I-prototype eyakhiwe yinkampani yaseMelika i-LiquidPiston yasetshenziswa okokuqala ngqa ku-kart.
Cishe eminyakeni emibili edlule, umsunguli we-LiquidPiston u-Alec Shkolnik wethule incazelo yesimanje yenjini endala ye-Wankel (eyaziwa ngokuthi inkosi ye-spin), umphumela weminyaka engaphezu kweshumi yocwaningo nentuthuko.Njengezinjini ezijwayelekile ezijikelezayo, injini ye-LiquidPiston isebenzisa “ama-rotor” esikhundleni sama-piston endabuko, okuvumela ukunyakaza okushelelayo, ukuvutha komugqa kanye nezingxenye ezimbalwa ezihambayo.
Nakuba kuyinjini ejikelezayo, u-Alec Shkolnik ngaleso sikhathi wayehlose ukuziqhelelanisa nezinjini ze-Wankel. "Kuwuhlobo lwenjini ye-Wankel, ekhishwe ngaphakathi, idizayini exazulula izinkinga ezindala ngokuvuza nokusetshenziswa ngokweqile", kuqinisekisile u-Shkolnik, naye indodana kanjiniyela wemishini. Ngokusho kwenkampani, le njini ilula futhi isebenza kahle, inamandla ngekhilogremu ngayinye ngaphezu kwesilinganiso. Ukusebenza kwayo okuvamile kuchazwe kuvidiyo engezansi:
AKUMELE UPHUTHELWE: Imboni lapho i-Mazda ikhiqize khona “inkosi ye-spin” i-Wankel 13B
Manje, inkampani ithathe isinyathelo esibalulekile ekuthuthukisweni kwenjini ejikelezayo ngokusetshenziswa kwe-prototype ku-kart, njengoba kuboniswe kuvidiyo engezansi. I-prototype eyakhiwe nge-aluminium enamandla angu-70cc, amandla angu-3hp nangaphansi kuka-2kg ithathe indawo yenjini engu-18kg ngempumelelo. Ngeshwa, ngeke silibone leli bhulokhi kumodeli yokukhiqiza maduze. Kungani? "Ukuletha injini entsha emakethe yezimoto kuthatha okungenani iminyaka eyisikhombisa futhi kuhilela izindleko zamaRandi ayizigidi ezingu-500, lokhu kunjini enobungozi obuphansi", kuqinisekisa u-Shkolnik.
Okwamanje, i-LiquidPiston ihlela ukusebenzisa injini ejikelezayo ezimakethe ze-niche ezifana nama-drones namathuluzi okusebenza. Ngokusobala, inkampani ixhaswa uMnyango Wezokuvikela wase-US. Injini ye-rotary inga-odwa ngewebhusayithi esemthethweni yenkampani.
