Inzwa ye-RPM
Isivinini senjini sinqunywa isilawuli ngokususelwe kusiginali ekhiqizwe inzwa yesivinini se-crankshaft inductive.
Inzwa isebenza nesondo legiya i-ferromagnetic impulse futhi ingafakwa ku-crankshaft in 
i-pulley noma i-flywheel. Ngaphakathi kwenzwa, ikhoyili iboshelwe enkabeni yensimbi ethambile, enye ingxenye yayo exhunywe kuzibuthe unomphela ukuze kwakheke isifunda kazibuthe. Imigqa yamandla yenkundla kazibuthe ingena engxenyeni yegiya yesondo lomfutho, futhi ukugeleza kazibuthe okumboze ukujika ikhoyili kuncike endaweni ehlobene yobuso bokugcina benzwa namazinyo kanye nezikhala phakathi kwamazinyo esondo lomfutho. . Njengoba amazinyo nomphimbo kudlula inzwa, i-flux kazibuthe iyashintsha futhi ibangele i-sinusoidal alternating voltage okukhiphayo ekujikeni ikhoyili. I-voltage amplitude iyanda ngokukhula kwesivinini sokujikeleza. Inzwa ye-inductive ikuvumela ukuthi ulinganise ijubane ukusuka ku-50 rpm.
Ngosizo lwenzwa ye-inductive, kungenzeka futhi ukubona indawo ethile ye-crankshaft. Ukuze uyiphawule, kusetshenziswa indawo yokubhekisela, eyenziwa ngokukhipha amazinyo amabili alandelanayo esondweni lomfutho. Ukwenyuka kwezinotshi phakathi kwamazinyo kuholela eqinisweni lokuthi i-voltage eshintshanayo ene-amplitude enkulu kune-voltage amplitude ebangelwa amazinyo asele kanye nezinotshi eziphakathi kwamazinyo zesondo lomfutho zidaleka ekusongeni kwekhoyili yenzwa.
Uma kunesivinini esisodwa kuphela se-crankshaft kanye nenzwa yokuma kusistimu yokulawula, ukungabikho kwesignali kwenza kube nzima ukubala isikhathi sokubasa noma umthamo kaphethiloli. Kulokhu, awekho amanani okushintsha ahlelwe kusilawuli angasetshenziswa.
Kuzinhlelo eziyinkimbinkimbi ezididiyelwe zokuthungela umjovo, amasignali athathelwa indawo athathwa kuzinzwa ze-camshaft uma ingekho isignali evela kunzwa yesivinini kanye ne-crankshaft position. Ukulawulwa kwenjini kwehlisiwe, kodwa okungenani kungasebenza kulokho okubizwa nge-Safe Mode.
