Izizathu kunye nezisombululo zokukhupha umsi ongaqhelekanga weenjini zedizili zeCaterpillar (umsi omnyama)

2022-04-06

Izizathu kunye nokupheliswa komsi omnyama Lo mcimbi ubangelwa ukutshiswa okungaphelelanga kwepetroli. Xa kukhutshwa umsi omnyama, ngokufuthi ukhatshwa kukuhla kwamandla enjini, ubushushu obuphakamileyo bokuphuma komsi, nobushushu obuphakamileyo bamanzi, nto leyo eya kukhokelela ekugugileni nasekukrazukeni kwamalungu enjini kuze kunciphise ubomi benjini.

Izizathu zalo mcimbi (zininzi izizathu zokutsha okungaphelelanga) kunye neendlela zokuphelisa ngolu hlobo lulandelayo:

1) Ukukhupha uxinzelelo lwasemva kuphezulu kakhulu okanye umbhobho wokukhupha uvaliwe. Le meko iya kubangela ukungena komoya okwaneleyo, ngaloo ndlela kuchaphazela umlinganiselo wokuxuba amafutha emoyeni, okubangela ukuba kubekho ifutha eninzi. Le meko iyenzeka: Okokuqala, ukugoba kombhobho wokukhupha, ngokukodwa ukugoba kwe-90 ° kuninzi kakhulu, okufuneka kuncitshiswe; okwesibini kukuba ingaphakathi le-muffler livalwe yi-soot eninzi kwaye kufuneka isuswe.

2) Ukungena komoya okwaneleyo okanye ukuvalelwa kombhobho wokungenisa. Ukuze ufumane isizathu, kufuneka kuqhutywe ezi zitshekisho zilandelayo: okokuqala, ingaba i-air filter ivaliwe; okwesibini, ingaba umbhobho wokungena uvuza (ukuba oku kuyenzeka, injini iya kuhamba kunye nekhwelo elibukhali ngenxa yokunyuka komthwalo); okwesithathu Ingaba i-turbocharger yonakele, khangela ukuba ii-blades zevili legesi ephumayo kunye nevili le-supercharger zonakele kwaye ukuba ukujikeleza kugudileyo kwaye kuguquguqukayo; eyesine kukuba i-intercooler ivaliwe.

3) Ukukhutshwa kwevalve ayilungiswanga ngokuchanekileyo, kwaye umgca wokutywina wevalve awuhambelani kakuhle. Ukucocwa kwevalvu, imithombo yevalvu, kunye nezitywina zevalvu kufuneka zijongwe.

I-4) Ukunikezelwa kweoli ye-cylinder nganye yepompo ye-oyile ephezulu ayilingani okanye inkulu kakhulu. Unikezelo lwe-oyile olungalinganiyo luya kubangela isantya esingazinzanga kunye nomsi omnyama ophazamisayo. Kufuneka ilungiswe ukuze ilungelelanise okanye ibe phakathi koluhlu oluchaziweyo.

5) Ukuba inaliti yamafutha ishiywe lixesha, i-angle yangaphambili yesitofu samafutha kufuneka ilungiswe.

6) Ukuba i-fuel injector ayisebenzi kakuhle okanye yonakaliswe, kufuneka isuswe ukucoca nokuhlolwa.

7) Ukukhethwa kwemodeli ye-injector ayilunganga. Iinjini zesantya esiphezulu ezithunyelwa kumazwe angaphandle zineemfuno ezingqongqo kwii-injection ezikhethiweyo (i-injection aperture, inani lemingxuma, i-injection angle). (Xa amandla okuphuma, isantya, njl. njl.), iimodeli ze-injector ezifunekayo ziyahluka. Ukuba ukhetho alulunganga, uhlobo oluchanekileyo lwesitofu sokufutha kufuneka kutshintshwe.

I-8) Umgangatho we-diesel umpofu okanye ibakala alilungile. Injini ye-diesel ephuma kumazwe angaphandle enesantya esiphezulu exhotywe ngegumbi lokutshisa inaliti ye-multi-hole injector ineemfuno ezingqongqo kumgangatho kunye nomgangatho wedizili ngenxa yokuvula okuncinci kunye nokuchaneka okuphezulu kwe-injector. I-injini ayisebenzi kakuhle. Ngoko ke, ioli ye-diesel ecocekileyo nefanelekileyo kufuneka isetyenziswe. Kunconywa ukusebenzisa i-No. 0 okanye +10 ehlotyeni, -10 okanye -20 ebusika, kunye -35 kwiindawo ezibandayo ezibandayo.

I-9) I-cylinder liner kunye ne-piston components zigugile kakhulu. Xa oku kusenzeka, umsesane wepiston awuvalwanga ngokuqinileyo, kwaye uxinzelelo lomoya kwi-cylinder lwehla kakhulu, nto leyo ebangela ukuba i-oyile yedizili ingatshi ngokupheleleyo kwaye ikhuphe umsi omnyama, kwaye amandla e-injini ehla kakhulu. Kwiimeko ezinzima, injini iya kuzicima ngokuzenzekelayo xa ilayishiwe. Iindawo zokunxiba kufuneka zitshintshwe.
