Enjine ea Nissan VQ25HR
Nissan VQ25HR ke enjene ea 2.5-liter, eo e leng eona e nyane ho fetisisa lelapeng la HR 'me ke yuniti ea 6-cylinder ea sebopeho sa V. E hlahile ka 2006, e fumane crankshaft e entsoeng ka bolotsana le lithupa tse hokelang, mochini oa ho tsamaisa nako, 'me e entsoe ntle le li-compensator tsa haeteroliki.
Ka hona, ho hlokahala ho lokisa li-valve.
Ena ke enjene e ncha e nang le litšobotsi tsa letoto:
- Sistimi ea eVTC ho li-shafts tse peli.
- Lithupa tse hokahaneng tse atolositsoeng le boloko bo bolelele ba cylinder.
- Lipiston tse koahetsoeng ka molybdenum.
- Li-pusher li sebetsoa ho latela theknoloji e khethehileng e se nang hydrogen.

Tshebetso
VQ25HR ke enjene e matla e nang le torque e phahameng ka lebelo le phahameng. Sena se bolela hore motlakase o tlameha ho fetoloa 'me o se ke oa "hulisoa" ka lebelo le tlaase sebakeng sa 2000 rpm, joalokaha bakhanni ba bangata ba etsa joalo. Haeba u lula u sebelisa mochine o tukang ka hare ka lebelo le tlaase, joale ho pheha hoa khoneha, e leng se tla lebisa ho hlaheng ha mehele ea oli ea scraper. Sena se tla bonahala ka tšebeliso e phahameng ea oli, kahoo ho bohlokoa ho laola boemo ba eona ka mor'a lik'hilomithara tse likete tse 100.
Ho ea ka beng ba eona, ketane ea nako ha e lle ka mor'a lik'hilomithara tse likete tse 100 (moetsi o khothalletsa ho e nkela sebaka ka mor'a 200-250 km tse likete.), 'Me litšenyehelo tsa ho e nkela sebaka li tlaase, tseo hape e leng phaello. Sehlopha sa liketane tsa pele le li-tensioners li tla bitsa li-ruble tse likete tse 8-10.
Tšebeliso ea peterole e holimo. Mariha, ka ho khanna ka mabifi, enjene e "ja" lilithara tse 16 tsa mafura, kapa ho feta moo.
Ke habohlokoa ho nahana hore enjene e rata lebelo, 'me e hloka ho se sothe ka matla, kahoo tšebeliso e phahame. Ha u khanna tseleng e kholo, tšebeliso ea peterole ke lilithara tse 10 ka lekholo, e leng sephetho se amohelehang bakeng sa yuniti e matla ea 2.5-litre.
Mathata
Leha taba ea hore enjene ea VQ25HR e ka tšeptjoa ebile e na le lisebelisoa tse phahameng, e fumane mathata a mang:
- Ho chesa haholo. Ho sebetsa ka nako e telele ka lebelo le phahameng haholo ho ka lebisa ho futhumala ho feteletseng. Sena se kanna sa phunya li-cylinder head gaskets. Ka lebaka leo, antifreeze e tla kena likamoreng tse tukang.
- Lebelo la ho sesa le ts'ebetso e sa tsitsang ea enjene e tukang ka hare, e bakoang ke extrusion ea li-gaskets tsa kanale ea oli. Phoso e tsamaisanang e tla hlaha dashboard.
- Keketseho ea tšebeliso ea oli. Lebaka la ho chesa oli ka mor'a lik'hilomithara tse likete tse mashome e tla be e le ho pheha enjene. Ka lebaka leo, mehele ea oli ea scraper ha e sa tla hlola e sebetsa ka katleho ka lebaka la palo e kholo ea carbon deposits.
- Ho ts'oaroa maboteng a silindara. Lienjineng tse sebelisitsoeng, li-scuffs li hlaha maboteng a silinda. Lebaka la ponahalo ea bona ke hore likarolo tsa converter ea catalytic li kena ka likamoreng tse tukang, tse lutlang moo ha li-valve li koetsoe. Ke ka lebaka leo beng ba atisang ho tlosa karolo ea catalyst e haufi le ho tsoa.
Ho akaretsa, VQ25HR ke enjene e tšepahalang le ea boleng bo holimo ea Majapane e se nang liphoso le mefokolo e lebisang mathateng a lefats'e. Ka hona, ka tlhokomelo e nakong le e nepahetseng, enjene e tla "tsamaisa" lik'hilomithara tse likete tse 200 ntle le ho senyeha.

Li-motor tsa konteraka VQ25HR li rekisoa libakeng tse loketseng. Theko ea bona e itšetlehile ka tekanyo ea ho apara, mileage, boemo. Li-unit tse sa sebetseng "bakeng sa likarolo tse setseng" li rekisoa ka li-ruble tse likete tse 20-25, lienjineri tse sebetsang li ka rekoa bakeng sa li-ruble tse likete tse 45-100. Ha e le hantle, litšenyehelo tsa lienjini tse ncha tse lokolotsoeng morao tjena li phahame haholo.
