Description

Method for fully burning in internal combustion engine
Technical Field
The invention relates in particular to a method for achieving a sufficient combustion in an internal combustion engine.
Background
Modern internal combustion engines burn with air as a fixed quantity and fuel quantity formulated by air-fuel ratio. The air-fuel ratio itself is not a perfectly accurate ratio, and is a balance estimated ratio. It is sufficiently unlikely that combustion will reach one hundred percent. In order to increase the kinetic energy of the engine, technologies such as turbocharging and mechanical supercharging are developed, the method increases the intake of air in a unit space, and the oxygen amount is increased in a phase change manner. However, the method does not change the oxygen amount in the air, and belongs to an excess air method.
The combustion method using natural air as an oxidant is natural combustion. Modern internal combustion engines are based on the principle of natural combustion. When the internal combustion engine is burned in air, a large amount of nitrogen oxides are generated at a high temperature based on 80% of nitrogen content in air, and the reaction of the generated nitrogen oxides absorbs heat, and the nitrogen oxides and carbon monoxide are discharged as exhaust gas, which becomes an important source of harmful gases such as haze and global warming.
In view of the above, the present invention provides a new method for achieving a sufficient combustion in an internal combustion engine.
Disclosure of Invention
The invention aims to provide a method for fully combusting in an internal combustion engine, which takes high-concentration oxygen as a combustion improver, achieves the purpose of controlling the combustion state of fuel by controlling oxygen, can fully combust the oxygen and the fuel in the internal combustion engine, reduces the discharge which can not be fully combusted, and achieves the purposes of energy increment and emission reduction.
In order to realize the purpose, the adopted technical scheme is as follows:
a method for fully burning in the internal-combustion engine, set up the air nitrogen filter in the air intake pipe between internal-combustion engine and air filter, make the gas not containing nitrogen as the combustion-supporting gas, enter the cylinder block of the said internal-combustion engine, make the fuel burn;
the fuel is natural gas, gasoline and diesel oil;
the temperature at combustion is greater than the ignition point of the fuel.
Further, the air nitrogen filter is arranged on an air inlet pipeline between a throttle valve of the internal combustion engine and the air filter opening.
Furthermore, when the piston, the cylinder and the cooling system cylinder in the internal combustion engine cannot bear the temperature generated by the fuel combustion value, the air nitrogen filter adjusts the oxygen intake according to the temperature which can be borne by the piston, the cylinder and the cooling system cylinder space of the internal combustion engine; the rest cylinder space is filled with air or oxygen.
The cylinder, piston and cooling system of the engine can not meet the requirement of complete combustion of fuel, and pure oxygen less than the required oxygen-fuel ratio can be used for entering the cylinder of the engine, so that the oxygen required by combustion reaction is greatly increased, and the nitrogen content of air naturally reduced is correspondingly reduced. The heat absorption effect and incomplete combustion of the generated nitrogen oxides are correspondingly reduced, and compared with the prior internal combustion engine technology, the method not only completes the energization under the same unit fuel combustion, but also realizes the emission reduction.
Furthermore, when the cylinder, the piston and the cylinder space of the cooling system of the internal combustion engine can bear the temperature generated by the fuel combustion value, the oxygen amount is calculated according to the oxygen combustion ratio, and the oxygen intake amount is controlled by the air nitrogen filter.
The engine cylinder, the piston and the cooling system can meet the requirement of the complete combustion temperature of the fuel, and sufficient oxygen or excessive oxygen is sent to the engine cylinder through the air nitrogen filter to be completely oxidized and combusted with the fuel, so that no natural air enters. The engine cylinder body is a closed space, fuel basically achieves a complete combustion effect, no nitrogen oxide is generated without participation of nitrogen, and carbon monoxide and other incomplete combustion products are basically not generated under the condition that the oxygen content is higher or even exceeds. The method is the most ideal condition of combustion of the internal combustion engine, and avoids the internal combustion engine as one of the sources of haze generation.
When the space between the cylinder and the piston of the internal combustion engine does not satisfy the space required for reaching the fuel combustion value temperature and nitrogen oxides are not generated, the volume of the cylinder is calculated according to the exhaust gas volume of the internal combustion engine, and the amount of oxygen entering the cylinder is controlled by a nitrogen filter. The existing engine does not produce harmful gas.
