Indasitiri yekuvaka ngarava

Mumakore achangopfuura, indasitiri yekuvaka ngarava muChina yakawana budiriro isingaenzaniswi, zvichienderana nehuwandu hwakakodzera hunoratidza kuti muna 2013 kuvaka ngarava muChina kwakapedza matani 4534 ehuremu hwekufa, maodha matsva akasvika matani mamiriyoni 69.84 ehuremu hwekufa. Kubva muna 2010 sekuvaka ngarava pasi rose, China inoramba iri panhamba 1 mumakore mana ari pasi rose.

Indasitiri yekugadzira ngarava ndiyo muenzaniso wedanho rehunyanzvi hwekugadzira munyika. Injini yedhiziri yemugungwa ndiyo midziyo mikuru yekuvaka ngarava, kugadzirwa kwayo kunotungamira indasitiri yezvishandiso zvemuchina kunyanya kugadzirwa kwemidziyo mikuru yemuchina inorema uye hunyanzvi, uye inewo zvinodiwa zvakasimba zvemidziyo yekuyera kuti ienderane nekuyerwa kwezvikamu zvikuru zvemagadzirirwo. Rudzi rwezvikamu zveinjini yedhiziri yemugungwa uye zvikamu zvinoumbwa zvakanyanya nezvikamu zvebhokisi, zvinosanganisira crankcase yepamusoro nepazasi, tsvimbo yekubatanidza, crankshaft, cylinder head, flywheel shell parts nezvimwewo. Zvichienzaniswa nezvimwe zvikamu, ine mabasa ehukuru hwakakura, zvinhu zvakawanda zvekuyera uye kunyatsorongeka kwakanyanya. Saka bhiriji hombe uye gantry hombe chaiyo yekuyera ndiyo mhinduro yakanaka yezvikamu zveinjini yedhiziri yemubhedha uye zvikamu, kunyanya kuyerwa kwemuviri mukuru.

Muviri mukuru sehwaro hweinjini yedhiziri, unotsigira injini yese yedhiziri. Zvikamu zvese uye sisitimu yekubatsira zvakanamirwa zvakananga kana zvisina kunanga pamutumbi, izvo zvinoumba chitarisiko chakaoma uye chiri nyore kuchengetedza. Saka, kuona muviri mukuru ndiko kuyera kwakaomarara kwezvikamu zveinjini yedhiziri.

Nhevedzano yeSPOINT inogona kusangana nezvinodiwa zvekuyerwa kwezvishandiso zvikuru. Tine tekinoroji yepamusoro, maitiro ekugadzira akaomarara ekupa mhinduro dzekuyera dzakarurama uye dzinoshanda dzendege, dziviriro yenyika, kugadzirwa kwemotokari, mold, ngarava, nezvimwewo.
