Description

KRMILNA NAPRAVA ZA ELEKTRONSKO KRMILJENJE BENCINSKEGA MOTORJA Z NOTRANJIM IZGOREVANJEM ZA UPORABO GORLJIVIH PLINOVCONTROLLER FOR ELECTRONIC CONTROL OF A GASOLINE ENGINE FOR THE USE OF FUEL GASES

Predmet izuma [001] Predmet izuma je krmilna naprava elektronsko krmiljenega bencinskega motorja z notranjim izgorevanjem, ki vodi vbrizg gorljivega plina za nadomeščanje primarnega goriva.The subject of the invention The object of the invention is a control device of an electronically controlled internal combustion gasoline engine, which directs the injection of combustible gas to replace the primary fuel.

Tehnični problem [002] Tehnični problem, ki ga rešuje izum je, kako zasnovati tako krmilno napravo elektronsko krmiljenega bencinskega motorja z notranjim izgorevanjem, ki bo pri predelavi motorja na gorljivi plin zagotavljal polnjenje valjev z ustrezno količino plina glede na vsakokratne pogoje delovanja motoqa in zahteve voznika, tako da ne spreminja temeljnih nastavitev delovanja motorja, zlasti tistih, ki so pri elektronsko krmiljenih motorjih določene z digitalno karto (maping), pri čemer naj bi bila taka naprava tehnično in cenovno ugodna tudi pri prireditvi za manjše serije posameznega tipa vozil, celo za prireditev v samo eno vozilo nekega tipa. Seveda se pričakuje, da naj taka naprava po izumu naj ne bi omejevala uporabe bencina kot goriva, pri čemer naj bi bil preklop uporabe bencina ali gorljivega plina za uporabnika enostaven, kot je to znano pri obstoječih tovrstnih napravah.Technical Problem [002] The technical problem to be solved by the invention is how to design such a control unit of an electronically controlled internal combustion gasoline engine that will, in the conversion of the combustible gas engine, provide the cylinders with the proper amount of gas according to the respective motoq operating conditions and requirements driver, so that it does not change the basic settings of the engine, especially those that are electronically controlled by digital mapping (mapping), with such a device being technically and cost-effective even for smaller series of individual vehicle types, even to fit into just one vehicle of some type. Of course, it is expected that such a device according to the invention should not limit the use of gasoline as a fuel, and switching the use of gasoline or combustible gas to the user is as easy as is known with existing such devices.

Znano stanje tehnikeThe prior art

KN-01-2011 - G-1 [003] Zaradi različne energetske vrednosti bencina in gorljivega plina je potrebno pri predelavi motorja na gorljivi plin pri vsakem polnjenju valja s plinsko zmesjo spremeniti količino plina, da se čim bolj približa energetski vrednosti bencina. Pri zasnovi tovrstne krmilne naprave je potrebno upoštevati tudi razliko v hitrosti gorenja različnih goriv, razliko v izpodrivni vrednosti različnih goriv in razliko v odzivni hitrosti odpiranja in zapiranja dozirnih ventilov, ki odpirajo in zapirajo dovod posameznega goriva. Prav tako je potrebno upoštevati delovanje regulatorja tlaka in nastavitev višine tlaka.KN-01-2011 - G-1 [003] Due to the different energy values of gasoline and combustible gas, it is necessary to change the amount of gas at each gas cylinder refueling in order to approximate the energy value of gasoline when refueling with a gas mixture. The design of such a control device must also take into account the difference in the burning rate of different fuels, the difference in the displacement value of different fuels, and the difference in the response rate of opening and closing metering valves that open and close the inlet of an individual fuel. The operation of the pressure regulator and the setting of the pressure altitude must also be taken into account.

[004] Dosedanje tovrstne naprave so izvedene tako, da v celoti zamenjujejo originalno krmilno naprav z upoštevanjem značilnosti plina. Problem teh naprav je, da jih je potrebno prirediti v smislu priprave digitalne karte (maping) in glede na tovarniško predvidena tipala za vsak tip vozila posebej, kar je zamudno in drago. Za manjše serije posameznega tipa vozil, postane taka naprava tržno nekonkurenčna.Such devices have been designed to completely replace the original control devices, taking into account the characteristics of the gas. The problem with these devices is that they need to be customized in terms of digital mapping and factory-fitted sensors for each vehicle type, which is time-consuming and expensive. For smaller series of each type of vehicle, such a device becomes commercially non-competitive.

