Skoda Citigo G-TEC - galimoto yamzinda yokhala ndi fakitale "gasi"

Kuyika kwa makina a LPG kumachepetsa kwambiri mtengo wagalimoto yagalimoto yokhala ndi injini yamafuta. Pali magalimoto opitilira 2,5 miliyoni a LPG m'misewu yaku Poland. Gaz ilinso ndi gulu la othandizira ku Western Europe. M'mayiko ena, magalimoto a LNG opangidwa ndi fakitale ndi otchuka.

Zomera za LPG zimapereka masilinda osakanikirana a propane ndi butane. Chidule cha CNG chikuimira Compressed Natural Gas, kutanthauza kuti, compressed Natural Gas. Mwinamwake, aliyense anali kukhudzana ndi methane - mpweya ndi mafuta kwa mbaula zapakhomo.

Ku Poland, kuchuluka kwa magalimoto omwe adasinthidwa kuti aziyenda pa LNG ndikosavomerezeka. PGNiG ikuyerekeza kuti magalimoto 1700 amayendetsedwa ndi gasi wopanikizidwa. Njira yothetsera vutoli yasankhidwa, makamaka, ndi makampani olankhulana. Chiwerengero cha mabasi a methane chadutsa malire a 200. Ndi makasitomala angati omwe asankha chomera cha CNG? PGNiG imalankhula za magalimoto 700.

N'chifukwa chiyani LNG inalephera ngati mita ya kiyubiki ya mafutawa imawononga PLN 3,3-3,8, ndipo mutagula kompresa yoyenera, mukhoza kudzaza galimoto ndi gasi kuchokera panyumba, zomwe zimachepetsa mtengo wa 1 m3 wa methane ku PLN 2,5? Masilinda a CNG ayenera kupirira nthawi 10 kukakamiza kwa masilinda a LPG. Zofunikira za mapangidwe zimawonetsedwa mu kulemera kwawo kwakukulu komanso mtengo wogula kwambiri.

Mwachidule, tingaganize kuti kukhazikitsa HBO akhoza recoup mtunda wa makilomita 20-30 zikwi. Wogwiritsa ntchito galimoto yamagetsi asanayambe kupeza ndalama zenizeni, ayenera kugonjetsa 40-50 zikwi. km.

Magalimoto a gasi ndi okonda zachilengedwe. Kuyaka kwa CNG kumatulutsa tinthu tating'onoting'ono ta zinthu ndi sulfure. Kutulutsa kwa nitrogen oxides kumachepetsedwa ndi 50-80%. Gawo lamphamvu la methane lili ndi mankhwala ochepera a carbon kuposa mafuta ena, omwe amachepetsa mpweya wa carbon monoxide (mpaka 80%) ndi carbon dioxide (pafupifupi 20%). Dongosolo lodzaza thanki la Hermetic limachotsa kutulutsa kwa nthunzi mumlengalenga panthawi yamafuta.

Skoda ndi imodzi mwazinthu zomwe zimapereka magalimoto okhala ndi fakitale ya CNG. Chodetsa nkhawa cha Czech chimapatsa makasitomala Citigo G-TEC, Octavia G-TEC ndi Octavia Combi G-TEC. Kuwonetsedwa kwamitundu yonse kunachitika ku Netherlands. Tidaganiza zofufuza ngati Citigo G-TEC ndiyopanda ndalama monga momwe wopanga amalonjeza. Skoda akuti imadya 4,4 m3 (2,9 kg) ya LNG pa 100 kilomita. Izi zikutanthauza kuti mudzalipira PLN 100 paulendo wa 10 km.

Citigo G-TEC ili ndi matanki atatu amafuta - awiri a CNG ndi amodzi amafuta. Matanki amafuta amanyamula malita 35 ndi 37 a LNG, omwe ndi ofanana ndi ma kilogalamu 11 a methane. Malo a silinda ang'onoang'ono adamasulidwa pochepetsa tanki yamafuta mpaka malita 10. Malo pambuyo pa niche ya gudumu yopuma adatengedwa ndi botolo la gasi la 37-lita. Pali zida zokonzera pansi pa thunthu, ndipo chipinda chonyamula katundu chawonjezeka kuchokera pa 251 mpaka 213 malita.

Kusintha sikuthera pamenepo. Injini ya 1.0 MPI yakhala ikusintha zambiri kuti ipititse patsogolo kuyaka kwa kusakaniza kwa mpweya wa gasi ndikutsimikizira kuti injiniyo ikhale yabwino ngakhale pamtunda wautali. Chinasintha n’chiyani? Chiŵerengero cha kuponderezana chinakwezedwa kuchokera ku 10,5: 1 mpaka 11,5: 1, ma valve, maupangiri awo ndi mipando adalimbikitsidwa, ma spark plugs adakulungidwa m'mutu. Maonekedwe a makamera a camshaft ndi mapangidwe a chothandizira asinthidwanso - pamene methane ikuwotchedwa, mankhwala ochepa a poizoni amapangidwa, zomwe zinapangitsa kuti kuchepetsa kuchuluka kwa zitsulo zamtengo wapatali muzitsulo zowonongeka.

