Igice cy'ingenzi cy'ibumba ry'imbere ry'imodoka gikoresha ikoranabuhanga ryo gutandukanya imbere, binyuze mu gikoresho gishyushye, no kugenzura valve y'uruhererekane mu kole. Ku mpande zombi z'umuvuduko ufite hejuru nini ihengamye hejuru ihengamye hejuru y'inyubako, ibumba riterwa n'igisenge cy'imbere n'igisenge giteye ni rinini cyane, ibumba rihengamye na plunger bigororotse kuri mm 50 kugeza 60, icyuma gisunika ibumoso gikozwe kuri mm 25 kugeza 35, kinini gihengamye bitewe n'inguni ya dogere 16, kugira ngo habeho inguni irenga dogere 12 hejuru, ugomba gushushanya imiterere y'umurongo w'ubuyobozi, bityo imiterere y'umurongo w'ubuyobozi munini uhengamye hejuru irakozwe. Ingano ntarengwa y'ibumba ni mm 2500 × 1560 × 1790, kandi uburemere ni nka T 30. Reba Ishusho ya 22 ku miterere y'ibumba. Hari imyobo 7 ku ruhande rw'inyuma rw'ibumba ry'imbere, kandi imiterere y'urushinge rw'ibumba rudahinduka ikoreshwa muri ibumba. Imiterere y'ibumba ikoresha ikoranabuhanga rigezweho ryo gutandukanya imbere. Ikoranabuhanga ryitwa "internal partition" rijyanye n'itandukaniro ry'inyuma, ubusanzwe ibicuruzwa rusange bihuye n'imiterere ntarengwa y'ibicuruzwa ku murongo uhoraho w'ifarashi, iyi ni itandukaniro ry'inyuma, ibumba rusange rihuye n'ubu buryo bwo gutandukanya. Ibumba ry'imbere ni uguhisha ipfundo ry'ifarashi ku buso butagaragara bw'ibicuruzwa (ni ukuvuga uruhande rwa B cyangwa uruhande rwa C, ubuso bugaragara ni uruhande rwa A), kandi ipfundo ry'ifarashi ntirishobora kugaragara nyuma yo guteranya ku modoka, kugira ngo ritagira ingaruka ku isura. Kugira ngo uyu murimo ugerweho, imiterere y'ifarashi binyuze mu ikoranabuhanga ryo kugenzura hejuru ihengamye (cyangwa hejuru igororotse) mu mikorere ya gari ya moshi ya kabiri, kugira ngo hamenyekane ko ibice bya pulasitiki bihinduka kandi bigakurwaho, hakoreshejwe iri koranabuhanga rya gari ya moshi ya kabiri rigenzurwa n'uburyo, bwitwa "internal partition technology". Mu gushushanya ibumba ry'imodoka, ikoranabuhanga ryo gutandukanya imbere ryagenewe by'umwihariko ibumba ry'imodoka. Ariko, iri koranabuhanga riragoye kurusha ibumba ry'ifarashi rya hanze mu bugoranye no mu miterere, kandi ingaruka za tekiniki ni nyinshi. Ikiguzi n'igiciro bya ibumba bizaba biri hejuru kuruta irya ibumba ry'ifarashi rya hanze. Ariko, kubera ubwiza bwayo, ikoreshwa cyane mu modoka zo mu rwego rwo hagati n'izo mu rwego rwo hejuru.
Ku bice bya pulasitiki byo mu bwoko bwa auto bumper, muri rusange hariho uburyo bubiri bwo gutandukanya ibintu byo hanze no gutandukanya ibintu byo imbere. Ku gice kinini cyose cy’inyuma ku mpande zombi za bumper, ni ukuvuga ko gutandukanya ibintu byo hanze bishobora gukoreshwa cyangwa gutandukanya ibintu byo imbere bishobora gukoreshwa. Guhitamo ubu buryo bubiri bwo gutandukanya ibintu ahanini biterwa n’ibyo umukiriya wa nyuma akeneye ku modoka ye kuri bumper. Muri rusange, imodoka zo mu Burayi na Amerika zikoresha ikoranabuhanga ryo gutandukanya ibintu byo hanze, mu gihe imodoka zo mu Buyapani zikoresha ikoranabuhanga ryo gutandukanya ibintu byo hanze. Ubwoko bubiri bw’uburyo bwo gutandukanya ibintu bufite ibyiza n’ibibi. Bumper yo hanze igomba gukorana n’umurongo wo gufunga, wongera uburyo bwo gutunganya ibintu, ariko ikiguzi n’uburemere bwa tekiniki bwa bumper yo hanze mu ibumba ni bike ugereranyije n’ubwa bumper yo imbere. Mu ibumba rigabanya ibintu binyuze mu ikoranabuhanga rya kabiri ryo kugenzura inzira ya gari ya moshi, bumper isohoka rimwe gusa, kugira ngo bumper igaragare neza, kandi ikiguzi cyo gutunganya ibice bya pulasitiki n’uburyo bwo kubitunganya kibe kinini. Ariko ikibazo ni uko ikiguzi cya bumper ari kinini, ibisabwa mu ikoranabuhanga rya bumper ni byinshi.
