Injini ya Opel 1,6 SIDI Turbo Ecotec (125 ndi 147 kW)
Galimoto yoyamba kulandira injini yatsopano ya 1,6 SIDI turbocharged mwachindunji inali Opel Cascada yotembenuka. Malinga ndi automaker, injini iyi iyenera kukhala mtsogoleri mkalasi yake pankhani yogwiritsa ntchito, momwe amagwirira ntchito, komanso chikhalidwe.
Injini yoyamba ya mafuta ya Opel yokhala ndi jakisoni wa petulo mwachindunji inali 2,2 kW 114 ECOTEC injini yamphamvu zinayi mu 2003 mu ma Signum ndi Vectra, omwe pambuyo pake adagwiritsidwa ntchito ku Zafira. Mu 2007, Opel GT yotembenuka idalandira woyamba injini ya 2,0-lita turbocharged injini yamphamvu yamphamvu anayi ndi 194 kW. Chaka chotsatira, injini iyi inayamba kuikidwa pa Insignia m'mawonekedwe awiri ndi mphamvu ya 162 kW ndi 184 kW. Astra OPC yatsopano yalandira mtundu wamphamvu kwambiri wokhala ndi mphamvu ya 206 kW. Mayunitsi asonkhana ku Szentgotthard, Hungary.
Injini ya 1,6 SIDI (spark ignition direct injection = spark ignition direct fuel injection) imakhala ndi 1598 cc. Onani ndipo, kuwonjezera pa jekeseni wachindunji, imakhalanso ndi dongosolo loyambira / kuyimitsira. Injiniyi imapezeka pamitundu iwiri yamagetsi 1,6 Eco Turbo yokhala ndi 125 kW yokhala ndi makokedwe apamwamba a 280 Nm ndi 1,6 Performance Turbo yokhala ndi 147 kW komanso makokedwe apamwamba a 300 Nm. Mtundu wotsika wamagetsi umakonzedweratu pankhani yamafuta, imakhala ndi makokedwe othamanga kwambiri komanso imasinthasintha. Mtundu wamphamvu kwambiri udapangidwira oyendetsa magalimoto omwe sachita mantha kuti apindule kwambiri ndi abambo awo.
Pamtima pa injini yatsopano ya SIDI ECOTEC Turbo pali chipika chatsopano chachitsulo chosasunthika chomwe chimatha kupirira kupanikizika kwa silinda wapamwamba kwambiri mpaka 130 bar. Kuti muchepetse kulemera, chipika chachitsulo ichi chimaphatikizidwa ndi crankcase ya aluminium. Chotchinga cha injini chimapangidwa pogwiritsa ntchito ukadaulo wowonda-khoma, womwe umalola kuti ntchito zosiyanasiyana ndi zinthu ziphatikizidwe molunjika pakuponya, zomwe zimachepetsa nthawi yopanga. Lingaliro la zinthu zosinthika limapangitsa kukhala kosavuta kugwiritsa ntchito injini yatsopano mumitundu yosiyanasiyana yamitundu. Ma injini alinso ndi ma bancing shafts, omwe ndi okhawo omwe ali m'kalasi yawo mpaka pano. Miyendo iwiri yolumikizira ili ku khoma lakumbuyo kwa silinda ndipo imayendetsedwa ndi unyolo. Cholinga cha ma shafts ozungulira ndikuchotsa kugwedezeka komwe kumachitika panthawi yogwiritsira ntchito injini yamagetsi anayi. Mitundu ya Eco Turbo ndi Performance Turbo imasiyana ndi ma pistoni omwe amagwiritsidwa ntchito, omwe ndi chipinda choyaka chopangidwa mwapadera pamutu wa pisitoni. Mphete ya pistoni yoyamba ili ndi zokutira za PVD (Physical Vapor Deposition) zomwe zimachepetsa kutayika kwa mikangano.
Kuphatikiza pakusintha kwamapangidwe, makina ojambulira petulo mwachindunji amachepetsanso mafuta (mwachitsanzo, mpweya). Pulagi ndi jakisoni zili pakatikati pa chipinda choyaka moto pamutu wamphamvu kuti zichepetse kukula kwakunja. Izi zimathandizanso kukonza kusakanikirana kapena kuyika kwa chisakanizo. Sitima yamagetsi imayendetsedwa ndi chingwe chosasamala, chosakanikirana ndi maginito, ndipo zida zonyamula ma pulley zimakhala ndi chilolezo chama hydraulic.
Ma injini a 1,6 SIDI amagwiritsa ntchito turbocharger yomangidwa molunjika mu injini yotulutsa utsi. Kapangidwe kameneka kadzitsimikizira kale ndi ma injini ena a Opel ndipo ndiwothandiza potengera zotsalira komanso ndalama zopangira popeza ndizosavuta poyerekeza ndi ma Turin-Scroll turbocharger omwe amagwiritsidwa ntchito mu injini zazikulu. Turbocharger idapangidwira mtundu uliwonse wamagetsi padera. Chifukwa cha kapangidwe kake, injini imapereka makokedwe apamwamba ngakhale pama revs otsika. Kuphatikiza apo, ntchito yachitidwa kupondereza phokoso losafunikira (kulira malikhweru, ma pulsation, phokoso la mpweya woyenda mozungulira masambawo), kuphatikiza kuthokoza kwa otsitsira otsika komanso othamanga kwambiri, opititsa patsogolo kayendedwe ka mpweya komanso mawonekedwe amipata yolowera. Kuthetsa phokoso la injiniyo, chitoliro cha utsi chidasinthidwa, komanso chivundikiro cha valavu pamutu wamphamvu, pomwe zida zapadera ndi zisindikizo zimagwiritsidwa ntchito zosagwirizana ndi kutentha kwakukulu kwa turbocharger yoyandikana nayo.
