Description
The present invention relates to the method and apparatus that a kind of petrol engine utilizes energy-saving double-fuel.
Well-known methyl alcohol can be used as the substitute fuel of motor.And method and form that it is used as Dai Ran have multiple.Wherein, a kind of methanol decomposition method (having another name called methyl alcohol upgrading method) being arranged, is at first methyl alcohol to be passed through reactor, utilizes exhaust heat to carry out catalytic pyrolysis, and then with the dissociated methanol gas (hydrogen-rich gas) that produces in the cracking, introduces motor and act as a fuel.This method can not only Dai Ran, but also can be energy-conservation.For example U.S. Pat 4366782, US4418653, day patent JP60-3472 and Deutsches Reichs-Patent DT2717993 etc.They have carried out a large amount of deep researchs to this.Their research approach is on traditional petrol engine, with the whole gasoline replacings of dissociated methanol gas, usefulness methanol decomposition-feeding system gasoline replacing feeding system.Though the technical feasibility of this scheme, and can avoid motor because of with the methanol liquid be fuel produce such as methyl alcohol toxicity, aldehydes pollute, problems such as parts corrosion and wearing and tearing aggravation, in existing technique device, remain in following shortcoming:
1, the methanol decomposition amount is big, and the engine exhaust heat is limited.When motor turns round, can not satisfy the needs of cracking technology far away to delivery temperature and heat under normal revolution-middle-low load working condition.
2, starting a cold engine difficulty.
3, power descends obviously, only is about 70% of pure Fuel Petroleum.In patent US4418653 and JP60-3472,, be to adopt the method that increases methanol liquid to solve in order to remedy the deficiency of power.But this has taken place again because of being the shortcoming that fuel brings with the methanol liquid.Employed fuel in patent US4418653 has also used Fuel Petroleum except that methanol liquid, methanol vapor and dissociated methanol gas.When its uses gasoline, Close All and stop the methanol decomposition feeding system, therefore, even the participation of Fuel Petroleum can not fundamentally solve because of being that fuel makes the obviously problem of decline of power with the dissociated methanol gas.
4, abnormal combustion and pinking easily take place; The engine operating status instability.
5, financial cost height.Though energy-saving effect is arranged, because the lower calorific value of methyl alcohol only is 48% of a gasoline, produce the corresponding power that is equivalent to gasoline in order to make motor, then must consume at double in the quantity of methyl alcohol (weight) of gasoline.The consumption of general methyl alcohol is 1.4-1.8 a times of gasoline.
6, catalyst amount is big, and active lifetime is not good enough.Cumbersome overlapping to the configuration of catalyzer in patent US4366782, influenced usability.
7, lack the safety protection facility.
Just because of above shortcoming, cause the prior art of dissociated methanol gas method not produce due benefit in practice improving engine thermal efficiency, reducing specific fuel consumption and methyl alcohol for aspect the combustion.
In addition, we know, the motor petrol motor is in communications and transportation, most time is to work under middle-low load working condition.This is to cause that the motor specific fuel consumption increases, less economical one of the main reasons.For the specific fuel consumption under the middle-low load working condition that reduces motor, what generally adopt in the prior art is the partly scheme of cylinder that kills engine.For example U.S. Pat 4192276 and Chinese patent CN8510365 etc.These technology for the engine main body parts change big, complex structure, cost is higher.So be difficult to application in practice.
The objective of the invention is to provide a kind of new method and apparatus.This method and apparatus not only can make dissociated methanol gas fully, stably supply motor to act as a fuel.And to utilize the excellent specific property of cracking gas, under the normal revolution-middle-low load working condition of motor, realize lean combustion.Reach energy-conservation, reduce the purpose of polluting, utilizing the alcohols substitute fuel with this.
