I-Mazda R2 iyinjini yakudala ene-four-stroke prechamber enamandla angu-2.2 litres futhi isebenzisa injini kadizili. Yakhelwe ngokukhethekile izimoto ezisindayo. Ihlukaniswa ngokuthembeka kwayo nempilo ende yenkonzo.

ICE R2

Izici zobunjiniyela

Iyunithi yamandla asemoyeni i-R2 yathuthukiswa maphakathi nawo-XNUMX ekhulwini elidlule lamaloli.

Le njini inamasilinda amane ahlelwe umugqa owodwa, i-direct valve drive kanye ne-camshaft etholakala phezulu. I-cylinder ngayinye ine-valve eyodwa yokukhipha kanye ne-exhaust.

Iphinde ifakwe nephampu yokusabalalisa uphethiloli elawulwa ngomshini, nakuba abathuthukisi bahlomise amamodeli e-Kia Sportage ngephampu yomjovo elawulwa ngogesi. Lolu hlobo lwepompo lubonakala ngokubumbana, ukunikezwa okufanayo kwamafutha kumasilinda nokusebenza okuhle kakhulu ngesivinini esikhulu. Igcina ingcindezi edingekayo ohlelweni kuye ngendlela yokusebenza kwenjini.

Iphampu yomjovo R2

Kufakwe i-crankshaft enama-counterweights ayisishiyagalombili. Ibhande elinamazinyo lisetshenziselwa ukushayela indlela yokusabalalisa igesi.

Umklami wasebenzisa i-piston emfushane, eyandisa ivolumu. I-cylinder block ye-linerless eneziteshi zamafutha ezimise okwesiphambano, ezenziwe nge-cast iron, iqinile kakhulu, kodwa ngesikhathi esifanayo inezela isisindo kuyunithi. Amakhanda e-cylinder enziwe nge-aluminium alloy, enomthelela omuhle emandleni nokusebenza kwezomnotho kwenjini. Inzwa yesikhundla se-camshaft itholakala ngaphansi kwekhava. Ukukhishwa okushisayo kwama-valve kulungiswa kusetshenziswa ama-washers.

I-R2 inikeza umjovo wangaphambi kwekamelo, okungukuthi, uphethiloli ungena kuqala ekamelweni langaphambili, elixhunywe ku-cylinder ngamashaneli amancane amaningana, livutha lapho bese lingena ekamelweni eliyinhloko lomlilo, lapho lishisa khona ngokuphelele.

Esinye sezici ezibaluleke kakhulu zenjini ukwakheka kwama-pistons, okuhlanganisa ukufakwa okukhethekile okunciphisa ukushisa okuvimbela ukwanda okweqile kwe-duralumin futhi ngaleyo ndlela kunciphise igebe phakathi kwezindawo ze-cylinder kanye ne-piston.

Ishafti yenjini evuthayo yangaphakathi ifakwe isidambisi-manzi esishintshashintshayo esithuthukisa izici zokusabalalisa igesi.

Okunamathiselwe kwenjini kuqhutshwa ngokwengxenye yibhande lesikhathi.

I-Mazda R2 inesistimu yokupholisa umoya evaliwe ene-circulation epholisayo, ehlinzekwa yiphampu ye-centrifugal.

Izinzuzo nokungalungi

Enye yezinkinga eziyinhloko zenjini ye-diesel eveziwe yikhanda le-cylinder, ngaphakathi lapho ukuqhekeka kwakha ngenxa yokushisa ngokweqile. Ukuhlonza lesi sici kuyinkinga; ukubukeka kwayo kuboniswa ukushisa okukhulu kwenjini ngesikhathi sokusheshisa.

Ezindaweni eziningi zezwe lethu, i-cylinder head kanye nezinye izakhi ze-R2 kunzima ukuthola, ngakho-ke amakhanda avela ku-RF-T noma i-R2BF motor avame ukusetshenziselwa yona.

Kunzima kakhulu ukushuna i-R2 uwedwa, cishe uzodinga usizo lochwepheshe.

Inzuzo yeyunithi ilele ekwakhiweni okungavamile kwama-piston kanye nayo yonke induku yokuxhuma neqembu le-piston. Ilungele iloli lomsebenzi noma iveni elincane ngoba inamandla amaningi futhi inetorque esezingeni eliphansi. Injini ayakhelwe ukuhamba ngesivinini esikhulu.

Ukuwohloka okukhulu

"R2" iyinjini enokwethenjelwa futhi ayijwayele ukuphuka njalo, kodwa izinkinga ziyenzeka ngayo:

Iyeka ukuqala ngenxa yokungasebenzi kahle kwama-injection noma ukungasebenzi kahle kwepompo likaphethiloli nama-spark plugs;
Ukugqoka izakhi zesikhathi noma ukugeleza komoya okungena ohlelweni lokunikezela uphethiloli kuholela ekusebenzeni kwayo okungazinzile;
Umusi omnyama uvela ngenxa yokucindezelwa okuphansi, ukwehluleka kwentwasahlobo ye-nozzle noma ukuqhuma kwenaliti ku-nozzle;
Imisindo yokungqongqoza engaphandle ivela uma izinga lokucindezela lingahambisani namanani ashiwo, noma ngenxa yokujova kwangaphambi kwesikhathi kwengxube evuthayo, noma ukuguga kwezinto ze-ShPG.

"R2" inokugcinwa okuhle, kodwa njengoba sekushiwo kakade, izingxenye zayo akulula ngaso sonke isikhathi ukuthola, ngenxa yalesi sizathu kufanele uboleke kwezinye izinjini, isibonelo, ku-Mazda RF, R2AA, noma i-MZR-CD.

Ukulungisa u-R2

Isondlo

Ukugcinwa kokuqala, ngokusho kwemithethonqubo, kwenziwa ngemva kwamakhilomitha ayizinkulungwane ezingu-10. Ngesikhathi esifanayo, uwoyela wenjini uyashintshwa, kanye nesihlungi samafutha nomoya, ukucindezela kweyunithi kuyalinganiswa futhi ama-valve alungiswa.

Ngemuva kwe-20 km, ukulungiswa kwesibili kwenziwa, okuhlanganisa ukuxilonga zonke izinhlelo zenjini nokushintsha isihlungi sikawoyela nophethiloli.

Ukugcinwa kwesithathu (emva kwezinkulungwane ezingu-30 km) kuhilela ukufaka esikhundleni se-coolant kanye nesihlungi samafutha, ukuqinisa ama-bolts ekhanda le-cylinder.

Ibhande lesikhathi kumele lishintshwe njalo ngemuva kuka-80 000 km, kungenjalo lizophuka ligobe ama-valve.

Ama-injection adinga ukushintshwa minyaka yonke, ibhethri, i-antifreeze namapayipi kaphethiloli ahlala iminyaka emi-2. Amabhande okunamathisela ayaguga ngemva kweminyaka emibili nengxenye. Isistimu yokujikeleza kabusha kwegesi ephumayo kufanele ibuyekezwe njalo eminyakeni emine.
