Mota epoust yakawanda - kusashanda, zviratidzo, kupera kwakawanda kugadzirisa

Injini yechinhu, iyo ndiyo yakawanda yekubuda, inogona kuita seyakareruka, ine matambudziko akawanda. Ivo zvinoenderana nedhizaini yeyuniti uye akasiyana malfunctions anogona kuitika mumhando dzemotokari dzega. Semuyenzaniso, mune 1.9 TDI injini yeGorofu V, manifold manifold gasket anowanzo kupatsanurwa kubva pamusoro pe cylinder block. Mumagetsi ekare eOpel peturu (2.0 16V), mutswe wakaonekwa pakati pechikamu. Sei iwo manifold ekuneta asingagare zvachose mumotokari dzinopisa mukati?

Sei mapopotera akawanda achikundikana? Zvinhu zvakakosha zvinogona kukuvara

Zvekukosha kukuru kwekuita kweiyo exhaust manifold ndiyo mamiriro ekushanda ehurongwa hwese. Kuita kwayo kunokanganiswa ne:

• tembiricha;
• injini vibration;
• mamiriro emigwagwa;
• kushanda kwemotokari.

Kubata neinjini block kunoita kuti chinhu ichi chidziye kusvika pakupisa kwakanyanya. Exhaust magasi anopfuura nepamhepo inodziya kwazvo (kusvika ku700 degrees Celsius muzvikamu zvepeturu), izvo zvinokanganisa kuwedzera kwezvinhu. Uye zvakare, kudengenyeka kubva muinjini, kusiyanisa kupisa kwekuwedzera kwezvinhu zvakasiyana (aluminium inoita zvakasiyana pane simbi yakakandwa), pesvedzero yekuchinja mamiriro ekunze (chando, madhaka, mvura) uye, pakupedzisira, mashandisirwo emotokari anofanirawo kuwedzerwa. . . Nokudaro, muunganidzi wemotokari anowanzoita malfunctions kubva kumativi ose. Chii chinonyanya kunetsa paari?

Yakatsemuka manifold exhaust - nei izvi zviri kuitika?

Kufurira kukuru pazviri muunganidzi wemotokari kuputika, inosangana nezvinhu zvakasiyana. Simbi yakakandwa, panobva manifold eutsi kazhinji kazhinji inogadzirwa, inodziya zvishoma nezvishoma kupfuura aruminiyamu nesimbi. Naizvozvo, kunyanya kana uchityaira zvakanyanya painjini inotonhora, zvinogona kuitika kuti iyo aluminium block inoita zvakasiyana pane yekukanda simbi yakawanda. Simbi inoburitsa manifold studs inomira zvakanaka kusvika kune tension, izvo zvisiri izvo neakasungwa manifold. Nekuda kweizvozvo, chinhu chinoputsika, sekutonga, pane welding point.

Iyo yakatsemuka manifold epositi chiratidzo chekuputsika uye kukundikana. Kutsiva kana kugadzirisa kunodiwa riini?

Nzira iri nyore yekuziva manifold yakatsemuka ndeye kungotanga injini. Ruzha rwekushanda kwayo rwakasiyana, uye mune dzimwe mota inoshanduka ichichinja zvichienderana nekudzika kana kwepamusoro rpm uye dhigirii reinjini yekudziya-up. Iyo yaimbove yakapfava mashandiro eyuniti uye kunyarara kunofadza mukamba kunoshanduka kuita simbi inoshungurudza ruzha. Nekudaro, hazvizogoneke nguva dzose kuona pakakuvadzwa manifold eutsi. Kazhinji chikonzero chacho microcracks, isingaoneki pasina disassembly uye kuongorora patafura.

Exhaust manifold welding - zvakakosha here?

Kana ukabvunza chero "munhu ane ruzivo" waanosangana naye, anokuudza kuti zvinogona kuitwa. Uye pamusimboti achave akarurama, nekuti muunganidzi anodonha anogona kubikwa. Nekudaro, mhedzisiro yechiito chakadaro haisi nguva dzose (chaizvoizvo kazhinji) yakaipa. Izvi zvinodaro nekuti simbi yakakandwa chinhu chinodiwa zvakanyanya mukugadzirisa. Iyo yakachipa uye yakasimba, asi welding inoda maitiro akakodzera.

Exhaust manifold replacement kana welding?

Munguva iyi, brittleness yezvinhu zve welds inoratidzwa, iyo inogona kuonekwa kana ichitonhora. Kana zvikaitika kuti zvinhu zvose zvakatobikwa zvakanaka, kamwe-kamwe iwe uchanzwa "pop" uye kushanda kwako kwose hakuna maturo. Mukuwedzera, kana welding, muunganidzi anoderedza kuyerera kwayo, izvo zvinokanganisa kushanda kwechikwata. Kugadziriswa kwekamwe chete nenzira iyi kunogamuchirwa, asi zviri nani kutenga chikamu chechipiri muchitoro chendaneti (kunyangwe chakashandiswa), nekuti mutengo ungangove wakafanana.

Zvakadini nekubvisa manifold exhaust?

Kunyangwe iyo manifold yekuburitsa iri fekitori-weld cast iron pombi, ine yakakura kwazvo kukanganisa kuita injini. Hurefu hwemuunganidzi pachahwo hunokanganisa zvakanyanya kuita, sezvinoita chimiro chezviteshi. Uchitarisa pane iyi tsanangudzo, iwe uchaona kuti pane imwe nguva inobatana kuita imwe pombi inopfuura nepakati tambo pasi pejini. Lambda probe inowanzoiswa muexhaust cylinder kuyera exhaust gasi kunaka.

Tuners, zvakare, vanoda kwazvo kushandura iyo yese exhaust system, kutanga neyakawanda, iyo ine simba rakakura pakuwana simba mune akasiyana rpm marenji (kunyanya akakwira). Kubva pane izvi tinogona kugumisa kuti muunganidzi haagoni kuraswa.

Chii chekuita kana paine dambudziko nekuwanda kwekutora? Zviratidzo dzimwe nguva hazvionekwi neziso rakashama, saka zvakakodzera kuonana nenyanzvi. A manifold akakuvadzwa mumotokari haatombokodzeri kugadziriswa, saka zvakanaka kana ukangofunga kutenga chikamu chitsva icho mota isingagoni kuita pasina.
