Lapho injini ye-VAZ igoba khona i-valve

Abanikazi bezimoto abaningi banesithakazelo kulo mbuzo, lapho izimoto, noma kunalokho izinjini, i-valve igoba lapho ibhande lesikhathi liphuka? Ukukhumbula lezi zinguquko zenjini akunzima kangako.

Ake siqale ngokulandelana. Lapho kuvela izimoto zokuqala ze-VAZ 2110, izinjini ezinama-valve angu-8 ezinevolumu ye-1,5 bese zifakwa kuwo umthamo wamalitha angu-1,6. Kulezi zinjini, uma kwenzeka kuphuka ibhande, i-valve ayizange igobe, ngoba ama-piston awazange ahlangane nama-valve.

Ngemva kwesikhashana, emndenini weshumi we-VAZ kwavela imoto ye-VAZ 2112 enenjini engu-16-valve engu-1,5-litre. Kulapho kwaqala khona izinkinga kubanikazi bokuqala balezi zimoto. I-design ye-injini ishintshile kakhulu, ngenxa yekhanda le-valve engu-16, futhi amandla enjini anjalo akhuphuke ukusuka ku-76 horsepower kuya ku-92 hp. Kodwa ngaphezu kwezinzuzo zenjini enjalo, kwakukhona nezinkinga. Okungukuthi, lapho ibhande lesikhathi liphuka ezinjini ezinjalo, ama-piston ahlangana nama-valve, ngenxa yalokho i-valve igobile. Futhi ngemva kwakho konke lokhu, abanikazi bezimoto ezinezinjini ezinjalo babelindele ukulungiswa okubizayo, okwakuzodingeka bachithe okungenani ama-ruble angu-10 000.

Isizathu sokuphuka okunjengama-valve agobile kusekuklanyweni kwenjini engu-1,5 16-valve: kuma-motor anjalo, ama-pistons awanawo ama-valves, ngenxa yalokho, lapho ibhande liphuka, ama-piston ashaya ama-valve nama-valve agobile.

Ngemva kwesikhashana, izimoto ezifanayo ze-VAZ 2112 zaqala ukufakwa izinjini ezintsha ezingu-16 ezinevolumu yamalitha angu-1,6. Ukwakhiwa kwezinjini ezinjalo kwakungehluke kakhulu kunangaphambili ngevolumu yamalitha angu-1,5, kodwa kunomehluko owodwa obalulekile. Enjinini entsha, ama-piston asevele efakwe nama-grooves, ngakho-ke, uma ibhande lesikhathi liphuka, ama-pistons ngeke esahlangana nama-valve, okusho ukuthi ukulungiswa okubizayo kungagwenywa.

Sekudlule iminyaka eminingana, futhi abashayeli bezimoto ezifuywayo sebejwayele ukuthi izinjini ezinama-valve angu-16 sezinokwethenjelwa, ngomqondo ongokomfanekiso, zilimele-ziphephile ngokuphathelene nama-valve. Kodwa imoto entsha yaphuma emgqeni womhlangano, omunye angase athi i-Lada Priora ebuyekeziwe eyishumi. Bonke abanikazi bacabanga ukuthi njengoba iPriors inenjini engu-16 litre 1,6 valve, ivalvu ngeke igobe. Kodwa njengoba umkhuba ubonisile, ezimweni zebhande lesikhathi eliphukile ku-Lada Priore, ama-valve ahlangana nama-pistons futhi awagobe. Futhi ukulungiswa kwezinjini ezinjalo kuzobiza kakhulu kunezinjini "zeshumi nambili". Yiqiniso, amathuba okuthi ibhande lizophuka ku-Prior aliphakeme, ngoba ibhande lesikhathi licishe libe kabili ububanzi kunama-injini "yeshumi nambili". Kodwa, uma uhlangabezana nebhande elinesici, khona-ke amathuba okuphuka kwebhande akhula kakhulu futhi akunakwenzeka ukwazi ukuthi kwenzekani ikhefu.

Futhi, ezinjinini ezintsha ezifakwe ku-Lada Kalina: 1,4 16-valve, kunenkinga efanayo, lapho ibhande liphuka, ukulungiswa okubizayo akunakugwenywa. Ngakho-ke, udinga ukuqapha njalo isimo sebhande lesikhathi.

Akumele futhi uthembele ekutheni uma unenjini ephephile, amavalvu enjini enjalo ngeke agobe. Uma kukhona ungqimba olukhulu lwe-carbon deposits kuma-piston nama-valve, khona-ke kwezinye izimo ukugoba kwe-valve kungenzeka ezinjinini ezinjalo. Futhi, udinga njalo ukuqapha isimo sebhande lesikhathi, hlola ama-chips, imifantu, izintambo ezivelayo kanye ne-delamination. Zonke lezi zimpawu zibonisa ukuthi udinga ukushintsha ibhande ngokushesha. Kungcono ukusebenzisa ama-ruble angu-1500 kunokuba unikeze okungenani izikhathi eziyishumi ngaphezulu. Futhi ungakhohlwa ngokushintsha ama-roller, kuhle ukuwashintsha okungenani njalo ngemva kokushintshwa kwebhande lesikhathi sesibili.
