Eli nqaku liza kujonga nzulu kwiimpawu ezahlukeneyo, iiparameter zobugcisa, imigaqo yokusebenza, iimeko zezicelo, kunye nolwazi lokugcinwa kwenjini ye-LB170F, ikunika ukuqonda okubanzi kwale njini inomtsalane kakhulu.

Okokuqala, Isishwankathelo seNjini ye-LB170F

Injini ye-LB170F yi-single-cylinder, injini yepetroli epholiswe ngomoya opholisiweyo nge-four-stroke, epholiswe ngomoya ngokunyanzelekileyo. Yamkela ubuchwepheshe obuphambili kunye neengcamango zoyilo, iqinisekisa ukukhutshwa kwamandla okunamandla ngelixa ifezekisa iinjongo zokusebenza kakuhle, ukugcinwa kwamandla kunye nokukhuselwa kwendalo. Iimpawu zayo eziphambili ziquka ulwakhiwo oluncinci, ubunzima obuphantsi, ingxolo ephantsi, ukuqalisa nokugcinwa okulula, njl. Ezi nzuzo ziyenza ibonakale phakathi kweenjini ezininzi zepetroli ezincinci kwaye ibe ngumthombo wamandla okhethwayo kwiimashini zezolimo, izixhobo zegadi, ezincinci Ijenereyithakunye nezinye izixhobo.

Okwesibini, iiparameter zobugcisa zenjini ye-LB170F

(1) Iiparameter ezisisiseko

I-Bore × stroke: 70mm × 50mm. Olu lwakhiwo lobukhulu lwenza injini ikwazi ukubonelela ngamandla aneleyo ngelixa igcina umthamo omncinci.
Ukufuduka: 212ml. Ukutshintsha okuphakathi akuqinisekisi nje kuphela ukusebenza kwamandla enjini kodwa kukwaqwalasela ukonga amafutha.
Umlinganiselo woxinzelelo: 8.2:1. Umlinganiselo ophezulu woxinzelelo unceda ukuphucula ukusebenza kakuhle kobushushu benjini, ngaloo ndlela kuphucula amandla kunye nokonga amafutha.
Inkqubo yokutshisa: Isebenzisa i-transistor engasebenzisi thintano. Le ndlela yokutshisa ineengenelo zokutsha ngokuchanekileyo, ukuthembeka okuphezulu kunye nokugcinwa okulula, okunokuphucula ukusebenza kunye nobomi benkonzo yenjini ngempumelelo.
Indlela yokuqala: I-backwash etsalwa ngesandla/i-flashlight edityanisiweyo. Abasebenzisi banokukhetha ukuqalisa ngesandla okanye ukuqalisa ngombane ngokwemeko yokwenyani, nto leyo elula nekhawulezayo.
Umthamo wetanki yepetroli: I-3.6L, enokukwazi ukuhlangabezana nombane wenjini ixesha elide, inciphisa ukuphindaphindwa kokufakwa kwepetroli kwaye iphucule ukusebenza kakuhle.
Umthamo weoyile yenjini: 0.6L. Ubungakanani obufanelekileyo beoyile yenjini bunokuqinisekisa ukuthambisa kakuhle iindawo zangaphakathi zenjini kwaye kwandise ubomi benkonzo yenjini.
Ukusinda okushiyekile: Malunga ne-15kg. Ubunzima obulula benza kube lula ukuyifaka nokuyiphatha injini, ifanele izixhobo ezahlukeneyo ezincinci zoomatshini.

(2) Iiparameters zoKusebenza

Amandla aphezulu: Ngesantya sokujikeleza se-3600rpm, inokukhupha amandla aphezulu e-6.5 horsepower (malunga ne-4.85kW). Eli nqanaba lamandla lanele ukuqhuba uninzi lwezixhobo ezincinci zezolimo, izixhobo zegadi kunye nezinye izixhobo, ukuhlangabezana neemfuno zamandla zabasebenzisi kwimisebenzi yabo yemihla ngemihla.
I-torque ephezulu: Idla ngokufikelela kwi-torque ephezulu malunga ne-2500rpm, malunga ne-13.5N·m. Ukuphuma kwe-torque ephezulu kwenza injini ikwazi ukubonelela ngamandla aqinileyo nokuba isantya siphantsi, nto leyo eyenza ifaneleke kwizicelo ezifuna ukukhutshwa kwe-torque enkulu, njengeetrektara kunye Impompo Yamanzis.
Izinga lokusetyenziswa kwepetroli: ≤374g/kw·h. Izinga eliphantsi lokusetyenziswa kwepetroli lithetha ukuba injini inokonga amandla ngakumbi ngexesha lokusebenza, nto leyo enciphisa iindleko zokusebenzisa zomsebenzisi.
Izinga lokusetyenziswa kweoyile yokuthambisa: ≤6.5g/kw·h. Oku kubonisa ukuba injini ayisebenzisi kakhulu ioyile yokuthambisa ngexesha lokusebenza okuqhelekileyo, nto leyo enciphisa ukuphindaphindeka kokuphinda kusetyenziswe ioyile yokuthambisa kubasebenzisi. Kwangaxeshanye, ikwanciphisa umngcipheko wokungasebenzi kakuhle kwenjini okubangelwa kukusetyenziswa kakhulu kweoyile yokuthambisa.

Okwesithathu, umgaqo wokusebenza kwenjini ye-LB170F

Njengenjini yepetroli enezibetho ezine, i-LB170F isebenza kumjikelo wezibetho ezine: intake, icompression, amandla, kunye ne-exhaust.

