Ibhonethi, ekwabizwa ngokuba yihood, lelona candelo lomzimba libonakalayo kwaye lelinye lamalungu ahlala ejongwa ngabathengi bemoto. Ezona mfuno ziphambili zokhuselo lwe-injini kukugquma ubushushu, ukugqunywa kwesandi, ubunzima obulula kunye nobungqongqo obuqinileyo.
Isigqubuthelo se-injini ngokuqhelekileyo siqulunqwe ngesakhiwo, sifakwe kwizinto zokugquma ubushushu, kwaye ipleyiti yangaphakathi idlala indima yokomeleza ukuqina. Ijometri yayo ikhethwe ngumenzi, eyona nto iyifom ye-skeleton. Xa ibhonethi ivulwa, ijikeleziswa ngasemva, kodwa nenxalenye encinci yayo ijikelwe phambili.
Isigqubuthelo se-injini esijikiweyo kufuneka sivulwe kwi-engile eqingqwe kwangaphambili kwaye akufanele idibane ne-windshield yangaphambili. Kufuneka kubekho isithuba esincinci esimalunga ne-10 mm. Ukuze kuthintelwe ukuzivula ngenxa yokungcangcazela ngexesha lokuqhuba, isiphelo sangaphambili sesigqubuthelo se-injini kufuneka sixhotyiswe ngesixhobo sokutshixa ikhonkco lokhuseleko. Ukutshintsha kwesixhobo sokutshixa kulungiselelwe phantsi kwedeshibhodi yenqwelo. Xa ucango lwemoto lutshixiwe, isigqubuthelo senjini kufuneka sitshixiwe kwangaxeshanye.
