Hauv tsab xov xwm no, koj yuav kawm txog XNUMX-xaim crankshaft txoj hauj lwm sensor thiab nws cov kab kos duab.

Yog tias koj twb tau teeb tsa lossis sim 3-xaim crankshaft sensor koj tus kheej, koj yuav paub tias nws ua li cas. Kev txheeb xyuas 3 xov hlau yuav tsis yog ib txoj haujlwm yooj yim. Ntawm qhov tod tes, koj yuav tsum paub qhov twg los txuas lawv.

Lub crankshaft sensor yog ib qho khoom siv hluav taws xob tseem ceeb rau kev txiav txim siab lub cav ceev thiab lub sijhawm sib tsoo. Lub 3-xaim crankshaft sensor los nrog 5V lossis 12V siv, teeb liab, thiab cov pins hauv av, peb tus pins txuas rau lub tsheb ECU.

"Ceeb Toom: Nyob ntawm tus qauv tsheb, daim duab sib txuas ntawm lub crankshaft sensor yuav txawv."

Kawm tag nrho txog 3-xaim crankshaft sensors los ntawm kab lus hauv qab no.

Tej yam koj yuav tsum paub txog lub crankshaft sensor

Lub luag haujlwm tseem ceeb ntawm lub crankshaft sensor yog los txiav txim siab lub cav ceev thiab lub sijhawm ignition. Qhov sensor no yog ib feem tseem ceeb ntawm ob lub cav diesel thiab roj av.

Nco tseg. Nyob ntawm tus qauv tsheb, daim duab sib txuas ntawm lub crankshaft sensor yuav txawv.

Piv txwv li, qee cov qauv tuaj nrog 2-xaim sensor thiab qee qhov tuaj nrog 3-xaim sensor. Txawm li cas los xij, txoj haujlwm ua haujlwm thiab cov txheej txheem kev sib txuas yuav tsis txawv ntau.

Ceev Ntsis: Lub 3-xaim crankshaft sensor tuaj yeem categorized li Hall effect sensors. Nws suav nrog cov hlau nplaum, lub transistor, thiab cov khoom siv hlau xws li germanium.

Cov kab kos duab rau 3-xaim crankshaft sensor

Raws li koj tuaj yeem pom los ntawm daim duab saum toj no, 3-xaim crankshaft sensor los nrog peb cov xov hlau.

Reference kab
teeb liab kab
av

Tag nrho peb cov xov hlau txuas nrog ECU. Ib lub xaim yog siv los ntawm ECU. Cov hlau no hu ua 5V (los yog 12V) voltage siv xaim.

Lub teeb liab xaim mus los ntawm lub sensor mus rau ECU. Thiab thaum kawg, hauv av xaim los ntawm ECU, zoo li 5V siv xaim.

Reference voltage thiab teeb liab voltage

Yuav kom nkag siab txog qhov hluav taws xob hluav taws xob zoo, koj yuav tsum muaj kev nkag siab txog kev siv thiab cov teeb liab voltages.

Kev siv hluav taws xob yog qhov hluav taws xob uas los ntawm ECU mus rau lub sensor. Feem ntau, qhov kev siv hluav taws xob no yog 5 V, thiab qee zaum nws tuaj yeem yog 12 V.

Lub teeb liab voltage yog qhov voltage uas tau muab rau ECU los ntawm lub sensor.

Ceev Ntsis: Kev tshuaj xyuas koj lub tsheb tus tswv phau ntawv yog txoj hauv kev zoo tshaj los txiav txim siab hom crankshaft sensor. Piv txwv li, phau ntawv muaj cov ntsiab lus xws li sensor hom thiab voltage.

Lub 3-xaim sensor ua haujlwm li cas?

Thaum ib yam khoom mus txog lub sensor, qhov sib nqus flux ntawm lub sensor hloov, ua rau muaj qhov voltage. Thaum kawg, tus transistor amplifies qhov voltage thiab xa mus rau lub computer on-board.

Qhov sib txawv ntawm 2-hlau thiab 3-xaim sensors

Lub 3-xaim sensor muaj peb qhov txuas rau ECU. Ib tug ob-xaim sensor tsuas muaj ob txoj kev sib txuas. Nws muaj cov teeb liab thiab hauv av xaim, tab sis tsis muaj cov xaim siv rau XNUMX-xaim crankshaft txoj hauj lwm sensor. Lub teeb liab xaim xaim hluav taws xob xa mus rau ECU, thiab cov xaim hauv av ua tiav lub voj voog.

