Izinjini zokugaya zangaphakathi ezisetshenziswa ku-lawn mowers zimbili futhi ezine zinhlangothi. Ukuze abasebenzisi bazi, injini ye-lawnmower enenjini engu-4 ithululelwa ngokwahlukile kuphethiloli. Ngenjini eneziteji ezimbili, kuhlanganiswa ingxube yamafutha ngokufakwa kwamafutha. Ngasikhathi sinye, kunconywa ukwakheka okuhlukile okungenakushintshwa futhi kuhlanganiswe.
Indima kawoyela ezinjini zokuhlanganiswa kwangaphakathi
Amandla adluliswa yi shaft yenjini emishinini ejikelezayo atholakala ngenxa yokwanda okubamba kwamagesi ngesikhathi sokuqhuma egumbini lokuhlangana. Ngenxa yokuhamba kwepiston egumbini lokuhlangana, ukucindezela kwegesi kwenzeka. Lokhu kusho ukuthi uhlelo lusebenza ngesikhala esincane, kuvela i-abrasion ezingxenyeni zokuvuthwa. Igebe eliphakathi kwezingxenye liyenyuka, futhi ukucindezelwa kokucindezela kuyancipha, ingcindezi edingekayo ayifinyelelwanga yokulahla ingxube yomoya.
Ngakho-ke kungaba uma izingxenye zomhlaba zisebenza ngaphandle kokuthambisa. Uwoyela wemoto wabatshisi bezinhlamvu, owenezelwe uphethiloli noma owela ezinhlanganweni zemikhumbi, ufakwa ngefilimu emincane phakathi kwezingxenye, ukuvimbela ukugqabhuka nokuklebhula. Njengoba kungenakwenzeka ngokuphelele ukuqeda ukugqabuka nokuklebhula, uwoyela ukhipha imicroparticles ezikhaleni, ukuze kuvinjelwe kungonakalisi ingaphezulu komhlaba.
Ingxube yamafutha elungisiwe kufanele isetshenziswe amaviki ama-2, igcinwe esitsheni sensimbi noma se-polypropylene. Musa ukugcina ukwakheka kwawo ngophethiloli emabhodleleni epulasitiki. Imikhiqizo yokuwohloka izowela engxenyeni, isotho egumbini lokuhlangana lizonyuka.
Idivayisi 2 no-4 yezinhlobo zomjikelezo yehlukile futhi ngakho-ke ukungaguquguquki kokugcotshiswa nokwengezwayo kuyo kuhlukile. Uhlobo ngalunye lwezindawo ezihlanganisiwe kuzindlela zidinga izinhlobo zokugcoba ezihambelana nesimo sokuhamba kwale node. Uhlobo luni lwamafutha okumele ugcwalise ngalo mower, umenzi uncoma emiyalweni yokusebenzisa.
Awukwazi ukugcwalisa uwoyela, uqondiswe okubizayo, okungcono. Ukusetshenziswa kwezithako kuncike eklasini lobuchwepheshe ezingeni lokugaya kwamayunithi okuphelisa, izimo zokusebenza. Ukwakheka kwengxube evuthayo yezinjini ezinhlangothi-mbili kuya ngokuthi iyiphi indlela yokuthola isisekelo sokuqanjwa kwe-antifriction. Uwoyela wokucheba utshani onenjini enenjini engu-2 unokwakheka okukhethekile. Onke uwoyela ahlukaniswa indlela yokulungiselela:
- amaminerali;
- zokwenziwa;
- okwenziwe ngokwedlule.
Izimfanelo zabo zokuthambisa kanye namandla okuhlala ewuketshezi emazingeni okushisa aphansi kuncike kulokhu. Kepha i-5-15% ekwakhiweni ngakunye ibekelwe izengezo. Lokhu bakha ukwakheka okusebenzayo okuvimbela:
- ukugqwala komhlaba;
- ukuzinza okushisayo;
- ukumelana nokubola;
- ukukhuphuka kwe-alkalinity, ukuvimbela i-oxidation;
- ukuzinzisa ukubukeka.
U-oyela otshaniwe ngotshani osetshenziswa ngenjini engu-4 unezinye izengezo, i-viscosity. Iphinde isebenze ukugeza okuphezulu, kepha akuhlangananga nophethiloli. Amafutha axutshwe, angcolisiwe nezinhlayiya zesikali futhi adinga ukushintshwa njalo ngamahora angama-50 wokusebenza.
Umehluko ekusebenzeni kwezinjini ze-2 ne-4 ezinenjini
Ukuze usebenzise izinjini ezinenjini emibili, kunezindlela ezimbili zokugcoba uhlelo lwe-piston kanye ne-crank mechanism:
- ukwengeza uwoyela kawoyela ku-isilinganiso esiqondile;
- uthele i-oli ngokwahlukana, inhlanganisela iyakhiwa lapho uphethiloli ungena kusilinda.
Esithombeni, ukuhanjiswa kwamafutha nge-plunger pump dispenser kufaka ipayipi lokungena legumbi lokuhlangana.
Uhlelo lwesibili lunekusasa, kuyilapho kusetshenziswa indlela yokuqala engadini - ukulungiswa kwengxube evuthayo. Izinjini ezintsha zithulile, zinomnotho, kepha ziyinkimbinkimbi ngokwengeziwe.
Ukulungiselela ingxube evuthayo, ungasebenzisa itafula kanye ne-dispenser.
Injini enezinhlangothi ezine inethangi likawoyela, elisetshenziselwa ukudala izivikelo ezingxenyeni zokuhlikihla. Kulokhu, uhlelo lokuthambisa luqukethe ipompo, isihlungi sawoyela namashubhu ahlinzeka ukwakheka kuzindawo. Kungasetshenziswa indlela yokuthambisa noma yokugcoba. Esimweni sokuqala, u-oyela uhlinzekwa ohlelweni kusuka ku-crankcase futhi ukusuka lapho uqhutshwe kuwo amashubhu wokuhambisa. Ngamaconsi e-oyili “awomile” aqoqwe kusobho ayaphinda athunyelwa ethangini.
