Gogodza Switch. Nheyo oparesheni uye ongororo

motokari Modern vari vakapakata sensors siyana pahwaro hwokuti kudzorwa chikwata anodzora oparesheni yose chimwe. Rimwe zvinhu izvi munyaya ezvinhu mafuta jekiseni, mumwe detonation Switch, nheyo iyo inobva piezoelectric mugumisiro.

Knock Switch iri motokari injini. Zvinowanisa voltage pulses kubva detonation kuputika injini. Pahwaro uchapupu akawana kubva, kudzorwa chikwata anotonga nerubatsiro huni, nokudaro kuwana kunonyanyisa injini simba uye mafuta rinodyiwa kunyatsoshanda.

The mhando akagogodza sensors

Kune mhando mbiri mudziyo - Broadband uye resonant. Asi zvino resonance akagogodza Switch haina yakanyatsoiswa sezvo pomureza. Unofanirawo kuziva kuti havana kuchinjaniswa, saka akasiyira Somuenzaniso, pane imwe resonant Broadband hakushandi.

musimboti oparesheni

Switch oparesheni anobva piezoelectric mugumisiro. The controller anotumira Switch Mureza kubva DC voltage pamusoro 5V. Iri resistor, iyo kunoderedza voltage kuti 2.5V, uye anodzoka controller AC chiratidzo. neizvi chiratidzo kuchinjirwa rinoitwa nevanhu kuwana bhuku voltage redunhu. Izvi zvinogoneka nokuti controller anogamuchira chiratidzo kubva DC voltage, uye neizvi - AC voltage. Kana kuputika rikaitika injini detonation Switch chiratidzo iri vanowanika AC amplitude uye kakawanda chiri zvakananga novimba detonation simba. Kana panguva dzose mudzimu injini controller anodzoka ane AC chiratidzo voltage 2.5V, kuti controller anosiya injini mashandiro ari mudare nzira. Kana ari zvichiguma mureza ndiwo kutsaudzira iri nzvimbo mutengo, kuti controller anochinja kuti kuvesa nguva, kuti kudzima detonation uye kutapurirana nokushanda injini ari mari uye njodzi nzira.

Vachiongorora akagogodza Switch

Kumba, kugogodza Switch uye huchishanda anogona kuongororwa chete multimeter. Chokutanga, inofanira akochonorwa kubva magetsi connector, uye ipapo sunungura kubva muinjini. Unobva tester kuti vachiongorora sezvinotevera: tsvuku (akanaka) waya zvakabatana imwe kuonana ari connector, uye nhema (kunaka) - kune dzimba. Kuedza kunyatsoshanda zvakakodzera kuti asingaremekedzwi pavanoshandisa neshinda, naro kugogodza Switch vanofanira kubereka pulses anosvika 300 MV voltage, kunonyora ari multimeter. Kana simba RINOFAMBIRA asina kunyoreswa, ipapo Switch kutadza. Kana multimeter voltage anobata pashure nomumwe sitiroko, tarisa Switch connector uye waya. Kakawanda iri mune zvakaipa iriyo hapana kukurukurirana controller uye Switch, saka unofanira kuchenesa vokukurukura. Uyewo tarisa wiring ive remudunhu rakashama. Zvinogoneka kuti waya iri yasvika chete kumwe kana amira.
