Nissan Motors ke mofuta oa sejoale-joale oa enjine o nang le mekhoa e bonolo ea ho reha mabitso bakeng sa enjene ka 'ngoe.

Ana ha se mabitso a enjene e le 'ngoe e khethehileng, empa hape ke mofuta oa mofuta oa eona:

letoto la lihlopha;
molumo;
mokhoa oa ente.
likarolo tse ling tsa enjene.

QG ke lelapa la li-ICE tsa li-cylinder tse 'nè tse entsoeng ke Nissan. Mohala oa sehlahisoa ha o kenyelle feela mefuta ea lienjine tse tloaelehileng tsa DOHC, empa hape le mefuta e fapaneng ea lihlahisoa tse nang le ente e tobileng (DEO Di). Ho boetse ho na le lienjine tse tsamaeang ka khase e metsi QG18DEN. Li-motor tsohle tsa QG li khetholloa ke ho ba teng ha mochine o u lumellang hore u fetole mekhahlelo ea khase, e leng se etsang hore ho khonehe ho nka koloi e le analogue ea VVTi.

Qg18dd e tsejoa e hlahisoa Japane le Mexico. Enjene e lokiselitsoe ho fihlela torque ka RPM e tlase le matla a phahameng a matla. Sena sea hlokahala ho netefatsa hore enjene e arabela pedal. Cast iron e khethoa e le thepa ea ho etsa enjene, hlooho ea silinda e entsoe ka aluminium. Hape, lintlha li na le tšusumetso e kholo litšobotsing tsa ts'ebetso ea enjene:

Ente ea mafura ea MPI;
lithupa tse kopanyang tsa tšepe tse entsoeng;
camshafts e bentšitsoeng;
ho kenngoa ha aluminium ka makhetlo a mangata.

QG18DE e na le theknoloji ea N-VCT e ntlafalitsoeng ke Nissan mme e fane ka Khau ea 2001 ea RJC Technology.

Letoto la enjine ea Nissan QG ke mehlala ea lienjineri tsa peterole tse tukang ka hare tse tsoang ho moetsi oa Nissan Motors. Letoto lena le emeloa ke li-cylinder tse 'nè le li-stroke tse' nè, boholo ba tsona bo ka lekanang le:

Ho ba teng ha tsamaiso ea phetoho ea mohato ho tloaelehile bakeng sa libaka tsa kabo ea khase sebakeng sa shaft ea ho kenya. Lienjineri tse ling tsa mofuta ona li na le sistimi ea ente e tobileng.

Enjene ea 1,8-litre e na le Nissan Variable Cam Timing, e lokiselitsoeng maemo a tloaelehileng a ho khanna teropong. Setšoantšo se arotsoeng se ka bonoa ka tlase. Enjine ea Nissan QG18DD