Esithombeni, gcoba isobho elimanzi negrisi eyomile yesobho.
Umehluko ekwakhiweni kwamafutha ezinhlobo ezahlukahlukene zezinjini ubalulekile. Uwoyela wokuchelela utshani onenjini engu-4-kufanele ulondoloze ukwakheka okungapheli isikhathi eside. Ukwakheka kwezinjini ezinenjini emibili ngesikhathi sokuhlanganiswa kufanele kube nokufakwa okumbiwa phansi okunamaminerali ukuze kuvikele ukwakheka kwensipho.
Uma unamafutha anconyiwe, akufanele uzame ukukhethwa kokunye ukwakheka. Uma kungenjalo, khetha onconyelwe amamodeli womjikelezo 2 noma 4. Sebenzisa uphethiloli ngaphezulu komkhiqizo onconyelwayo - ngaphambi kwesikhathi ukuqhubeka nokushintsha ama-valve aphelile, ezinye izinto.
Isici esibalulekile lapho ukhetha isithako sokuzivikela kungukushisa kwaso okusebenzayo. Isengezo kumele simelane nokushisa, kepha hhayi ukuqina ngamazinga okushisa aphansi. Ngakho-ke, kumshini ngamunye, ngokuya ngezimo zokusebenza, kukhona uhlobo lwamafutha.
Ukwehluka okuyisisekelo phakathi kwezinqubo zokushisa zangaphakathi zomsebenzisi
Yimuphi uhlelo lomlilo olusebenza kangcono, 2 au 4 stroke? Ungamqonda kanjani umsebenzisi futhi uthenge indlela engcono kakhulu? Ama-trimmers kaphethiloli kanye nama-motokos anenjini engu-4-ayitholakali athengiswa. Ukushaywa kabili kube lula kakhulu ngakho-ke i-trimmer inesisindo esincane futhi owesifazane angakwazi ukuyilawula. Kepha kukhona izinjini ezinenjini emibili ezimotweni ezinamasondo amane. Eminye umehluko:
- izindlela ezahlukene zokusebenzisa amafutha;
- Ubungani bemvelo buphakeme kunjini enezitezi ezi-4, futhi bunomsindo omncane;
- kulula ukulungisa nokulungisa injini ye-2 stroke;
- Izinsizakusebenza ezinezimoto ezi-4 zinde, kepha zinesondlo esinzima ngokwengeziwe ngenxa yezinguquko kawoyela kumshini wotshani;
- ama-motor ane-stroke amabili alula futhi ashibhile.
Injini enezinhlamvu ezi-2 esetshenziswe ku-lawnmower iphansi kakhulu ezinkombeni eziningi zezobuchwepheshe ekushayweni kwe-4. Ngokuhlinzekwa okuhlukile kaphethiloli ne-oyili ukuze kusetshenziswe kahle nezinye izinkomba, kungcono kakhulu kwizimoto ezikhanyayo. Ngaphezu kwalokho, ukugcwaliswa kukawoyela okuhlukile kusindisa izindleko zento ebizayo izikhathi ezine.
Esithombeni, isimo senjini esasebenza ngaphandle kokushintsha uwoyela isikhathi eside.
Injini enamathambo amane inohlelo oluyinkimbinkimbi lokuthambisa, futhi ngaphezu kwalokho kuyadingeka ukusebenzisa izindlela zokuhlanza uketshezi ezijikelezayo. Kufakwa isihlungi ohlelweni lwamafutha oluvimbela ukuvalwa kwamapayipi kanye nokumpompa ngezinga nokunye okutholakalayo. Njengoba kungcola, le ngxenye iyathathelwa indawo.
Ungawaguqula kanjani i-oli enjini enezilonda ezi-4
Umenzi kwimiyalo yokusebenza unikeza isheduli yokulondolozwa kwezindlela noku-oda kokukhiqizwa. Ukusebenza kahle kwamalambu kuyancipha ngemuva kokusebenza amahora angama-50. Ngakho-ke, ushintsho lwamafutha luyadingeka. Ekusetshenzisweni kwasekhaya okwesikhathi sonyaka, lesi sikhathi sokusebenzisa izinto ngeke sithayishwe, futhi isihlungi kufanele sihlanzwe, u-oyela kumele afakwe esikhundleni sokulondolozwa. Ngaphambi kokushintsha uwoyela ku-mower, kuyadingeka ukukhuphula uketshezi lwamanzi, qala injini bese uvumele uhlelo ukufudumala.
Kuyadingeka ukusula ipulaki lokugcwalisa uwoyela ethangini bese usebenzisa idivaysi yokukhetha uketshezi ngaphansi kwe-vacuum.
Ukuze wenze lokhu, yenza i-nozzle bese ukhipha izimayini esitsheni esilungiselelwe. Kepha ngasikhathi sinye, ingxenye encane, efinyelela ku-100 ml, isahlala ku-crankcase futhi ikhipha kusuka kusihlungi. Le nsalela kumele ilahlwe ngokudonsa uketshezi cishe imizuzu emi-5 ngokusebenzisa umgodi. Shintsha noma thinta ukuhlunga ohlelweni ngasikhathi sinye. Ngemuva kokugcwalisa igrisi entsha, uhlola izinga nge-dipstick. Imvamisa, uwoyela wemoto ufakwa epulasitiki emnyama ye-opaque ukuze ingaboli ekukhanyeni. Umthamo odingekayo ngu-500-600 ml.
