Ukunikezwa kukawoyela okungalingani okubangelwa ukwehluleka kwemishini: Ngemuva kokusebenzisa isikhathi eside, ngenxa yezikhala ezivulekile noma ezinkulu kakhulu ekuxhumaneni kwedrayivu kwepompo yomjovo wephethiloli, igiya lokushayela ligugile futhi ukukhuphuka kwangemuva kuyenyuka, okuzophinde kuthinte ukufana ukunikezwa kukawoyela isilinda ngasinye. Ngaphandle kwalokho, ukuvuza kwamalunga wamapayipi kawoyela aphezulu ngenxa yokudlidliza njalo noma ukuqinisa okunganele, namandla okuqinisa ngokweqile kungadala ukuthi insimbi ehlangene iwele futhi ivimbe amapayipi kawoyela, nawo azodala ukuhanjiswa kukawoyela okungalingani kwisilinda ngasinye. Ngaphandle kwalokho, phakathi kwamaphampu okujova uphethiloli neziphethu zombusi, iziphethu ze-plunger yizona ezinamandla amakhulu, ukuguquguquka okukhulu, kanye nemvamisa yokusebenza ephezulu. Ngakho-ke imvamisa yayo yokwephula nayo iphakeme. Umthamo womjovo kagesi osindayo wehlisiwe, ivolumu yokujova uphethiloli wesilinda ngayinye ayilingani, isikhathi sokujovwa ngomjovo kaphethiloli wesilinda ngasinye asibekezelelani, futhi isikhathi sokuqala kwenaliti sikaphethiloli sibambezelekile; uphethiloli osindayo uphakathi noma awukwazi ukuletha.

Ukunikezwa kukawoyela okungalingani ngesikhathi sokulungisa iphutha: Lapho ipompo yokujova uphethiloli isuswe iphutha ebhentshini lokuhlola, ukungalingani kokunikezwa kukawoyela isilinda ngasinye ngejubane elilinganisiwe kufanele kube ngu-3%.

3.Umehluko phakathi kwesimo sokulungisa iphutha nezimo zokusetshenziswa: ipompo yokujova uphethiloli ilungisiwe ebhentshini lokuhlola ekamelweni lokushisa, ngenkathi ukusetshenziswa okufakiwe kusetshenziswa lapho isilinda icindezelwe, izinga lokushisa kusilinda lifinyelela ku-500 ～ 700 ℃, futhi ingcindezi iyi-3 ～ 5MPa. , Lokhu kuhluke impela. Lapho isitimela sisebenza, izinga lokushisa kwepompo yokujova uphethiloli kanye nomjovo kaphethiloli kufinyelela cishe ku-90 ° C, okuzophinde kudale ukuthi i-viscosity kadizili yehle. Ngakho-ke, ukuvuza kwangaphakathi kwe-plunger nomhlangano we-valve valve kuyakhula, futhi inani lokubuyiselwa kukawoyela lingaphezu kwesikhathi sokulungisa iphutha. Ngokwesilinganiso, inani langempela likaphethiloli elifakwe kusilinda ngepompo yokujova uphethiloli lingama-80% kuphela evolumu yokulungisa iphutha yebhentshi lokuhlola. Yize abasebenzi abalungisa iphutha empompini kaphethiloli bezobheka lesi sici, akunakwenzeka ukusiqonda ngokunembile. Ngaphandle kwalokho, ngenxa yokwehluka kwezinga lokugqoka noma lokuqina komoya we-cylinder liner piston kanye nendlela ye-valve, izinga lokushisa nokucindezela kwesilinda ngasinye ngemuva kokuminyaniswa nakho kuzohluka. Noma iphampu yokujova uphethiloli isuswe iphutha ebhentshini lokuhlola, ukuphakelwa kukaphethiloli ngamunye kuzobe kungalingani ngemuva kokufakwa.
