Kwiminyaka yakutshanje, ishishini lombane laseTshayina liye lavela inani elikhulu lemveliso, inqanaba lemveliso, umgangatho olungileyo, ubugcisa obuphambili kunye namashishini ezixhobo.Nangona kunjalo, akukho mntu unesabelo esiphezulu kwimarike yasekhaya.Iinjini ezincinci kunye neziphakathi azikabikho impembelelo yamazwe ngamazwe ye-brand.Ishishini leemoto kufuneka lidityaniswe ngokungxamisekileyo, ukusinda kwabanamandla, okuye kwaba yindlela yophuhliso loshishino lweemoto.Iingcali zabonisa ukuba nangona ishishini leemoto lishishini elidala lemveli, kodwa zonke iindlela zokuphila ezixhasa iimoto zibalulekile.Ngaphezu koko, amanye amashishini amakhulu ombane agubungela indawo enkulu, ebekwe kwindawo elungileyo, emva kokudityaniswa, iya kuzisa umfumani izibonelelo ezityebileyo kunye nezibonelelo zemali.

Umgaqo-nkqubo wokusingqongileyo

Hlela Ilizwi

Ukuze kuphunyezwe "iSicwangciso seMinyaka emiHlanu ye-12" yeBhunga likarhulumente, iimbono zokuKhawulezisa uPhuhliso loLondolozo lwaMandla kunye noShishino loKhuseleko lokusiNgqongileyo, kunye neNgxelo yoHlalutyo malunga noQoqosho kunye noTshintsho kunye noPhuculo lweMveliso kunye neMfuno yokuThengisa yaseChina. Ishishini lokuVelisa iiMoto zoMbane, likhokela imveliso kunye nokukhuthaza okonga amandla oomatshini kunye nezixhobo zombane (iimveliso), ukudibanisa owona msebenzi wokonga amandla kunye nokunciphisa ukukhutshwa kwemveliso kushishino kunye nonxibelelwano, kwaye kuyacetyiswa, uphononongo lweengcali kunye nopapasho ngamasebe anobuchule. yoshishino neteknoloji yolwazi kunye namashishini anxulumeneyo kwiindawo ezahlukeneyo.I-Catalogue ihlanganisa iimodeli ezingama-344 kwiindidi ezili-9.Phakathi kwabo, iimodeli ze-transformers ezingama-96, iimodeli zombane zeemodeli ezingama-59, iibhoyila zoshishino ezingama-21, iimodeli ze-welding ezingama-77, iimodeli zefriji ezingama-43, ii-compressors ezingama-27 zeemodeli zeemveliso, umatshini weplastiki 5 imifuziselo, imodeli ye-13 fan, unyango lobushushu 3 imifuziselo.

Uluhlu lusebenza iminyaka emithathu ukusuka kumhla wokupapashwa.Ngethuba lexesha lokuqinisekisa, ukuba kukho into entsha kwiteknoloji yemveliso kunye noshintsho olukhulu kwimigangatho yokuvavanya, ishishini liya kuphinda libhengeze.^[2]

Ukulumkela

Hlela Ilizwi

(1) Phambi kokususwa, vuthela uthuli kumphezulu wemoto ngomoya ocinezelweyo kwaye wosule ubumdaka obungaphezulu bucoceke.

(2) Khetha indawo apho injini iqhekeka kwaye icoce indawo engqongileyo.

(3) Ziqhelanise neempawu zesakhiwo semoto kunye neemfuno zobugcisa zolondolozo.

(4) Lungiselela izixhobo (kuquka izixhobo ezikhethekileyo) kunye nezixhobo ezifunekayo ukuze ziqhekeke.