(1) Istroke yokungenisa

Ekuqaleni kwe-intake stroke, i-intake valve ivuliwe kwaye i-exhaust valve ivaliwe. I-crankshaft iyajikeleza, iqhuba i-piston ukuba isuke kwiziko eliphezulu elifileyo iye kwiziko elisezantsi elifileyo ngokusebenzisa intonga yokudibanisa. Kule ndawo, ivolumu ephezulu ye-piston iyanda kancinci kancinci, kwaye uxinzelelo olungaphakathi kwi-cylinder luyehla kancinci, luvelisa amandla okufunxa i-vacuum afunxa umxube ovuthayo kwi-cylinder ngepayipi yokungenisa kunye ne-intake valve. Xa i-piston ifika kwiziko elisezantsi elifileyo, i-crankshaft ijikeleza isiqingatha sokujika (180°), i-intake valve iyavala, kwaye i-intake stroke iyaphela. Ngexesha lenkqubo yokungenisa, uxinzelelo lwangaphakathi lwe-P ye-cylinder kunye ne-cylinder volume V ziyatshintsha ecaleni kwe-curve ra. Ekupheleni kwe-intake stroke, uxinzelelo lwangaphakathi lwe-cylinder luphantsi kancinci kunoxinzelelo lwangaphandle lomoya.

(2) Uxinzelelo lokubetha

Ekuqaleni kwe-compression stroke, zombini iivalvu zokungenisa kunye nezokukhupha umoya zihlala zivaliwe. I-piston isuka kwiziko elingaphantsi elifileyo iye kwiziko eliphezulu elifileyo. Umthamo wangaphakathi wesilinda uyancipha, uxinzelelo luyanda, kwaye umxube ovuthayo uyacinezelwa. Xa i-piston ifika kwiziko eliphezulu elifileyo, i-crankshaft ijikeleza umjikelo wesiqingatha sesibini (oko kukuthi, ukujikeleza okupheleleyo kwe-360°), kwaye i-compression stroke iyaphela. Ekupheleni kwe-compression stroke, uxinzelelo lwegesi kwigumbi lokutsha lufikelela kwi-0.6-1.5MPa kwaye ubushushu bufikelela kwi-600-700K.

(3) Ukubetha ngamandla

I-power stroke linqanaba elibalulekileyo lokuba injini ivelise umbane. Ngasekupheleni kwe-compression stroke, inkqubo yokutsha ivelisa i-spark yombane ene-voltage ephezulu nge-spark plug ukuze itshise umxube ovuthayo kwigumbi lokutsha (ii-intake kunye nee-exhaust valves zihlala zivaliwe). Igesi exutyiweyo itsha ngokukhawuleza, kwaye ubushushu kunye noxinzelelo lwegesi kwi-cylinder zinyuka kakhulu. Kufuphi ne-dead center ephezulu, ubushushu bunokufikelela kwi-2200 ukuya kwi-2800K kwaye uxinzelelo lunokufikelela kwi-3 ukuya kwi-6MPa. Igesi enobushushu obuphezulu kunye noxinzelelo oluphezulu oluveliswa kukutsha ityhala i-piston ezantsi, kwaye umbane udluliselwa kwi-crankshaft ngentonga yokudibanisa, ngaloo ndlela iqhuba izixhobo zoomatshini.

(4) Uxinzelelo lokukhupha umoya

Ekuqaleni kwe-exhaust stroke, ivalvu yokukhupha umoya ivuliwe ngelixa ivalvu yokungenisa umoya ivaliwe. Ipiston isuka kwiziko elingaphantsi elifileyo iye kwiziko eliphezulu elifileyo, ikhupha igesi yokukhupha umoya emva kokutsha kwi-cylinder. Xa ipiston ifika kwiziko eliphezulu elifileyo, i-crankshaft ijikeleza kwisiqingatha sesithathu somjikelo (oko kukuthi, ukujikeleza okupheleleyo kwe-540°), kwaye i-exhaust stroke iyaphela. Emva koko, ivalvu yokungenisa umoya ivuleka kwakhona kwaye umjikelo olandelayo wokusebenza uqala.

(2) Ukugcinwa rhoqo

Tshintsha ioyile yenjini kunye nesihluzi: Kucetyiswa ukuba utshintshe ioyile yenjini kunye nesihluzi seoyile rhoqo emva kweeyure ezingama-50 zokusebenza okanye rhoqo ngekota ukuqinisekisa ukuthambisa kakuhle iindawo zangaphakathi zenjini.
Jonga iiplagi zespark: Hlola rhoqo isithuba se-electrode kunye ne-carbon deposits zee-spark plugs. Zitshintshe ii-spark plugs ukuba kuyimfuneko ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yokutsha.
Jonga ukuvuleka kwevalvu: Jonga rhoqo indawo evulekileyo yevalvu ukuqinisekisa ukuba ingaphakathi koluhlu oluchaziweyo, nto leyo eqinisekisa ukusebenza kakuhle kwenjini ekungeneni nasekukhupheni umbane.

(3) Amanyathelo okhuseleko

Kuphephe ukusebenza ixesha elide ngomthwalo omninzi: Nangona injini ye-LB170F inamandla aphezulu, ngexesha lokusebenza ixesha elide lomthwalo omninzi, kuyimfuneko ukuthatha ikhefu elifanelekileyo ukuthintela injini ekutshiseni kakhulu.
Nika ingqalelo ekupholiseni injini: Isiphumo sokupholisa seenjini ezipholiswe ngumoya sichaphazeleka kakhulu bubushushu obuphakathi kunye nokuhamba komoya. Xa zisetyenziswa kwiindawo ezinobushushu obuphezulu okanye kwiindawo ezinomoya ophantsi, kufuneka kuqwalaselwe ngokukodwa ukusasazwa kobushushu kwenjini.