Further, the nitrogen-free gas contains oxygen and inert gas, and the content of the oxygen is more than 90%.
Compared with the prior art, the invention has the advantages that:
the invention takes pure oxygen as combustion-supporting gas, and the pure oxygen filtered by the air filter and fuel are mixed and combusted in the internal combustion engine, so that natural air does not participate in combustion in the cylinder body any more, and nitrogen oxides are not generated any more; or the air inflow is reduced, the oxygen amount is increased, the nitrogen content is reduced, and the nitrogen oxide is reduced. The combustion state of the combustible in the whole combustion process is controlled by controlling the input amount of oxygen in the combustion process, so that the fuel can be completely or fully combusted, and energy increasing and emission reduction are realized.

Detailed Description
To further illustrate the method of the present invention for achieving a sufficient combustion in an internal combustion engine to achieve the desired objects, the following detailed description is given with reference to the preferred embodiments of a method of achieving a sufficient combustion in an internal combustion engine according to the present invention, and the detailed description, the structure, the features and the effects thereof. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Before describing in detail a method of the present invention for achieving a sufficient combustion in an internal combustion engine, it is necessary to further describe the related method mentioned in the present invention to achieve a better effect.
(1) The following are definitions and explanations of terms appearing in the book:
internal combustion engine: the term "normal internal combustion engine" means an ordinary internal combustion engine using air as an oxidizing agent, and does not include a special engine such as a rocket engine.
Oxygen-fuel ratio: the molecular molar ratio is calculated from the molar mass ratio, and the ratio of oxygen to fuel is called the oxygen-fuel ratio. Such as natural gas CH4,2O2+CH4＝CO2+2H2O, the molar ratio is 2:1, the molar mass ratio is 64:16, and the oxygen-fuel ratio is 4. Gasoline is 27O2+2C8H22864:228, 3.79. Diesel C12H34The oxygen-fuel ratio was 3.47.
Oxygen is a combustion improver. Oxygen is widely distributed in air, and reaches 20 percent of the total mass, and is the largest energy source in the world. The vast majority of combustion is oxidative combustion. The amount of oxygen required for complete combustion is greater than the amount of fuel. To achieve complete combustion, the oxygen to fuel ratio is typically greater than 3. In the case of combustion using air, however, complete combustion of the fuel is impossible. Only when oxygen is used as a combustion improver, oxygen with a controllable variable is used for combustion with fuel, and the intake of oxygen is controlled according to the oxygen-fuel ratio. The excess of oxygen does not pollute the air, while the excess of fuel produces exhaust gases and harmful gases due to incomplete combustion. Controlling the amount of oxygen ingested allows control of the size of the complete combustion.
Oxygen enrichment: it means that the oxygen consumption is larger than the oxygen content in natural air and smaller than the oxygen content of complete combustion.
Oxygen content: the oxygen consumption reaches the oxygen consumption of complete combustion.
Excess oxygen: the amount of oxygen used exceeds the amount of oxygen used for complete combustion.
A nitrogen filter: the nitrogen filter uses molecular sieve type oxygenerator (psa type oxygenerator) technology. Pressure swing adsorption nitrogen filtration oxygen production. The zeolite molecular sieve is adopted, and the adsorption force of the molecular sieve to nitrogen molecules in air under certain pressure is far greater than that of oxygen molecules. By improving the technology, a getter system through which only oxygen molecules pass is obtained. The two molecular sieves in a group are alternately matched with a pneumatic valve to be opened and closed in a circulating manner, nitrogen is adsorbed by pressurization, and nitrogen is discharged by decompression. And completing the nitrogen-oxygen separation. Thereby increasing the purity of the oxygen for combustion.
Industrial oxygen generation: refers to pure oxygen in this application, i.e., air without nitrogen. The air which is obtained after being filtered by the nitrogen filter and does not contain nitrogen has the oxygen purity of more than 90 percent and contains trace inert gases.
