Sehloohong sena, u tla ithuta ka sensor ea boemo ba XNUMX-wire crankshaft le setšoantšo sa eona sa wiring.

Haeba u kile ua tlameha ho kenya kapa ho leka sensor ea 3-wire crankshaft ka bouena, mohlomong ua tseba hore na e etsoa joang. Ho khetholla lithapo tse 3 ho ke ke ha e-ba bonolo. Ka lehlakoreng le leng, u tlameha ho tseba moo u ka li hokahanyang.

Sensor ea crankshaft ke sesebelisoa sa bohlokoa sa motlakase bakeng sa ho tseba lebelo la enjene le nako ea ho chesa. Sensor ea crankshaft ea terata e 3 e tla le referense ea 5V kapa 12V, lets'oao, le liphini tsa fatše.

"Tlhokomeliso: Ho itšetlehile ka mohlala oa koloi, setšoantšo sa ho hokahanya ha sensor ea crankshaft se ka fapana."

Ithute tsohle ka li-sensor tsa 3-wire crankshaft ho tsoa sengoloa se ka tlase.

U hloka ho tseba ho hong ka sensor ea crankshaft

Mesebetsi ea mantlha ea sensor ea crankshaft ke ho tseba lebelo la enjene le nako ea ho chesa. Sensor ena ke karolo ea bohlokoa ea lienjineri tsa diesel le peterole.

Hlokomela. Ho latela mofuta oa koloi, setšoantšo sa khokahano ea sensor ea crankshaft se ka fapana.

Mohlala, mefuta e meng e tla le sensor ea terata e 2 'me e meng e tla le sensor ea terata e 3. Ho sa tsotellehe boemo leha e le bofe, mochine oa ho sebetsa le morero oa ho hokahanya o ke ke oa fapana haholo.

Keletso e Potlakileng: Sensor ea crankshaft ea 3-wire e ka aroloa e le li-sensor tsa Hall effect. E kenyelletsa makenete, transistor, le thepa ea tšepe e kang germanium.

Setšoantšo sa wiring bakeng sa sensor ea terata e 3 ea crankshaft

Joalo ka ha u bona setšoantšong se kaholimo, sensor ea 3-wire crankshaft e tla ka lithapo tse tharo.

Lithapo tsena tse tharo li hokahane le ECU. Mohala o le mong o tsamaisoa ke ECU. Mohala ona o tsejoa e le terata ea referense ea motlakase ea 5V (kapa 12V).

Mohala oa lets'oao o tloha ho sensor ho ea ho ECU. 'Me qetellong, terata ea fatše e tsoa ho ECU, joalo ka terata ea litšupiso ea 5V.

Reference voltage le signal voltage

Ho utloisisa potoloho ea motlakase hantle, o hloka ho ba le kutloisiso ea litšupiso le li-voltage tsa matšoao.

Matla a referense ke motlakase o tsoang ho ECU ho ea ho sensor. Maemong a mangata, motlakase ona ke 5 V, 'me ka linako tse ling e ka ba 12 V.

Motlakase oa motlakase ke motlakase o fanoang ho ECU ho tloha ho sensor.

Keletso e Potlakileng: Ho hlahloba bukana ea mong'a koloi ea hau ke tsela e molemohali ea ho tseba mofuta oa sensor ea crankshaft. Mohlala, bukana e na le lintlha tse kang mofuta oa sensor le voltage.

Sensor ea terata e 3 e sebetsa joang?

Ha ntho e atamela sensor, matla a makenete a sensor a fetoha, e leng se etsang hore ho be le motlakase. Qetellong, transistor e holisa voltage ena ebe e e romella k'homphieutheng e ka har'a board.

Phapang lipakeng tsa lisensara tsa terata tse 2 le tse 3

Sensor ea terata e 3 e na le likhokahano tse tharo ho ECU. Sensor ea lithapo tse peli e na le likhokahano tse peli feela. E na le lithapo tsa matšoao le tsa fatše, empa ha ho na terata ea litšupiso bakeng sa sensor ea boemo ba XNUMX-wire crankshaft. Mohala oa pontšo o romela motlakase ho ECU, 'me mohala oa fatše o tlatsa potoloho.

Mefuta e meraro ea li-sensor tsa crank

Ho na le mefuta e meraro ea li-sensor tsa crankshaft. Karolong ena, ke tla fana ka tlhaloso e khutšoanyane ea tsona.

inductive

Li-pickups tsa inductive li sebelisa makenete ho nka mats'oao a lerata la enjene. Mefuta ena ea li-sensor e behiloe holim'a cylinder block 'me u tla khona ho beha sensor ea crankshaft haufi le crankshaft kapa flywheel.

