Motokari mana mbonje injini

Rinoumbwa zvina injini sepombi, izvo akatasva pamusoro crankcase uye pamusoro Akanyatsovharwa musoro. Carter pasi tireyi pei. In humburumbira mavharuvhu musoro vari kuisa - the Inlet uye nzira yokubudisa, kuti kamwene kuti jekiseni peturu (Diesel) injini kana dzomoto kuvesa (peturu). Mukati pisitoni inofamba, kwakabatana kuburikidza pisitoni hoko pamwe rokumusoro musoro unobva tsvimbo. Rezasi mukuru unobatanidza shamhu chakafukidzwa cervix crankshaft magazini huru izvo akatasva mabheyaringi. The pisitoni ari humburumbira chakaputirwa nokuda chaiwo zvindori. Panoperera ari crankshaft wakasimba flywheel.

Akadana yokumusoro akafa pfungwa nzvimbo inogarwa iri pisitoni pakupera kwayo zvichikwira sitiroko, Musana akafa nguva inonzi nzvimbo yaigarwa panoperera pasi kufamba.

Kungwarira anonzi kwebasa pisitoni kubva pakati akafa mumwe. Musha akaumba pamusoro payo kana kuona pana TDC, kuti combustion mukamuri chinhu parameter. injini misha kana misha vhoriyamu - ndiyo mari aburitswa pisitoni kana uchifamba kuvakafa pfungwa. The Vhoriyamu humburumbira - zvachose kukosha combustion kamuri nokushanda.

Compression reshiyo chinhu chinokosha, iro rinorondedzerwa so nhamba izere humburumbira vhoriyamu kune zvachose Vhoriyamu combustion yomukati. Modern kuroorwa-humburumbira injini ine compression reshiyo anenge 10. The chete-humburumbira mana sitiroko injini ine yepamusoro compression reshiyo, kwete asingasviki 20.

Four neronda injini pakutanga ari kudya sitiroko kana kudya vharuvhu anovhura, kana ari pisitoni anotanga kutamira kubva pamusoro akafa pakati. In muitiro anozunungusa Vacuum achiumbwa humburumbira mana-ronda injini anogamuchira musanganiswa mhepo uye mafuta mhute, iyo inowanzonzi ine mafuta kana huni-mhepo nezvakasanganiswa.

Mushure pisitoni BDC kuchaitika, nokuda vachishandisa kutenderera crankshaft, anotanga kukwira kumusoro centre akafa, izvo vaiona pakutanga compression sitiroko. Izvi anovhara Inlet vharuvhu, uye yose kutenderera, zvose mavharuvhu dzakavharika. The combustible muvhenganiswa iri humburumbira panguva misha yacho pisitoni kuna TDC iri compressed, ayo tembiricha uye kumanikidzwa kuwedzera. Pane kunonyanyisa ukoshi apo compression pisitoni TDC. Asi sezvo mafuta combustion muitiro anotora dzimwe nguva yokuti combustible musanganiswa iri dzakaparira pachine, ari pisitoni asati kunosvika TDC pamusoro compression nevanga. Musanganiswa iri abatidzwa wemagetsi dzomoto iyo akasvetuka pakati electrodes ari chivhariso. Kubva panguva chinopa BTDC, iyo crank yorusvingo akadana pakona kuti precession kuvesa.

In chinokosha nhamba magasi simba-unoparadza vasunungurwa panguva mafuta combustion, kudzvanya pamusoro pisitoni, iyo kuti injini kuita ina sitiroko kunoita munguva inotevera yokuvamba pamwe mavharuvhu akavharwa pisitoni sitiroko kubva TDC kuna BDC. Pedza Kurohwa rinotanga pashure sitiroko. Anovhura, kuti chiutsi vharuvhu uye pisitoni inofamba akananga TDC, displacing kuti chiutsi magasi mumhepo. Zvadaro, muna chete kutevedzana kutenderera inodzokororwa.
