Uphethiloli injini

Gasoline izinjini - uhlobo yangaphakathi omlilo engine, lapho uphethiloli onomfutho ibangelwa ube yinhlansi umsuka kagesi. Amandla kuzo kuyaqashwa futhi elawulwa ngokulungisa ukugeleza komoya.

Gasoline injini kuqhathaniswa ne udizili has a ijubane okukhulu futhi umthamo (ilitha) umthamo, futhi vibration umsindo - Kunalokho, ngezansi. Ingxube ezivuthayo kubuswa ikakhulukazi quantitatively kungani at amandla ongaphakeme futhi ngokwesilinganiso (operation evamile imoto) ephumelela kokucindezelwa ongaphakeme. Ngakho-ke, kukhona ababuthakathaka omlilo kahle futhi kulandela ukunwetshwa ke - kungakho abalulekile petrol.

It kuvela ukuthi nge okuzisholo amandla nekusebenta injini enjalo ngaphansana 20% ngo-diesel. Kwimodi ngokwengxenye le Umehluko 40% noma ngaphezulu. Leli qiniso liye ngokuphindaphindiwe waqinisekisa nokuqhathanisa ukusebenza ukuhlolwa kanye nokuvivinywa izimoto nge zombili izinhlobo izinjini kwamandla alinganayo.

Uma sikhuluma degree of ubuthi qeda kwekhabhoni izinto gaseous, kungase kuqashelwe ukuthi ngenxa yokuthuthukiswa uphethiloli izinjini kule minyaka eyishumi eyedlule, lesi sibalo kwaba ngcono kakhulu. It uye wathonya futhi kulawulwa processor piston iDemo umjovo ngqo nge Imibhobho esemzimbeni. Ngesikhathi esifanayo, ngokusho kongoti eminingi ehlonishwayo kusukela ehola izinkampani zezimoto, ngokomongo samanje izimfuno eliphezulu izinyathelo zokuvikela ngemvelo futhi imvelo likaphethiloli izinjini namanje kunabayeni diesel izinjini - kwezithembiso kakhulu futhi ihlangabezana okungenhla nezimfuneko izinjini. Nokho, imizamo ukuqinisekisa uphinde uthuthukise ukusebenza kwemvelo wokuqala akumvimbi.

Uma imoto ifakwe injini uphethiloli, khona-ke ngokuvamile kwenzeka 4 zokusebenza ngesishayo

• Inlet. Lapho le piston elilodwa isilinda wehlela futhi injini, efana futha, ngokusebenzisa valve evulekile "sucks" upetrol kanye ne air.
• Kokucindezela. Bobabili valve - itheku futhi esidayisa - zivaliwe. Manje, piston liphuma phezulu, ukugxisha ingxube emoyeni nophethiloli. Ekupheleni kwalesi unhlangothi -plug inhlansi yakha inhlansi lapho wokhela ingxube kakade onomfutho.
• Stroke. Namanje valve avaliwe eyanele kanye qeda valve, nophethiloli uyaphakama. amandla omlilo mkhiqizo ngokushesha likhula ivolumu, ngenxa ngalo odlulela piston phansi. I piston yena, oshayela crankshaft nge induku yokuxhuma.
• Exhaust. I piston liphuma futhi. Valve qeda kuvula kanye amagesi qeda elise ohlelweni qeda, bese - emkhathini.

Kukhona ezinye izici yokusebenza injini uphethiloli. Izinkinga, ngenxa okungase kudingeka ukulungiswa likaphethiloli izinjini - uphethiloli yekhwalithi ephansi, ukwehluleka noma ikhwalithi embi yesondlo, mileage okusezingeni eliphezulu. Ukuze ukulungiswa, sicela uthintane emagalaji onguchwepheshe, lapho izingcweti abanolwazi ngokuhambisana nezidingo zonke izinhlobo imikhiqizo kanye namakhadi zobuchwepheshe, okuyinto alawule yonke imisebenzi wesondlo emshinini ngamunye noma engeyokuqala.

Efingqa, kubalulekile ukuba ucacise izinzuzo, okuyinto libhekene injini uphethiloli. Okokuqala, kuba - amandla aminingi esilinganayo. Lokhu kungenxa okusezingeni eliphezulu kuhle kwegezi uphethiloli idliwe - uphethiloli noma ethanol. Ngaphezu kwalokho, injini uphethiloli ngokwayo has a design elula izindleko zalo ingaphansi kwe-Inani lika dizili. Futhi-ke, it uyagijima buthule, okuyinto ikakhulukazi sebeqala bayakwazisa abashayeli peresevshie kusukela likaphethiloli ku-diesel emotweni, ngoba abakwazi ukujwayela elikhulu motor ukugijima.
