Atkinson Cycle Injini

Iyo Atkinson cycle injini injini yekupisa yemukati. Yakagadzirwa naJames Atkinson muna 1882. Izvo zvakakosha zveinjini ndeyekuwana yakakwira kupisa kwekuita, ndiko kuti, kuderera kwemafuta.

Iyi mhando yekupisa inosiyana neyakajairwa Otto kutenderera nekuvhura kwenguva refu kwevharuvhu yekukweva, iyo inoenda muchikamu chekumanikidza apo piston inosimuka nekumanikidza musanganiswa. Izvi zvinotungamira kune chokwadi chekuti chikamu chemusanganiswa watoyamwa-mukati chinosundirwa kunze kwehumburumbira ichidzokera mupombi yekusveta. Chete mushure meizvi iyo valve yekupinda inovhara, ndiko kuti, mushure mekunge musanganiswa wemafuta uchiyamwa mukati, uchiteverwa neimwe "kubuda" uye chete ipapo kudzvinyirira kwakajairika. Injini inoita sekunge ine diki yekusimuka nekuti iyo yekumanikidza uye yekuwedzera ratios zvakasiyana. Kuenderera mberi kuvhurwa kwevhavha yekukweva kunoderedza iyo chaiyo yekumanikidza reshiyo. Sezvatotaurwa, iyi fomu yekupisa inobvumira chiyero chekuwedzera kuti ive yakakwira kupfuura reshiyo yekumanikidza uku ichichengetedza yakajairika compression pressure. Kuita uku kunobatsira pakuita zvakanaka kwekupisa nekuti chiyero chekumanikidza muinjini dzepeturu chinoganhurwa nechiyero cheoctane chemafuta anoshandiswa, nepo kuwedzera kwekuwedzera kunobvumira nguva yekuwedzera kwenguva refu (nguva yekupisa) uye nekudaro inoderedza kupisa kwegasi rekubuda - kukwirira kweinjini. . Muchokwadi, kushanda kweinjini yepamusoro kunotungamira kuderedzwa kwe10-15% mukushandiswa kwemafuta. Izvi zvinowanikwa kuburikidza nekushanda kushoma kunodiwa kudzvanya musanganiswa, pamwe nekudzikira kwekupomba uye kupera simba, uye iyo yambotaurwa yepamusoro yezita rekumanikidza reshiyo. Kusiyana neizvi, kukanganisa kukuru kweAtkinson cycle injini isimba rakaderera mumatita, iro rinobhadharwa nekushandiswa kwemotokari yemagetsi (hybrid drive) kana injini inowedzerwa ne turbocharger (Miller cycle), sezvakaita Mazda. Xedos 9 ine injini. injini 2,3 l.
