Kawuna biyu na Silinda

Mai sana'anta ya mayar da hankali kan abubuwan da ke biyo baya yayin kera sabbin motoci:

• ƙoƙarin ƙara ƙarfi, koma amfani da sigar turbocharged;
• kokarin rage yawan man fetur, ya sabunta tsarin bawul.

An ƙara yawan amfani da mai 6G72 zuwa 800 g/1000 km saboda wasu fasalolin fasaha. Overhaul zai iya bayyana kansa bayan gudu dubu 150-200.

Wasu ƙwararru suna yin bayani dalla-dalla na gyare-gyaren 6G72 ta yuwuwar bambancin ƙarfin injin. Don haka, yana iya samarwa, dangane da sigar: 141-225 hp. Tare da (gyara mai sauƙi tare da bawuloli 12 ko 24); 215-240 l. Tare da (siffa tare da allurar mai kai tsaye); 280-324 l. Tare da (turbocharged version). Ƙimar wutar lantarki kuma sun bambanta: don nau'ikan yanayi na al'ada - 232-304 Nm, don masu turbocharged - 415-427 Nm.

Amma game da amfani da camshafts guda biyu: duk da cewa ƙirar 24-bawul ta bayyana a baya, an yi amfani da tsarin DOHC ne kawai daga farkon 90s na ƙarni na ƙarshe. Tun da farko nau'ikan bawul 24 na injin suna da camshaft ɗaya kawai. Wasu daga cikinsu sun yi amfani da allurar kai tsaye ta GDI, wanda ya ƙara yawan matsi.

Sigar turbocharged na 6G72 sanye take da kwampreso MHI TD04-09B. Ana haɗe masu sanyaya guda biyu tare da shi, tunda ɗayan na'urar ba zai iya samar da ƙarar iska da ake buƙata don silinda shida ba. A cikin sabon sigar injin 6G72, an yi amfani da ingantattun pistons, masu sanyaya mai, nozzles, da na'urori masu auna firikwensin.