Peb hom crank sensors

Muaj peb hom crankshaft sensors. Hauv seem no, kuv yuav piav qhia luv luv txog lawv.

inductive

Inductive pickups siv cov hlau nplaum los khaws cov suab nrov ntawm lub cav. Cov hom sensors no tau nruab rau ntawm lub tog raj kheej thaiv thiab koj tuaj yeem tso lub crankshaft sensor nyob ib sab ntawm lub crankshaft lossis flywheel.

Inductive hom sensors tsis xav tau kev siv hluav taws xob; lawv tsim lawv tus kheej voltage. Yog li, ob-xaim sensor yog inductive-hom crankshaft sensor.

Hall effect sensor

Hall sensors nyob rau tib qhov chaw xws li inductive sensors. Txawm li cas los xij, cov sensors xav tau lub zog sab nraud los ua haujlwm. Yog li ntawd, lawv tau muab nrog ib tug voltage siv hlau. Raws li kuv tau hais, qhov kev siv hluav taws xob no tuaj yeem yog 5V lossis 12V. Cov sensors no tsim cov teeb liab digital los ntawm AC teeb liab tau txais.

Ceev Ntsis: Peb-xaim crankshaft sensors yog hom Hall.

AC tso zis sensors

AC tso zis sensors txawv me ntsis ntawm lwm tus. Hloov chaw xa cov cim digital zoo li Hall sensors ua, sensors nrog AC tso zis xa AC voltage teeb liab. Cov hom sensors no feem ntau siv hauv Vauxhall EVOTEC cov cav.

Cov lus nug nquag nug

Muaj pes tsawg cov xov hlau txuas nrog lub crankshaft txoj hauj lwm sensor?

Tus naj npawb ntawm cov xov hlau yuav txawv nyob ntawm tus qauv tsheb. Piv txwv li, qee lub tsheb qauv tuaj nrog 2-xaim sensors thiab qee qhov tuaj nrog 3-xaim sensors.

Raws li koj nkag siab, ob-xaim sensor muaj ob lub xov hlau, thiab peb-xaim sensor muaj peb xaim.

Vim li cas 3-xaim crankshaft sensors xav tau kev siv hluav taws xob?

Peb-xaim crankshaft sensors xav tau qhov hluav taws xob los ntawm ib qho chaw sab nraud los tsim cov teeb liab voltage. Yog li ntawd, cov sensors tuaj nrog peb lub terminals, thiab ib qho ntawm lawv sawv cev rau qhov siv hluav taws xob. Lwm ob lub terminals yog rau cov teeb liab thiab hauv av sib txuas.

Txawm li cas los xij, 2-xaim crankshaft sensors tsis xav tau kev siv hluav taws xob. Lawv tsim lawv tus kheej voltage thiab siv nws los tsim lub teeb liab voltage.

Puas yog qhov siv hluav taws xob 5V rau txhua qhov crankshaft sensor?

Tsis yog, qhov siv hluav taws xob yuav tsis yog 5V txhua zaus. Qee qhov crankshaft sensors tuaj nrog 12V siv, tab sis nco ntsoov, 5V siv yog qhov ntau tshaj.

Vim li cas 5V siv ntau hauv kev lag luam tsheb?

Txawm hais tias lub tsheb roj teeb muab nruab nrab ntawm 12.3V thiab 12.6V, cov sensors tsuas yog siv 5V raws li lawv qhov kev siv hluav taws xob.

Vim li cas cov sensors tsis tuaj yeem siv tag nrho 12V?

Zoo, nws yog qhov nyuaj me ntsis. Piv txwv li, thaum koj pib lub tsheb, lub alternator kicks thiab tso tawm me ntsis ntxiv voltage nyob rau hauv thaj tsam ntawm 12.3 mus rau 12.6 volts.

Tab sis qhov hluav taws xob uas tawm ntawm lub tshuab hluav taws xob yog qhov tsis tuaj yeem xav txog. Nws tuaj yeem tso tawm 12V thiab qee zaum nws tuaj yeem tso tawm 11.5V. Yog li ua 12V crankshaft sensors yog qhov txaus ntshai. Xwb, manufacturers tsim 5V sensors thiab stabilize qhov voltage nrog ib tug voltage regulator.

Koj puas tuaj yeem tshawb xyuas lub crankshaft txoj hauj lwm sensor?

Yog, koj tuaj yeem tshawb xyuas nws. Koj tuaj yeem siv digital multimeter rau qhov no. Xyuas qhov tsis kam ntawm lub sensor thiab muab piv nrog tus nqi nominal resistance. Yog tias koj tau txais qhov sib txawv loj ntawm ob qhov txiaj ntsig no, lub crankshaft sensor tsis ua haujlwm zoo.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
