Ama-valve agobile nezinye izinkinga ezivamile ngemva kwebhande lesikhathi eliphukile

Ukuziba ibhande lesikhathi kungabiza kakhulu. Amabhande esikhathi awavamisile ukuphuka, kodwa uma ephuka, angonakalisa ama-piston, acekele phansi ama-cylinder heads, futhi alimaze ama-valve enjini. Mhlawumbe uma ucabanga ngenjini yakho, u...

Ukuziba ibhande lesikhathi kungabiza kakhulu. Amabhande esikhathi awavamisile ukuphuka, kodwa uma ephuka, angonakalisa ama-piston, acekele phansi ama-cylinder heads, futhi alimaze ama-valve enjini.

Cishe ucabanga ngamavalvu namapiston uma ucabanga ngenjini yakho, kodwa cabanga kancane ngokuthi yini ewagcina esebenza kahle. Ake sibhekane nakho - ayikho into ebaluleke ngaphezu kwebhande lesikhathi. Ishayela i-camshaft, enikeza isikhathi se-valve, kanye ne-crankshaft, elawula ama-pistons. Ibhande lakho lesikhathi litshela ama-piston ukuthi aphakame futhi awe nini, namavalvu ukuthi avule futhi avale nini.

Ungasho kanjani ukuthi ibhande lakho lesikhathi libi

Amabhande esikhathi awavamisile ukukuxwayisa ngokuthi asezogqashuka - angaklinya noma atshiyoze, noma avele aphuke kungazelelwe. Nokho, kaningi umonakalo uvela ngenxa yokugqokwa kwebhande lesikhathi. Ungenza ukuhlola okubonakalayo ukuze ubone ukuthi akukho yini imifantu, ukucwebezela, amazinyo angekho, noma ukungcoliswa kwamafutha. Noma ungaba umakhenikha akuhlolele ibhande. Abakhiqizi abaningi bezimoto baphinde bancome ukushintshwa kwebhande lesikhathi njengengxenye yokunakekelwa okujwayelekile, kulishintsha njalo ngamamayela angu-60,000. Amanye amabhande mahle amamayela afika ku-100,000, XNUMX. Uma ungabaza, bheka imanuwali yomnikazi noma uxhumane nomthengisi wakho noma umakhenikha.

Izinjini zokuphazamiseka nezingaphazamisi

Izinga lomonakalo odalwe ibhande lesikhathi eliphukile lingancika ohlotsheni lwenjini emotweni yakho. Injini inikeza imvume phakathi kwama-valve nama-piston ngaphandle kokuphazanyiswa, ngakho-ke uma ibhande lesikhathi liphuka, ungagcina usunama-valve agobile futhi kungase kudingeke ukuthi wakhe kabusha amakhanda ama-cylinder, kodwa injini mancane amathuba okuthi ichitheke.

Kodwa-ke, enjini yokuphazamiseka (futhi izimoto ezingaba ngu-70% emgwaqweni namuhla zinalolu hlobo lwenjini), ama-piston nama-valve ahamba ngaphakathi kwe-cylinder, kodwa hhayi ngesikhathi esifanayo. Ama-piston nama-valve "aphethe" isilinda ngezikhathi ezahlukene. Kodwa nansi into - isikhathi phakathi "kokuba" singaba ngaphansi kwesekhondi. Uma isikhathi sivaliwe, kungaba ngaphansi kwesekhondi, akukho okuzovimba amapiston namasilinda ukuthi angashayisani. Lokhu kulahla izinduku zokuxhuma bese ziqala ukubhoboza izimbobo ku-cylinder block. Ngenxa yalokho, injini izomane iqhekeke phakathi, futhi ngeke kwenzeke ukuyilungisa.

Manje uyazi ngemiphumela eyinhlekelele yokunganaki ibhande lesikhathi - ukulimala kwama-valve nama-piston enjini, ama-valve agobile, amakhanda angama-cylinder adinga ukwakhiwa kabusha noma ukushintshwa, futhi mhlawumbe nokubhujiswa okuphelele kwenjini. Uma ungafuni ukuthi lezo zimpawu zedola zihlanganiswe, hlola ibhande lesikhathi njalo futhi ube nomakhenikha esikhundleni salo ngesikhathi.
