Izindlu zezimoto kanye nezinkinga ngokujikeleza kwayo. Indlela yokunquma ukuthi inkinga ikuyo?

Akuvamile kakhulu ukuthi iphutha lokukhiqiza libangele ukuthi igobolondo elithwalayo lijikeleze kumotho. Ngokuvamile lokhu kungenxa yobudedengu emsebenzini. Izindlu zenjini zenzelwe ukugcwala okukhulu okubangelwa ukusebenza kwenduku yokuxhuma nepiston. Nokho, ngenxa yokusetshenziswa kakhulu, ingase igoqe. Yini okufanele uyenze kuleli cala? Kubiza malini ukushintshwa kwe-crankcase yenjini? Konke lokhu (nokuningi) uzofunda ngokufunda isihloko sethu!

Injini enegobolondo - kuyini?

Lokhu kungenye yezingxenye zama-plain bearings. Ukufakwa kwenduku yokuxhuma kukhona ku-shank nekhanda layo. Ukuma kwayo kufana nocezwana. Inendawo eyisicaba, okumele ixhumane nephuzu lokunamathisela entweni yokuxhuma. Ingaphezulu lalezi zingxenye linemifantu yokuqinisekisa ukunyakaza nokusatshalaliswa okunembile kwamafutha enjini. Ama-Crankshaft liners alingana ohlangothini ngalunye lwesokhethi induku yokuxhumaefakwe ku-shaft.

Ukujikeleza kwe-acetabulum - kungani lokhu kwenzeka?

Igobolondo lenjini linesibopho sokunciphisa ukungqubuzana phakathi kwezinto zohlelo lwe-piston-crank. Nokho, idinga uwoyela wenjini ukuze isebenze kahle. Yisiphi isizathu esiyinhloko sokwehluleka ukuthwala nokusonteka kwalesi sici? Lokhu ikakhulukazi ukunganakwa kwesikhawu sikawoyela. Ukuntuleka kwamafutha kuyiresiphi yokubamba nokujikeleza i-acetabulum. Uma kwenzeka inkinga, umshayeli angakwazi ukubona izimpawu ngaphandle kokukhipha ingxenye engaphansi yenjini.

Inkomishi ephendukile - izimpawu 

Izihlahla ezigugile, ezisontekile ngenxa yokungqubuzana, ziqala ukungqongqoza ngokucace kakhulu lapho ipiston isebenza. Lokhu kungafaniswa nokushaya isando sensimbi kwenye into eyinsimbi. Umsindo awukwazi ukudideka nanoma yimuphi omunye. Ezikhathini eziningi, uzozwa izihlahla ezilimele ngesivinini esikhulu senjini, kodwa ezimweni eziningi uzobona ukungqongqoza okuhlukile kusukela ngesikhathi uqala ukushayela.

Igobolondo elimele elimele - imiphumela yokushayela ngokuphuka

Ngemva kokuhlonza inkinga ngezindlu zenjini, akufanele uqhubeke. Kungani? Ukuntuleka kokuthambisa kujenali ye-shaft kanye nokuzungezisa kwegobolondo elithwele kubangela ukuguga endaweni ye-crankshaft endaweni ebucayi. Ikesi lenjini elimele lingaphinde libhujiswe umsebenzi futhi likhulule amafayili ensimbi ku-lubricant. Uma i-sawdust ingena kwezinye izingxenye zenjini, izoklwebha phezulu noma ivale amaphaseji kawoyela.

Ungawaxilonga kanjani ama-crankshaft bearings awonakele?

Izindlela ezincane kakhulu zokuxilonga ama-shaft bearings yilezi:

• ukuvala amakhoyili okushisa lapho iyunithi isebenza;
• ukujikeleza kwe-shaft kanye nokuthinta ingaphezulu lepiston ngento eqinile (enganwayi).

Indlela yokuqala idla isikhathi esincane kakhulu futhi awudingi ukuhlaziya izakhi eziningi. Uma usola ukuthi ikesi lenjini liphendukile, qala umshini bese unqamula amakhoyili kusilinda esisodwa ngesikhathi. Khumbula ukukwenza ngokucophelela. Yiqiniso, kule silinda izohluleka injini engenanhlansi, kodwa uma usuyitholile elungile, ukungqongqoza okukhona kuzokwehla ngokuphawulekayo.

Kanjani futhi ukuhlola uma inkinga in the motor izindlu?

Ungazama le ndlela elandelayo ezinjinini zikadizili lapho indlela yangaphambilini ibingeke isebenze. Izinkomishi ezijikelezayo zinikeza izimpawu zokuthepha, kodwa futhi zandise isikhala phakathi konyawo nengxenye ephukile. Ungahlola kanjani? Udinga ukuthatha into ende futhi eqinile (njenge-screwdriver) futhi uphendule i-shaft kuze kube yilapho i-piston iphuma ku-TDC. Bese ucindezela i-screwdriver ngokuqinile phezulu kwepiston. Uma uzwa futhi uzwa ukuchofoza okuhlukile, khona-ke igobolondo lenjini kule rodi yokuxhuma lihlulekile.

Ukushintsha i-bearing enjinini - izindleko

Ukuze ususe ukungasebenzi kahle, kuzodingeka wenze ukulungiswa okukhulu noma ukushintshwa kokuvimbela injini. Udinga ukuqaqa ingxenye engezansi yebhulokhi futhi ulahle ijenali ye-crankshaft yenjini, ama-bearings kanye nenduku ethile yokuxhuma. Isokhethi ephendukile ayidingi nje ukufaka esikhundleni sekhithi entsha, kodwa futhi nokuhlola ezinye izici zokuxhumana. Ezimweni eziningi, i-crankshaft kanye nenduku yokuxhuma kufanele icushwe kabusha umakhenikha. Lena inguqulo enethemba, ngoba ezimweni ezimbi kakhulu injini block ingahluleka. Ikhava yemoto enesici izoholela ekulungisweni noma ekushintshweni kwedrayivu.

Engine izindlu - indlela yokugwema umonakalo

Khumbula ukuthi lolu hlobo lokwehluleka aluvamile ukuba ngenxa yesici sokukhiqiza. Okuhlukile yiyunithi engu-1.9 dCi yakwaRenault. I-bearing ekude kakhulu nepompo kawoyela yayibhajwe kuyo ngenxa yokuntuleka kokugcotshwa. Ukuze ugweme umonakalo onjalo, shintsha uwoyela njalo ngezikhathi ezifanele futhi usebenzise kuphela amafutha anconyiwe enjini yakho.

I-injini yezindlu iyisici esincane, kodwa esibaluleke kakhulu ekusebenzeni kahle kweyunithi yamandla. Ukuze ungangenisi izindleko ezinkulu zokushintsha injini yonke, nakekela izinguquko ezivamile zikawoyela, futhi uma kunezimpawu ezishaqisayo, ungakubukeli phansi ukungqongqoza.
