Indlela ulungise nokusulwa umphini ku isithuthuthu?

Abanikazi Iningi Scooters nge ezine-unhlangothi izinjini bazi ukuthi imvume umphini kumele kushintshwe. Kodwa nalwazi nokungazi bamshaya ukunakwa ezidingekayo kule nqubo. Futhi ukuzonda ngesizathu esihle. Ngokulungisa ama-valve ku injini yakho, ngeke nje ngcono ukuzinza imisebenzi yayo, kodwa futhi bandise nokuphila inkonzo. Kungase kubonakale ukuthi amafraktjhini ambalwa amamilimitha angu kungukuthi okuningi kuthinta ukusebenza kwe-scooter.

Nokho, umkhuba ubonisa ukuthi kukhona izikhala ezincane kakhulu noma inkulu kakhulu valve ukusheshisa injini bafake izikhathi eziningana, nokusiza ukunciphisa isikhathi somsebenzi wakhe ngezinye izikhathi. Ake uphendule umbuzo kungani lokhu okwenzekayo.

Imizwa kubhekwa njengento evamile umphini nokusulwa ngoba Scooters (injini nomthamo 50-100 cm3) mayelana 0.05 mm. Lokhu value kuyinto kokubili qeda kanye valve engayitholi okufanayo. Nokho, uma luyanda ke injini iqala engqongqoza. Latimviwa at ukusebenza injini kokungenzi lutho ezifana wezwa njengoba tarahtenie umshini wokuthunga.

Kodwa izinkinga akukho kule. Ukwandiswa ezishisayo umphini nokusulwa azixoshe isikhathi valve. Ngakho-ke, ngokungeza ijubane motor incipha Rod isikuta, kwandisa petrol kanye bafake mshini valve.

Lapho nokusulwa umphini ngaphezu kudingekile ngenkathi injini sisesimweni esibi saba sibi nakakhulu. Phela, kukhona ukulahleka kokucindezelwa kusukela lokuthi izikhala, Ukushisa, abe ngisho ezincane, kokuvula valve. Negesi ukufohla kwenzeka futhi ukulahlekelwa amandla. Kungase kube valve ezishile-ngokusebenzisa noma sehhashi.

Ngemva kwakho konke lokhu isikuta enkingeni eyeka hambisa ezinhle. Walahlekelwa amandla amnyama ngu umule amakhandlela. Ngakho-ke, akukho lutho kwesokunxele ukwenza, indlela esikhundleni valve noma ngisho lonke ikhanda lonke.

Better kanye ayinkulungwane amakhilomitha ukulungisa nokusulwa umphini ku isithuthuthu kuka ukuthenga izingxenye ezintsha. Ukuze wenze lokhu (isibonelo, u-Alfa no-Delta), zidinga amathuluzi anjalo:

- iqoqo okhiye;

- iqoqo iphenya;

- impintshisi.
Kodwa khumbula ukuthi valve ukulawula lapho injini abandayo (lapho izinga lokushisa ngaphansi kwezingaqhwa, khona-ke ukufuthelana kancane). Inqubo zokusebenza kuyehla kube imisebenzi elandelayo:

- screwing out amakhandlela.

- Ukufakwa piston at TDC (ekupheleni unhlangothi kokucindezelwa), kukhishwa la ma-valve. Ukuze ukuhlole, uyasikrufulula ipulaki ekhaveni izindlu kanye cranking injini, qiniseka ukuthi uphawu "T" ncamashi phakathi the dweba. Usebenzisa isikrufu futhi uyasikrufulula ipulaki ngokuvula screw ijoka, ukwenza ukulungiswa. Lo msebenzi kumele kwenziwe ngokucophelela ukuze kungabi bikho ukulimala screw, okuyinto evame plastic. Kala igebe uphenyo, okuyinto ngesikhathi ukushuba 0.04 mm okufanele idlule ngokukhululekile, nalapho kungekho prolazili 0,06. Ihlole 0.05 mm kufanele ufake kanzima.

- kokuqina inhlansi plugs, futhi emuva besezihlalweni zabo.

Yilokho. Njengoba ubona, akukho izimfihlo ekhethekile lapha. Manje ungaqala futhi kulungele injini. Lapho kushintshwe ngendlela efanele, ngokushesha ukukhomba ngu indlebe, njengoba buthule njengoba eqala ukusebenza isithuthuthu yakho futhi kumnandi kanjani iya.
