Likarolo tsa koloi bakeng sa Dongfeng Cummins intake pressure sensor 4921322

Manifold Absolute Absolute Pressure Sensor (MAP).

E hokela manifold a kenang ka pompo ea vacuum, 'me ka lebelo le fapaneng la lebelo la enjine, e utloa phetoho ea vacuum ka har'a manifold, ebe e e fetola lets'oao la motlakase ho tloha phetohong ea khanyetso ea kahare ea sensor hore ECU e lokisoe. boholo ba ente ea mafura le nako ea ho tima.

Ka mochine oa EFI, mochine oa khatello ea ho kenngoa o sebelisoa ho lemoha molumo oa moea o kenang, o bitsoang D-type injection system (mofuta oa lebelo la sekhahla). Sensor ea khatello ea moea e kenang e lemoha molumo oa moea o kenang ka tsela e sa tobang ho fapana le ka kotloloho e le sensor ea phallo ea moea. Ka nako e ts'oanang, e boetse e angoa ke lintlha tse ngata, kahoo ho na le liphapang tse ngata pakeng tsa ho lemoha le ho hlokomeloa ha sensor ea moea e kenang, 'me liphoso tse bakoang ke eona le tsona li na le tse khethehileng.

Sensor ea khatello ea ho kenya e lemoha khatello e feletseng ea manifold a ho noa ka morao ho throttle. E lemoha phetoho ea khatello e felletseng ka har'a manifold ho latela lebelo la enjene le mojaro, ebe e e fetolela ho motlakase oa lets'oao ebe o e romela ho unit control unit (ECU). ECU e laola boholo ba ente ea mafura ho latela matla a lets'oao.

molao-motheo oa ts'ebetso

Ho na le mefuta e mengata ea li-sensor tsa khatello ea maikutlo, joalo ka varistor le capacitor. Ka lebaka la melemo ea nako ea karabelo e potlakileng, ho nepahala ho phahameng ho lemoha, boholo bo fokolang le ho kenngoa habonolo, varistor e sebelisoa haholo tsamaisong ea ente ea mofuta oa D.

sebopeho sa ka hare

Mochine oa khatello o sebelisa mochine oa khatello bakeng sa tekanyo ea khatello, 'me mochine oa khatello o kopanya borokho ba Wheatstone holim'a silicon diaphragm e ka senyehang ke khatello. Chip ea khatello ke motheo oa sensor ea khatello, 'me baetsi bohle ba ka sehloohong ba li-sensor tsa khatello ba na le li-chips tsa bona tsa khatello, tse ling tsa tsona li hlahisoa ka ho toba ke baetsi ba li-sensor, tse ling tsa tsona ke li-chips tse khethehileng (ASC) tse hlahisoang ke ho tsoa. , 'me e' ngoe ke ho reka ka ho toba li-chips tsa morero o akaretsang ho baetsi ba litsebi ba li-chip. Ka kakaretso, li-chips tse hlahisoang ka kotloloho ke baetsi ba sensor kapa li-chips tsa ASC tse ikhethileng li sebelisoa lihlahisoa tsa bona feela. Li-chips tsena li kopantsoe haholo, 'me chip ea khatello, potoloho ea amplifier, chip ea ts'ebetso ea matšoao, potoloho ea ts'ireletso ea EMC le ROM bakeng sa ho lekanya sekhahla sa tlhahiso ea sensor kaofela li kopantsoe ho chip e le' ngoe. Sensor kaofela ke chip, 'me chip e hokahane le PIN ea sehokelo ka li-lead.
