The test achievement is the testing data of implementing in Korea S state-run Pusan mechanical skill institute of university on the experimental result.
Experiment content is the starting of analyzing excessive service performance, acceleration, deceleration and pressure characteristic and exhaust ejecta characteristic, and about the torque on standard state, the sales control energy, thermo-efficiency, noise properties, vibrant characteristic.On the test-results graphic representation, methanol reformulated fuel alternative to gasoline numeral of the present invention or picture are represented with MRF (Methanol Reformulated-Fuel) below.
The automobile that uses in the trial run and run test in the middle of the test is Hyundai automobile Atoz (800cc) below, Verna (1500cc), Trajet (2700cc), Sonata (2000cc), Grandeur (3000cc), Equus (3500cc) and Daewoo Motor Tico (800cc), Prince (1800) and U.S. Cadillac (4000cc), Chrysler (4500cc) and German BMW (4000cc).
Or it is the LEGANGA of Hyunju (1800cc) that the state-run Pusan of Korea S university mechanical skill is studied employed experiment automobile, and Korea S's National Institute for Environmental Studies is that the automobile that the exhaust measuring test is used is the SONATAIII of Hyundai and the EF SONATA2.0 of Hyundai
Fig. 1 is for observing the test that the starting characteristics are represented the over-running characteristics.Can know at Fig. 1 and to represent higher running of an engine number about 3 seconds at fuel initial stage of the present invention when starting, but between the injection period of the fuel of our invention during the fuel injection but much shorter.
This means that with general steam oil ratio (SOR) our the abundant fuel of invention of oxygen content has carried out combustion processes very actively.The characteristics that this characteristics let us guesses the exhaust thing are better, or these characteristics had influence on east the initial stage engine the running number become height.
Pressure characteristic during Fig. 2 represents after the starting during 20 cycles (Cycle), two curves of Fig. 2 the inside all have similar pressure variation curve, but the high 5bar of the pressure ratio gasoline of our fuel on the pressure variation curve of period 1, on average, the pressure ratio gasoline of our invention product bigger, this is the result that the height running number because of one of starting characteristics engine causes.
Fig. 3 to compare the pressure variation curve in a cycle (CYCLE) after the aptitude to burn starting and is the pressure variation curve of 100 times stable CYCLE of engine in order to check.
Pressure variation curve (1 in the period 1
StCycle) last two kinds of fuel are represented similar combustioncharacteristics, and on pressure variation curve, the high 5bar of pressure of the fuel of our invention is at 100 pressure variation curves (100
ThCycle) last two kinds of fuel all have similar characteristics during the initiation combustion, during the after burning we the invention fuel burn at the pressure higher than gasoline, this just mean with steam oil ratio (SOR) get up octane value and combustible aspect we the invention fuel more outstanding.And can expect fuel ratio gasoline of the present invention and control energy, thermo-efficiency and unburn exhaust ejecta the time takes place less for exert oneself torque and burning.
Excess air ratio that draws with wide area oxygen perceptron after Fig. 4-1 and Fig. 4-2 represents respectively to start and oxygen sensitive signal voltage be curve over time.According to our fuel of invention of Fig. 4 variation taking place in 20 seconds, has really carried out the feedback control process in 40 seconds, but gasoline carry variation take place for 30 seconds, just carried out the feedback control process in 60 seconds, become the stabilization of excess air ratio.
This is the result that the height running number of the engine that takes place in starting period because of the fuel of our invention causes.Because than stabilization of gasoline change fast 20 seconds, so the exhaust ejecta of the fuel that we invent in the time of can reckoning with starting still less, the invention product that the result can predict us are that just the reaction initial stage does not have to change more than 250 degree Celsius because of the oxygen perceptron than the more outstanding electric power of measuring with wide area oxygen perceptron that rises of gasoline.
Along with the temperature rising of exhaust ejecta, variation has taken place in gasoline in 20 seconds, really carried out feedback (feedback) control process in 60 seconds.The variation of an electric power has taken place in the fuel of our invention in 20 seconds, has just carried out the process of feedback (feedback) in 40 seconds, and the variation that plays electric power is just the same with excess air ratio.
Fig. 5 represents to start the characteristics of back to the exhaust ejecta between 120 seconds.According to Fig. 5, the fuel ratio gasoline exhaust ejecta much less of our invention.Carbon monoxide element (CO) in the exhaust, hydrocarbon (HC) are that the incomplete combustion by fuel takes place.And nitronic acid thing (Nox) is that an oxide compound of heat reacts later.So we seldom discharge carbon monoxide element (CO) by the fuel ratio gasoline of invention, the height of engine running number when the reason that hydrocarbon (HC) comes is starting, in the after burning of the high pressure of 100 pressure variation curves, control in the excess air ratio feedback in fast 20 seconds (feedback).Oxynitride (NOx) reason that becomes is variation along with feedback (feedback) control, and excess air ratio has also changed.
