Injini inogogodza - chii ichocho? Zvikonzero uye mazano ekugadzirisa matambudziko

Panguva yekushanda kwemotokari, vatyairi vanosangana nekukanganisa kwakasiyana-siyana. Kana iwe ukanzwa ruzha rukuru kubva muinjini ine mavibrations akasimba, inogona kunge iri detonation yemusanganiswa wemafuta emhepo. Chikonzero chekusashanda kunofanirwa kutsvakwa nekukasira, sezvo kuramba uchishandiswa kwemotokari kunogona kutungamirira kumigumisiro yakaipisisa nenzira yepistons uye cylinder masvingo akaparadzwa nekuputika, kukuvara kwekubatanidza tsvimbo uye crankshaft. Sei detonation ichiitika, sei kuibvisa uye kuidzivirira mune ramangwana?

Nei injini yekugogodza ichiitika?

Isu takatotsanangura pane yedu portal vodi.su musimboti wekushanda kweinjini yekupisa yemukati. Mafuta, akavhenganiswa muhuwandu hwekupinza nemhepo, anobayiwa kuburikidza nemhuno mumakamuri ekupisa ejini ina-mavhiri. Nekuda kwekufamba kwemapistoni mumasilinda, kudzvinyirirwa kwepamusoro kunogadzirwa, panguva iyo spark kubva pa spark plug inosvika uye musanganiswa wemafuta-mhepo unopisa uye unosundira piston pasi. Ndokunge, kana injini iri kushanda zvakajairika, gasi rekugovera gasi rakanyatso kurongeka, uye kutenderera kwekupisa kwemafuta magungano kunoitika pasina kukanganisa, kudzorwa kupisa kwemafuta kunoitika mairi, iro simba rinoita kuti crank mechanism itenderere.

Nekudaro, mune mamwe mamiriro, ayo atichakurukura pazasi, detonations inoitika nguva isati yakwana. Detonation, mumashoko akapfava, kuputika. Iyo blast wave inorova madziro emasilinda, zvichiita kuti kutenheka kufambiswe kuinjini yese yese. Kazhinji kazhinji, chiitiko ichi chinocherechedzwa kana chisingaiti, kana kana dzvinyiriro pane accelerator ichiwedzera, semugumisiro weiyo throttle valve inozarura yakafara uye kuwedzera kwehuwandu hwemafuta kunopiwa kuburikidza nayo.

Detonation effects:

• kuwedzera kwakanyanya kwekushisa uye kudzvinyirira;
• kudengenyeka kwemhepo kunogadzirwa, iyo inomhanya inosvika mamita 2000 pasekondi;
• kuparadzwa kwezvikamu zvejini.

Ziva kuti nekuda kwekuva munzvimbo shoma, nguva yekuvepo kwekuvhundutsa wave isingasviki churu chesekondi. Asi simba rayo rose rinotorwa nejini, izvo zvinotungamirira kukurumidza kukura kwezviwanikwa zvayo.

Zvinonyanya kukonzera detonation mujini ndezvizvi zvinotevera:

1. Kushandisa mafuta ane yakaderera octane rating - kana maererano nemirayiridzo yaunoda kuzadza AI-98, ramba kuzadza A-92 kana 95, sezvo yakagadzirirwa kuderera kwekudzvinyirira, maererano, ivo vachaputika nguva isati yakwana;
2. Kupisa kwekutanga, kushandura nguva yekudzima - pane kusarura kuti kuputika kwemhepo panguva yekupisa kwekutanga kuchapa simba, izvo kune imwe nzvimbo ndeyechokwadi, asi migumisiro ye "kuvandudzwa kwekushanda kwesimba" yakadaro haisi iyo inofadza zvikuru;
3. Pre-ignition ignition - nekuda kwekuunganidzwa kwe soot uye dhipoziti pamadziro emasilinda, kubviswa kwekupisa neinotonhodza system kunowedzera, macylinders nemapiston anopisa zvekuti gungano remafuta rinobva raputika kana rasangana navo;
4. Kupera kana kupfumisa magungano emafuta - nekuda kwekuderera kana kuwedzera kwehuwandu hwemhepo uye peturu mumagungano emafuta, maitiro ayo anoshanduka, isu takafungawo nyaya iyi kare zvakadzama pa vodi.su;
5. Spark plugs dzakasarudzwa zvisiri izvo kana kupera simba.

Kazhinji kazhinji, vatyairi vemota dzine marefu akareba vanosangana nekugogodza nekugogodza muinjini. Saka, nekuda kwekuiswa pamadziro emasilinda, vhoriyamu yekamuri yekupisa inoshanduka, zvichiteerana, iyo compression reshiyo inowedzera, izvo zvinogadzira mamiriro akanaka ekupisa kusati kwasvika kwemafuta magungano. Somugumisiro we detonations, pasi pepistoni inopisa kunze, iyo inotungamirira kudonho mukudzvinyirira, injini inotanga kushandisa mamwe mafuta uye mafuta. Kumwe oparesheni kunova kusingagoneki.

Nzira dzekubvisa detonation mujini

Kuziva chikonzero chekusashanda, zvichava nyore zvikuru kubvisa. Asi pane zvikonzero zviri kunze kwekutonga kwevaridzi vemotokari. Semuenzaniso, kana motokari yako yakashanda zvakanaka, uye mushure mekuwedzera kwekuwedzera pachiteshi chegesi, kugogodza kwesimbi kweminwe kwakatanga, dambudziko rinofanira kutariswa mumafuta. Kana zvichidiwa, varidzi vezviteshi zvegasi kuburikidza nematare vanogona kumanikidzwa kubhadhara zvizere kukanganisa.

Kana muchina ukashanda kwenguva yakareba pasina mitoro yakakosha, izvi zvinotungamira mukuunganidzwa kwesoti. Kuti udzivise izvi, kanenge kamwe pavhiki iwe unofanirwa kusvina huwandu hwemotokari yako - mhanyisa, kuwedzera mutoro painjini. Mune iyi modhi, mamwe mafuta anopinda mumadziro uye slag yese inocheneswa, nepo utsi hwebhuruu kana kunyange hutema hunobuda mupombi, izvo zvakajairika.

Iva nechokwadi chekutarisa marongero eiyo ignition system, sarudza makenduru akakodzera. Hapana mhosva iwe unofanirwa kuchengetedza pamakenduru. Zadza nemafuta emhando uye mafuta kubva kune vanovimbika vatengesi. Kana nzira idzi dzisina kubatsira, unofanira kuenda kuchiteshi chebasa uye ugoongororwa zvakakwana zvemagetsi emagetsi.
