Sehlopha sa matla 2ZR-FE

The cylinder block e entsoe ka li-alloys tsa aluminium. Li-sleeve li na le lehlakoreng le ka ntle la li-ribbed, tseo li kopantsoeng le thepa ea block bakeng sa khokahanyo e matla le ho ntlafatsa mocheso oa mocheso. Ka lebaka la botenya ba limilimithara tse 7 pakeng tsa li-cylinders, ha ho na phetoho e lebelletsoeng esale pele.

The longitudinal axis ea crankshaft e fokotsoa ke 8 mm mabapi le lilepe tsa lisilindara. Sena se bitsoang desaxage se fokotsa khohlano pakeng tsa piston le liner ha khatello e phahameng e etsoa ka cylinder.

Li-camshaft li behiloe ntlong e arohaneng e behiloeng holim'a hlooho ea block. Li-valve clearance li lokisoa ke li- hydraulic lifters le li-roller tappets/rockers. Koetliso ea nako ke ketane ea mola o le mong (8 mm pitch) e nang le hydraulic tensioner e kentsoeng ka ntle ho sekoahelo.

Nako ea li-valve e fetoloa ke li-actuator tse behiloeng holim'a li-camshaft tsa valve. Li-angles tsa tsona li fapana pakeng tsa 55 ° (inlet) le 40 ° (outlet). Li-valve tsa ho kena li lula li feto-fetoha ka bophahamo ba bophahamo li sebelisa sistimi (Valvematic).
