Elinye icandelo elibalulekileyo lenjini elixhomekeke kumgubo wentsimbi yi-valve seat insertion. Ezi insertions zifakelwa kwiintloko zesilinda ukuxhasa iivalvu zokungenisa kunye nezokukhupha umoya, zinyamezela ubushushu obukhulu obuvela ekutshisweni kunye neempembelelo eziphindaphindiweyo ezivela kwiintshukumo zeevalvu. Amandla omgubo wentsimbi okubunjwa ube bukhulu obuchanekileyo ngokusebenzisa i-powder metallurgy enza ukuba ibe yeyona ifanelekileyo kolu setyenziso. Inkqubo ye-powder metallurgy ibandakanya ukucinezela umgubo wentsimbi kwimo efunekayo ye-valve seat insertion uze uyitshise kumaqondo obushushu aphezulu ukuze yenze inxalenye eqinileyo, ehlala ixesha elide. Le nkqubo iqinisekisa ukuba i-insertion inesakhiwo esilinganayo sengqolowa, ibonelela ngokuchithwa kobushushu okugqwesileyo kunye nokumelana nokuguguleka. Ngokusebenzisa umgubo wentsimbi, abavelisi banokuvelisa ii-valve seat insertions ezilingana kakuhle ngaphakathi kweentloko zesilinda, zinciphisa ingxolo kunye nokungcangcazela ngelixa zigcina ukusebenza kwenjini ngokugqibeleleyo.

Iinkqubo zothumelo, ezithutha amandla ukusuka kwiinjini ukuya kumavili, zixhomekeke kakhulu kwizinto ezenziwe ngomgubo wentsimbi ukuze ziphathe i-torque ephezulu kunye nokuhamba okuqhubekayo. Iiseti zegiya, intliziyo yeenkqubo zothumelo, zihlala ziveliswa kusetyenziswa umgubo wentsimbi ngenxa yokukwazi kwazo ukwenza iiprofayili zamazinyo ezintsonkothileyo ngokuchanekileyo okuphezulu. Iigiya ze-iron powder ziveliswa nge-powder metallurgy, indlela evumela uyilo oluntsonkothileyo ngaphandle kwesidingo somatshini omkhulu. Oku akunciphisi nje ixesha lokuvelisa kodwa kuqinisekisa ukuba izinyo ngalinye legiya linamandla afanayo, kuthintela ukusilela kwangethuba phantsi kwemithwalo enzima. Ukongeza, ubuninzi bendalo be-iron powder bubonelela iigiya ngobunzima obufunekayo ukugcina ukubandakanyeka okuthambileyo, ukunciphisa umva kunye nokuphucula ukusebenza kakuhle kothumelo.

Iipleyiti zeClutch, enye into ebalulekileyo yokudlulisa, nazo ziyazuza kwiimpawu zomgubo wentsimbi. Iipleyiti zeClutch kufuneka zimelane nokungqubana okukhulu xa zidibanisa kwaye zikhupha, zifuna izinto ezimelana nokuguguleka kwaye zinyamezela ubushushu. Umgubo wentsimbi ufakwa kwiipleyiti zeClutch composites, apho usebenza njengezinto zokuqinisa ukuqinisa ulwakhiwo. Amasuntswana omgubo wentsimbi asasazeka ngokulinganayo kuyo yonke i-composite, edala umphezulu omelana nokukrazuka kwaye uchitha ubushushu ngokufanelekileyo. Oku kuqinisekisa ukuba iipleyiti zeClutch zigcina ukusebenza okufanayo nokuba emva kokusetyenziswa okuphindaphindiweyo, kunciphisa umngcipheko wokutyibilika kwaye kwandise ubomi benkqubo yokudlulisa.

Iinkqubo zezixhobo zokuqhuba, ezivumela ulawulo lwezithuthi, zixhomekeke kumgubo wentsimbi ukuvelisa izinto ezinika amandla kunye nokuchaneka.
