Ifanelekile kwi-Cummins yoxinzelelo lwe-injini ye-3408589

1.ububele

Kukho iintlobo ezininzi ze-mechanical sensors, ezifana ne-resonant strain gauge pressure sensor, i-semiconductor strain gauge sensor sensor, i-piezoresistive pressure sensor, i-inductive pressure sensor, i-capacitive sensor sensor, i-resonant pressure sensor kunye ne-capacitive acceleration sensor. Kodwa eyona nto isetyenziswa kakhulu yi-piezoresistive pressure sensor, enexabiso eliphantsi kakhulu, ukuchaneka okuphezulu kunye neempawu ezintle zomgca.

2.indima ebalulekileyo

Izinzwa zoxinzelelo azisetyenziswanga kuphela kumlinganiselo wemveliso, kodwa zikwabonwa rhoqo kubomi bethu kule mihla. Uninzi lwezithuthi zethu zinezivamvo zoxinzelelo. Mhlawumbi abaninzi abantu bayazi ukuba kukho iinzwa zoxinzelelo ezimotweni, kodwa eneneni, kukho izibonisi zoxinzelelo kwizithuthuthu eziqhelekileyo.

Amandla esithuthuthu avela ekutsha kweoyile kwicylinder ye-injini yepetroli. Ukutshisa okugcweleyo kuphela kunokunika amandla alungileyo, kwaye ukutsha okulungileyo kufuneka kube neemeko ezintathu: umxube olungileyo, ukunyanzeliswa okupheleleyo kunye nokutshisa okufanelekileyo. Ingaba inkqubo ye-EFI inokulawula ngokuchanekileyo umlinganiselo we-fuel-air ngaphakathi kwinqanaba elifunekayo limisela amandla, uqoqosho kunye ne-emission index ye-injini. Ukulawulwa kwe-air-fuel ratio ye-injini ye-petroli kuqondwa ngokuhlengahlengisa ukunikezelwa kwamafutha okuhambelana nomthamo womoya wokungena, ngoko ukuchaneka komlinganiselo wokuhamba komoya wokungena kuchaphazela ngokuthe ngqo ulawulo oluchanekileyo lomlinganiselo we-air-fuel.

3.isakhiwo sangaphakathi

Iqukethe izinto ze-matrix, i-metal strain wire okanye i-strain foil, i-insulation sheet yokukhusela kunye ne-lead-out wire. Ngokutsho kokusetyenziswa okuhlukeneyo, ixabiso lokumelana ne-resistance gauge ye-resistance gauge inokuqulunqwa ngumyili, kodwa uluhlu lwexabiso lokumelana kufuneka lihlawulwe ingqalelo: ixabiso lokumelana lincinci kakhulu, kwaye umqhubi ofunekayo ngoku ukhulu kakhulu. Kwangaxeshanye, ubushushu begeyiji yoxinzelelo bubangela ubushushu bayo bube phezulu kakhulu. Xa isetyenziswe kwiindawo ezahlukeneyo, ixabiso lokumelana ne-strain gauge litshintsha kakhulu, ukuphuma kwe-zero drift kucacile, kwaye i-zero adjustment circuit inzima kakhulu. Nangona kunjalo, ukuchasana kukhulu kakhulu, i-impedance iphezulu kakhulu, kwaye ukukwazi ukumelana nokuphazamiseka kwe-electromagnetic kwangaphandle akubi. Ngokubanzi, imalunga namashumi eeuro ukuya kumashumi amawaka eeuro.