[005] Nadalje poznamo drugi tip teh krmilnih naprav, ki prevzemajo od originalne naprave sprejem vrednosti na različnih tipalih na motorju, ki jih nova digitalna karta v dodatni krmilni napravi upošteva in generira ukazne parametre, kot so začetek in čas odprtja šob za vbrizg plina v sesalne kolektorje in trenutek vžiga. Taka zasnova tovrstne krmilne naprave je sicer cenejša od zgoraj navedene, vendar še zmeraj ostane problem prireditve take naprave za manjše število istovrstnih vozil zaradi cene. Njena pomanjkljivost je v tem, da se v njej podatki, ki jih generira originalna krmilna naprava, obdelajo glede na njeno digitalno karto (maping) in se kot rezultat tvorijo krmilni ukazi. Za ta proces je potreben en cikel v njenem mikroprocesorju. V sled tega je prisotna vedno tudi sistemska napaka, ki se kaže pri hitrih spremembah režima delovanja motorja, t.j. pri pospeševanju ali vožnji v klanec. Izkoristek motorja v teh stanjih se zniža.[005] We further know the second type of control devices, which assume from the original device the reception of values on various engine sensors, which the new digital card in the additional control device takes into account and generates command parameters, such as the start and opening time of the gas injection nozzles in intake manifolds and ignition timing. Such a design of such a steering device is cheaper than the above, but it still remains a problem to make such a device for a smaller number of vehicles of the same type because of the price. Its disadvantage is that the data generated by the original control device is processed according to its digital map (mapping) and as a result control commands are formed. This process requires one cycle in its microprocessor. As a consequence, there is always a system error, which is manifested by rapid changes in the mode of operation of the engine, i.e. when accelerating or uphill. The engine efficiency in these conditions is reduced.

KN-01-2011 -G-1 [006] Zgoraj opisane slabosti je rešila naprava po patentnem zahtevku P200800186, ki pa ima pomanjkljivost pri uporabi na določenih plinih na določenih območjih delovanja v iskanju idealnega izgorevanja za doseganje optimalnih izpušnih plinov. Z uporabo fiksne korekcijske konstante lahko motor v določenih območjih delovanja prehaja izven idealnega izgorevanja kar povzroča neoptimalno izgorevanje in posledično izpuh.KN-01-2011 -G-1 [006] The disadvantages described above have been resolved by the apparatus of claim P200800186, which however has the disadvantage of being used on specific gases in certain operating areas in search of ideal combustion to achieve optimal exhaust gases. By using a fixed correction constant, the engine can go beyond ideal combustion in certain operating areas, resulting in suboptimal combustion and, consequently, exhaust.

[007] Glede na dejstvo, da naj bi predelave vozil na gorljivi plin izvajali na že kupljenih vozilih v smislu druge vgradnje in da naj bi to izvajali pooblaščeni servisi, je pričakovati, da naj bi imel vsak servis možnost hitro predelati vozila mnogih znamk, ki se nahajajo v njegovem tržnem območju za tržno sprejemljivo ceno in na logistično in tehnično enostaven način in posledično tudi zagotoviti optimalno delovanje vozila z optimalnim in najnižjim škodljivim izpustom.[007] In view of the fact that the conversion of combustible gas vehicles is to be carried out on vehicles already purchased in terms of second installation and that it is to be performed by authorized repairers, it is to be expected that each service facility should be able to quickly remodel vehicles of many brands which are located in its market area for a reasonably priced market place and in a logistically and technically simple manner and consequently also ensure the optimum performance of the vehicle with the optimum and lowest harmful discharge.

Rešitev tehničnega problema [008] Opisani tehnični problem je rešen z napravo po izumu, katere bistvena značilnost je v tem, da vključuje originalno krmilno enoto z digitalno karto (maping) in novo dopolnilno krmilno enoto, ki krmilni podatek za začetek in trajanje odprtja elektronske šobe za dovod plina, in sicer tako, da spreminja s korekcijsko gibljivo konstanto, ki je odvisna od razlike v kalorični vrednosti gorljivega plina od primarnega goriva, razlike v hitrosti gorenja, izpodrivni vrednosti obeh goriv in razlike v hitrosti odpiranja in zapiranja dozirnih ventilov za posamezno gorivo, začetek odpiranja pa ostane nespremenjen, kot ga določa originalna krmilna enota. To velja za vsak sesalni takt. Korekcijsko konstanto se določi na osnovi meritev naštetih razlik in testiranj na različnih modelih vozil. Korigiranje korekcijske konstante z gibljivim delom pa se izvede za posamezne tipe vozil posebej glede na izvajanje meritev izpuha in delovanja motorja. Ostali krmilni parametri ostanejo nespremenjeni, tudi instalacija za te parametre ostane originalna. Ker ne posegamo v digitalno karto originalne krmilne naprave, jeSolution to a Technical Problem [008] The technical problem described is solved by a device according to the invention, the essential feature of which is that it includes an original digital mapping control unit and a new complementary control unit that controls the start and duration of the electronic nozzle opening for supplying gas by varying with a correction moving constant that depends on the difference in the calorific value of the combustible gas from the primary fuel, the difference in burning rate, the displacement value of the two fuels, and the difference in the rate of opening and closing of the metering valves for each fuel and the start of the opening remains unchanged as specified by the original control unit. This applies to every suction stroke. The correction constant is determined on the basis of measurements of the listed differences and tests on different models of vehicles. However, the correction constant with the moving part is performed for individual vehicle types separately with respect to the measurement of the exhaust and the engine performance. Other control parameters remain unchanged, and the installation for these parameters remains original. As we do not interfere with the digital map of the original control device, it is