Fig. 6 is as the criterion relatively to get off with gasoline from the exhaust ejecta amount that starting is come out period to 120 seconds.
The exhaust ejecta amount that takes place in the time of can knowing starting by Fig. 6, the exhaust ejecta of the fuel that we invent is than the much less of gasoline.
Be exactly, hydrocarbon (HC), our the fuel ratio gasoline of invention has taken place 51.2% less, carbon monoxide element (CO), our the fuel ratio gasoline of invention has taken place 72.9% less, and oxynitride (NOX) has taken place 58.9% less.Therefore our fuel peace and quiet environment-friendly fuel more outstanding aspect environmental protection than gasoline.
Fig. 7 is to be the curve that picture is represented with various patterns aspect accelerating performance.Fig. 7 represents that (a) fan-shaped acceleration (Linear acceleration), (b) delay quickening (Delayacceleration), (c) progressively quicken (Intensity acceleration), (d) eliminate acceleration (Decayacceleration) and reflect that carefully the slow acceleration of the characteristic of fuel reflects the slow acceleration of the characteristic of fuel carefully, as the responsiveness that quickens the moving revolution of pattern test engine.
Fig. 8-1 and Fig. 8 the-the 2nd, and superincumbent various acceleration patterns are the responsiveness of expression running of an engine number down, and just the running of an engine number is from 1, and 500rpm accelerates to 3, the accelerated test of 000rpm.
Can know that by Fig. 8 fuel that we invent represents with the similar engine responsiveness of gasoline.Therefore, aspect accelerating ability, the alternative fuel of our invention as for the existing fuel that uses, does not have assorted one problem.
Fig. 9-1 and Fig. 9 the-the 2nd, accelerated test: excess air ratio (fan-shaped acceleration 0.5 second and 3.0 seconds condition under).
Fig. 9-1 and Fig. 9 the-the 2nd, measures in the excess air ratio variation that fan-shaped acceleration pattern suddenly quickened 0.5 second and slow acceleration was showed in 3 seconds.
According to Fig. 9, during acceleration,, carried out the combustion processes of the dense state of fuel along with the instantaneous increase of fuel, the regulating and controlling air capacity of while with the feedback (feedback) of oxygen perceptron becomes stable status.At 0.5 second and 3 seconds, because of the fuel of our invention, than gasoline, the still stabilization procedures with low uncertainty of excess air ratio was quickly carried out, and took place so can reckon with that the exhaust ejecta lacks than gasoline.
Figure 10-1 and Figure 10-2 expression gasoline and fuel of the present invention are in the characteristic of the exhaust ejecta of anxious 0.5 second of quickening and the fan-shaped acceleration pattern of slow 3 seconds time of quickening.Appearance at two kinds of fuel of Figure 10-1 and Figure 10-2 the inside is similar, and the characteristic of Here it is two kinds of exhaust ejectas is similar.Strictly say nextly, the curve ratio gasoline of the fuel of our invention hang down a little, so can know a little less youngster of exhaust ejecta amount.
(HC) has very fast responsiveness because of hydrocarbon, so than carbon monoxide element (CO), oxynitride (Nox), changing time point faster appearance, especially oxynitride (Nox) needs the residence time under hot conditions, changes time point and slowly occurs.
Can not know that at Figure 10-1 and Figure 10-2 fuel along with our invention of acceleration has exhaust to send the big variation of one of thing carbon monoxide element (CO) amount.Particularly change in the severe city characteristics that the fuel of our invention is played very well at car speed, the characteristics of thing are sent in outstanding exhaust that Here it is.
Figure 11 represents gasoline and fuel of the present invention in order to understand acceleration and the deceleration characteristic on excessive service performance, quickens 0.5 second and slowly quickens engine rotation in 3 seconds and count process, the process of observing the stable of engine and exhaust ejecta characteristic maintenance in 45 seconds 3000rpm and 3000rpm that 1500rpm quickens to the 3000rpm position to the air door valve of 1500rpm moderating process anxious.Can see on Figure 11 anxious and quicken 0.5 second and slowly keep the engine rotation number the same on the boiled valve state of fuel ratio gasoline of the present invention (emitted dose of fuel is few) in the acceleration 3 seconds with gasoline, therefore the burning result of high pressure in the after burning of graphic representation 3 can expect the effect of exhaust ejecta and the torque of exerting oneself, sales control energy and thermo-efficiency.
