Description
Technical field
The machine-building auto industry field.
Background technique
International oil prices, inevitably leads to a series of topics between cars and fuel, and diesel vehicles difficult to enter the big cities in China, is one of the most difficult to resolve one of the things people; background of this issue: the global oil resources growing shortages and rising automobile consumption, alternative energy sources in the search for the ultimate before, the world automobile manufacturers, energy companies and the government are exploring delaying oil crisis of the middle line: diesel engines to reduce carbon dioxide emissions than gasoline engines of 30% to 45% , other harmful gas emissions, diesel engines also have a distinct advantage, especially in Europe increasingly harsh carbon dioxide emissions, diesel engines than gasoline engines reduced by nearly 45% of carbon dioxide emissions, which is very impressive data, and saving 25% ~ 30%, becoming the various manufacturers and respected research objectives; And because diesel engine has low speed high torque at 0 ~ 100Km / h speed range acceleration, superior performance, are suitable for use metropolitan traffic jams.
The data display in the end of the year 2010, Chinese vehicle guaranteeding organic quantity be probably at least at 5,800 ten thousand, and with about 1,500 ten thousand speed increase in every year.Fuel oil for vehicles consumes conservative estimation at 13,050 ten thousand tons; Account for 1/2 of annual CNPC total amount consumed; If Chinese Motor Vehicle has 20% to use diesel engine; Then use 2,350 ten thousand tons of fuel oils less; Traffic capital consumption just can be saved about 70,600,000,000 yuans; Minimizing is to the dependence of Imported oil, for the world wide energy-saving and emission-reduction contribute.
Diesel instead of gasoline can save energy 25% to 30%, China could save tens of billions a year or even one hundred billion yuan of funds, so that's a good thing for all to see, why the diesel engine is not quick to grow? What is it restricted the diesel engine applications? Urban air engine is considered to be one of the main sources of particulate, diesel particulate complex composition and particle size is very small, most of the particles are sub-micron and nano-sized particles, suspended after discharge in the atmosphere for a long time, people breathe this suspension thing to have done great harm to human body; diesel exhaust particulate concentrations several times higher than gasoline; tiny particles suspended in the atmosphere, reducing the atmospheric visibility, if they are inhaled can cause respiratory disease, and even cancer; using diesel increase in the proportion that can lead to serious environmental pollution; controlling emissions of harmful gases generated during combustion, is the ideal way to purify emissions.
In the diesel engine vent gas, the mass content of soot particulate, the soluble organic constituent mass fraction in particulate matter and the chemical composition of soluble organic constituent.Experiment draws in the diesel engine vent gas content of soot particulate: 32.6～143.6mg/m
3The mass fraction of soluble organic constituent in particulate matter is 18.5%～89.4%.Analyze the reason that diesel engine produces soot particulate: one, be burning under the anoxia condition; This problem is by the TDI motor of modern science and technology research and development; Fuel injection quantity control very accurately; The oil sprayer that TDI adopts is by electromagnetic valve; Injection timing and fuel injection quantity; Can be come accurately control by the instruction that solenoid valve sends according to ECU, this is general like petrolic electric jet technology.Moreover; The TDI motor can also be realized the closed loop control of diesel engine; This does not have in traditional diesel engine; Sensing elements such as lambda sensor feed back to ECU with the tail gas situation; Thereby can judge combustion position according to tail gas; And then further adjust fuel delivery, realize the excess oxygen burning; Though be under excess oxygen two; But owing to motor casing wall, piston are in the circulation state of cooling all the time; During the engine operation oil spout; When mist of oil is sprayed onto piston, casing surface; Piston, casing surface temperature are lower than the firing point of diesel oil, carbon granule; Promptly be lower than the oxidation reaction threshold value of carbon granule, the carbon granule firing point: 550 degrees centigrade.Therefore, temperature did not reach the oxidizing reaction temperature of carbon when the carbon granule that mist of oil decomposites collided piston face, cylinder surface, and carbon granule can not be oxidized.This situation is especially more obvious when engine cold starts.
For solving the carbon granule emission problem, Europe forces to take the vent systems carbon granule to filter, and the diesel oil vehicle all has been equipped with the carbon granule recovering device, and free carbon regnition catalytic combustion, to reduce the carbon granule discharging; China's engineering bound pair diesel motor exhaust purifies and adopts mechanical filter, catalytic reaction and electrostatic separation technique that tail gas is carried out purified treatment.Major character is that three-way catalytic converter is made the laminated board type structure; Ceramic filtering body is rolled into by inside and outside two-layer cup-shaped cover; Electric heater is that temperature self-compensation is to reach the oxidation of coal temperature; High-voltage electrostatic dust separator is provided with the I and II catcher; Catcher is a hole storage formula structure; The electrode flow spoiler is housed, filter, reactor on its centre electrode.Not thorough with tail gas clean-up in the method solution conventional art, and the problem of utensil easy blocking.Otherwise taken by a filter coated with an alloy of precious metal catalyst and the metal fiber sheet metal bracket welded or assembled film winding compartment together, rolled into a sheet metal stent geometry, metal foil coated with a noble metal catalyst and metal stents fiber membrane filter made of laminated intervals, the exhaust gas stream passing through the bracket slot by means of exhaust gas pressure, produce changes direction, the air is forced through the side of the high permeability of the metal fiber membrane, so that soot particles trapped by the metal fiber membrane after combustion engine to solve the problem of carbon particulate emissions, these techniques can only be carbon particles in the exhaust system in a combustion engine, whereby the heat generated does not participate in doing useful work, thermal pollution of the environment and wasted effort CO
2 emissions.
