Gukomeza gutera imbere no kwizigirwa
Moteri ya diesel CAT C7 yarahinduye cane ubuhinga bwo gutwara amakamyo igihe yatangura gukoreshwa mu ntango z’imyaka ya 2000, itanga umuti ukomeye kandi ukora neza ku bikorwa vy’ibikorwa vy’ubuhinga buringaniye-. Nk’abahinga mu gusubira guhingura ibintu twabonye ubwacu ingene iyo moteri yagize ico ikoze ku bikorwa vyacu kandi igashiraho ingingo ngenderwako nshasha mu vyo dukora.
Igishushanyo gishasha
CAT C7 yari yagenewe gushitsa ibisabwa bikomeye cane bijanye n’ugusohora imyuka mibi mu gihe iguma ifise ububasha n’ukwizigirwa Caterpillar yari izwiko. Uburyo bwayo bushasha bwa ACERT (Ikoranabuhanga ryo kugabanya ivyuka biva mu muriro) bwari ubuhinga bwo guhindura urukino-, bwatuma moteri ishobora kwubahiriza amabwirizwa ya EPA ataco ihinduye ku bushobozi.
Kimwe mu bintu bishasha vyakozwe cane ni ubuhinga bwo gukoresha amavuta y’ibitoro bukoreshwa n’amazi (HEUI). Uwo murongo waratuma umuntu ashobora gutera inshinge nyinshi ku rugero rutandukanye, ivyo bikaba vyatuma umuriro ushobora guturika neza kandi bikagabanya n’ibidukikije biva mu mazi. Ubushobozi bwo gutunganya neza-ugutanga amavuta bwari ikintu gikomeye cane mu buhinga bwa moteri.
Igenzura ry'ubuhinga bwa none
ECM (Module de contrôle électronique) yagutse ya C7 yari ikindi kintu kidasanzwe. Iyo ifise ubufatanye bw’ibipimo 120, yarashobora gukora amakuru menshi cane nk’ay’inyenyeri, ivyo bikaba vyatuma umuntu ashobora kugenzura neza neza ubuhinga butandukanye bwo gukoresha moteri. Uwo murongo w’ubuhinga bwa none bwari butagira uko bungana ico gihe kandi bwatumye C7 itandukana n’iziyihiganwa.
Ugukora vyinshi n'ububasha
Ico vy’ukuri catumye CAT C7 itandukanye n’izindi ni uko ishobora gukoreshwa mu buryo bwinshi. Iboneka mu nguvu z’amafarasi kuva kuri 210 gushika kuri 360 hp, n’inguvu z’umuvuduko kuva kuri 520 gushika kuri 925 lb-ft, yoshobora gukoreshwa mu bikorwa vyinshi. Ukwo guhinduranya kwatumye ihitamwo ry’abantu benshi mu nganda zitandukanye, kuva ku gutwara amakamyo y’urugendo rurerure-kugeza ku bikoresho vy’ubwubatsi mbere n’ibinyabiziga vyo kwisamaza.
Ukwizigirwa n'ubuzima buramba
Ku bijanye n’ukwizigirwa, CAT C7 irafise ivyiza vyinshi. Kubera ko izo moteri zifise igitigiri c’ibilometero 450.000 gushika ku 500.000, igice c’izo moteri coshobora gushika ku gice c’imiliyoni y’ibilometero imbere y’uko zisaba guhindurwa cane. Ukwo kubaho kuramba kwatumye iba uburyo bwiza ku barongozi b’amato barondera kwongerera amahera yabo.
Ugukoresha neza amavuta
C7 nayo yarateye intambwe mu bijanye no gukoresha neza amavuta. Ivyo bikoresho vyo mu 2007 vyari bitezwe ko bizotanga iterambere rishika kuri 4% mu bukungu bw’amavuta ku moteri zihuye n’amategeko ya EPA 2004. Ukwo kwongerekana kw’ubushobozi kwari ikintu gihambaye co kugurisha, cane cane uko ibiciro vy’amavuta y’imodoka vyaguma vyiyongera.
Gukomeza gutera imbere
Caterpillar ntiyaruhutse ku vyo yakoze na C7. Iyo moteri yarabonye ugutera imbere gukomeye mu kiringo cose yariko irakorwa. Nk’akarorero, ivyitegererezo vyo mu 2007 vyashizeho uburyo busanzwe bwo gukoresha amavuta y’ibinyabiziga, ivyo bikaba vyatumye amavuta y’ibinyabiziga arushirizaho gutangwa mu buryo bubereye kandi bukora neza.
Ingaruka z'inganda
CAT C7 yarafise uruhara runini mu guhingura isoko ry’ibikamyo vy’ibikorwa vy’ubuhinga buringaniye-. Ugufatanya kwayo, ubushobozi bwayo, n'ukwizigirwa kwayo vyatumye iba ihitamwo ry'abakoresha benshi mu mato. Kuba iyo moteri yaroraniwe kandi vyatumye abayihiganwa bagira ibintu bishasha, ivyo bikaba vyatumye muri rusangi iyo nganda itera imbere.
Naho CAT C7 yari ifise ingorane zimwe zimwe, cane cane ku bijanye n’ibidukikije-bijanye n’ibidukikije mu bigereranyo vya nyuma, ingaruka zayo muri rusangi ku bijanye n’ubuhinga bwo gutwara amakamyo zari nziza ata gukeka. Yarerekanye ko bishoboka gushitsa ingingo ngenderwako zikomeye zijanye n’ibidukikije ata gutakaza ububasha n’ukwizigirwa abatwara amakamyo bishingiyeko.
Moteri ya diesel CAT C7 ihagaze nk’igihe c’ubuhinga bwa Caterpillar mu vy’ubuhinga n’ukwiyemeza gukora ibintu bishasha. Ubuhinga bwayo buteye imbere, ubushobozi bwayo bwo gukoresha ibintu vyinshi be n’ukwizigirwa kwayo vyatumye habaho ivyiza bishasha muri iyo nganda, ivyo bikaba vyatumye iba igice gihambaye cane mu mateka y’ugutwara amakamyo.
