Ezindaweni eziningi, izinga lokushisa liphansi kakhulu ebusika, futhi abanikazi bezimoto abaningi baye babhekana nehlazo lokuba injini iqhwa futhi iqhekeke. Lesi simo sivame ukwenzeka lapho injini ebandayo iqalwa. Uyazi ukuthi injini iyaba yiqhwa futhi iqhekeke ibe ngamadigri ambalwa ngaphansi kweziro?
Ukuqandisa kwenjini nokuqhekeka kuvame ukuvama ukuba ngaphansi kokususa amadigri ayishumi, kodwa hhayi lapho izinga lokushisa lifinyelela ngaphansi kuka -10, ibhulokhi yenjini izoba yiqhwa futhi iqhekeke.

Kudingeka izimo ezimbili zokuqandisa injini nokuqhekeka, enye iwukuqala okubandayo, kanti enye ayinayo i-antifreeze noma isinqandi-qhwa esinganele.

Isizathu esenza injini ibe yiqhwa futhi iqhekeke ingoba umthamo woketshezi olunqanda ukuqhwalela uyakhula lapho ubanda epayipini, okubangela ukuthi irediyetha yande futhi iqhekeze futhi imise ibhulokhi ye-cylinder yenjini noma ikhanda lesilinda. Ngesikhathi esifanayo, lapho injini ebandayo iqalwa, isiqandisi esisenjinini asikwazi ukuzungeza epayipini ukuze sikhiphe ukushisa ngenxa yokuqhwaza, okungadala umonakalo kalula enjinini.

Indlela yokulungisa ukuqandisa kwenjini nokuqhekeka? Xoxa ngale nkinga ngezingxenye ezincane nezinto zokwakha.
Okokuqala, ake sikhulume ngezinto ezivamile ze-cylinder block. Amasilinda ezimoto ngokuvamile ahlukaniswa abe yinsimbi eyinsimbi ne-cast aluminium. Amasilinda ensimbi angalungiswa. Imifantu emincane ivamise ukushiselwa ize ife ngezinti zokushisela futhi udonga lwesilinda lungenziwa bushelelezi. Uma umzimba we-cylinder uyi-aluminium ephonswe, ingashintshwa kuphela iyonke, futhi i-aluminium yensimbi ayikwazi ukulungiswa.

Zimbili izingxenye zenjini ezijwayele ukubanda futhi ziqhekeke, enye iyisilinda kanti enye iyikhanda le-cylinder.

I-cast iron cylinder block ingalungiswa, kodwa ikhanda le-cylinder alikwazi ukulungiswa nge-welding, kungakhathaliseki ukuthi iyiphi impahla, ingashintshwa kuphela izingxenye ezintsha. Ngenxa yokuthi ikhanda le-cylinder lisetshenziselwa ukubekwa uphawu, amandla okushisela ngemva kokuqandisa nokuqhekeka akude nokufinyelela izinga lokuqala.

Indlela yokuvimbela injini ukuba iqhwa futhi iqhekeke?
1. Miselela isinqanda-qhwa sekhwalithi ephezulu ngenkathi ugcina ileveli yoketshezi endaweni evamile. Ezindaweni lapho izinga lokushisa liphansi kakhulu ebusika, amanzi ahlanzekile akumele asetshenziswe njengesibambiso, futhi kufanele kusetshenziswe into yokupholisa imoto ekhethekile. Iphuzu lokuqandisa le-coolant yemoto lingaphansi kwama-degrees angu-60, angasetshenziswa ezigcawini eziningi;
2. Uma amanzi ahlanzekile asetshenziswa njenge-antifreeze, khona-ke ngemva kokuba ilangabi licishiwe, i-antifreeze outlet kufanele ivulwe ukuze ikhiphe wonke amanzi, bese ugcwalisa amanzi afudumele uma uyisebenzisa;
3. Paka imoto egalaji elingaphansi komhlaba. Izinga lokushisa lomgwaqo ongaphansi komhlaba ngokuvamile liphezulu, futhi i-antifreeze akulula ukuyiqhwa.
