Description
ANORDNING VED FORBRENNINGSMOTOR SOM ER TILORDNET EN LINEÆRFORSKYVBAR INDUKSJONSSPOLE COMBUSTION ENGINE DEVICE ASSOCIATED WITH A LINEAR DISPLACEABLE INDUCTION COIL
Denne oppfinnelse vedrører en forbrenningsmotor som er tilordnet en lineærforskyvbar induksjonsspole. Nærmere bestemt dreier det seg om en forbrenningsmotor som omfatter et stempel og en stempelsylinder samt nødvendige hjelpesystem av i og for seg kjent utførelse. Stempelet er via stempelstangen og en vippearm koplet til en lineærforskyvbar induksjonsspole som samvirker med en fastmontert permanentmagnet, og som derved er innrettet til å kunne produsere elektrisk energi når stempelet forskyves i stempelsylinderen. This invention relates to an internal combustion engine which is assigned to a linearly displaceable induction coil. More specifically, it concerns an internal combustion engine comprising a piston and a piston cylinder as well as the necessary auxiliary system of a known design per se. Via the piston rod and a rocker arm, the piston is connected to a linearly displaceable induction coil which cooperates with a fixed permanent magnet, and which is thereby arranged to be able to produce electrical energy when the piston is displaced in the piston cylinder.
Otto-motorer omfatter et stempel som via en stempelstang og Otto engines comprise a piston which via a piston rod and
en veivaksling er koplet til et svinghjul. Ved forbrenningsmotorer som baserer seg på dette prinsipp, og hvor produsert energi tas ut via veivakslingen, befinner veivakslingen seg nær sitt øvre dødpunkt når forbrenningstrykket over stempelet er høyest. Dette uheldige forhold bevirker at dreiemomentet som virker på veivakslingen under forbrenningens første del, blir relativt beskjedent. a crankshaft is connected to a flywheel. In combustion engines that are based on this principle, and where produced energy is taken out via the crankshaft, the crankshaft is close to its top dead center when the combustion pressure above the piston is highest. This unfortunate condition causes the torque acting on the crankshaft during the first part of the combustion to be relatively modest.
Andre mekaniske kraftoverføringsprinsipper har også vært forsøkt, men da forbrenningsmotorer generelt, og i kjøretøyer spesielt, avgir kraft ved sterkt varierende turtall og belastning, så har det allikevel resultert i en lavere total virkningsgrad enn den teoretisk oppnåelige. Other mechanical power transmission principles have also been tried, but as internal combustion engines in general, and in vehicles in particular, emit power at greatly varying speed and load, this has nevertheless resulted in a lower total efficiency than the theoretically achievable one.
Dette, sammen med andre forhold, bidrar til at en forbrenningsmotor av denne art oppviser en relativt beskjeden virkningsgrad. Oppfinnelsen har til formål å avhjelpe eller redusere i det minste én av ulempene ved kjent teknikk. This, together with other factors, contributes to an internal combustion engine of this type showing a relatively modest degree of efficiency. The purpose of the invention is to remedy or reduce at least one of the disadvantages of known technology.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som The purpose is achieved according to the invention by the features which
er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. is specified in the description below and in the subsequent patent claims.
En forbrenningsmotor i overenstemmelse med oppfinnelsen omfatter et stempel og en stempelsylinder samt nødvendige hjelpesystem av i og for seg kjent utførelse, og kjenne-tegnes ved at stempelet via stempelstangen og en vippearm er koplet til en lineærforskyvbar induksjonsspole som samvirker med en eller flere fastmonterte permanentmagneter, An internal combustion engine in accordance with the invention comprises a piston and a piston cylinder as well as the necessary auxiliary system of a known design in and of itself, and is characterized by the fact that the piston is connected via the piston rod and a rocker arm to a linearly displaceable induction coil which interacts with one or more permanently mounted permanent magnets,
og som derved er innrettet til å produsere elektrisk energi når stempelet forskyves i stempelsylinderen. and which is thereby arranged to produce electrical energy when the piston is displaced in the piston cylinder.
Permanentmagnet-enheten, som kan utgjøres av et antall stav-eller radial-magneter, er fastmontert til forbrenningsmotoren ved vippearmens induksjonsspole. The permanent magnet unit, which can be made up of a number of rod or radial magnets, is fixed to the internal combustion engine at the rocker arm's induction coil.
Det har vist seg at såkalte Neodym-magneter er velegnet for dette formålet. It has been shown that so-called Neodymium magnets are suitable for this purpose.
Induksjonsspolen er formet slik at den omkranser en permanentmagnet under hele stempelslaget. Den genererte energi kan da hentes ut fra spolen som vekselstrøm med en frekvens tilsvarende stempelfrekvensen. The induction coil is shaped so that it surrounds a permanent magnet during the entire piston stroke. The generated energy can then be extracted from the coil as alternating current with a frequency corresponding to the piston frequency.
Motoren vil kunne produsere strøm under alle stempelets takter. For å opprettholde en jevn stempelfrekvens er stempelet via stempelstangen og vippearmen koplet til et ubelastet svinghjul. Flere stempeler kan på i og for seg kjent måte være koplet til en felles vippearm. The engine will be able to produce electricity during all strokes of the piston. To maintain a uniform piston frequency, the piston is connected via the piston rod and rocker arm to an unloaded flywheel. Several pistons can be connected to a common rocker arm in a manner known per se.
Permanentmagnetens fester består av varmeisolerende materiale, da Neodym-magneters effekt avtar betydelig ved en forholdsvis lav øvre temperatur-terskel. The permanent magnet's fasteners consist of heat-insulating material, as Neodymium magnets' effect decreases significantly at a relatively low upper temperature threshold.