(2) Taking a four-cylinder 2.0-displacement gasoline engine as an example, the temperature which can be borne by the cylinder body is as follows:
the known conditions are:
the volume of the monomer cylinder is 0.5 liter, and the air mass is 0.6 g; the air-fuel ratio is 14.7, and the amount of the gasoline used for one time in a single cylinder is 0.041 g; the oxygen-fuel ratio is 3.79; the calorific value (combustion value) of the gasoline is 43070 KJ/KG; constant value, constant volume and specific heat capacity: air cv is 0.717, oxygen cv is 0.661; the temperature of the engine cylinder after compression (500 ℃ C. and 700 ℃ C.), here, 600 ℃ is used; the thermal efficiency of the engine is 38%.
The existing engine can be normally used within 2100 ℃ of instantaneous temperature; the temperature at the top of the piston does not exceed 400 ℃ and the piston can be normally used.
The air mass is 1.2 g/l; the oxygen mass was 1.325 g/l.
The theoretical temperature of the existing engine is 43070 multiplied by 0.41 divided by 0.717 divided by 0.6+600 ═ 4704 ℃;
if the engine heat conversion rate is 38% in the actual situation, the temperature in the cylinder should be 4704 ℃x38% 1787 ℃, which is consistent with the current engine situation.
Temperature calculation of engine to reach combustion value:
the oil is 0.041 g, and the oxygen is 0.041 x 3.79-0.155 g according to the oxygen-fuel ratio.
The volume of oxygen is 0.155 ÷ 1.32 ÷ 0.117 liter, and the volume of the cylinder can produce a combustion value temperature of 43070 × 0.041 ÷ 0.661+600 ═ 23433 ℃; according to the heat efficiency of the modern engine, 23433 multiplied by 38 percent is 8904 ℃, and the instant temperature cannot be borne by the existing engine.
The cylinder volume of 0.117 liters is one quarter of the cylinder volume of 0.5 liters.
In order to adapt to the temperature which can be borne by a modern engine, air can be added to serve as a filling agent, or the temperature of oxygen is increased to reach the temperature which can be borne by a cylinder body, and the oxygen content of the air serving as the filling agent is negligible and the air is used as excess oxygen. The harm of air as a filler is that NO will be generatedXCompounds, which absorb heat and pollute the air, but at no cost. The use of excess oxygen as a filler is costly but pollution-free.
For the expansion work, the line pitch of 0.117 liter and 0.5 liter cylinders is 4 times of the line pitch of 0.5 piston, and the work conversion rate is 4 times.
(3) Efficiency of
The prior art uses an air-fuel ratio, and the invention uses an oxygen-fuel ratio or a ratio slightly lower than the oxygen-fuel ratio.
The oxygen-fuel ratio and the air-fuel specific heat energy conversion efficiency are compared in table 1.
TABLE 1
Figure BDA0002677785890000051
From this table 1 it can be seen that the prior art is not sufficiently combustible, with at least 50% of natural gas, 23% of gasoline, 17% of diesel not participating in the oxidation reaction, which does not include the reaction to generate nitrogen oxides.
With the understanding of the related art methods referred to in this disclosure, a method of the present invention for achieving a sufficient combustion in an internal combustion engine will now be described in further detail with reference to specific examples:
the technical scheme of the invention is as follows:
a method for fully burning in the internal-combustion engine, set up the air nitrogen filter in the air intake pipe between internal-combustion engine and air filter, make the gas not containing nitrogen as the combustion-supporting gas, enter the cylinder block of the said internal-combustion engine, make the fuel burn;
the fuel is natural gas, gasoline and diesel oil;
the temperature at combustion is greater than the ignition point of the fuel.
Preferably, the air nitrogen filter is arranged on an air inlet pipeline between a throttle valve of the internal combustion engine and the air filtering port.
Preferably, when the piston, the cylinder and the cooling system cylinder in the internal combustion engine cannot bear the temperature generated by the fuel combustion value, the oxygen generated by the nitrogen filter is added on the air inlet pipeline between the engine and the air filtering system and enters the cylinder to share the air inlet pipeline with the air. According to the temperature which can be born by the piston, the cylinder body and the cylinder body space of the cooling system of the internal combustion engine, the air nitrogen filter is used for adjusting the oxygen intake; the rest cylinder space is filled with air or oxygen. The air is used as filler for cooling, absorbing heat and increasing the space to enter the cylinder body in the residual space.
