Throttle txoj hauj lwm Sensor: yam ntxwv, ua hauj lwm hauv paus ntsiab lus

Txoj hauj lwm sensor throttle txoj hauj lwm (TPS) muaj ib tug heev ib qho tseem ceeb qhov chaw nyob rau hauv lub cev, uas tsom kwm tus tau txais roj koob tshuaj. Raws li nws lub teeb liab xws li pib nws cov hauj lwm, uas muaj xws li lub ntsiab txhais ntawm throttle txoj hauj lwm. By siab npaum li cas cov kev ceev ntawm lub teeb liab hloov yog ua soj ntsuam ntawm lub zog ntawm lub pedal yog pressed, thiab hais tias - lub ntsiab zoo tshaj rau kev txiav txim yuav tsum tau roj koob tshuaj. Nyob rau hauv lub hom nyob rau hauv uas lub cav starting yog saib xyuas nrov plig plawg kaum sab xis ntawm deflection. Thiab yog hais tias nws yog qhib los ntawm 75 feem pua los yog ntau tshaj, lub cev muaj zog yog tshuab txais los ntawm ib tug purge hom. Ib tug teeb liab uas muab ib tug throttle txoj hauj lwm sensor, yog pib. Nws yog tom qab lub maub los pib tswj pxx (regulator ntawm idling). Yog li ntawd huab cua mov yog tau ua thiab cav.

Nws yuav tsum tau muab sau tseg tias throttle txoj hauj lwm sensor muaj lwm lub npe. Qhov no mechanism yog lub thiaj li hu ua potentiometric hom uas muaj xws li resistors (qhov thiab nce mus nce los). Lub kuj ntawm ib tug tag nrho ntawm txog 8 ohms.

Ib tug teeb liab ntawm lub valve txoj hauj lwm yog noj ntawm ib tug resistor mus rau lub maub los. Qhov no teeb liab muaj ib tug nqi uas yog me ntsis tsawg tshaj li 0.7 V. Yog hais tias lub voltage yog ntau tshaj 4 V, lub tswj tsev txiav txim tias tus valve kiag li qhib. Throttle txoj hauj lwm yog feem ntau yog teem nyob rau hauv nws lub cev thiab kev cob cog rua rau txoj kev sib hloov axis. Axis muaj ib tug tshwj xeeb groove, uas yog tsim los ntawm ib tug cruciform qhov. Ua tau, TPS yog tsau by means of ob screws.

Nws yog tsis yooj yim sua tsis hais qhov sib thooj sensor throttle txoj hauj lwm. Nws lub hom phiaj yog los ua kom muaj ib tug DC voltage proportional rau cov ntaub ntawv uas nws qhib kaum sab xis ntawm qhov nrov plig plawg, thiab cov roj txhaj system ntawm lub cav. Cov kev sib hloov ncej yog qhia nyob rau hauv ib tug clockwise kev taw qhia. Qhov no mechanism yog tsau mus rau ib tug tshwj xeeb nozzle (throttling) ntawm cov roj txhaj system. Muaj, ntawm chav kawm, muab txhua yam rau no installation. Nws yuav tsum tau muab sau tseg tias kev pab ntawm cov khoom no tsis tau txwv kev nqi.

Thiab ib lub ntsiab uas kuv xav mus kov li - yog throttle txoj hauj lwm sensor WHA. Nyob rau cov laus cov cav tov, raws li yog zoo paub, tsim mechanisms yuav tsum tau tshwj xeeb mloog. Thiab feem ntau TPS los rau hauv disrepair. Yog li, qhov no mechanism yog cov hais tias:

1. Muaj teeb meem nyob rau kaw.
2. Shuts kis tau tus mob - stalling lub tsheb cav.
3. Jerks tshwm nyob rau ntawm ib tug txheej npaum li cas.
4. Kaw ceev "float" nyob rau hauv yuav luag tag nrho cov hom nyob rau hauv uas lub cav nqa tawm nws cov hauj lwm.

Nyob rau hauv thiaj li yuav xyuas kom meej tias TPS tsis ua hauj lwm, koj yuav tsum mus xyuas nws thiab ua nws yooj yim heev. Koj yuav tsum tig mus rau ntawm tiv cav tseb, ces ntsuas lub voltage ntawm davhlau ya nyob twg slider thiab "hnyav". Yog hais tias lub voltmeter nyeem ntawv yuav ua ncaj rau 0.7 V los yog tsawg dua, txhua yam yog qub.