Tidligere løsninger med å plassere permanentmagneter i selve stempelet påvirkes av denne temperatur-faktor, og resulterer i en begrensning av energi-utbyttet. Previous solutions of placing permanent magnets in the piston itself are affected by this temperature factor, and result in a limitation of the energy yield.
Det er dessuten av avgjørende betydning å la induksjonsspolene være den bevegelige part i induksjons-prosessen, da disse vil ha en betydelig mindre vekt enn permanentmagnetene. Tidligere forsøk med å feste magneter til stempel og stempelstang har ikke vært vellykket, på grunn av magnetenes forholdsvis høye spesifikke vekt. Jo større vekt, jo mer energi kreves for både å akselerere og retardere magnetene, It is also of crucial importance to let the induction coils be the moving part in the induction process, as these will have a significantly smaller weight than the permanent magnets. Previous attempts to attach magnets to the piston and piston rod have not been successful, due to the relatively high specific weight of the magnets. The greater the weight, the more energy is required to both accelerate and decelerate the magnets,
og kraftutbyttet blir følgelig redusert. and the power output is consequently reduced.
I tidligere kjente publikasjoner innen fagområdet med elektrisk kraftuttak finnes idéer med å tilkople en mekanisk fjæranordning eller et elektromagnetisk system for å kunne opprettholde en stabil og repeterende mekanisk funksjon. In previously known publications in the field of electric power take-off there are ideas of connecting a mechanical spring device or an electromagnetic system in order to be able to maintain a stable and repetitive mechanical function.
I publikasjon US2002/0139323A1 indikeres valgfritt alternativ av bruk av komprimerbar spiralfjær, eller elektromagnetisk kraft som støtte til stempelstangen. Begge alternativene er imidlertid energikrevende, og er en medvirkende årsak til redusert virkningsgrad. I tillegg indikeres at induksjonsspolen kan være stasjonær, og magneten bevegelig. In publication US2002/0139323A1, an optional alternative of using a compressible coil spring, or electromagnetic force as support for the piston rod is indicated. However, both options are energy-intensive, and are a contributing factor to reduced efficiency. In addition, it is indicated that the induction coil can be stationary, and the magnet movable.
Dette vil imidlertid være ødeleggende for virkningsgraden. Etter som magnetene her også er en del av selve motorhuset, så vil motor-temperaturen kunne redusere bruk av neodym-magneter. I publikasjon GB2219671A utgjør magneten den bevegelige komponent i induksjons-prosessen, og dette vil som nevnt være negativt for energi-utbyttet. However, this will be detrimental to the efficiency. As the magnets here are also part of the motor housing itself, the motor temperature will be able to reduce the use of neodymium magnets. In publication GB2219671A, the magnet is the moving component in the induction process, and this will, as mentioned, be negative for the energy yield.
I publikasjonene DE19943993A1, JP57044732, GB2358845A og WO2006/108297A1, utgjør også her magneten den bevegelige komponent i induksjons-prosessen, og sammen med høy temperatur i magnet-området vil dette være begrensende faktorer for virkningsgraden. In the publications DE19943993A1, JP57044732, GB2358845A and WO2006/108297A1, here too the magnet is the moving component in the induction process, and together with high temperature in the magnet area, these will be limiting factors for the efficiency.
I publikasjon DE20305046 er magneten festet til selve veivakselen, og induserer strøm i en fastmontert spole. Arbeidsprinsippet er dermed det samme som i en tradisjonell motor, med kraftuttaket via en roterende veivaksel. Det betyr at når forbrenningstrykket over stempelet er høyest, så befinner veivakslingen seg nær sitt øvre dødpunkt. Dette uheldige forhold bevirker at dreiemomentet som virker på veivakslingen under forbrenningens første del blir relativt beskjedent. In publication DE20305046, the magnet is attached to the crankshaft itself, and induces current in a fixed coil. The working principle is thus the same as in a traditional engine, with the power output via a rotating crankshaft. This means that when the combustion pressure above the piston is highest, the crankshaft is close to its top dead center. This unfortunate condition causes the torque acting on the crankshaft during the first part of the combustion to be relatively modest.
En forbrenningsmotor ifølge oppfinnelsen tilveiebringer en relativt enkel og effektiv måte for å omforme mekanisk energi til elektrisk energi. Motoren vil med fordel kunne anvendes i kjøretøy hvor hele drivverket vil kunne erstattes av en elektromotor i hvert drivhjul. Motoren vil kunne arbeide ved en frekvens som gir best mulig kombinasjon av effekt, virkningsgrad og relativt små utslipp. An internal combustion engine according to the invention provides a relatively simple and efficient way to transform mechanical energy into electrical energy. The engine can be advantageously used in vehicles where the entire drivetrain can be replaced by an electric motor in each drive wheel. The engine will be able to work at a frequency that provides the best possible combination of power, efficiency and relatively low emissions.
Ved bruk av Hydrogen som brennstoff vil de forurensende utslippene fra bensin, diesel og LNG kunne elimineres. By using Hydrogen as a fuel, the polluting emissions from petrol, diesel and LNG can be eliminated.
I det etterfølgende avsnitt beskrives et ikke-begrensende eksempel på en foretrukket utførelsesform som er anskueliggjort på medfølgende tegninger, hvor: In the following section, a non-limiting example of a preferred embodiment is described which is illustrated in the accompanying drawings, where:

Fig. 1 shows schematically in section a 2-cylinder internal combustion engine according to the invention, where one piston is located at its top dead center, and the other piston at its bottom dead center; and Fig. 2 schematically shows the same as in fig. 1, but here the pistons have moved half a beat in the cylinder; and Fig. 3 schematically shows the same as in fig. 1 and 2, but here 4 cylinders are connected to a common rocker arm.
