Kusintha kwanthawi yake kwamafuta ndikofunikira kwambiri pa injini iliyonse yoyaka moto. Injini ya 2TR-FE idapangidwira mafuta opangira 5w30, omwe amayenera kusinthidwa pamakilomita 10 aliwonse. Kwa 2TR-FE, kugwiritsa ntchito mafuta kwa 300 ml pa 1 km kumatengedwa ngati chizolowezi. Pa liwiro lalikulu la injini, mafuta amatha kuwonongeka. The matenthedwe kusiyana mu injini ndi 000 mm.
Ndi ntchito bwino, gwero injini pamaso wotopetsa ndi za 500 - 600 Km, koma ndi kuthamanga 250 Km, m'malo mphete kale chofunika. Ndiko kuti, pofika nthawi yomwe ma cylinders amatopa mpaka kukula koyamba kokonzekera, mphetezo zimasinthidwa kamodzi.
Pa magalimoto ambiri, ndi kuthamanga kwa 120 Km, kutsogolo crankshaft mafuta chisindikizo akuyamba kutayikira. Chida cha injini chimaponyedwa kuchokera ku chitsulo choponyedwa ndipo alibe zokutira faifi tambala, zomwe zimawonjezera gwero ndi ntchito yopanda mavuto ya injini iyi.

Kupanga injini
Ikukonzekera SUVs, ndicho unsembe wa mawilo akuluakulu pa iwo, komanso zipangizo kumawonjezera kulemera kwa galimoto, zimakhala zovuta kuti injini 2TR-FE kukoka misa zonsezi. Ena mwa eni ake amaika ma supercharger (compressors) pamakina, omwe amawonjezera mphamvu ndi torque. Chifukwa choyamba otsika psinjika chiŵerengero, unsembe wa kompresa sikutanthauza kulowerera chipika ndi yamphamvu mutu 2TR-FE.
Pansi pa pistoni ya 2TR-FE silathyathyathya, imakhala ndi ma valve grooves, omwe amachepetsanso chiopsezo cha valve kukumana ndi pisitoni, ngakhale unyolo utasweka, koma ndi ntchito yoyenera, unyolo wa nthawi pa galimoto umatumikira mpaka injini. yasinthidwa.
