Doterajší stav technikyPrior art
Spaľovacie motora pracujú na 2-taktnom a 4-taktnom princípe a využívajú tlakovú energiu horúcich plynov v spaľovacom valci. Ďalšie využitie energie výfukových plynov je nežné v plynovej turbíne alebo vo výmenníku tepla. Takto získaná práca sa využíva na pohon zariadení na preplňovanie motorov.Internal combustion engines work on the 2-stroke and 4-stroke principle and use the pressure energy of hot gases in the combustion cylinder. Another use of exhaust energy is gentle in a gas turbine or heat exchanger. The work thus obtained is used to drive equipment for supercharging engines.
Pri výluku spalín zo spaľovacieho valca do atmosféry sa do atmosféry dostávajú škodlivé splodiny nedokonalého borenia CO a nespálené uhľovodíky, ako aj oxidy dusíka a hlavný produkt spaľovania CO·?, ktorý je považovaný za príčinu vytvárania skleníkového efektu a postupného otepľovania atmosféry. Tieto spaliny produkujú 4-taktné aj 2-taktné motory. Dvojtaktné motory produkujú viac škodlivých splodín, ale rnôžu mať vyššiu účinnosť ako štvortaktné.When the flue gas is released from the combustion cylinder into the atmosphere, harmful fumes of imperfect CO 2 and unburned hydrocarbons enter the atmosphere, as well as nitrogen oxides and the main product of CO ·? Combustion, which is considered to cause the greenhouse effect and gradually warm the atmosphere. These exhaust gases are produced by both 4-stroke and 2-stroke engines. Two-stroke engines produce more harmful emissions, but can also be more efficient than four-stroke engines.
Cieľom súčasného snaženia v oblasti výskumu spaľovacích motorov je dosiahnuť čo najvyššiu účinnosť pri minimálnej tvorbe škodlivých splodín. Spomínaný cieľ je nežné dosiahnuť hlavne zvýšením tepelnej účinností cez čo najvyšší kontpresuý tlak, ktorý priamo vplýva na stredný efektívny tlak v spaľovacomvalci. Preto je dôležité na efektívne využitie paliva využiť tieto zvýšené tlaky aj po výstupe zo spaľovacieho valca a a konanie práce.The aim of current efforts in the field of internal combustion engine research is to achieve the highest possible efficiency with minimal production of harmful emissions. This goal is gentle to achieve mainly by increasing the thermal efficiency through the highest possible compression pressure, which directly affects the mean effective pressure in the combustion cylinder. Therefore, it is important to use these increased pressures for efficient fuel utilization even after exiting the combustion cylinder and performing the work.
Podstata technického riešeniaThe essence of the technical solution
Podstatou technického riešenia je spaľovací motor pozostávajúci aspoň z jedného spaľovacieho valca a aspoň jedného expanzného valca, kde výfukový kanál spaľovacieho valca ústi do expanzného valca. Spaľovací valec pracuje ako klasický' 2-taktný alebo 4-taktný motora energia výfukových plynov zo spaľovacieho valca je využitá v expanznom valci, ktorého priemer je väčší ako priemer spaľovacieho valca.The essence of the technical solution is an internal combustion engine consisting of at least one combustion cylinder and at least one expansion cylinder, where the exhaust channel of the combustion cylinder opens into the expansion cylinder. The combustion cylinder operates as a conventional 2-stroke or 4-stroke engine. The exhaust gas energy from the combustion cylinder is used in an expansion cylinder whose diameter is larger than the diameter of the combustion cylinder.
Spaliny z» spaľovacieho valca prúdia do expanzného valca, kde odovzdávajú svoju energiu cez piest expanzného valca. Vyšší konrpresný tlak, ktorý je podmienkou vyššej účinnosti motora, zvyšuje tlak výfukových plynov, ktorý je možné využiť v expanznom valci a pripadne v tuibodúchadíe na konanie ďalšej práce, a tý m lepšieho využitia energie paliva.The flue gases from the combustion cylinder flow into the expansion cylinder, where they transfer their energy through the piston of the expansion cylinder. Higher compression pressure, which is a condition for higher engine efficiency, increases the exhaust gas pressure, which can be used in the expansion cylinder and possibly in the tube to perform further work, and thus better use of fuel energy.
Prehľad obrázkov na výkresochOverview of figures in the drawings
Na obr. č. 1 je znázornená schéma technického riešenia štvorvaícového motora s expanznými valcami, ktorý je v iakoirto usporiadaní tvorený dvomi funkčnými celkami. Jeden celok pozostáva zo spaľovacieho valca 1, resp. 10 a e^anzného valca 3, resp. 8.In FIG. no. 1 shows a diagram of the technical solution of a four-cylinder engine with expansion cylinders, which in such an arrangement is formed by two functional units. One unit consists of a combustion cylinder 1, resp. 10 and the expansion roller 3, resp. 8th
Príklady uskutočneniaExamples of embodiments
4-valcový motor znázornený naobr. 1 je zložený z dvoch funkčnýchcelkov. Tento motor má štyri valce v zložení: dva valce expanzné 3 a 8, ktoré majú väčší priemer a dva valce spaľovacie 1 a 10, ktoré majú menší priemer.The 4-cylinder engine shown in FIG. 1 is composed of two functional units. This engine has four cylinders in the composition: two expansion cylinders 3 and 8, which have a larger diameter, and two combustion cylinders 1 and 10, which have a smaller diameter.
Spaľovacie valce 1 a 10 obsahujú nasávacie kanály 5 a 15 a výfukové kanály 6 a 12, ktoré lístia do expanzných valcov 3, resp. 8. Tlak plynov, ktorý vzniká vplyvom horenia paliva v spaľovacom valci 1, tlačí na piest 2, ktorý sa pohybuje z HU do DU. V expanznom valci 3 prebieha vytláčanie spalín do výluku. Piest 2 sa následne pohybu® z DU do HU a zároveň sa otvára výfukový ventil 13. Spaliny sú vytláčané do e^anarého valca 3, kde tlačia na piest 4, a tým vykonávajú dodatočnú prácu.The combustion cylinders 1 and 10 comprise intake ducts 5 and 15 and exhaust ducts 6 and 12, which leaf into the expansion cylinders 3 and 3, respectively. 8. The gas pressure, which is caused by the combustion of the fuel in the combustion cylinder 1, presses on the piston 2, which moves from HU to DU. In the expansion cylinder 3, the flue gases are expelled into the discharge. The piston 2 is then moved from the DU to the HU and at the same time the exhaust valve 13 is opened. The flue gases are forced into the primary cylinder 3, where they press on the piston 4, thus performing additional work.

Navrhované riešenie je výhodne využiteľné hlavne v motoroch, ktoré pracujú v 2-taktnom režime. Výhodou 2-taktného motora je obvykle vyššia účinnosť ako pri 4-taktnom. Zároveň však výfukové plyny 2-taktného motora obsahujú väčší podiel CO, nespálených uhľovodíkov a zvyškov oleja. V súčasnosti je snahaThe proposed solution can be advantageously used mainly in engines that operate in 2-stroke mode. The advantage of a 2-stroke engine is usually higher efficiency than a 4-stroke.
