Kanjani futhi kungani kudingeka ulungise injini speed kokungenzi lutho

Ngo ukusetshenziswa imoto ngayinye, ziba khona izikhathi lapho injini awutholi noma yimuphi umthwalo ngaphandle amabutho friction, kodwa baqinisile abanazo, futhi ngenxa yalokho, abayingxenye yayo. Exposure, ngenxa la mandla, uthambise ahlukahlukene, kodwa zisekhona.

motor Lo msebenzi ubizwa ngokuthi "kokungenzi lutho". Ngalesi sikhathi, ukudluliswa inikwe amandla ukubandakanya kushaft okokufaka, ngakho ukujikeleza crankshaft ayihambi amasondo. Kodwa ungacabangi ukuthi imoto kumele kube ukuthi iyunithi isebenza ngaphansi hood at lutho. Abashayeli abaningi basebenzisa okuthiwa esondweni uphethiloli umnotho. Ngokwesibonelo, ngaphambi kokuba abe amakhulu kwesokunxele amamitha, futhi ijubane kuphezulu ke ungafaka hlangothi futhi "roll" aphume inertia. Ngakolunye uhlangothi - ke umnotho, ngakolunye - ayikwazanga ukhule ufike ijubane lapho mhlawumbe wathatha uphethiloli okwengeziwe noma okunye fuel, esebenzisa imoto.

Idling udlala indima ebalulekile ukusebenza, ngoba kule modi injini "baphile" Isikhathi esiningi. Lokhu kusho ukuthi ngaphambi ukuwushintsha, sibala ukudluliswa, kuthatha isikhathi esithile. Per actuation, kuyinto encane, kodwa uma nje ukubala zonke igiya ushintsho ngosuku, ngesonto, ngenyanga, ngonyaka ... izibalo abasakwazi umxhwele.

Eqinisweni, injini speed kokungenzi lutho ongamtshela ngesimo sakhe. Okokuqala, uma yamabhola antantayo engenzi lutho, kusho ukuthi uhlobo oluthize uhlelo akusebenzi kahle, hhayi njengoba kufanele. Ngokwesibonelo, kuhle ukucabangela ukulungisa carburetor noma hlola electronic control unit. Ngaphezu kwalokho, kungase kube nezinkinga ukuthungela, okuyinto lula impela hlola. Kulokhu, udinga nje ukuqinisekisa efanele ukufakwa okwamanje ukuthungela, kanye nokusulwa evamile. Uma konke kuhamba kahle, singaya phambili. Idling ingase iphazamiseke ngenxa ukungasebenzi futha fuel, ikakhulukazi i-umfutho ophakeme. Kulokhu, kuyothiwa injected, kodwa hhayi ngokwanele, okuholela operation engazinzile ngezikhathi. Futhi, ukuqinisekisa yobunzima salo lonke uhlelo fuel, kusukela emoyeni angene igcwele nemiphumela efanayo.

Ngaphezu kwalokho, injini kufanele usebenze "lenyama" idling injini efudumele, akumele leqe 900-1000 ngomzuzu, okuyinto ngokwesilinganiso, ezinye izinjini ke ingaphansi. Uma ijubane kokungenzi lutho kugujwe, kodwa kunamasiko uqala "ukuntanta" nge ukwehla kuze kube yilo mthetho, kuwufanele ecabanga isimo eqenjini piston. Okokuqala, emasongweni piston. bafake yabo, ngokuvamile uhambisana i anda petrol, kanye iconsi sina wangaleso revs ongaphakeme. Ngaphezu kwalokho, piston indandatho ukugqoka ngokulinganayo, futhi ngenxa yalokho, kanye kokucindezelwa namafutha bushelelezi ukuguga, okuholela ekwandeni kwabantu uwoyela ukusetshenziswa. Lokhu kungabonakala uma ngezikhathi hlola uwoyela engine ezingeni.

Isizathu ukuqinisekisa enjalo kufanele ibe intuthu blue kusuka ipayipi qeda, okuyinto is akubone akunakwenzeka. Ekuphetheni, kuyafaneleka ethi ijubane kokungenzi lutho - lena umsebenzi sína, okumele zigcinwe zisesimweni esihle, kanye nezinye izinhlelo imoto.
