Description
Technical field:
The invention relates to the clean-burning environmental protection of mixed oil and gas in the spark plug engine inner casing, efficient, power-saving technology.
Background technology:
The power of automobile is from engine, and the generation of engine power is to utilize the explosive power that burning produced of gas mixture in the cylinder to promote piston.At present because the Power Limitation of spark plug engine, most of automobile is in the process of advancing, the gasoline concentration (oil gas ratio Fuel-Air Ratio) of the gas mixture in the spark plug engine is excessive and can't fully burn, making pollution emission seriously reach noise increases, the automobile oil consumption increases also thereby widely, causes the vehicle fuel expense to rise, power reduces, the speed of a motor vehicle and efficient reduction.More because gasoline combustion is insufficient, make the intravital carbon distribution of cylinder increase, thereby the power of engine is reduced, the wearing and tearing of engine strengthen, and cause the life-span of engine to be reduced, and bring a lot of worries so just for the automobile owner, have increased more trouble and worry.
Engine is in the circulation of air inlet each time, compression, outburst, four strokes of exhaust, and the oil gas incendiary time, we can generally be divided into it igniting, burning, extinguishing three phases much smaller than 0.01 second:
One, igniting: when oil supply system is sent into the oil gas that mixes in the cylinder, after Piston Compression, ignition system just can transmit electric current to sparking plug, utilizes the electrion of dipolar of the sparking plug oil gas that ignites.The oxidising process that this oil gas ignites is called " igniting ".
Two, burning: after igniting was finished, flame just began outwards to propagate with the form of combustion pressure ripple, and the mode of its propagation is to be the center with the sparking plug, in layer outwards burning in regular turn.At flame when propagating all round, burn and unburned oil gas between, the reaction zone that carries out combustion oxidation reaction is arranged, we claim that this is " a flame wavefront ".The range size of this flame wavefront influences the speed of incendiary speed of reaction and inner cylinder pressure rising.Oil gas incendiary speed has decisive influence to the performance of engine, and incendiary speed is fast more, and the performance of engine is good more, and the trend that pinking takes place is also low more.
Three, extinguishing: when combustion wave passed to cylinder wall, the temperature of flame just descended at once, make near the combustion wave cylinder wall oxygenizement thereby slow down even interrupt, and the oxidizing reaction that this eases up has just produced the product HC and the CO of incomplete oxidation.We are called " extinguishing layer " zone that this oxidizing reaction is slowed down, and the extinguishing layer is more little, and it is few more that the heat of expression cylinder passes loss amount, and the thermo-efficiency of engine is higher, it is bigger to exert oneself.Flame more can be near wall, and the extinguishing layer is just thin more, and is just few more by the gas volume of extinguishing.In addition, the roughness that reduces the combustion chamber also can reduce extinguishing amount and hot biography amount, improves thermo-efficiency.
The determining positions of sparking plug finish under the identical combustionvelocity required time of burning.The distance of sparking plug and cylinder wall is near more, and it is short more then to finish the incendiary time.Because oil gas incendiary process also is the topmost heating of engine, pressure process, length during this period of time directly has influence on the thermo-efficiency of engine, also has influence on the trend of pinking.The optimum position of sparking plug is exactly the central authorities in the combustion chamber, and in order to reach this design, the design of many valves and the twin cam shaft trend that is inevitable.
Pinking is the incendiary some oil gas that is called as " tail gas " (End Gas) compressive action that the back gas expansion caused of being burnt in the end, its volume-diminished, temperature and pressure are raise, before combustion wave does not pass to this place as yet, the temperature of this tail gas has reached behind the spontaneous ignition temperature and burning voluntarily, and the speed with 300m/s～200m/s is outwards propagated rapidly, when the pressure wave of the pressure wave of trouble-free burning and this spontaneous combustion meets, because direction is opposite, produce violent gas pulsation, and send distinctive metal strike note, so be called " pinking ".If have carbon distribution can influence the heat radiation of combustion chamber in the combustion chamber and cause the raising of compression ratio, allow the engine that pinking can not take place originally that pinking also takes place.After pinking continues for some time, will make piston, cylinder head, porthole, piston ring etc. to produce serious damage.
The abnormal combustion phenomenon that " pinking " is in the engine combustion process to be produced, it and produces knock, reduces engine and exert oneself, damage engine structure except making the engine vibration aggravation.Can the say so natural enemy of engine designer of pinking, many designs that promote horsepower, reduction oil consumption, reduce pollution, as high compression ratio, supercharging device, raising cylinder wall working temperature (progress of material science and technology makes does not have anxiety on the intensity) etc., all be restricted because of the generation of pinking.
The anti-knock of fuel is to represent with octane value (Octane Number), is the most important quality pointer of motor spirit, and adopting octane promoter is the important means that improves the motor spirit octane value.Tetraethyllead began to use in motor spirit in nineteen twenty-three, be until nineteen fifty-nine by the octane enhancing additive of the unique use of people.Along with the needs of automobile emission control and protection environment, be limited in the world and added lead alkylide in the gasoline, and realized that progressively low leadization of gasoline is with unleaded.Nineteen fifty-nine, U.S. a company released methyl cyclopentyl-dialkyl-tricarbon manganium (MMT) to market, and as the auxiliary octane promoter of tetraethyllead, this agent has improved gasoline octane rating effectively.But have research to think, MMT forms the porousness settling at the engine combustion chamber internal surface, makes the spark plug lost of life, and the U.S. was in inactive MMT in 1978.Methyl alcohol, ethanol, methyl tertiary butyl ether and the trimethyl carbinol abroad appear the seventies in 20 century, they all have quite high unleaded octane rating and blending octane value, but they exist vapo(u)rability, mutual solubility, corrodibility, toxicity and problems such as exhaust gas emission and economy respectively.
MTBE generally uses in the whole world as gasoline dope, it can not only effectively improve gasoline octane rating, and can also improve automotive performance, reduces CO content in the exhaust, reduce the gasoline production cost simultaneously, world's gasoline uses the MTBE annual capacity above 2,100 ten thousand tons at present.But MTBE can cause chronic pollution to the water source, and the American Studies personnel find MTBE seriously polluted to tap water by inquiry.This compound remains in the down-hole can form persistent harm, even ban use of in a very long time behind the MTBE, it will remain in continues in the water source to pollute.California, USA is served as reasons with polluted water, bans use of MTBE, and also there is similar action in American National environmental protection department.So far, Europe and Asia still do not have any purpose of forbidding MTBE, and particularly MTBE demand in Asia increases fast, and China is domestic at a large amount of these additives that use now.
Current, there are factors such as octane value is low, olefin(e) centent is high, peace and quiet function is low in China's gasoline, only is example with the white gasoline, and according to the emission request of Europe III, Europe IV, sulphur content is 0.003%, and olefin(e) centent is 10%.In fact, sulphur content is up to 0.08% in China's white gasoline, and olefin(e) centent is up to 40%-50%, with 2 class oil standard (sulphur contents 0.02% in world's fuel oil standard; Olefin(e) centent 20%) still there is a big difference.Although the emission level of most new cars will with international basic synchronization, but practical situation have to yield to the reality that standard of fuel falls behind relatively, cause " because of oil decreases car ", have hindered stomach just as having eaten thing.
