Umcephe wokunyusa Position woluvo: iimpawu, isimiso ukusebenza

Indawo sensor umcephe isikhundla (TPS) iye indawo ebaluleke kakhulu kule nkqubo, nto leyo iliso amafutha idosi ezifunyenweyo. Ngokutsho umqondiso wakhe umlawuli iqala umsebenzi wayo, nto leyo ibandakanya inkcazelo yobume umcephe wokunyusa. Yindlela high isantya utshintsho uphawu kwenziwa elibukhali iimfuno zale enyovwayo licinezelwe, kwaye - into ephambili ukuqinisekisa amafutha idosi efunekayo. Kwimo apho uqale injini esweni caba engile ze aphambuke. Kwaye ukuba evulekile 75 ekhulwini okanye ngaphezulu, lo ngeemoto owenziwe kwindlela ihlanjululwe. A uphawu onika woluvo Indawo umcephe wokunyusa, oluqalayo. Emva kokuba umlawuli iqala ukulawula pxx (Umlawuli we iduma). Ngoko ke umoya kwenziwa kunye injini.

Kufuneka kuqatshelwe ukuba woluvo umcephe esihle elinye igama. Le ndlela yeyona uhlobo ekuthiwa potentiometric equka resistors (rhoqo kunye variable). Ukungawi abangama-8 ohms.

A uphawu olubonisa indawo ivelufa kondliwa nge resistor ukuya esisebenza. Oluphawu elinexabiso kancinci ngaphantsi kwe 0.7 V. Ukuba ombane mkhulu kuno-4 V, ukuba iyunithi yolawulo ugqiba ukuba ivelufa ezivulekileyo ngokupheleleyo. indawo umcephe ngokuqhelekileyo ibekwe umzimba wayo ize idityaniswe esqwini ujikelezo. Axis abe umsantsa olulodwa, nto leyo sakhiwa slot limise. Eneneni, TPS omiswe ngendlela ngezikhonkwane ezimbini.

Akunakwenzeka ukuba akhankanye isivamvo sakufutshane umcephe sikhundla. Injongo yawo ukwenza DC ombane ngokomlinganiselo data kabani engile caba wokuvula, kunye nenkqubo-elekhtrons zokuseza i-injini. Shaft ujikelezo sibhekiswe niye kwicala langasekunene. Le ndlela ke zigxunyekwe umlomo ekhethekileyo (uhlangabezane) kwinkqubo-elekhtrons. Kukho, Kakade ke, ukuba yonke le ufakelo. Kufuneka kuqatshelwe ukuba icebo le mveliso ayikwazi ibe yelinganiselweyo mileage ezindleleni.

Kwaye enye isihloko ukuba ndingathanda ukuyiphatha phezu - i umcephe womenzi woluvo isikhundla Wha. Koomatshini abadala, njengoko waziwa kakuhle, iindlela emiselwe kufuna ingqalelo ekhethekileyo. Yaye ngokufuthi TPS uza azisalungiseki. Ngoko ke, le ndlela yeyona siphene ukuba:

1. Kukho iingxaki kwi lutho.
2. Amvalele phantsi ukudluliselwa - ihambisa injini yemoto.
3. Uphakamisa kuvela rate emisiweyo.
4. Imile isantya "edadayo" phantse kuzo zonke iindlela apho injini uphumeza umsebenzi wayo.

Ukuze kuqinisekiswe ukuba TPS ayisebenzi, kufuneka uwuqwalasele aye kuyenza kakhulu lula. Kufuneka ukuba uvule ucinezelo, ngoko umlinganiselo imveliso ombane phakathi slider kunye "ubunzima". Ukuba ukufunda voltmeter iya kulingana 0.7 V okanye ngaphantsi, yonke into eqhelekileyo.
