Injini YeToyota 1GR-FE
ISINGENISO SOMKHIQIZO
Injini engu-4.0 litre V6 Toyota 1GR-FE ikhiqizwa emafemini aseJapan nase-USA kusukela ngo-2002 kanti ifakwe kuma-pickup amaningi namaSUV, kodwa yaziwa kakhulu ngeLand Cruiser Prado. Kunezizukulwane ezimbili zale yunithi yamandla: ene-VVT-i kanye nezilawuli zesigaba se-Dual VVT-i.
Ngo-2002, kwatholakala iyunithi entsha engu-4.0 litre kwiLand Cruiser Prado 120 SUV. Ngokuklama, lena injini ye-V6 yakudala yesikhathi sayo ene-engeli ye-camber engu-60°. Isabalalise umjovo kaphethiloli, ibhulokhi ye-aluminium enejakhethi yokupholisa evulekile nemikhono yensimbi ecijile, amakhanda esilinda e-aluminium e-DOHC angenawo ama-hydraulic lifter, i-timing chain drive. Isizukulwane sokuqala sale moto sifakwe ama-VVTi phase shifter kuphela kuma-intake shafts.
Ngo-2009, isizukulwane sesibili salolu phiko saqala ukuvela ku-Land Cruiser Prado 150 SUV, umehluko omkhulu owaba khona abalawuli besigaba se-VVTi kakade kuwo wonke ama-camshaft. Futhi, ukuguqulwa okuningi kwe-motor bekufakwe izinxephezelo ze-hydraulic valve clearance.
Injini ifakwe ku:
● IToyota 4Runner 4 (N210) ngo-2002 - 2009; I-4Runner 5 (N280) kusukela ngo-2009;
●Toyota FJ Cruiser 1 (XJ10) kusukela ngo-2006;

Ukungalungi kwenjini engu-1GR-FE
●Le iyunithi ethembekile engenabo ubuthakathaka ekwakhiweni futhi isizathu esivame kakhulu sokuxhumana nesiteshi sesevisi ukuwohloka kwe-cylinder head gasket ngemva kokushisisa okukhulu kwenjini. Esizukulwaneni sesibili sezinjini, uhlelo lokudla lwahlelwa kabusha futhi le nkinga yashabalala.
●Ngokuvamile, abanikazi babhekana nokuqhekeka kwabalawuli besigaba lapho beqala imoto, kodwa abaningi bashayela kanjena, naphezu kokuthi i-clutch iphukile futhi iyunithi ayizinzile. Izilawuli zesigaba zifakwe amagridi okuhlunga futhi ukuhlanza kwabo kwandisa impilo yesevisi yama-couplings.
●Isizathu esiyinhloko sokusebenza kwenjini entantayo engenzi lutho futhi engazinzile ukungcoliswa komhlangano we-throttle, ama-injection kanye nesihlungi sikaphethiloli ethangini. Futhi esizukulwaneni sesibili, i-valve yesibili yokuphakelwa komoya emuncu iyona enecala.
●Ubuthakathaka buhlanganisa nesistimu yokungenisa umoya ye-crankcase engasebenzi kahle, amakhoyili esikhashana, iphampu, nama-lambda probe azwelayo kwikhwalithi kaphethiloli. Ungakhohlwa ukulungisa ama-valve, izinguqulo eziningi ze-motor azinawo ama-hydraulic lifters.
