Chii chinonzi "dual camera" zvinorevei?
Kutengesa chinhu chakakosha chekutengesa motokari. Kungave kushambadza Chevrolet hombe block V8 se "injini yemakonzo" kana iyo ine mukurumbira "six-cylinder Hemi", vatengi vanowanzokwezvwa nezvigadzirwa zvemotokari kana zvikamu zvine zita rekugadzira remhando pane chakasarudzika chigadzirwa. Imwe yeanonyanya kusanzwisiswa nicknames ndeye mapatya cam injini kumisikidza. Kunyange zvazvo zviri kuwedzera kuwanda mumotokari nemarori emazuva ano, vatengi vakawanda havazivi zvazvinoreva chaizvo kana kuti zvinoshandisirwa chii.
Pazasi pane zvimwe chokwadi pamusoro pekuti twin cam engine chii, kuti inoshanda sei, uye zvakanakira kuishandisa mumotokari yemazuva ano, rori, uye SUV injini.
Kutsanangura Dual Camera Configuration
Yechinyakare piston-inotyairwa mukati memoto injini ine crankshaft imwe chete inotyaira mapiston uye madonzvo ekubatanidza akabatanidzwa necheni kune imwechete camshaft inovhura nekuvhara mavharuvhu ekupinza uye epoust panguva yemaitiro mana. Iyo camshaft haisati iri pamusoro pemasilinda kana pedyo nemavharuvhu pachawo, uye matepi anoshandiswa kuvhura nekuvhara mavharuvhu.
A twin cam injini ine maviri camshafts, kunyanya kaviri pamusoro camshaft kana DOHC, iyo inosarudza nzvimbo yechitima chevhavha. Kunyange zvichinzwika kutonhorera kutaura kuti une mapatya cam injini, haisi nguva dzose nguva yakakodzera.
Mune maviri-cam injini, maviri camshafts ari mukati mehumburumbira musoro, iri pamusoro pemasilinda. Imwe camshaft inodzora mavharuvhu ekutora uye imwe inodzora mavharuvhu ekupedza. Iyo DOHC injini ine akati wandei maficha ayo akasiyana nemagadzirirwo ayo. Semuenzaniso, maoko e rocker madiki kana anogona kunge asipo zvachose. Kona yakafara inoonekwa pakati pemhando mbiri dzevharuvhu pane imwechete pamusoro camshaft kana SOHC.
Injini dzakawanda dzeDOHC dzine mavharuvhu akawanda pane imwe silinda, kunyange izvi zvisingadiwi kuti injini ishande. Theoretically, mamwe mavharuvhu pacylinder anovandudza injini simba pasina kuwedzera mhepo. Mukuita, izvi hazvisi zvechokwadi nguva dzose. Zvinonyatsoenderana nekugadziriswa kweinjini kana rudzi urwu rwekugadzika musoro we cylinder ruchabatsira.
Zvakanakira Dual Camera
Nyanzvi makanika vanobvuma kuti nzira yakanakisa yekuvandudza kushanda kweinjini ndeyekuona kuyerera kwemhepo kuburikidza nemasilinda misoro. Nepo zvitoro zvakawanda zveinjini zvichiita izvi nekukudza mavharuvhu ekupinza nekupedza simba, manifolds, uye kutakura nekupukuta makamuri kuti afambe zvakanaka, vagadziri vemotokari vakatora mavharuvhu akawanda-per-cylinder. Iyo DOHC dhizaini inobvumira kushoma kudzora kuyerera kwemhepo pakumhanya kwakanyanya. Kana injini zvakare iine dhizaini yakawanda-vhavha, zvakare yakavandudza kupisa kwekuvandudza kushanda nekuda kwekuiswa kwe spark plug.
Nekuti DOHC kana mapatya cam injini dzakanatsiridza kuyerera kwemhepo kuburikidza nemasilinda, iwo anowanzo kuenzana ane simba uye anopa kukurumidza kuri nani. Vanogonawo kuvandudza kushanda zvakanaka, zvinoreva kuchengetedza mari pachiteshi chegesi. Mukuwedzera, injini dzeDOHC dzinowanzomhanya dzakanyarara uye dzakapfava. Nhasi, twin cam engines dziripo kune dzakasiyana siyana dzemotokari, kubva pakupinda-level hatchbacks kusvika kumitambo-inosimudzira mota dzemitambo.
