Kwiindawo ezininzi, iqondo lobushushu liphantsi kakhulu ebusika, yaye abanini beemoto abaninzi baye bafumana iintloni zokukhenkceka nokuqhekeka kwenjini. Le meko iyenzeka kakhulu xa injini ebandayo iqaliswa. Ngaba uyazi ukuba i-injini iyaba ngumkhenkce kwaye iqhekeke ukuya kumaqondo ambalwa ngaphantsi kwe-zero?
Ukukhenkceza kwe-injini kunye nokuqhekeka ngokuqhelekileyo kuxhaphake ngaphantsi kwe-minus degrees ezilishumi, kodwa kungekhona xa ubushushu bufika ngaphantsi kwe-10, ibhloko ye-injini iya kukhenkceka kwaye iqhekeke.

Kufuneka iimeko ezimbini zokukhenkceza kunye nokuqhekeka kwe-injini, enye kukuqala okubandayo, kwaye enye ayinayo i-antifreeze okanye i-antifreeze eyaneleyo.

Isizathu sokuba i-injini ibe ngumkhenkce kwaye iqhekeke kungenxa yokuba umthamo wolwelo olunqanda ukukhenkceka uyakhula xa usiba ngumkhenkce kumbhobho, nto leyo ebangela ukuba iradiyetha yande kwaye iqhekeze kwaye imkhenkce ibhlokhi yesilinda se-injini okanye intloko yesilinda. Kwangaxeshanye, xa i-injini ebandayo iqaliswa, isikhenkcezisi esikwi-injini asikwazi ukujikeleza kumbhobho ukuze sikhuphe ubushushu ngenxa ye-icing, enokwenza lula umonakalo kwi-injini.

Indlela yokulungisa i-injini yokukhenkceza kunye nokuqhekeka? Xoxa ngale ngxaki ngamacandelwana kunye nemathiriyeli.
Okokuqala, makhe sithethe ngezinto eziqhelekileyo zebhloko yesilinda. Iisilinda zemoto zihlulwe ngokubanzi zibe yintsimbi kunye ne-aluminium. Iisilinda zentsimbi zinokulungiswa. Iintanda ezincinci zidityaniswa zife ngokudityaniswa kweentonga ze-welding kwaye udonga lwesilinda lunokugudiswa. Ukuba umzimba we-cylinder uphoswe nge-aluminium, unokutshintshwa kuphela ngokupheleleyo, kwaye i-aluminium ephosiweyo ayikwazi ukulungiswa.

Kukho iinxalenye ezimbini ze-injini ezithanda ukuba ngumkhenkce kunye nokuqhekeka, enye yibhloko yesilinda kwaye enye yintloko ye-cylinder.

I-block ye-cylinder block inokulungiswa, kodwa intloko ye-cylinder ayikwazi ukulungiswa nge-welding, kungakhathaliseki ukuba yintoni na into, inokutshintshwa kuphela ngamacandelo amatsha. Ngenxa yokuba intloko yesilinda isetyenziselwa ukutywinwa, amandla e-welding emva kokukhenkceza kunye nokuqhekeka kukude nokufikelela kumgangatho wokuqala.

Ukuthintela njani ukuba injini ingabi ngumkhenkce kwaye iqhekeke?
1. Faka indawo ye-antifreeze ephezulu ngelixa ugcina umgangatho wolwelo kwindawo eqhelekileyo. Kwiindawo apho amaqondo obushushu aphantsi kakhulu ebusika, amanzi acwengileyo akufunekanga asetyenziswe njengesipholisi, kwaye kufuneka kusetyenziswe into yokupholisa imoto ekhethekileyo. Indawo yokukhenkceza yokupholisa imoto ingaphantsi kwe-60 degrees, enokuthi isetyenziswe kwiindawo ezininzi;
2. Ukuba amanzi ahlambulukileyo asetyenziswa njenge-antifreeze, ngoko emva kokuba ilangatye licinywe, i-antifreeze outlet kufuneka ivulwe ukuze ikhuphe onke amanzi, uze ugcwalise ngamanzi afudumele xa usebenzisa;
3. Paka isithuthi kwigaraji engaphantsi komhlaba. Amaqondo obushushu endlela ephantsi komhlaba adla ngokuba phezulu, kwaye isithinteli sokukhenkceza akulula ukuba ngumkhenkce.
