traditional combustion engine cylinder is when burning work, and each cycle waste gas is always arranged endless, and these waste gas are nonflammable compositions, also have CO
2, nitrogen, water vapour is because these gases residual makes oxygen in the gas gross in the cylinder be significantly less than the partial pressure of oxygen in the atmosphere.Make knocking fuel cause the not intact situation of fuel combustion.Because internal-combustion engine oxygenation burning, working condition changes greatly.
5. because the cylinder continuous operation, temperature reaches several Baidu, the Piston Compression air under high temperature pressure, fuel at this moment with airborne oxygen pre-oxidation, the gas oxygen partial pressure is further reduced cause burning not to the utmost, at this moment delay be exactly unsurmountable in burning.Increasing oxygen-rich gas in cylinder of internal combustion engine before the fuel knocking fuel makes gas componant percentage oxygen content in the cylinder reach 22%～28% abundant knocking fuel that helps fuel.
6. injecting oxygen-rich gas one before the fuel knocking fuel in cylinder is the oxygen content percentage situation that changes cylinder, bring up to oxygen content to 22%～28%, the oxygen that makes burning need is more abundant, allow full combustion of fuel, and velocity of combustion also can be accelerated widely, in the fuel-saving while, improve the performance of internal-combustion engine.
7. supply with the oxygen rich air scale of construction when not enough when detecting according to TT﹠C system, the oxygen-rich gas oxygen content percentage of the pressure of adjustment oxygen-rich gas conveying pipe and adjustment oxygen-rich gas conveying pipe is to 40%～95% high-load, make that the further raising of partial pressure of oxygen reaches oxygen content 22%～28% in the cylinder, at this moment the working condition of internal-combustion engine just improves widely.
Cylinder of internal combustion engine of the present invention injects the method and apparatus of oxygen-rich gas, is the combustion position that improves internal-combustion engine for further, and carbon monoxide is further reduced, and hydrocarbon further reduces.The present invention 1 is bad for solving burning, and carbon monoxide, hydrocarbon are to harm human and environment in the exhaust gas discharged; The 2nd, burn fully at fuel, make bigger merit; The 3rd, improve the efficient of internal-combustion engine, under the situation with power, engine size, weight are littler; The 4th, cost of production is not high in the process of transforming traditional combustion engine, easy processing.
