Iyo N46B18 yaive (itsva): manifold akawanda, alternator uye spark plugs.
Kusiyana neyakajairika N46, yayo 1.8-litre mutsauko yaive: crankshaft yakagamuchira pfupi sitiroko (81 mm); pistons pasi compression reshiyo 10.2; akajairika muunganidzi - pasina DISA. Valvetronic yakabatanidzwa muBosch ME 9.2 system.
Iyo N46B18 magetsi chirimwa, senge yayo 2-litre vhezheni, ine akati wandei emhando dzemhando dzakagadzirwa dzinenge pachigadziko chimwe chete.

Плюсы
- Kudya zvakawanda
- Exhaust camshaft
- Swap Potential
Cons:
- Kuwedzera kushandiswa uye kubuda kwemafuta
- Injini ruzha, vibration
- Matambudziko neValvetronic, pombi yemafuta, CVCG uye vacuum pombi
Chikonzero chikuru chekuonekwa kweanopisa mafuta muN46B18, sezvakaita mujini ye42, kushandiswa kwemafuta ejini yakaderera. Zvakare, dambudziko rinogona kunge riri mukukundikana kwevharuvhu zvisimbiso.
Izvi zvinonyanya kuitika mushure mekumhanya kwe50-100 zviuru zvemakiromita. Oiri isingakurudzirwe nemugadziri inosanganisira mamwe matambudziko. Somuenzaniso, pamwe chete Valvetronic, pombi mafuta, crankcase ventilation valve uye zvichingodaro. Muchiitiko ichi, kuchengetedza pakugadzirisa hazvibatsiri zvachose.
Zvakare, mushure mekumhanya kwe50 zviuru zvemakiromita, iyo cylinder head gasket uye vacuum pombi ingangove yakakumbirwa kutsiva.
Izvo zvinokonzeresa kuzunguzika uye zvisiri zvechisikigo injini ruzha zvinowanzo rara mune yenguva cheni tensioner kana mucheni yakatambanudzwa. Mushure mekumhanya kwe 100-150 zviuru zvemakiromita, matambudziko akadaro haatomboshamisi.
Kuti uderedze mikana yezvinetso neinjini, zvinokurudzirwa kushandura mafuta nenguva, kana kunyange kakawanda, iyo inofanira kuva yepakutanga uye inokurudzirwa nemugadziri. Mukuwedzera, zvakakosha kudururira peturu yakanaka uye kugadzirisa kugadzirisa panguva yakakodzera.
Tuning zvinogona
Zvakare, semamwe madiki ekutamisa 4-cylinder ICEs, iyo N46B18 yakanaka kuchinjika, asi haina kukodzera zvachose kugadzirisa uye nzira chete yakakwana yekuwedzera simba mune iyo ichave chip tuning. Zvingangodaro, zero-resistance sefa ichaiswa mutuning studio, iyo inotungamirwa kuenda kumberi bumper, iyo catalyst ichagurwa uye sisitimu inozovhenekerwa zvachose. Zvese izvi zvichawedzera kusimba uye kuwana +10 hp. Kune chimwe chinhu, iwe unofanirwa kuisa injini pamasilinda matanhatu.
