Iyo waveform clutter yeokisijeni sensor inokonzerwa necylinder ine isina kunaka kupisa. Ko kusabatidza zvakanaka kweinjini kunokonzera sei kuzara?

Iyo burr uye clutter pane waveform pasi pemamiriro ekusabatidza kwakashata kunokonzerwa nenguva imwe chete yekupisa kana nhevedzano yezviitiko zvekupisa zvisina kukwana kana kusapisa, izvo zvinotungamira kune inoshanda oxidation chikamu chiri kushandiswa mucylinder, uye yakasara yakawandisa okisijeni inoenda iyo pombi yekupedza uye inopfuura kuburikidza neokisijeni sensor. Kana iyo sensor inoona shanduko yeokisijeni kuumbwa mumhepo yekuburitsa, inoburitsa yakaderera kudzvanywa kana burr nekukurumidza, uye nhevedzano yeaya akakwira-frequency burrs anoumba izvo zvinonzi "clutter".

Mhando dzakasiyana dzemoto usina kunaka unoburitsa maburrs.

A) Kupisa kwakashata kunokonzerwa neiyo iginition system (semuenzaniso, akakuvadzwa spark plugs, yakakwira-voltage mitsara, mavhavha evagovera, misoro yekuparadzira, coils yekudzima kana matambudziko ekutanga ekudzima anongokanganisa silinda imwe chete kana peya yemasilinda). Kazhinji iyo ignition oscilloscope inogona kushandiswa kuona matambudziko aya kana kubvisa zvikanganiso izvi);

B) Kupisa kwakashata (zvakasiyana-siyana zvinogoneka zvikonzero) zvakakonzerwa nemusanganiswa wakapfuma unotumirwa kune humburumbira inenge 13: 1 kune yakapihwa mhepo-mafuta reshiyo yemusanganiswa unotyisa;

C) Kupisa kwakashata (zvakasiyana-siyana zvinokonzeresa) kunokonzerwa nekutetepa kwemhepo-mafuta musanganiswa anotumirwa kuhumburumbira ndeye 17: 1 kune yakapihwa njodzi yemhepo-mafuta musanganiswa;

D) Kupisa kwakashata kunokonzerwa ne-cylinder pressure, iyo inokonzerwa nezvinetso zvemagetsi, inoderedza kushandiswa kwemafuta-mhepo musanganiswa usati wapisa uye haigoni kuunza kupisa kwakakwana, iyo inodzivisa kupisa uye inowedzera huwandu hweokisijeni mumhepo inopisa. (zvakadai sekupisa kwevhavha, piston mhete kutsemuka kana kupfeka, kupfeka cam, kunamatira vharafu, nezvimwewo);

E) Silinda imwe kana masilinda akati wandei ane hurema hunokonzerwa nekubuda kwevacuum, iyo inogona kutariswa nekuwedzera propane kune inofungidzirwa vacuum leakage nzvimbo (yekupinda impeller, intake manifold pad, vacuum chubhu, nezvimwewo). Ona kana iyo waveform ye oscilloscope ikava mamwe masaini uye iyo peak inonyangarika nekuda kwekuwedzera kwepropane. Kana musanganiswa uchipinda mucylinder nekuda kwevacuum kuvuza inoenderana necylinder imwe kana akati wandei silinda inodarika 17: 1, kudzima kwakashata kunokonzerwa nekubuda kwevacuum kunoitika.