The responsiveness curve of engine revolution when Figure 12 represents gasoline and fuel of the present invention acceleration alkali speed.Figure 12 represents fast the acceleration 0.5 second, the reactive aspect of the engine revolution when quickening 3 seconds late, and gasoline and our fuel of invention have same variation.Therefore this methanol fuel acts as a fuel aspect reactive at engine and can say not have assorted one problem.
When Figure 13-1,13-2,13-3,13-4,13-5,13-6 represent gasoline and fuel acceleration-deceleration of the present invention 0.5 second, 3 seconds riving conditions are the deflated gas of discharging down.
Figure 13-1,13-2,13-3,13-4,13-5,13-6 analyze, and the content of the exhaust emissions material of generation is similar with this fuel.But the waveform of this fuel than gasoline at the bottom of.The exhaust material that can say this fuel draining lacks than gasoline.
Figure 14 represents the data of noise test under gasoline and the fuel normal condition of the present invention.Noise be with the revolution of engine and combustion noise than row.Figure 14 represents to measure noise.The noise that the noise measuring device takes place according to engine revolution from the position finding of engine 1M distance.
Figure 14 represents that the noise that this fuel takes place lacks than gasoline.The noise of zero load 850rmp is less than about 2.2db, and the noise of sub-load 1500 and 2500rpm is less than about 1.2db, and the noise of sub-load 1500 and 2500rpm is less than about 1.2db.
Figure 15 represents gasoline and the testing data curve of fuel of the present invention about shaking.Figure 15 is in order to measure the vibrations that engine takes place, shock sensor is located at engine cylinder body top, measure the transposition difference that takes place because of engine revolution.
Figure 15 represents that the vibrations that this alternative fuel takes place lack than gasoline.And noise, vibrant characteristic is represented the ratio of combustion gasoline homogeneous of this fuel.
Figure 16 is in order to confirm the engine power characteristic to fuel, is that the measurement result of mensuration torque is more outstanding than gasoline at this power characteristic of fuel of all revolutions.
Figure 17-1 and 17-2 represent the consumption and the thermo-efficiency of the braking energy of gasoline and fuel of the present invention respectively.The consumption of braking energy is the economy of considering fuel, the energy that consumes for the merit that obtains 1KW/H.
The braking energy consumption rate gasoline of this fuel of Figure 17-1 expression is few.The meaning is that fuel is bigger than gasoline with the small amount of energy power.Figure 11 also confirmed this content.
Braking energy consumption and thermo-efficiency are inversely prroportional relationships.The thermal efficiency ratio gasoline of this fuel is good.
Figure 18 represents the cyclical swing rate of gasoline and fuel of the present invention.The working cycle change is a counting of judging the incendiary unhomogeneity, the words of fuel that flows to from the combustion chamber and air mixed trouble-free burning, there is not the working cycle change, can there be the vaporization heat of the fuel that provides to change in the burning actually, cause that (air: fuel) the incendiary heterogeneity takes place air-fuel ratio in change, because the inhomogenous pressure change counting of incendiary is called the working cycle rate of change.By above-mentioned Figure 18, can know that fuel ratio gasoline of the present invention is showing low numeral.Can know that by this point fuel combustion of the present invention fixes than gasoline.This point is safer because of authentication fuel ratio gasoline combustion of the present invention on top noise, the vibration test gets have been suspected.

The effect of invention
The primary condition that replaces fuel is that at first raw material is wanted fully, also has economy, security and can secularly supply.
To replacing the suitable reason of fuel to be; First methyl alcohol at normal temperature is liquid state, more manageable than hydrogen or Sweet natural gas, second is shorter therebetween than other replacement fuel exploitations because of tackling original technology, the 3rd molecular structure is the few oxygen compound of carbon content, carbon monoxide element (CO) and hydrocarbon (HC) are few during burning takes place, the 4th manufacturing technology owing to natural gas, coal or wood etc., abundant raw material, the 5th unit price cheaply has economy etc.Also have methyl alcohol because of the normal temperature liquid state to transport, storage etc. is manageable, inner cooling performance is bigger, burns on low temperature than gasoline, oxynitride (NOx) lacks than gasoline and takes place.
Therefore based on the methyl alcohol of the present invention of methyl alcohol change a social system fuel instead fuel have outstanding characteristic.
Also have methyl alcohol transformation of the way fuel of the present invention on original motor car engine or fuel system, not have structural changes directly to use, can use with gasoline.
And use methyl alcohol transformation of the way fuel of the present invention, lack harmful gas (carbon monoxide element: CO, hydrocarbon: HC, the oxynitride: NOx) of discharging than gasoline.Methyl alcohol transformation of the way fuel therefore of the present invention reduces the fuel of the close environment of topsoil, the peace and quiet fuel of inferior epoch of gasoline replacing.
