Eminyakeni yakamuva, izinto zikagesi zifinyelele ezintweni, kuze kube muva nje, besicabanga ukuthi bezigcinelwe omakhenikha. Uhlelo lwenkampani I-Freevalve - okuyingxenye yebhizinisi likaChristian von Koenigsegg, umsunguli wohlobo lwe-hypercar enegama elifanayo - ingesinye sezibonelo ezinhle kakhulu.
Yini entsha?
Ubuchwepheshe be-Freevalve buyakwazi ukukhulula izinjini ezivuthayo ohlelweni lokulawula ama-valve ngomshini (sizobona ukuthi yiziphi izinzuzo kamuva). Njengoba sazi, ukuvulwa kwama-valve kuncike ekuhambeni kwemishini yenjini. Amabhande noma amaketanga, axhunywe ku-crankshaft yenjini, asabalalisa amandla ngamasistimu ancike kuwo (ama-valve, isimo somoya, i-alternator, njll.).
Inkinga ngezinhlelo zokusabalalisa ukuthi zingenye yezinto eziphuca injini ukusebenza kwayo, ngenxa ye-inertia edalwe. Futhi ngokuphathelene nokulawulwa kwama-camshafts nama-valve, njengoba kuyisistimu yemishini, ukuhluka okuvunyelwe ukusebenza kulinganiselwe kakhulu (isibonelo: uhlelo lwe-VTEC lwe-Honda).
Esikhundleni samabhande endabuko (noma amaketanga) adlulisela ukunyakaza kwawo kuma-camshafts, sithola ama-actuator womoya.
Sesikushilo lokho, sifinyelele esiphethweni sokuthi ukufaneleka kwesistimu edalwe yinkampani ka-Christian von Koenigsegg kuwukungafaneleki kwamasistimu akhona ezinjinini zamanje: (1) ikhulula injini kuleyo inertia futhi (okubili) ivumela ukuphathwa kwamahhala kwezikhathi zokuvula i-valve (ukungenisa noma ukukhipha).
Yiziphi izinzuzo?
Izinzuzo zalolu hlelo ziningi. Eyokuqala sesishilo kakade: inciphisa inertia yemishini ye-motor. Kodwa okubaluleke kakhulu inkululeko enikeza i-electronics ukulawula isikhathi sokuvula ama-valve, kuye ngesivinini senjini kanye nezidingo ezithile zomzuzwana othile.Ngesivinini esiphezulu, isistimu ye-Freevalve ingakhuphula i-amplitude yokuvula i-valve ukuze ikhuthaze i-homogeneous inlet (kanye ne-outlet) yamagesi. Ngesivinini esiphansi, isistimu ingasho ukuvuleka okungasho lutho kwama-valve ukukhuthaza ukuncipha kokusetshenziswa. Ekugcineni, uhlelo lweFreevalve lungakwazi ngisho nokuvala amasilinda ezimeni lapho injini ingasebenzi ngaphansi komthwalo (umgwaqo oyisicaba).
Umphumela osebenzayo ungamandla engeziwe, i-torque eyengeziwe, ukusebenza kahle okukhulu nokusetshenziswa okuphansi. Inzuzo mayelana nokusebenza kahle kwenjini ingafinyelela ku-30%, kuyilapho ukukhishwa kwegesi kungancishiswa kuze kufike ku-50%. Kuyaphawuleka, akunjalo?
Isebenza kanjani?
Esikhundleni samabhande endabuko (noma amaketanga) adlulisela ukunyakaza kwawo kuma-camshafts, sithole ama-actuator womoya (bona ividiyo) kulawulwa yi-ECU, ngokwale mingcele elandelayo: isivinini senjini, indawo yepiston, indawo ye-throttle, shift gear kanye nesivinini.
Izinga lokushisa lokungenisa kanye nekhwalithi kaphethiloli ezinye izici ezingacatshangelwa lapho kuvulwa ama-valve okungena ukuze kusebenze kahle kakhulu.
"Ngenxa yezinzuzo eziningi, kungani lolu hlelo lungakathengiswa?" uyabuza (futhi kahle kakhulu).
Iqiniso liwukuthi, lobu buchwepheshe buqhele kakhulu ekukhiqizeni ngobuningi. AmaShayina avela kwaQoros, umenzi wezimoto waseShayina, ngokubambisana neFreevalve, ufuna ukwethula imodeli ngalobu buchwepheshe ekuqaleni kuka-2018. Kungase kube ubuchwepheshe obubizayo, kodwa siyazi ukuthi ngokukhiqiza ngobuningi amanani azokwehla kakhulu.
Uma lobu buchwepheshe buqinisekisa izinzuzo zabo zethiyori ekusebenzeni, kungaba enye yezinguquko ezinkulu ezinjinini ezivuthayo - akubona kuphela, bona ukuthi i-Mazda yenzani...
