Injini iri kushanda ichaonekwa sechinhu chinokonzeresa kusvetuka-svetuka, panguva ino bracket yeinjini inokosha zvikuru. Kushandisa rutsigiro rweinjini hakungogadzirisi nzvimbo yeinjini chete, asiwo kunoita kuti injini isasvetuka-svetuka, kuitira kuti injini ichengetedze kuchengetedzeka kwayo, kuitira kuti muridzi agone kuzorora achityaira. Muchidimbu, rutsigiro rweinjini rwakakamurwa kuita mhando mbiri. Rimwe irutsigiro rwetorque, rimwe iguruu retsoka yeinjini. Guruu retsoka yeinjini rinonyanya kushandiswa kugadzirisa kudonha kweshock. Guruu retorque rudzi rwechisungo cheinjini, chinowanzo batanidzwa neinjini iri paaxle yepamberi yemuviri wemotokari. Musiyano neguruu retsoka yeinjini yakajairika ndewekuti guruu retsoka iguruu rakaiswa zvakananga pasi peinjini, uye rutsigiro rwetorque rwakafanana nechitarisiko chetsvimbo yesimbi yakaiswa padivi peinjini. Pachavawo neguruu retorque pabracket retorque, iro rinoshanda sechinobvisa kusvetuka-svetuka. Guruu reinjini rakagadzirirwa kubata injini panzvimbo, saka kana chimwe chinhu chikafamba zvisina kunaka nayo, haizobati zvakachengeteka. Zvadaro, kana injini ichishanda, pachava nedambudziko rekumhanya-mhanya, uye kana injini ichimhanya zvakanyanya, tisingatauri kuti, kwete chete neruzha rusina kujairika rwekuti "boom", mazwi akakomba achaita kuti injini irove.
