Kugogoda mu injini: Zoyambitsa ndi Zotsatira

Aliyense pagalimoto nthawi timamva kugogoda pa ntchito engine. Kodi n'chiyani chinachititsa phokoso izi, ndipo ngati n'zotheka kudziwa makutu zomwe gawo ndi kunja kwa dongosolo?

zimayambitsa Common

Nthawi zambiri, pamene yachibadwa kondomu ndi kuzirala kwa kugogoda mu injini kumachitika chifukwa chakuti mbali zimene zili mwa, ndi chilolezo ukuwonjezeka. Bwinobwino ungabva tenepa amveka bwino pamene kusiyana amakhala pafupi katatu kuposa mtengo mwadzina. Mwamsanga pamene lisaoneke kumawonjezera, mlingo wa avale a injini zigawo ukuwonjezeka ndi kugogoda amakhala mokweza.

Nthawi zina zinthu komwe kugogoda akupezeka injini ndi zabwinobwino ndi kukula kusiyana. Pankhaniyi, izo bwino zimayamba ndi zinthu monga lalikulu injini katundu, misalignment ndi jamming wina wa mbali, kuchepetsa mafuta kukhuthala chifukwa kutenthedwa kapena dilution ndi madzi china (mwachitsanzo, pamene mafuta akulowa mafuta).

Kudziwa kuchimva

Kunena mwakamodzi - kudziwa injini kugogoda khutu zina zovuta ngakhale pang'ono motorman odziwa. Koma malamulo onse alipo.

Ngati pali kugogoda nthawi zonse, muyenera kuyesa galimoto modes osiyana. Monga amadziwika, magawo injini opaleshoni mode ndi liwiro rotational wa crankshaft ndi katundu kumawonjezera monga kutsegula kwa valavu fulumizitsa. Ngati kuchuluka kwa ankasinthana cha phokoso injini ndi nakweza mawu ake, zikuoneka, vuto ayenera anafuna mu za plunger ndipo nthawi lapansi.

Ndi kuwonjezeka katundu kumawonjezera kuthamanga mu zonenepa ndi, safanana, kumawonjezera katundu pa mbali yoyamikira injini - makamaka pisitoni gulu. Choncho, pamaso vuto chimalimba kwambiri monga ukuwonjezeka katundu mu limagwirira tiyipukuse wa kugogoda mu injini.

Tsopano tiyeni tiyese chimatanthauza "kugogoda" item kugogoda kamvekedwe. Ngati injini kusakhala ndi chochita , munamva thud, kenako, ndi changu, kumakhaladi mokweza ndipo nthawi zambiri kuti "kugogoda" ndi crankshaft, amene amavala oyika polumikiza ndodo kapena zimakhudza chachikulu kapena kutsinde magazini. chifukwa mwina mwadzidzidzi m'malo a mafuta kapena mafuta fyuluta.

Thud olimbana "kuzizira" kutanthauza ozizira chiyambi, zingasonyeze avale la mayendedwe a camshaft. Childs, monga kugogoda kumatenga zosaposa angapo masekondi mpaka mafuta afika pa mayendedwe a. Ngati kugogoda ndiye Mwamsanga, ndi camshaft akadali zotheka kuyenda ulendo makilomita 50,000. Kenako kugogoda kukhala lomveka ngakhale pamene kuyambitsa injini ofunda, ndipo inattention kuti galimoto amatsogolera chakuti mafuta ukuwonjezeka, poipa ndi startability wa unit mphamvu, ndipo pali mafunsidwe a coke pa mpando valavu. chifukwa avale camshaft mayendedwe akhale osauka khalidwe mafuta ntchito mayendedwe mafuta otsika kapena kwina, kulowa mafuta kapena madzi zosafunika.

Kuwala zitsulo injini kugogoda zikuchitika ndi kuwonjezeka kasinthasintha zingasonyeze detonation. Kotero ife timachitcha chodabwitsa chimene mafuta watentha maulendo mofulumira kuposa m'mikhalidwe yachibadwa. Pa detonation, yoweyula mantha, zomwe pa gulu la pisitoni pansi ambiri nthawi zimaonekera mwa pisitoni ndi mutu yamphamvu, kuchititsa motero kugogoda chomwecho. Kuwonjezera kugogoda wa kugogoda pa kungasonyeze akuponya mphamvu injini, kugwedeza unit pa ntchito, kutenthedwa ya mutu yamphamvu. Chifukwa detonation ndi ntchito otsika octeni mafuta gawo mapangidwe m'chipinda kuyaka, kulephera kwa vavu EGR. Zotsatira zake zimakhala ndi detonation kuwonongeka kwa pistons ndi pisitoni mphete.
