Cov kws kho mob feem ntau xav txog dab tsi ntawm 70 thiab 100 mmHg los ua li qub . A MAP hauv qhov no qhia tau tias muaj qhov sib npaug txaus hauv koj cov hlab ntsha kom xa ntshav thoob plaws koj lub cev.

Tsuas yog li ntawd, dab tsi yog daim duab qhia chaw sensor nyeem ntawv?

Cov zis hluav taws xob feem ntau nce thaum lub qhov rooj qhib thiab lub tshuab nqus tsev poob. A MAP sensor uas nyeem 1 los yog 2 volts ntawm idle may nyeem 4.5 volts mus rau 5 volts ntawm dav qhib throttle. Cov zis feem ntau hloov pauv txog 0.7 txog 1.0 volts rau txhua 5 ntiv Hg ntawm kev hloov pauv hauv lub tshuab nqus tsev.

Tsis tas li ntawd, PSI yuav tsum nyeem MAP sensor li cas? Ntawm hiav txwv theem, atmospheric siab yog hais txog 14.7 psi (pounds ib square inch). Thaum lub cav tawm, qhov siab tsis txaus sab hauv qhov nqus tau sib npaug ntawm huab cua, yog li MAP yuav qhia txog 14.7 psi. Ntawm lub tshuab nqus tsev zoo, MAP lub ntsuas pa yuav nyeem 0psi ua.

Yog li ntawd, daim ntawv qhia yuav tsum nyob twj ywm li cas?

Li qub idle yuav tsum ua kom ruaj khov nrog tsis pub ntau tshaj 50 RPM kev hloov pauv. Nov yog thawj qhov qhia. Cov MAP kev nyeem ntawv voltage yuav tsum Qhov nruab nrab ntawm 0.9-1.5 volts. Lub tsheb no siab nyob rau lub sijhawm, qhia qhov siab hauv plab thaum noj.

Dab tsi yog qhov kev noj haus manifold siab?

Ib qhov nruab nrab kom tsawg manifold siab nyob ib ncig ntawm -700 mbar (piv txwv li lub tshuab nqus tsev, txheeb ze rau atmospheric siab ). Ib qho kev nyuaj siab me me, ua rau muaj kev cuam tshuam, caij tsheb kauj vab ntawm ib ncig ntawm 21-25 kev nyuaj siab ib pliag. Kev nyuaj siab yog sib npaug hauv qhov dav (ib puag ncig 10 txog 15 mbar).
