Ngenxa yokuba imowudi yokutsha ye-injini ye-diesel ikukucinywa kwe-ignition, inokubizwa ngokuba yi-injini yokucindezela. Ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini ye-diesel, kufuneka ibe ne-compression ignition eyaneleyo kunye neemeko zokubonelela ngamafutha. Ngentsebenziswano yesitimela sevalve, inkqubo yokubonelela ngamafutha kunye negumbi lokutsha, umxube womoya ococekileyo we-oyile uyenziwa. Ngelo xesha, inkqubo yoxinzelelo kufuneka iqinisekise ukuba ukushisa kunye noxinzelelo kwi-cylinder ekupheleni koxinzelelo ludibana neemeko zokuzitshisa zomxube we-oyile-moya. Ukuba ukucocwa kwevalve kuncinci kakhulu, ukuvuza komoya okanye ukungonelanga kokuqinisa i-torque yeebholiti ze-cylinder head bolts, ukukhululeka, ukonakala kwe-cylinder gasket, ukunxitywa kweringi yepiston kunye nokufakwa kwesamente, ukuvulwa ngengozi kunye nezinye iimpazamo, ubushushu bomoya ocinezelweyo kwigumbi lokutsha aliyi kufikelela. umxube we-oyile-moya. Iqondo lobushushu lokuzitshisa (330 ℃).

2. Ukuqulunqwa komxube ovuthayo kuneemfuno eziqinileyo kumacandelo asebenzayo

Ekubeni ixesha lokwenziwa komxube otshayo we-injini ye-diesel lifutshane kakhulu, i-angle ye-crankshaft imalunga ne-15 ° ukuya kwi-35 ° ukusuka ekuqaleni kokutofa kwe-fuel nge-injector ukuya ekupheleni kokutsha. Ukuze wenze umxube ovuthayo osemgangathweni ngexesha elifutshane kwaye uwutshise ngokupheleleyo, kuyimfuneko ukuthatha amanyathelo afanelekileyo okwakhiwa kwenkqubo yokubonelela nge-injini ye-diesel kunye negumbi lokutsha, kunye nokuqinisekisa umgangatho ophezulu wamafutha.

3. Iimeko zokusebenza ze-cylinder nganye zahluke kakhulu

Iinjini zedizili ezininzi zifuna ukuhambelana kweemeko eziyimfuneko ezifana noxinzelelo loxinzelelo, ubushushu, imeko yokutofa kwamafutha, kunye nomgangatho we-atomization yesilinda nganye. Nangona kunjalo, ngenxa yempembelelo yezinto ezifana nokuchaneka komatshini, isenzo soomatshini, kunye noshintsho lomzimba kunye neekhemikhali, umxube owenziwe yi-cylinder nganye Ukugxininiswa kunye neemeko zokutsha zihluke kakhulu. Xa i-injini ye-diesel isebenza, ithanda ukungasebenzi kakuhle njengokusebenza okungalinganiyo kunye nesantya sokujikeleza esingazinzanga. Ekubeni kukho iindawo ezininzi ze-injini ye-diesel ezifuna ukulungiswa ngesandla, ezifana nokukhutshwa kwevalve, ukuchithwa kwe-decompression, uxinzelelo lwe-injection ye-fuel, ukunikezelwa kwamafutha, njl. iimeko zokusebenza ze-cylinder nganye ukuya kumlinganiselo othile. umahluko.