Explosive motor carbon granule catalytic combustion system before the present invention all is to be placed in outside the engine exhaust port without exception, because the oxidate temperature of carbon soot particles is up to 550～600 ℃, and the delivery temperature of diesel-oil vehicle is 175～400 ℃.In order to reduce the carbon-smoke combustion temperature, the way of one of them solution just is to use, and is the DPF of base with the catalyzer.The catalyzer that in DPF, uses should demonstrate good activity, stability and durability under actual operating conditions.Although the scientist of each advanced country of the world through exploration and the research of three more than ten years, do not find as yet a kind of as the three-way catalyst that petrol engine is used highly effective oxidize soot catalyzer.
Utilize the indoor catalyst for catalytic combustion ion injection method of combustion in IC engine of the present invention; Make carbon granule fully in the engine combustion Indoor Combustion; The energy of carbon granule burning all is used for doing work; Therefore; This technology improves the combustion efficiency of diesel oil; When amount of fuel is identical, improve the power output of diesel engine; When exporting same power, can reduce the use amount of diesel oil, energy saving.Diesel oil burns more fully, means that also noxious gas emission reduces, and reduces atmospheric pollution.Because in-engine free carbon sufficient combustion, reduce the engine component carbon distribution, reduce mechanical wear, reduce lubricant pollution, can prolong lubricant oil working life; Reduce motor inlet and outlet door carbon distribution, can prevent motor gas leakage, keep engine output, the prolongation with service time does not reduce, and then prolongs the working life of diesel engine.
Catalytic combustion improves the sensitive response degree of diesel engine, the air diffusion speed ratio vapour of diesel oil by slowly many, the velocity of combustion of diesel oil also than gasoline slowly many, this be diesel engine than petrol engine safety, be difficult for the internal factor that produces nature, burns vehicle; Diesel engine can not come the inspiration mixed gas through air-intake negative-pressure as petrol engine, but need spray in the cylinder through the diesel oil of high pressure oil pump with atomizing, could fully mix with air.Because the firing point of diesel oil is low; Oxidation reaction threshold ratio gasoline is high a lot; This speed that makes the diesel oil mixed gas light will be slower than gasoline mixture, and it is that the diesel combustion characteristic causes that conventional diesel engine low-response, low temperature ignition difficulties, diesel-oil vehicle always slow half clapped.The indoor ion injecting catalyst of diesel combustion can reduce diesel oil, reach and dissociate, the threshold of reaction of carbon burning, and therefore, catalytic combustion can increase the reaction velocity of diesel engine, makes the diesel engine response time near petrol engine.When catalytic combustion can make red light such as diesel-oil vehicle start,, be active in one's movements as petrol engine.
Catalytic combustion can reduce the diesel knock amplitude; Because the property difference of diesel oil and gasoline; Cause the global design and the petrol engine of diesel engine different fully, traditional diesel engine moment of torsion is very big, and reliability is also very high; But power is little and; Its vibrating noise is big, and diesel engine is started by compression-ignition, just at the end of compression stroke; Compressed air produces after the High Temperature High Pressure, and oil pump sprays into spontaneous combustion in the cylinder with diesel oil with vaporific.This " igniting " just is equivalent to pinking if mode occurs on the petrol engine.In fact, the pinking of diesel engine is that inevitably it need lean on this mode to realize lighting of mixture.Diesel engine why shake with noise obviously greater than petrol engine, mainly just be based on this reason.Do not hope to see for any internal-combustion engine of pinking itself.For diesel engine, its igniting relies on pinking, but hopes then that as the Designer this pinking is controlled at the transition point that can light a fire and gets final product.Unnecessary pinking can increase vibrations and noise naturally, and even influences working efficiency.But shock wave moment of pinking is extinguished the oil gas burning; Produce not clean-burning hydrocarbon, free carbon; And these fuel are when running in the motor transition metal oxide catalyst; Can continue oxidizing fire expansion acting; Promptly improve the utilization ratio of fuel; Can reduce the intermittent time of acting again, prolong the endurance of doing manual work, the pinking amplitude is reduced.