The oxygen intake is less than the amount of oxygen required to achieve the oxygen-fuel ratio per cylinder. The pure oxygen inlet amount is regulated and controlled according to the temperature which can be borne by the cylinder body and the piston, and the air is used as a filling agent for reducing the temperature, absorbing heat and increasing the space to enter the cylinder body in the residual space. This method is to increase the oxygen content per unit volume, not the increased intake air amount of turbocharging, and belongs to the oxygen-enriched combustion (as shown in fig. 1). In this process, air acts as a bulking agent and temperature reducing agent to enlarge the space.
Preferably, when the cylinder, the piston and the cylinder space of the cooling system of the internal combustion engine can bear the temperature generated by the fuel combustion value, the oxygen amount is calculated according to the oxygen combustion ratio, and the oxygen intake amount is controlled by the air nitrogen filter. This is either full-oxygen combustion or excessive-oxygen combustion. Eventually, combustion without natural air (as shown in fig. 2) is achieved.
When the engine cylinder, the piston and the cooling system can meet the temperature requirement of reaching the combustion value, a nitrogen filtering system is arranged between the engine and the air filtering system. The air filtering system directly becomes a filter of the nitrogen filtering system, the oxygen intake is calculated by an oxygen-fuel ratio formula to obtain the oxygen consumption, and then the oxygen is filtered and enters the engine cylinder for combustion. Can be adjusted to be full oxygen combustion or excess oxygen full combustion. The combustion method is an ideal combustion mode, and no natural air is involved, a large amount of nitrogen is not generated, and no nitrogen oxide is discharged.
Preferably, when the space between the cylinder and the piston of the internal combustion engine does not satisfy the space required for reaching the fuel combustion value temperature and nitrogen oxide is not required to be generated, the volume of the cylinder is calculated according to the exhaust gas volume of the internal combustion engine, and the amount of oxygen entering the cylinder is controlled by the nitrogen filter. The fuel intake is calculated according to the temperature which can be borne by the engine, the piston, the cylinder and the cooling system cylinder space instead of air, and the excess oxygen combustion belongs to the category.
The engine, the cylinder body, the piston space and the cooling system can not meet the requirement of high temperature generated by the fuel combustion value and can not meet the requirement of environmental protection. Industrial pure oxygen is directly input from the nitrogen filter to replace air. The fuel intake is based on the temperature that the engine, cylinder, piston space, cooling system, can withstand. Since oxygen replaces air, no nitrogen is present and there is no endothermic reaction. The fuel is completely combusted. Only water, carbon dioxide and oxygen that has not been burned off are discharged.
Preferably, the nitrogen-free gas contains oxygen and inert gas, and the content of oxygen is more than 90%.
Example 1:
the Beijing modern way of the 2.0 displacement wins, and the related equipment installation:
the air inlet pipeline between the engine and the air filtering system is firstly punched, the oxygen conveying pipe is installed, the other end of the oxygen conveying pipe is sealed, namely the nitrogen filtering system connected with the vehicle-mounted power supply is obtained, and the air filtering system can start to be used for getting on the road.
And stopping at the roadside to start the operation under the condition of testing the neutral idle speed, starting the nitrogen filtering system and metering according to the nitrogen filtering system. At this time, the gas treated by the nitrogen filtering system is a gas without nitrogen, and the oxygen content is more than 90%, which can be used as pure oxygen.
Raising the pure oxygen generation from 1 liter per minute to 5 liters per minute in one minute, wherein the engine speed is substantially unchanged; then the speed of the engine is increased from 800 revolutions to 1700 revolutions rapidly after the speed is increased from 5 liters per minute to 10 liters per minute in one minute; the oxygen output is increased to 12 liters, the engine speed is rapidly increased to 2100 revolutions, then the engine speed begins to fall back to 1700 revolutions, and then the engine speed is increased from 1700 revolutions to 2100 revolutions, and the cycle is repeated.
On-road experiments show that the oxygen output of the nitrogen filter is adjusted to 10 liters per minute during first-gear idling, the vehicle speed starts to rise, the rotating speed rapidly approaches 2100 from 800, the rotating speed drops back to 1700 after reaching 2100 revolutions, the rotating speed rises to 2100 from 1700, the same circulation effect as that during idling is generated, and the circulation is observed to last more than ten times, so that the stable and unchangeable circulation can be determined.