Structure of apparatus of the present invention and principle (seeing accompanying drawing 1)
On traditional reciprocating piston type four-stroke gasoline engine (hereinafter to be referred as petrol engine or motor).Under the situation of not doing to change, implement the bifuel system of present technique at main structural component.Wherein the fuel of system is made up of gasoline and dissociated methanol gas.The addition ratio of gasoline is that 70-50%(is heavy), dissociated methanol gas is that 30-50%(is heavy).Because motor car engine is in the work of reality, under varying load condition, turn round, and most time is to turn round under middle-low load working condition, therefore for the dynamic property of bringing into play gasoline combustion and the lean combustion characteristic of dissociated methanol gas, so that both addition ratios all can be adjustable at random in the scope of 0-80%.The device of system is two fuel tank dual circuit structures.Promptly on the basis of original gasoline feeding system of motor, on the intake and exhaust pipeline, set up a cover methanol decomposition-feeding device.Its device feature is made up of methyl alcohol storage tank 19, methyl alcohol evaporation-superheater 12, reactor 9, cooler 34 and mixer 29 and supporting pump, valve, pipeline.Its methyl alcohol Deep Catalytic Cracking process is: methyl alcohol is flowed out by storage tank (pure case), through a pure pump 17(or a methyl alcohol high position) force feed enters the methyl alcohol vaporizer-superheater, and evaporating gasification and becoming about 250 ℃ of superheated vapor.Then enter in the tubulation of reactor 9, on the bed of catalyzer, temperature 280-420 ℃, pressure 1-3bar carry out catalytic reaction.The dissociated methanol gas that produces in the reaction enters cooler (34) voltage stabilizing of lowering the temperature immediately, makes temperature＜55 ℃.Pressure 1-1.2bar.Enter mixer 29 through modulating valve 32 again then, with the air mixing that enters by the mouth of pipe 36.Enter after the mixing in the suction tude 21, mix mutually with gasoline-air again from Carburetor.Last gasoline-dissociated methanol gas-air enters cylinder simultaneously as motor fuel.And required heat in the methanol decomposition is all supplied with by exhaust heat.Its exhaust approach is: after engine exhaust is drawn by outlet pipe 6, controlled by thermosensitive element 40, shunted automatically, after the reactor catalysis bed tempertaure surpasses 420 ℃ by diverter valve 38, the blind off a line passage of 6b of diverter valve makes most waste gas directly be discharged into atmosphere by pipeline 6a.When temperature was lower than 280 ℃, the passage of the 6a that then blinds off a line made the major part of waste gas enter cracking system and reactor and evaporation-superheater and carries out heat exchange; By heat exchange exhaust gas temperature is reduced, last waste gas is by outside the tail pipe discharge machine.Thermosensitive element not only will be controlled the reactor catalysis bed tempertaure by the switching of valve 38 simultaneously, the activity of guard catalyst and life-span, but also to control methyl alcohol valve 39.When catalytic bed temperature is lower than 280 ℃, make methyl alcohol valve 39 be in closed condition automatically, stop the conveying of methyl alcohol.When surpassing 280 ℃, make methyl alcohol valve 39 be in open state, open manually operated valve 18 and pure pump 17 this moment and can force feed methyl alcohol enter cracking system and carry out catalytic pyrolysis.The dissociated methanol gas that is produced uses for motor fuel after cooler storage, voltage stabilizing, cooling.For the sake of security, in cooler, be provided with pressure transducer or pressure electromagnetic device controller.When the pressure of cracking gas in cooler surpassed predetermined value, controller can close methyl alcohol valve 39 by circuit automatically, stops the conveying supply of methyl alcohol.In addition be provided with two valves between cooler and mixer 29, one is manually operated valve, can regulate the flow of cracking gas; Another is the pressure limiting check valve, and its function is to make cracking gas voltage stabilizing, current stabilization, unidirectional conveying, prevents the fluctuation of cracking gas and reverse tempering etc.
Secondly, methyl alcohol used catalyzer in catalytic pyrolysis is a low temperature copper zinc class, also available high temperature zinc chrome type or palladium, platinum, type etc.Methyl alcohol at the reaction equation of catalytic pyrolysis is: (1)
When containing moisture content in the methyl alcohol, its reaction equation is: (2)
Wherein methyl alcohol permission water content is the 0-29%(volume), optimum moisture content is the 6-12%(volume).Approximately per kilogram methyl alcohol adds 0.5 kg of water, can produce 0.188 kilogram hydrogen.Because the difference of cracking technology, the cleavage rate of methyl alcohol is in the scope of 81-99%.The composition of dissociated methanol gas is: hydrogen H
261-70%, carbon monoxide CO30-17%, methyl alcohol CH
3OH3%, water H
2O2-3% and other hydrocarbon inflammable gas.The characteristic of dissociated methanol gas is that (1) calorific value is higher by 20% than methyl alcohol; (2) velocity of combustion is fast, lean-burn is good, and the ignition energy that needs is little; (3) octane value height.Just because of the excellent specific property of cracking gas, can utilize it to realize the lean combustion of motor under middle-low load working condition.Its detailed process is: when dissociated methanol gas enters in the suction tude by reactor, middle necessary through mixer.It in mixer at first with air mixing, become dissociated methanol gas-air Mixture.Then again under closure 31 control (seeing accompanying drawing 2) enter in the suction tude.Regulate by the amount of 31 pairs of dissociated methanol gas-air of closure like this.Can change the degree of vacuum in the Carburetor 23 on the one hand, thereby change the air fuel ratio of Carburetor, the steam oil ratio (SOR) oil consumption that enters in the cylinder is reduced; Pass through Carburetor 23 owing to enter the interior dissociated methanol gas-air of suction tude on the other hand, thereby avoided the fluid resistance of carburetor throat portion.The air quantity that enters in the cylinder is increased, favourable to the improvement of power character.Therefore owing to regulate for the amount of dissociated methanol gas, make the gasoline-air-dissociated methanol gas that enters in the cylinder become a kind of thinner inflammable mixture by mixer.Utilize the lean burn characteristics of dissociated methanol gas at last, fully burn, thereby reach purpose of energy saving.
Secondly in the double fuel component of present technique, as the raw material of cracking hydrogen production, can also be with thick methyl alcohol, slightly methyl alcohol water mixing, ethanol, ethanol water mixing and fusel etc. except that methyl alcohol.Their cracking technology, mechanism principle, usability etc. are basic identical with dissociated methanol gas.