Kompyuta yoyang'anira injini yakonzedwanso. Anapezanso ma aligorivimu kuti adziwe kuchuluka kwa ma calorific a gasi ndikusintha kuchuluka kwa LNG yomwe imadyetsedwa. Ngati kutentha kozizira kupitirira -10 ° C, injini ya Skoda Citigo G-TEC idzayendera gasi. Kukatentha kwambiri, kumatenthedwa ndi petulo, zomwe nthawi zambiri sizitenga mphindi ziwiri.

Vavu yodzaza methane imabisika pansi pa hatch tank ya gasi. Inagwiritsanso ntchito muyezo wamafuta, kuonjezera sikelo ya CNG, ndikufupikitsa sikelo ya mafuta. Malo a dzanja amasonyeza njira ya zakudya. Nthawi yosinthira kuchokera ku gasi kupita ku petulo imasankhidwa ndi zamagetsi. Dalaivala sangathe kusokoneza ndondomekoyi.

Kuyendetsa Skoda Citigo G-TEC sikusiyana kwambiri ndi kuyendetsa Citigo pogwiritsa ntchito mafuta wamba. Ndi kung'ung'udza kwa ma silinda atatu, galimotoyo imanyamuka ndikuthamanga bwino mpaka 70 km / h. Pambuyo pake, pali kuchepa pang'ono kwa torque (90 m'malo mwa 95 Nm) ndi kuwonjezeka kwa kulemera kwazitsulo (956 m'malo mwa 857 kg). Kuthamanga kuchokera ku 0 mpaka 100 km/h kumatenga masekondi 16,3. Zambiri, komabe, sizikutanthauza kuti Citigo G-TEC idzagwira ntchito mumzindawu. Liwiro pazipita kufika 164 Km / h, kotero pokonzekera ulendo, simuyenera kuwoloka motorways ndi Expressways panjira. Ndi zofunikanso chifukwa kuwoloka panjira ya njira imodzi kungakhale kovuta. Mphamvu yochepera ya injiniyo idzakakamiza kuti ipangitse kutsika pafupipafupi ndikutsika kuchokera pa giya lachisanu mpaka lachitatu.

Akatswiri, pofuna kuwonetsetsa kuyendetsa bwino komanso kuchepetsa mphamvu ya aerodynamic drag, adachepetsa chilolezo cha Citigo G-TEC ndi 15 mm. Kusinthidwa pang'ono kuipa njira damping tokhala, koma yaing'ono Skoda amapereka chitonthozo chovomerezeka galimoto.

Wopangayo akuti pophatikizana, Citigo G-TEC iyenera kugwiritsa ntchito 2,9 kg ya methane pa 100 km ya njanji. Galimotoyo inawotcha 150 kg / 3,1 Km pa mtunda wa makilomita 100. Ku Netherlands, kilogalamu ya methane imawononga ma euro 1,095. Izi zikutanthauza kuti ma kilomita 100 a injini yamafuta ya Citigo amawononga ndalama zofananira ndi PLN 14.

Ofesi yoimira ku Poland ku Skoda sikufuna kubweretsa Citigo mu mtundu wa G-TEC kumsika wanyumba. Ma network ochepa a 30-point of CNG filling station amapangitsa kuti zikhale zovuta kugwiritsa ntchito magalimoto oyendetsedwa ndi methane. Poyerekeza, tikuwonjezera kuti ku Netherlands yaying'ono kwambiri, LNG ingagulidwe pamasiteshoni a 1300. Mitengo idzakhalanso chinthu chomwe chimalepheretsa chidwi cha chitsanzocho. Ku Germany, Skoda Citigo Active yotsika mtengo kwambiri imawononga 9690 12 mayuro. Mtundu wa Active G-TEC umawononga 640 1300 mayuro. Skoda idapereka Citigo G-TEC kwa makasitomala chaka chatha. Mpikisano mu kagawo kakang'ono kameneka ndi kofunikira. Amene ali ndi chidwi akhoza kusankha Fiat Panda CNG, Lancia Ypsilon TwinAir EoChic, Seat Mii Ecofuel ndi Volkswagen up! EcoFuel.

Zinthu zandale, makamaka VAT, kuchotsera, zolipiritsa ndi zowonjezera, zimakhudza kwambiri phindu logwiritsa ntchito magalimoto okhala ndi mphamvu zina. Kutulutsa 79 g CO2/km

ndi gulu lamphamvu A+ amalola wogula wa Citigo G-TEC kuti agwiritse ntchito phindu lililonse.
