Isihloko: Isithuthuthu esine-silinda esisodwa

Izithuthuthu ezine-cylinder ezine-stroke ziwuhlobo lwesithuthuthu oluvame ukutholakala emhlabeni wamabhayisikili omgwaqo. Lawa mabhayisikili aziwa ngokwethembeka, ubulula, nokusebenza kahle kwawo. Kulesi sihloko, sizohlola izici zezithuthuthu ezine-cylinder ezine-stroke kanye nezinzuzo zazo kanye nokubi.

Esinye sezici ezibaluleke kakhulu zezithuthuthu ezine-cylinder ezine-stroke ukucushwa kwenjini yazo. Lawa mabhayisikili ngokuvamile afaka isilinda esisodwa esinemivimbo emine ngokuzungeza ngakunye (i-spool valve, i-take, compression, kanye ne-exhaust). Injini ifakwe ku-crankshaft ezungeza ama-degree angu-360, futhi i-piston ihamba yehla yenyuka ngaphakathi kwesilinda ukwenza imivimbo emine.

Enye yezinzuzo ezibalulekile zezithuthuthu ezine-cylinder ezine-stroke ukulula kwazo. Injini ilula uma kuqhathaniswa ukuyakha nokuyinakekela, futhi zimbalwa izingxenye ezingahluleka. Lokhu kubenza bathembeke futhi kube lula ukuzinakekela. Ukwengeza, ubulula bomklamo wenjini busho ukuthi zisebenza kahle uma kuqhathaniswa, zikhiqiza itorque ephezulu kanye nekhabhoni ephansi.

Enye inzuzo ebalulekile yezithuthuthu ezine-cylinder ezine-stroke isisindo sazo. Ngenxa yokuthi kunesilinda esisodwa kuphela, kunesisindo esincane ongasithwala. Lokhu kwenza amabhayisikili abe lula ukuwagibela futhi akwazi ukulawuleka ekuhambeni okude. Ukwengeza, isisindo esiphansi samabhayisikili siwenza ahlale isikhathi eside futhi akwazi ukuphatha indawo enzima.

Izithuthuthu ezine-Single-cylinder ezine-stroke nazo zinedumela lokushelela futhi zithule. Idizayini yenjini enemivimbo emine isho ukuthi kunokuphenduka okumbalwa ngomzuzu, okuphumela kumsindo wenjini ophansi ojatshulelwa abagibeli abaningi. Ukwengeza, isilinda esisodwa sisho ukuthi kunomsindo omncane okhiqizwa injini, okwenza amabhayisikili akhululeke kakhudlwana ukugibela ezindaweni ezinomsindo.

Kodwa-ke, izithuthuthu ezine-cylinder ezine-stroke zinemibi embalwa. Okunye okubaluleke kakhulu isilinganiso sazo samandla nesisindo. Nakuba zingase zisebenze kahle futhi zithembeke, ngokuvamile zinezilinganiso eziphansi zamandla nesisindo, okungenza kube nzima ukusheshisa ngokushesha. Ukwengeza, isilinganiso esiphansi samandla nesisindo singabenza kube nzima ukulawula ithrafikhi enesivinini esikhulu.

Okunye okungalungile kwezithuthuthu ezine-cylinder ezine-stroke inani lazo. Ngenxa yokuthi ziwuhlobo olungavamile lwesithuthuthu, ngokuvamile zibiza kakhulu kunezinye izinhlobo zamabhayisikili. Lokhu kungenza kube nzima kubagibeli abangu-预算有限.

Ekuphetheni, izithuthuthu ezine-cylinder ezine-stroke ziwuhlobo oluyingqayizivele noluthakazelisayo lwesithuthuthu. Banedumela lokwethembeka, okulula, nokusebenza kahle. Nakuba benokungalungi okumbalwa, njengesilinganiso samandla nesisindo sabo kanye nenani, kuseyindlela ejabulisayo nejabulisayo yokugibela.
