inzwa ye-crankshaft
I-crankshaft position sensor ingenye yezinzwa ezibaluleke kakhulu ohlelweni lokulawula i-electronic injini. Inikeza isikhathi sokuvutha (i-ignition advance angle) kanye nesignali yokuqinisekisa indawo ye-crankshaft, futhi isetshenziselwa ukubona indawo ephezulu efile yepiston, i-crankshaft rotation angle kanye nesivinini senjini. Isakhiwo esisetshenziswa inzwa yendawo ye-crankshaft siyahlukahluka ngamamodeli ahlukene, futhi singahlukaniswa ngezigaba ezintathu: uhlobo lwe-magnetic pulse, uhlobo lwe-photoelectric kanye nohlobo lweHholo. Ivamise ukufakwa ekugcineni kwe-crankshaft, ngaphambili kwe-camshaft, ku-flywheel noma ku-distributor.
