Description
Vynález sa týká piestového spalovacieho motora bez klukového mechanizmu s hydrostatickým prenosom výkonu.The invention relates to a piston internal combustion engine without a crank mechanism with hydrostatic power transmission.
Doteraz používaný piestový spalovací motor s vnútorným spalováním a klukovým mechanizmom je velmi používaný na pohon róznych mobilných zariadení, pracovných strojov a automobilov. Jeho výkon bývá regulovaný množstvom alebo kvalitou pohonnej zmesi dopravenej do spalovacích priestorov. Rozsah otáčok a odoberaného krútiaceho momentu sa zvyčajne upravuje stupňovou alebo plynulou převodovkou. Motory v takýchto strojoch musia často pracovat aj v menej priaznivých oblastiach charakteristiky a v režime tzv. volnoběhu, čím sa zvyšuje podiel neužitočne spotřebovaného paliva a množstvo nežiadúcich exhalátov vo výfuku.The internal combustion piston engine with crank mechanism used so far is widely used to drive various mobile devices, working machines and cars. Its output is regulated by the quantity or quality of the fuel mixture delivered to the combustion chamber. The range of speed and torque taken is usually adjusted by a stepwise or stepless transmission. Engines in such machines often have to work even in less favorable areas of the characteristic and in the so-called mode. idle, increasing the proportion of useless fuel and the amount of unwanted exhaust emissions.
Vyššie uvedené nedostatky odstraňuje spalovací motor bez klukového mechanizmu s hydrostatickým prenosom výkonu podlá vynálezu, ktorého podstata spočívá v tom, že na piestnici je spolu s piestom na čerpanie kvapaliny pomocný piest hydraulicky viazaný s protibežným piestom, nad ktorým sa nachádza priestor so stlačeným vzduchom. Na výstupe z čerpadla s piestom je připojený hydraulický akumulátor, pričom tlakový snímač je cez ovládací člen spojený so západkou.The above-mentioned drawbacks are overcome by the internal combustion engine without crank mechanism with hydrostatic power transmission according to the invention, which consists in that on the piston together with the piston for liquid pumping the auxiliary piston is hydraulically coupled to the counter piston over which the compressed air space is. A hydraulic accumulator is connected at the outlet of the piston pump and the pressure sensor is connected to the pawl via the actuator.
Spalovací motor pódia vynálezu je regulovaný přerušováním chodu v závislosti na odbere energie z plynohydraulického akumulátore pri rovnakej dávke paliva pre každý zdvih. Odpadajú přechodové režimy a volnoběh, motor sa samočinné spustí pri poklese tlaku v akumulátore a zastaví, keď tlak stupně na určenú hodnotu. Výhodou riešenia je, že spalovanie prebieha pri každom zdvihu v rovnakých podmienkach volených z hladiska spotřeby paliva, zloženia výfukových plynov a hluku.The internal combustion engine of the invention is controlled by interruption of operation depending on the power consumption of the gas-hydraulic accumulator at the same fuel dose for each stroke. Transition modes and idle are eliminated, the engine starts automatically when the battery pressure drops and stops when the stage pressure reaches the specified value. The advantage of the solution is that the combustion takes place at each stroke under the same conditions chosen from the point of view of fuel consumption, exhaust composition and noise.
Na pripojenom výkrese je schematicky znázorněný rez spalovacím motorom podlá vynálezu a naznačené niektoré jeho příslušenstvo.In the accompanying drawing, a cross-section of a combustion engine according to the invention and some of its accessories are shown schematically.
Spalovací motor pozostáva z valca 1, v ktorom sa pohybuje pracovný piest 2 spojený s piestnicou 3. Na válci 1 sú vyplachovacie kanály 4 a výfukové kanály 5. Vzduch sa nasáva cez samočinný ventil B, konštantnú dávku paliva vstrekuje čerpadlo 7 cez dýzu 8. Čerpadlo 7 je uvádzané do pohybu výstupkom 9 na piestnici 3, s ktorou je spojený piest 10 čerpajúci kvapalinu z nádrže 11 do akumulátora 12 a ku spotřebiči 20. Tlak v akumulátore 12 sleduje tlakový sní225153 mač 13 a pomocou ovládacieho člena 14 přestavuje západku 13. Pomocný piest 16 a protibežný piest 17 sú časťami vratného zariadenia využívajúceho energiu stlačeného plynu v priestore 18. Ventil 19 zabezpečuje kontrolu množstva kvapallny vo vratnom zariadení. Hmota protibežného piestu 17 eliminuje vonkajšie účinky zrýchíujúcich sil piestov 2, 10, 16 a piestnice 3. Na válci 1 je usporiadaná tepelná a zvuková izolácia 21 motora. Na výkrese nie je zakreslené zariadenie na natiahnutie piestov 2, 10, 16 do dolného úvratu pre případ prvého startu, ktoré može využívat energiu z akumulátoreThe internal combustion engine consists of a cylinder 1 in which the working piston 2 is connected to the piston rod 3. On the cylinder 1 there are flushing channels 4 and exhaust channels 5. The air is sucked through the automatic valve B, a constant dose of fuel is injected by the pump 7 through the nozzle 8. 7 is actuated by a projection 9 on the piston rod 3 to which the piston 10 pumping liquid from the tank 11 to the accumulator 12 and to the consumer 20 is connected. The pressure in the accumulator 12 follows the pressure sensor 22153 and adjusts the pawl 13. 16 and the counter piston 17 are parts of a return device using compressed gas energy in the space 18. The valve 19 controls the amount of liquid in the return device. The mass of the counter piston 17 eliminates the external effects of accelerating forces of the pistons 2, 10, 16 and the piston rod 3. Thermal and acoustic insulation 21 of the motor is arranged on the cylinder 1. The drawing does not show a device for pulling the pistons 2, 10, 16 into the bottom dead center for the first start which can use the battery power

Spalovací motor podl'a vynálezu je použitelný ako Zdroj tlakovej kvapaliny pre pohon strojov, například rýpadiel a pre trakčně účely. V spojení s trakčným regulovaným hydromotorom tvoří automatickú převodovku a čiastočne využívá premenu pohybovej energie vozidla pri brzdění na doplnenie akumulátora.The internal combustion engine of the invention is useful as a source of pressurized fluid for propulsion of machines, for example excavators, and for traction purposes. In conjunction with a traction controlled hydraulic motor, it forms an automatic transmission and partially utilizes the conversion of motor vehicle energy during braking to replenish the battery.
