Izinto ezisemqoka zokuhlanza ingcindezi ephezulu ngokuvamile zakhiwa ngesakhiwo sepompo yeplunger. Kunamakholomu amaningi e-ceramic noma amakholomu ensimbi e-tungsten ngaphakathi. I-motor ixhunywe yi-crankshaft noma i-eccentric disk ukuguqula ukujikeleza Umzimba we-cylinder ifakwe i-valve eyodwa, futhi inqubo yokusakazwa kwamanzi okungena-ukucindezela-amanzi akhiwa ngokucindezela kwenduku ye-piston. Kule nqubo yomjikelezo.

Uma ufuna ukukhuphula umfutho ophuma emanzini, udinga ukushintshanisa i-valve elawula ingcindezi. Ingcindezi elawula i-valve icindezela ikholomu yokufaka uphawu esilinganisweni samanzi ngentwasahlobo yangaphakathi yengcindezi enkulu. Vula, ukhiphe uketshezi olunengcindezi ephezulu, bese ugcine ingcindezi isezingeni lomgodi. Sincoma ukuthi uyisebenzise ngaphakathi kwengcindezi elinganisiwe, ngaphandle kwalokho izosheshisa ukugqokwa kwezingxenye zepompo futhi ibangele ukuthi imoto ishise ngokweqile, okuzothinta impilo yepompo futhi kubangele nomonakalo ongalungiseki.

Ukuthola eminye imininingwane yezobuchwepheshe mayelana ne-washer yengcindezi, sicela uxhumane nathi futhi sizobe sikusiza nganoma yisiphi isikhathi.
