Engine mkpakọ

Mkpakọ engine na-enye onye na-abawanye na dị ike si combustion nke mmanụ ụgbọala ngwakọta. The nnọọ echiche na-ewepụtara Latin okwu «compressio» (mkpakọ). Mkpakọ bụ mkpakọ nke gas n'okpuru nduzi nke mpụga agha. Nke a na-eduga ná a Mbelata ya olu. Na elu okpomọkụ ma ọ bụ nrụgide pụrụ ime ihe dị ka mpụga mmetụta. The esịtidem combustion engine (esịtidem combustion engine) dị ka engine mkpakọ emee. Na nke a, mkpakọ nke mmanụ ụgbọala ngwakọta a rụrụ.

Na ọtụtụ aghụghọ nke oge a na ugbo ala ka anọ strok esịtidem combustion engine. Mkpakọ engine ahụrụ isi na combustion ulo na ebe n'etiti ime-ulo mgbidi, mkpakọ mgbanaka na pistin ala. Ọ na-adị mgbe nsogbu esịmde a kacha mgbe pistin nke nta ka ruru larịị nke elu nwụrụ anwụ mgbe, tupu mgbanye nke combustible ngwakọta.

Mkpakọ engine, ewepu na engine derate na ọsọ a na-ewere a ikwu ụfọdụ maka ọnọdụ nke cylinder-pistin esịtidem combustion engine usoro na a ọnụ ọgụgụ nke ndị ọzọ na saịtị. Pistin yiri mgbaaka, valves (oriri na tinyekwa) na isi gasket nke moto unit na a ọnụ ọgụgụ nke n'akụkụ ndị ọzọ na-enye mkpakọ àgwà.

ibu na-ebilite na-ulo nke nwere ike iru iri na ise atmospheres na mmanụ ụgbọala engines. Mkpakọ nke dizel engine a kpụrụ na a mgbali eru iri atọ atmospheres. Na nke a, akụkụ ahụ niile so na-usoro, ga-enwe ike idi ndị dị otú ahụ a na ibu mgbe niile.

Mgbe pistin na-akpali si kere mgbali emee, haruru si penetrating n'ime ọdịiche n'etiti uzo na mgbanaka. Gas n'ihi enwe megide elu nke mgbanaka cylinder.

Ịnọgide ibu na cylinder-pistin usoro, gas nkesa usoro n'ihi na nke mgbe nile na-elu nsogbu imetụta ọnọdụ nke akụkụ. Nke a, n'aka nke ya, agbazee ike na arụmọrụ nke moto. Ọ ga-kwuru na engine mkpakọ (otu) nwere ike ịbụ nnọọ iche. Nke a bụ n'ihi na dị iche iche na ọnọdụ nke n'ihe: okpomọkụ, crankshaft ọsọ, ego nke uzo mmiri ikuku n'ime cylinder.

N'ihi ya, n'ihi na ihe atụ, mmanụ, na-enwe a elu njupụta, viscosity, mkpakọ na-abawanye, dum n'ịkpa na mgbidi nke cylinder, compressing Associated mmiri na gaps. Ngafe mmanụ ụgbọala nke abatakwa cylinder, a washes pụọ mmanụ film, ka mkpakọ na-ebelata.

Na n'ihe nke mkpakọ edoziri na cylinders ọ na-aghọ omume ịchọpụta ihe na-akpata nke ọnụ nke engine ike ma ọ bụ "ihe ọjọọ" na-agba ọsọ ya. Ihe atụ, na ígwè ọrụ na a nso ukwuu karịa otu narị puku iri ise kilomita elu mkpakọ nwere ike mere site guzobere a ịrịba Coke oyi akwa na combustion ulo mgbidi. Nke a, n'aka nke ya, na-ebelata olu nke uji eze. N'ihi nke a, karị, na ụba mkpakọ.

Larịị nke mkpakọ nwere ike tụrụ na ụzọ dị iche iche.

Mgbe oghe trotul rụrụ kacha ekwe omume ikuku eruba n'ime engine. Results nwere ike imetụta leakage nke ikuku cylinders na wear yiri mgbaaka na ọnụnọ nke burnouts, cracks, scratches na mgbidi nke pistin na cylinder, valves na ndị ọzọ na hovering.

Mgbe trotul a na-emechi, ị nwere ike nweta a pụtara ezi egosi nke larịị nke mkpakọ. Na nke a na e nwere obere ego nke oriri ikuku. N'ihi ya, ọ bụ omume na-gbakọọ leakage ịda site deformation mkpara ma ọ bụ valvụ oche-eyi.

Mgbe engine mmalite siri ike, na ọ na-atụ aro maka metering engine bụ oyi. Na nke a mkpakọ dị obere karịa mgbe tụrụ na engine bụ na-ekpo ọkụ. A, n'ihe na-ekpo ọkụ engine ga-rụrụ na a okpomọkụ nke banyere 80-90 degrees. Nke a bụ n'ihi na a ọnụ na viscosity na a ọnụ na gaps n'etiti akpụ akpụ akụkụ.