KN-01-2011 -G-1 sploh ni potrebno poznati. To je pomembno zlasti pri redkejših vozilih na posameznem tržnem območju. Ker je takt mikroprocesorjev bistveno višji od sesalnih taktov bencinskih motorjev z notranjim izgorevanjem, kar je odvisno od števila vrtljajev motorja, dovoljujeta mikroprocesoija originalne krmilne naprave in dopolnilne krmilne enote korekcijo signala za odpiranje Šobe za plin vedno v istem sesalnem ciklu motorja z notranjim izgorevanjem. S tem je zagotovljeno, da je vsak signal za odpiranje šobe za plin, ki je enolično določen na osnovi digitalne karte in podatkov tipal, pravilno korigiran s korekcijsko konstanto v skladu z vsakokratnimi podatki tipal in temu ustrezni točki na digitalni karti krmiljenja. To je možno zato, ker je vnaprej predvidena gibljiva korekcijska konstanta za vsak tip motorjev posebej v tem smislu, da vsakokratna energetska vrednost vbrizganega plina kar se najbolj ustreza energetski vrednosti vbrizganega primarnega goriva.KN-01-2011 -G-1 need not be known at all. This is especially important for rarer vehicles in a particular market area. Since the microprocessor clock is significantly higher than the intake stroke of the internal combustion engine, depending on the engine speed, the microprocessor of the original control unit and the supplementary control unit allow the correction of the signal to open the Nozzle for gas always in the same intake cycle of the internal combustion engine. This ensures that each gas nozzle opening signal, which is uniquely determined on the basis of the digital map and sensor data, is correctly corrected by a correction constant in accordance with the respective sensor data and the corresponding point on the digital control map. This is possible because there is a predetermined moving correction constant for each type of engine in the sense that the respective energy value of the injected gas is as close as possible to the energy value of the injected primary fuel.

[009] Podrobneje bo izum pojasnjen v nadaljevanju z opisom izvedbenega primera in priložene risbe, na kateri kaže sl. 1 shematsko vezalno shemo naprave po izumu, prigrajene k bencinskemu motorju z notranjim izgorevanjem.[009] The invention will be explained in more detail below with a description of an embodiment and the accompanying drawing, in which FIG. 1 is a schematic wiring diagram of an apparatus of the invention attached to an internal combustion gasoline engine.

[0010] Krmilna naprava 1 elektronsko krmiljenega bencinskega motorja 2 z notranjim izgorevanjem, ki je predelan za delovanje na gorljivi plin, je zasnovana tako, da v popolnosti vključuje originalno krmilno napravo 3 motorja 2 s tem, da ostanejo nespremenjena tudi vsa originalna tipala 4 , ki so priključena nanjo ter dodatno krmilno enoto 5, ki krmili na osnovi podatkov osnovne krmilne enote 3 plinske injektorje 6 tako, da v vsakem sesalnem taktu motorja 2 zagotavlja polnjenje vsakotaktnega valja s tako količino plina, katere energetska vrednost je enaka energetski vrednosti tiste količine bencina, ki jo določi originalna krmilna naprava 3 za isti sesalni takt.[0010] The control unit 1 of the electronically controlled internal combustion gasoline engine 2, which is processed to operate on combustible gas, is designed to fully incorporate the original control device 3 of the engine 2, while maintaining all the original sensors 4, connected thereto and an additional control unit 5 which controls, on the basis of the data of the basic control unit 3, gas injectors 6 in such a way that at each suction stroke of the engine 2 it provides a filling of each stroke cylinder with a quantity of gas whose energy value is equal to the energy value of that quantity of gasoline specified by the original control unit 3 for the same suction stroke.

KN-01-2011 -G-1 [0011] Originalna krmilna naprava 3 je tudi sestavni del krmilne naprave 1 predvidena za enako krmiljenje vžiga, tako da pošilja na vžigalne svečke 7 visokonapetostni tok v istem trenutku glede na kot glavne gredi, kot je predvideno po njeni originalni karti (mappingu).KN-01-2011 -G-1 [0011] The original control unit 3 is also an integral part of control unit 1 intended for the same ignition control by sending high voltage current to the spark plugs 7 at the same instant relative to the main shaft angle as intended according to her original map (mapping).

