Ngithole ukuthi umbuzo we-PSI ongu-5,000 awunayo impendulo eyodwa esebenza kukho konke ukufakwa engikubukezayo. Ngokwami, impendulo eqotho iwukuqoqa idatha yomjikelezo wemisebenzi, ukubala ukonga kwamandla okungokoqobo, nokulinganisa lokho konga ngezindleko ezinkulu zesistimu yokushayela ngokuthuthukiswa kwemoto nengqalasizinda efanele. Ngihlala ngitshela amakhasimende ukuthi ukubala kumele kufake phakathi ukushintshwa kwemoto, ingqalasizinda kagesi, kanye nezindleko zokunciphisa i-harmonic ukuze ngithembeke ngesikhathi sokukhokha. Ngingathanda ukuyeka iphrojekthi engenangqondo ngokwezomnotho kunokufaka imishini ehluleka ukuletha ukonga okulindelwe.

Emisebenzini yokubumba injection ye-shift ezimbili nezintathu esebenza ngaphansi kwengcindezi elinganisiwe, i-VSD iletha imbuyiselo ecacile yezomnotho. Emisebenzini ye-shift eyodwa noma izicelo zomsebenzi oqhubekayo ocindezela kakhulu, ukutshalwa kwezimali kwe-VSD kunzima ukukuthethelela futhi kungase kungalokothi kukhokhe. Indawo ephakathi incike emananini kagesi endawo, ukusebenza kahle kwephampu ekhona, kanye nokubekezelela komqhubi amaphrojekthi amakhulu anembuyiselo yeminyaka eminingi.

Kubathengi abalungele ukuqhuba ukuhlaziywa kokufakwa okuthile, ithimba lethu lobunjiniyela lingabuyekeza idatha yomjikelezo womsebenzi futhi linikeze ukuhlolwa kokufaneleka kwe-VSD. Thumela amalogi okucindezela nokugeleza aqoshiwe ngokusebenzisaikhasi lokuxhumanafuthi sizosebenzisa ukubala ngokuqhathanisa namanani entengo yamanje yezingxenye ze-VSD kanye namanani kagesi ajwayelekile ezimboni. Ukuhlolwa kuvame ukuthatha izinsuku ezimbalwa futhi kunikeza abathengi idatha abayidingayo ukuze benze isinqumo sokutshalwa kwezimali okunolwazi.

Imininingwane yobuchwepheshe kanye nesiqondiso sokukhetha amaphampu nezinhlelo ze-servo okukhulunywa ngazo kulesi sihloko kuyatholakala ku-isikhungo sokulanda. Kubathengi abaqhathanisa i-VSD retrofit nokufakwa kabusha kwesistimu ye-servo hydraulic ephelele, isikhungo sokulanda sihlanganisa nedatha yokuqhathanisa kanye nezifundo zesimo sesicelo.
