The air inlet pressure sensor 274-6720 bakeng sa cat 320D

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.

Setšoantšo sa 1 se bontša kamano pakeng tsa mochine oa khatello ea piezoresistive le k'homphieutha. Setšoantšo sa 2 ke molao-motheo oa ho sebetsa oa piezoresistive intake pressure sensor, le R ho feiga. 1 ke R1, R2, R3 le R4 ka feiga. 2, tse etsang borokho ba Whiston ’me li hokahantsoe le silicon diaphragm. The silicon diaphragm e ka holofala tlas'a ketso ea khatello e feletseng ka har'a mefuta e mengata, e bakang phetoho ea boleng ba khanyetso ea mohanyetsi oa khatello ea R. Ha khatello e phahameng e le teng ka bongata, ho na le ho senyeha ho hoholo ha silicon diaphragm. phetoho e kholo ea bohlokoa ba ho hanyetsa ea mohanyetsi R.. Ke hore, phetoho ea mechine ea silicon diaphragm e fetoloa pontšo ea motlakase, e matlafatsoang ke potoloho e kopanetsoeng le tlhahiso ho ECU.

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 joalo ka sensor ea phallo ea moea, 'me e boetse e angoa ke lintlha tse ngata, kahoo ho na le liphapang tse ngata lipakeng tsa ho lemoha le ho boloka sensor ea moea o kenang, le liphoso tse bakoang ke eona hape. e na le boikgethelo ba yona.
