Injini ye-Nissan KA20DE

Injini kaphethiloli i-KA20DE ene-twin-shaft cylinder head yavela ngo-1991 ithatha indawo ye-2,0-litre Z20 (OHC NA20S yesizukulwane sesibili iNissan Atlas). Iketango lisetshenziselwa ukushayela indlela yalo yokusabalalisa igesi (indlela yesikhathi) (indlela yeketango ebonakala ngokumelana nokugqokwa, ukusebenza buthule, ukumelana nokushintsha kwezinga lokushisa okungazelelwe, futhi ngokungangabazeki ithembeke kakhulu kunamabhande esikhathi senjoloba).

Ukuyishintsha kuyisenzakalo esingavamile, okwenzeka ikakhulukazi ngemva kwekhilomitha elingaphezu kwezinkulungwane ezingu-300 km (ukuhlolwa kokuvimbela kunconywa ngemva kwe-100 km). Ukugqoka okubalulekile kubonakala kanje:

• ukwanda komsindo,
• ukuphuma kwenduku ye-tensioner,
• ukushintsha isikhathi se-valve ngenxa yokugxuma kweketango ngamazinyo angu-1 - 2 (kusethwe ukuhlolwa kwekhompyutha).

Ukushintshwa kweketango kufanele kwenziwe ngokufana ncamashí kwamamaki wesikhathi (ukufakwa okunamamaki okunqamulela kumaketango ahlobene namamaki aku-crankshaft namagiya e-camshaft kungabangela ukwehluleka kwenjini yemoto).

Ukumaka

Incazelo KA20DE imele:

I-KA - Uchungechunge lwenjini (kusukela esigabeni se-in-line 4-cylinder),

20 – Ivolumu (2,0 amalitha),

D - Injini enamakhamera amabili aphezulu (DOCH),

E - Umjovo kaphethiloli we-elekthronikhi.

Uchungechunge lweNissan KA lumelwe amayunithi e-KA20DE, KA24E kanye ne-KA24DE. Ngasohlangothini oluhle, ibonakala ngokulula, ukuthembeka, ukuqina, ohlangothini olubi - ukusetshenziswa kukaphethiloli okuphezulu (ku-KA20DE, amalitha angu-100 - 12 kaphethiloli ashiswa nge-15 km ngemodi yedolobha, 8 - 9 amalitha kumodi yomgwaqo omkhulu. , exutshwe (10/15) - 10,5 l) nobunzima ekulungiseni nasekulungiseni (ikakhulukazi uma kuqhathaniswa neToyota), ehlotshaniswa "nokupakisha" okuminyene kwezingxenye ezingaphansi kwe-hood.

Ukuthembeka okuphezulu nokuqina kwenjini kufakazelwa impilo yesevisi yenjini - kwakungenakwenzeka ukuthola idatha yefekthri, ekusebenzeni, isibonelo, i-Nissan Caravan, yaba ngaphezu kwamakhilomitha ayizinkulungwane ezingu-300 (kuncike ekuhleleni). , esusa cishe i-200 hp emasondweni - ukufakwa kwe-manifold intake, ama-throttle valves, ama-camshaft aneziphethu, i-cylinder head porting, ama-piston abunjiwe angasindi wesilinganiso esiphezulu (~ 11) sokucindezela kanye nezinduku zokuxhuma, ama-injection ... - aphendukayo ibanga elingaphezu kuka-350 XNUMX km).

Isilinganiso senjini ngokusho kwe-drive2.ru singu-4+.

Izimoto ezinenjini ye-KA20DE

Injini evuthayo yangaphakathi ye-KA20DE (ICE) ifakwe kulezi zinhlobo ezilandelayo zakwaNissan (inombolo igxivizwe ohlangothini lwe-exhaust manifold lapho kuhlangana khona injini no-gearbox):

• I-Atlas 10 2000 Super Low GE-SH4F23 (1999 – 2002), TC-SH4F23 (2003 – 2005), H2F23 (1999 – 2003);
• I-Caravan GE-VPE25 (2001 г.), LC-VPE25 (2005 г.);
• I-Datsun GC-PD22 (1999 - 2001);

kanye naku-Isuzu COMO GE-JVPE25-S48D 2001 - 2003, Isuzu ELF ASH2F23, Isuzu Fargo JVPE24.

Zonke izimoto ezisohlwini zibonakala ngokuqukethwe okuphansi kakhulu kwezinto eziyingozi kumagesi aphumayo - injini ifakwe uhlelo lwe-LEV (inkomba ye-E-LEV - ukukhishwa kuhlanzekile ngo-50% kunezindinganiso zika-2000 no-2005). Iyunithi isebenza ngengxube yomoya nophethiloli enesilinganiso esingu-40:1.

Технические характеристики

Imingcele yezobuchwepheshe eyinhloko inikezwe etafuleni:

Umthamo wamafutha agobile ungamalitha angu-4,1. Ukushintshwa kuyanconywa ngemuva kwe-7 - 500 km (ukusetshenziswa cishe ku-15 g nge-000 km). Injini izwela kakhulu ikhwalithi - kufanele ukhethe eyokuqala ochungechungeni "lophethiloli" nge-viscosity ye-500W-1000, 5W-30, 5W-40, 10W-30.

Uma i-KA20DE ihluleka, ungashintshela ku-2.0-litre NP300 nge-114 hp, ekhiqizwa kusukela ngo-2008 kuze kube namuhla.