Second gear idle driving, the basic situation being substantially close to first gear idle, only the vehicle speed is raised, also resulting in a cycle of 1700 to 2100 revolutions.
Through the above experiments, it can be analyzed that the oil supply amount of the idle speed is limited, when the idle speed reaches 2100 revolutions, the oil is completely burnt, the oxygen supply amount is more, the upper limit only reaches the energy of 2100 revolutions, the revolution speed is increased from 800 revolutions to 2100 revolutions, and the idle revolution speed is increased by more than 250%.
Closing the oxygen supply of the nitrogen filtering system, stabilizing the accelerator at 2000 revolutions, punching the nitrogen filter, increasing the oxygen supply to 10 liters per minute, increasing the rotation speed to 2500, increasing the oxygen supply to 20 liters per minute, increasing the rotation speed to 3500 revolutions, and beginning to fall back to the cycle. The rotating speed increasing stage belongs to oxygen-enriched combustion.
Example 2.
Destructive type experiment:
the motorcycle of Jialing 70 model is started, the neutral rotation speed is 4000 turns, the accelerator position is fixed, and black smoke and noise are discharged in the process of stably accelerating for three minutes.
And then the blood was extinguished for 20 minutes and then the blood was stopped, and the performance was consistent with the previous performance.
And (3) opening a nitrogen filter, inputting pure oxygen of 15 liters per minute into an air inlet pipe of the running motorcycle, freezing the accelerator to the previous 4000-turn position, rapidly increasing the rotating speed from 4000-turn to 7000-turn, and continuously running for 3 minutes. The engine generates huge noise in the running process and discharges light white smoke.
The motorcycle is extinguished for 20 minutes, and then the motorcycle cannot be started normally, and the cylinder is damaged.
This example demonstrates that the engine block cannot withstand temperatures that have not reached combustion values.
Example 3.
Gas/gasoline oxygen cutting machine
The principle of the gas and gasoline oxygen cutting machine is the same, only the fuel is different, the gasoline type needs to pressurize the oil storage tank before using, three control valves on the cutting gun, the fuel valve, the oxygen mixing valve, the oxygen blowing valve, the nitrogen filter and the air filter are integrated.
The method comprises the following specific operations:
the fuel valve is opened first, the combustion degree is controlled well, and black smoke is seen slightly. The steel plate is burned by the combustion flame for 3 minutes without too much reaction, at the moment, a nitrogen filtering system is opened for supplying oxygen, the oxygen mixing valve is regulated to a better oxygen combustion proportion to start cutting, and meanwhile, an oxygen blowing valve is opened (the oxygen blowing valve has the function of blowing away molten metal, and the excessive oxygen cannot influence combustion). After only a few seconds, the steel plate is melted, and the cutting machine can work normally to cut the steel plate. The cutting machine has the advantages that operators work for a long time, the operators cannot generate uncomfortable reactions such as unsmooth breathing and the like, and the cutting device does not generate any toxic and harmful gas and has little influence on the gas environment.
The oxygen cutting machine has a combustion operation principle similar to that of the internal combustion engine (the combustion operation principle is shown in fig. 3), and the mixed oxygen combustion and the carburetor cylinder injection air suction combustion have the same principle, but one is in-cylinder combustion and the other is naked combustion. A sealed metal tank is arranged at the head of the cutting gun, an exhaust pressure reducing valve is additionally arranged at the other head of the cutting gun, the simple internal combustion engine is obtained, and the temperature of the cutting gun head can reach 3000 ℃.
Example 4.
The dual-purpose vehicle is superior to oil gas and 2.0-displacement vehicle, natural gas is used for combustion, the vehicle runs at the first-gear idle speed, and the rotating speed is 800 revolutions. At the moment, the nitrogen filtering system is opened to supply oxygen, the oxygen amount is increased to 5 liters per minute, the rotating speed of the engine is still 800 revolutions at the moment, the oxygen amount is increased to 10 liters per minute, the rotating speed of the engine is still unchanged, and the oxygen amount is increased to 20 liters per minute and still remains unchanged. This indicates that the combustion gases have been burned dry in the cylinder and are not affected by the additional intake of oxygen. The combustion cannot be intensified by the addition of oxygen, and in this case, the combustion is conducted with excess oxygen.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
