Iyo muffler yemota inoshanda sei, ndeipi iyo musimboti wekushanda unobva pane

Iyo mota muffler yakagadzirirwa kudzikisa exhaust ruzha mu exhaust system zvinoenderana nemitemo yenyika. Iyi isimbi yesimbi, mukati mayo mapartitions uye makamuri anogadzirwa, achigadzira nzira dzine nzira dzakaoma. Kana magasi ekubuditsa achipfuura nemumudziyo uyu, kutinhira kwemazwi akasiyana-siyana kunotorwa uye kuchinjwa kuva simba rekupisa.

Chinangwa chikuru chemuffler mune exhaust system

Muinjini yekupedza simba, iyo muffler inoiswa mushure meiyo catalytic converter (yemotokari dzepeturu) kana particulate sefa (yeinjini dzedhiziri). Kazhinji, pane maviri:

• Preliminary (silencer-resonator) - yakagadzirirwa kudzvinyirira zvakanyanya ruzha uye kudzikamisa kushanduka mukuyerera kwemagasi emhepo painobuda injini. Inoiswa kutanga, ndicho chikonzero ichiwanzonzi "kumberi". Rimwe remabasa ayo makuru ndiko kugoverwa kwemagasi ekupedza muhurongwa.
• Main Silencer - Yakagadzirirwa yakanyanya kuderedza ruzha.

Mukuita, iyo mota muffler mudziyo inopa shanduko dzinotevera kudzikisa ruzha rwekupedza simba:

• Kushandura chikamu chemuchinjikwa chekuyerera kwemhepo. Inoitwa nekuda kwekuvapo mukugadzirwa kwemakamuri ezvikamu zvakasiyana, izvo zvinokubvumira kuti utore ruzha rwepamusoro-frequency. Nheyo yetekinoroji iri nyore: kutanga, kuyerera kwekufamba kwemagasi emhepo kunopfupika, izvo zvinogadzira kumwe kupikisa kwenzwi, uyezve inowedzera zvakanyanya, semhedzisiro iyo masaisai ezwi anopararira.
• Exhaust redirection. Iyo inoitwa nezvikamu uye kutamiswa kweiyo axis yemachubhu. Nekushandura kubuda kwemhepo pakona ye90 degrees kana kupfuura, ruzha rwepamusoro-ruzha runoderedzwa.
• Shanduko mune gasi oscillations (kupindira kwemafungu enzwi). Izvi zvinowanikwa nekuvapo kweperforations mumapombi iyo inopera inopfuura. Iyi tekinoroji inobvumidza iwe kubvisa ruzha rwemhando dzakasiyana.
• "Autoabsorption" yemafungu eruzha muHelmholtz resonator.
• Kutorwa kwemafungu eruzha. Pamusoro pemakamuri uye maburi, muviri wemuffler une zvinhu zvinotora ruzha kuparadzanisa ruzha.

Mhando dzemufflers uye magadzirirwo awo

Kune marudzi maviri emufflers anoshandiswa mumotokari dzemazuva ano: resonant uye yakatwasuka-kuburikidza. Ose ari maviri anogona kuiswa pamwe chete neresonator (pre-muffler). Mune zvimwe zviitiko, yakatwasuka-kuburikidza nedhizaini inogona kutsiva yekumberi muffler.

Kugadzirwa kwe resonator

Zvimiro, muffler resonator, iyo inonziwo flame arrester, ichubhu ine perforated iri mudzimba yakavharwa, yakakamurwa kuita makamuri akati wandei. Inosanganisira zvinhu zvinotevera:

• cylindrical body;
• thermal insulation layer;
• bofu partition;
• pombi ine perforated;
• throttle.

Resonant silencer mudziyo

Kusiyana neyekutanga, iyo huru resonant silencer yakanyanya kuoma. Iyo ine akati wandei perforated pombi akaiswa mumuviri wakafanana, akapatsanurwa nemapartitions uye ari pamatemo akasiyana:

• perforated front chubhu;
• perforated rear chubhu;
• inlet pipe;
• front baffle;
• chikamu chepakati;
• back baffle;
• exhaust pipe;
• oval body.

Saka, mune resonant silencer, shanduko dzakasiyana-siyana dzemasaisai emhando dzakasiyana-siyana dzinoshandiswa.

Hunhu hwemupfuri wakatwasuka

Chinhu chikuru chakashata cheiyo resonant muffler ndeyekumanikidzwa kwemashure kunokonzerwa nekudzoreredzwa kweiyo exhaust gasi kuyerera (painodhumhana nemabaffles). Panyaya iyi, vatyairi vazhinji vanoita tuning ye exhaust system nekuisa yakananga muffler.

Nemaitiro, iyo yakatwasuka muffler ine zvinotevera zvikamu:

• hermetic kesi;
• kupera uye kupinza pombi;
• hwamanda ine kuputika;
• zvinhu zvinodzivirira ruzha - fiberglass inonyanya kushandiswa inoshingirira kune tembiricha yakakwira uye ine yakanaka-inobata inzwi.

Mukuita, silencer yakatwasuka inoshanda maererano nenheyo inotevera: pombi ine perforated inopfuura nemumakamuri ese. Saka, hapana kudzvinyirirwa kweruzha kuburikidza nekushandura kutungamira uye chikamu chemuchinjiko wekuyerera kwegasi, uye kudzvinyirirwa kweruzha kunowanikwa chete nekuda kwekukanganisa uye kutorwa.

Nekuda kwekuyerera kwemahara kwemagasi ekuburitsa kuburikidza nemberi-kuyerera muffler, inokonzeresa kumashure kudzvinyirira kwakadzika kwazvo. Zvisinei, mukuita, izvi hazvibvumiri kuwedzera kukuru kwesimba (3% - 7%). Kune rumwe rutivi, ruzha rwemotokari runova hunhu hwemotokari yemitambo, sezvo matekinoroji ekudzivirira ruzha aripo anongodzvanya ma frequency akakwira.

Kunyaradza kwemutyairi, vafambi uye vanofamba netsoka zvinoenderana nekushanda kwemuffler. Nokudaro, panguva yekushanda kwenguva refu, kuwedzera kweruzha kunogona kukonzera kukanganisa kwakakomba. Nhasi, kuiswa kwe-direct-flow muffler mukugadzirwa kwemotokari inofamba munzvimbo yeguta imhosva yekutonga inotyisidzira nefaindi uye murairo wekubvisa chigadzirwa. Izvi zvinokonzerwa nekuwanda kwezviyero zveruzha zvakatarwa nezviyero.
