Ụgbọala anọ na-strok engine

Esịnede anọ engine cylinders, nke na-ndokwasa na crankcase na n'elu mechiri emechi isi. Carter ala tree ekekọtara. Na cylinder isi valves na-setịpụrụ - uzo mmiri ma tinyekwa, na nozulu maka ọgwụ nke manu (dizel) engines ma ọ bụ icheku ọkụ mgbanye (petrol). Inside na pistin Nkea, jikọọ site pistin pin na elu isi nke ejikọta mkpara. The ala isi nke ejikọta mkpanaka kpuchie cervix crankshaft isi magazin nke na-n'ịnyịnya na biarin. The pistin na cylinder na-anọkwasị site pụrụ iche yiri mgbaaka. Ná ngwụsị nke na-crankshaft bụ ofu flywheel.

A na-akpọ elu nwụrụ anwụ mgbe ọnọdụ ji nke pistin na njedebe nke ya elu ọrịa strok, na ala nwụrụ anwụ ebe a na-akpọ ọnọdụ nwere na njedebe nke bụ ala njem.

Akọ na-akpọ ije nke pistin si onye nwụrụ anwụ center ọzọ. Ndahie kpụrụ ya mgbe ọ na-ahụrụ na TDC, na combustion ulo bụ a oke. engine Ndahie ma ọ bụ ndị Ndahie olu - bụ ego tọhapụrụ site pistin mgbe akpụ akpụ site na ndị nwụrụ anwụ na-ekwu. Olu nke cylinder - a ngụkọta uru nke combustion ulo na-arụ ọrụ.

Mkpakọ ruru bụ akụkụ dị mkpa, nke a na-kọwaa dị ka ndị ruru nke zuru cylinder olu na mkpokọta olu nke combustion ụlọ. Modern otu-cylinder engine nwere a mkpakọ ruru nke banyere 10. The otu-cylinder anọ strok engine nwere elu mkpakọ ruru, ihe na-erughị 20.

Anọ strok engine ná mmalite nke oriri ọrịa strok mgbe oriri valvụ emepe, mgbe ahụ pistin amalite na-akpụ akpụ site n'elu nwụrụ anwụ center. Na usoro nke na-akpụ akpụ ndị agụụ na-guzobere cylinder na anọ na-strok engine na-enweta a ngwakọta nke ikuku na mmanụ ụgbọala Alụlụụ, nke a na-akpọkarị a mmanụ ụgbọala ma ọ bụ mmanụ ụgbọala-air ngwakọta.

Mgbe pistin BDC ga-ebe, n'ihi na adiana nke crankshaft, ọ na-amalite ịrị n'elu nwụrụ anwụ center, nke a na-ewere na mmalite nke mkpakọ ọrịa strok. Nke a na-emechi uzo mmiri valvụ, na ofụri okirikiri, ma valves na-emechi. The combustible ngwakọta nke dị na cylinder na displacement nke pistin ka TDC abịakọrọ, ya okpomọkụ na nsogbu na-abawanye. E nwere a kacha uru mgbe mkpakọ pistin TDC. Ma ebe ọ bụ na mmanụ ụgbọala combustion usoro-ewe oge ụfọdụ maka combustible ngwakọta bụ amụnyewo tupu, tupu pistin esịmde TDC na mkpakọ ọrịa strok. Na ngwakọta bụ amụnyewo site electric icheku ọkụ nke jumps n'etiti electrodes nke plọg. Site n'oge ihe ji BTDC, na crank n'akuku akpọ n'akuku nke precession mgbanye.

Na a ịrịba ama ọtụtụ ndị ike na-ewe, haruru wepụtara n'oge mmanụ ụgbọala combustion, na ịpị na pistin, nke-eme ka engine ịrụ anọ strok okirikiri n'oge ọzọ na-ewere ọnọdụ na valves emechi na pistin ọrịa strok site TDC ka BDC. Iyuzucha strok amalite mgbe ọrịa strok. Ga-, iyuzucha valvụ na pistin eru TDC, displacing iyuzucha ikuku. Mgbe ahụ, na otu usoro okirikiri na-ugboro ugboro.