[0012] Prav tako tvori originalna krmilna naprava 3 sestavni del krmilne naprave 1 signal za začetek trajanja odprtja injektoijev 6 za vbrizg plina v sesalni kolektor 8 motorja 2. Ta signal je določen na osnovi digitalne karte (mappinga) v napravi 3 in podatkov, ki jih posredujejo tipala 4 na motorju 2 oziroma na sklopih, ki so nanj priključeni. Ta signal je voden po vodniku 9 v dodatno krmilno enoto 5. V istem mikroprocesorskem koraku originalne krmilne naprave 3 podaljša dodatna krmilna enota 5 s korekcijsko časovno konstanto (v določenih primerih za določeno območje delovanja korigirano v lastni mapi) čas odprtja injektorjev 6 za dovod plina v valje motorja 1, medtem ko ostane čas začetka odprtja injektorjev 6 isti, kot gaje določila originalna krmilna enota 2.[0012] The original control device 3 also forms an integral component of the control device 1 to initiate the duration of the injection opening 6 for gas injection into the intake manifold 8 of the engine 2. This signal is determined on the basis of a digital map (mapping) in the device 3 and data that they are transmitted by the sensors 4 on the motor 2 or the assemblies connected to it. This signal is guided through conductor 9 to additional control unit 5. In the same microprocessor step of the original control unit 3, an additional control unit 5 is extended with a correction time constant (in certain cases for a specific operating area corrected in its own folder) the time of opening of the injectors 6 for gas supply into the cylinders of the engine 1, while the start time of the injector opening 6 remains the same as specified by the original control unit 2.

[0013] Korekcijska konstanta je določena na osnovi razlik v uporabljenih gorivih in hitrosti odpiranja in zapiranja injektorjev, kar se lahko določi z meritvami ali pa poizkusno in se to konstanto določi za uporabljene injektorje (ventile) in uporabljen gorljivi plin. Korigiranje korekcijske konstante se določi z testno vožnjo in opazovanjem delovanja preko OBD ali z uporabo dynometra in se tako po potrebi ob uporabi določenih gorljivih plinov korigira konstanto v določenih območjih delovanja motorja v katerih bi fiksna korekcijska konstanta pripeljala delovanje motorja izven območja optimalnega izgorevanja.[0013] The correction constant is determined on the basis of differences in the fuels used and the speed of opening and closing the injectors, which can be determined by measurements or experimentally, and this constant can be determined for the injectors (valves) used and the combustible gas used. Correction of the correction constant is determined by test driving and observing operation through the OBD or by using a dynometer to correct, where necessary, using certain combustible gases a constant in certain areas of engine operation in which a fixed correction constant would drive the engine out of the optimum combustion zone.

[0014] Ker imajo bencin in različni plini, ki jih lahko uporabimo kot gorivo različne specifične energijske vrednosti, mora biti volumen izbranega goriva tak, da ostane nespremenjena energetska vrednost količine goriva za en sesalni takt enega valja ista, kot jo določa originalna krmilna naprava 3. Ker je čas zaprtja plinskega injektorja 6 določen za bencinski injektor 6a, je predvideno, da[0014] Since gasoline and different gases that can be used as fuel have different specific energy values, the volume of the selected fuel must be such that the unchanged energy value of the amount of fuel for one intake stroke of one cylinder is the same as that specified by the original control device 3 Since the closing time of the gas injector 6 is fixed for the petrol injector 6a, it is provided that

KN-01-2011 -G-1 nastavimo energetski ekvivalent plinske količine z določitvijo tlaka plina v injektorju. To dosežemo tako, da uporabimo tlačni regulator na uparjalniku 10 plina, ki je privzet kot znano stanje tehnike in se nahaja na tržišču v več izvedbah.KN-01-2011 -G-1 we set the energy equivalent of the gas quantity by determining the gas pressure in the injector. This is achieved by using a pressure regulator on the gas evaporator 10, which is the default state of the art and is commercially available in several embodiments.

[0015] S tako dopolnilno krmilno enoto 5 po izumu, se bistveno zmanjša cena vgradnje celotne naprave za pogon na utekočinjen plin (tlačna posoda za utekočinjen plin, cevne instalacije, ventili, uparjalnik plina idr).With such an additional control unit 5 according to the invention, the cost of installation of the entire liquefied gas propulsion device (liquefied gas pressure vessel, piping, valves, gas evaporator, etc.) is significantly reduced.

[0016] Predviden je tudi enostaven preklop uporabe plina oziroma bencina kot goriva z električnim stikalom, ki omogoča to spremembo tudi med vožnjo.[0016] Also provided is a simple switch between the use of gas or petrol as a fuel with an electric switch, which allows this change even while driving.

[0017] Pri uporabi bencina kot gorivo je uporabljena samo originalna oprema vozila, kot je poznano tudi že pri drugih tovrstnih napravah.[0017] When using gasoline as a fuel, only the original equipment of the vehicle is used, as is known in other such devices.
