I-bumper inemisebenzi yokuvikelwa kokuphepha, ukuhlobisa imoto kanye nokwenza ngcono izici ze-aerodynamic zemoto. Mayelana nokuphepha, imoto ingadlala indima ye-buffer uma kwenzeka ingozi eshayisana nejubane eliphansi futhi ivikele emzimbeni wangaphambili nangemuva; Kungabavikela abahamba ngezinyawo uma kunezingozi ezinabantu abahamba ngezinyawo. Ngokubona kokubukeka, kuyinto ehlobisayo futhi sekuyingxenye ebalulekile yokuhlobisa ukubukeka kwezimoto; Ngasikhathi sinye, imoto bumper nayo inomphumela othile we-aerodynamic.
Ngasikhathi sinye, ukuze kuncishiswe ukulimala kubagibeli uma kwenzeka ingozi yethonya eliseceleni, umnyango umnyango uvame ukufakwa emotweni ukuze uthuthukise amandla okulwa nokushayisana komnyango. Le ndlela iyasebenza futhi ilula, ngokushintsha okuncane esakhiweni somzimba, futhi isetshenziswe kabanzi. Ngokwango-1993 Shenzhen International Automobile shoobile, iHonda Accord ivule ingxenye yomnyango wokudalula umnyango omkhulu ezilalelini ukukhombisa ukusebenza kwayo okuhle kokuphepha.
Ukufakwa kwe-BUMPER Yomnyango ukubeka imishayo embalwa yensimbi enamandla aphezulu noma ngokuqondile kuphaneli yomnyango womnyango ngamunye, odlala indima ye-bumpers ngaphambili nangasemuva, lapho abagibeli be-iron ", ukuze abagibeli bemoto banendawo yensimbi ephakeme. Vele, ukufaka lolu hlobo lomnyango omkhulu kuzokhulisa izindleko ezithile zabenzi bezimoto, kodwa kubagibeli bezimoto, ukuphepha kanye nomuzwa wokuphepha kuzokwandisa kakhulu.
