Parizvino, injini iyi inongowanikwa muBMW 7 Series, asi ingangove ichakurumidza kuoneka mune dzimwe mhando dzakadai seBMW X5 uye X6. Uyai ivo!
BMW yakawana sei zvakakosha izvi?
BMW ndiyo yaive mhando yekutanga kuunganidza maturbo matatu akatevedzana, uye ikozvino yave zvakare piyona mukubatanidza maturbo mana akatevedzana muinjini yedhiziri.Sezvaunoziva, maturbo anoda exhaust kuyerera kuti ashande - ngatikanganwei nezve kunze kwemutemo uyu, zvinoti Audi electric turbos kana Volvo compressed-air turbos, nekuti handizvo.
Pamarevs akaderera iyi 3.0 litre six-cylinder injini inongomhanya maviri akadzika-pressure turbos panguva imwe chete. Sezvo paine gasi diki diki, zviri nyore kuisa turbos diki kushanda, nokudaro kudzivirira iyo inonzi "turbo-lag". Ehe pakakwirira revs, aya maturbo haakwane…
Ndicho chikonzero nei injini inomhanya ichiwedzera, sezvo kune kuwedzera kwekuyerera uye kumanikidzwa kwemagasi emhepo, magetsi emagetsi emagetsi anopa kurongeka kune throttle system kuti iendese magasi ose emhepo kune 3rd variable geometry turbo. high pressure.
Kubva pa2,500 rpm, iyo 4th hombe turbo inotanga kushanda, iyo inobatsira zvine mutsindo kumhinduro yeinjini iri pakati nepakati nekumhanya.
Saka, chakavanzika chesimba reinjini iyi chiri mune ino turbo uye exhaust gasi kuwiriranisa mutambo. Zvinoshamisa handizvo here?
Kana musoro we "superdiesel" ukasimudza kufarira kwako, tichakwanisa kudzokera kunyaya iyi munguva pfupi. Tisiye maonero ako paFacebook yedu uye tigovane zvedu.