Li-sensor tsa mofuta oa inductive ha li hloke referense ea motlakase; ba hlahisa motlakase oa bona. Ka hona, sensor ea terata tse peli ke sensor ea mofuta oa inductive ea crankshaft.

Sensor ea phello ea holo

Li-sensor tsa holo li sebakeng se le seng le li-sensor tsa inductive. Leha ho le joalo, li-sensor tsena li hloka matla a kantle ho sebetsa. Ka hona, li fanoa ka terata ea referense ea voltage. Joalokaha ke boletse, motlakase ona o ka ba 5V kapa 12V. Li-sensor tsena li theha lets'oao la dijithale ho tsoa ho lets'oao la AC le amoheloang.

Keletso e Potlakileng: Li-sensor tsa crankshaft tse nang le terata tse tharo ke tsa mofuta oa Holo.

Li-sensor tsa tlhahiso ea AC

Li-sensor tsa AC li fapane hanyane le tse ling. Sebakeng sa ho romella matšoao a dijithale joalo ka li-sensor tsa Hall, li-sensor tse nang le phallo ea AC li romella lets'oao la motlakase oa AC. Mefuta ena ea li-sensor e sebelisoa hangata lienjineng tsa Vauxhall EVOTEC.

Lipotso tse atisang ho botsoa

Ke lithapo tse kae tse hokahaneng le sensor ea boemo ba crankshaft?

Palo ea lithapo e ka fapana ho latela mofuta oa koloi. Mohlala, mefuta e meng ea likoloi e tla le lisensara tse 2-terata 'me tse ling li tla le li-sensor tsa terata tse 3.

Joalo ka ha u utloisisa, sensor e nang le lithapo tse peli e na le likhoele tse peli, 'me sensor ea terata e meraro e na le likhoele tse tharo.

Hobaneng ha li-sensor tsa 3-wire crankshaft li hloka referense ea motlakase?

Li-sensor tsa crankshaft tse nang le terata tse tharo li hloka voltage ho tsoa mohloling o kantle ho hlahisa motlakase oa lets'oao. Ka hona, li-sensor tsena li tla le li-terminals tse tharo 'me e' ngoe ea tsona e emela voltage ea litšupiso. Li-terminals tse ling tse peli ke tsa likhokahano tsa matšoao le tsa fatše.

Leha ho le joalo, li-sensor tsa 2-wire crankshaft ha li hloke referense ea motlakase. Ba hlahisa motlakase oa bona mme ba o sebelisa ho theha motlakase oa matšoao.

Na motlakase oa referense ke 5V bakeng sa sensor ka 'ngoe ea crankshaft?

Che, motlakase oa litšupiso e ke ke ea e-ba 5V nako le nako. Li-sensor tse ling tsa crankshaft li tla le referense ea 12V. Empa hopola, referense ea 5V ke eona e atileng haholo.

Hobaneng ha referense ea 5V e tloaelehile indastering ea likoloi?

Leha libetri tsa koloi li fana ka lipakeng tsa 12.3V le 12.6V, lisensara li sebelisa 5V feela joalo ka motlakase oa tsona.

Hobaneng ha li-sensor li sa sebelise 12V kaofela?

Hantle, e batla e qhekella. Ka mohlala, ha u qala koloi, alternator ea raha 'me e ntša motlakase o eketsehileng ho tloha ho 12.3 ho ea ho 12.6 volts.

Empa motlakase o tsoang ho jenereithara ha o tsejoe hantle. E ka ntša 12V 'me ka linako tse ling e ka ntša 11.5V. Kahoo ho etsa li-sensor tsa crankshaft tsa 12V ho kotsi. Ho e-na le hoo, bahlahisi ba hlahisa li-sensor tsa 5V le ho tsitsisa motlakase ka motlakase oa motlakase.

A na u ka sheba sensor ea boemo ba crankshaft?

E, u ka e hlahloba. U ka sebelisa multimeter ea digital bakeng sa sena. Sheba khanyetso ea sensor 'me u e bapise le boleng ba ho hanyetsa ka lebitso. Haeba u fumana phapang e kholo lipakeng tsa litekanyetso tsena tse peli, sensor ea crankshaft ha e sebetse hantle.

Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
