Iqembu lesimanjemanje lenjini yezimoto lakhiwe ngokuyinhloko umzimba, isilinda head, ikhava yekhanda yesilinda, i-cylinder liner, ikhava enkulu yokuthwala kanye nepani likawoyela. Ukuhlanganiswa komzimba wenjini kubakaki benjini, okuyi-matrix yokuhlanganisa ye-crank connecting rod mechanism, indlela yokusabalalisa ama-valvu, kanye nezingxenye eziyinhloko zesistimu yenjini. Ikhanda le-cylinder lisetshenziselwa ukuvala phezulu kwesilinda futhi kwakhiwe igumbi elivuthayo kanye nomqhele we-piston nodonga lwesilinda.

Ikhanda le-cylinder lisetshenziselwa ukuvala isilinda futhi kwakhiwe igumbi elivuthayo. Ikhanda lesilinda lifakwe ijakhethi yamanzi, imbobo yokungena, imbobo yokuphuma, imbobo ye-spark plug, imbobo yebhawodi, igumbi lomlilo, njll.

I-cylinder block iyindikimba eyinhloko yenjini, ehlanganisa isilinda ngasinye kanye ne-crankcase iyonke. Kuwuhlaka olusekelayo lokufaka ama-pistons, ama-crankshafts, nezinye izingxenye nezinye izinto.

I-cylinder gasket itholakala phakathi kwekhanda le-cylinder kanye ne-cylinder block, futhi umsebenzi wayo ukugcwalisa ama-pores amancane phakathi kwe-cylinder block nekhanda le-cylinder, ukuqinisekisa ukuvaleka okuhle endaweni ehlangene, ngaleyo ndlela kuqinisekiswe ukuvalwa kwegumbi elivuthayo nokuvimbela ukuvuza kwe-cylinder. nokuvuza kwejakhethi yamanzi.

Iqembu le-piston Connecting rod liyingxenye yokudluliselwa kwenjini, edlulisela ukucindezela kwegesi evuthayo ku-crankshaft, okubangela ukuthi ijikeleze futhi ikhiphe amandla. Iqembu lenduku yokuxhuma i-piston lakhiwe ikakhulukazi i-piston, indandatho ye-piston, iphinikhodi ye-piston kanye nenduku yokuxhuma.

Umsebenzi oyinhloko we-piston ukumelana nokucindezela kwegesi evuthayo futhi idlulisele la mandla entongeni yokuxhuma ngephinikhodi ye-piston ukushayela i-crankshaft ukuze ijikeleze. Ngaphezu kwalokho, ingaphezulu le-piston, ikhanda le-cylinder, nodonga lwesilinda ndawonye kwakha igumbi elivuthayo. I-piston iyisakhi esinzima kakhulu enjinini ngaphansi kwezimo zokusebenza, enegesi namandla aphindaphindayo asebenza kuyo.
