Umutwe wa silinderi nikintu cyingenzi cyubaka moteri. Umwobo nyamukuru wamavuta ni igice cyingenzi cyumutwe wa silinderi. Niba umwobo nyamukuru wamavuta ufite burrs, burrs izahagarika tappet ya hydraulic mugihe amavuta yinjiye mumwobo wa HVA, bikananirana. , Nibishobora gutuma valve yumutwe wa silinderi idashobora gufunga, bigatuma blindingi ibura silinderi. Niyo mpamvu, birakenewe ko nta burrs iguma mu mwobo munini wamavuta.

Impamvu za burrs kumyobo ya peteroli yumutwe:

Igikorwa cyo gucukura amavuta yo gutambutsa amavuta ya silinderi yumutwe wigikorwa cyibanze ni uburyo bwo kunyerera bukozwe nigikoresho cyo gutobora igikoresho gikanda ku kazi. Bitewe nimiterere nuburyo imiterere yamavuta ubwayo, impande, imfuruka, nu mfuruka ku masangano y’ibice bibiri cyangwa byinshi bya peteroli. Impande zizagaragaramo disformasiyo nini ya plastike, drill bit hamwe nakazi kazagira inzira yo gutandukana kumasangano, byoroshye kubyara burrs.

Ingaruka nyamukuru za silindiri umutwe wamavuta burrs ni:

1. Kugira ingaruka ku bipimo by'akazi;
2. Kugira ingaruka cyangwa kubangamira gupima neza ibipimo byakazi;
3. Ibibyimba bigwa mugihe cyo gutunganya cyangwa gutwara, bigira ingaruka ku isuku yibice;
4. Mugihe cyo kwishyiriraho, burr iragwa kandi harikibazo cyumutekano cyo gukata no gukata;
5.Mu gihe cyo gutunganya ibyakurikiyeho, burr igwa igatera igihombo cyigice (igice kibi), gitera igice guseswa;
6. Burr iragwa, burr igwa hagati yigitereko nigitwikirizo cya kamera, bikaviramo kwambara bidasanzwe kumashusho nigitwikiro cyamafoto cyangwa no gufunga kamera;
7. Burr igwa muburyo bwa VVT igatera uburyo bwo guhuzagurika bikananirana;
8. Hindura ingaruka zo gusiga, bityo bigire ingaruka kumikorere ya moteri.
