Ngenxa yomonakalo onokubakho ngezi njini osuka kwizinto ezifana nokungenwa kwamanzi, ukubola, iindawo eziphumayo okanye ezaphukileyo, kunye neminye imiba engenakubalwa, ukuhlala uphezu kogcino lwakho lwenjini yaselwandle kubalulekile.
Isaci sakudala esithi isikhephe ngumngxuma kumanzi ophosa imali kuwo, sikhona ngesizathu amaphenyane, kwaye iinjini zawo, zibiza kakhulu. Ngokuqinisekileyo kuthatha iipokotho ezinzulu ukuhlawula iinjini zaselwandle eziphezulu kwindawo yokuqala kwaye uzigcine zikwimeko ephezulu.
Ngenxa yomonakalo onokubakho ngezi njini osuka kwizinto ezifana nokungenwa kwamanzi, ukubola, iindawo eziphumayo okanye ezaphukileyo, kunye neminye imiba engenakubalwa, ukuhlala uphezu kogcino lwakho lwenjini yaselwandle kubalulekile. Ngelixa umsebenzi osisiseko womatshini ofunekayo ukwakha injini yaselwandle ngokuyimfuneko iyafana nenjini yeemoto, kulapho ukufana kuphelela khona.
Iinjini zaselwandle zinendawo yokusebenza eyahlukileyo ngokupheleleyo kuneenjini zeemoto. Ngokuqhelekileyo bachitha ixesha labo lokuhamba ngenqanawa okanye kwi-throttle epheleleyo. Isantya sokuhamba ngesikhephe sahluke kakhulu kuneso semoto ehla ngohola wendlela. I-Cruising rpm kuninzi lwezi njini zaselwandle yi-3,500 ukuya kwi-4,000 rpm ngokuxhomekeke kumlinganiselo wokuqhuba kunye nobukhulu beprop. Ngokuthelekisa, i-injini yemoto eqhelekileyo iya kujika kuphela i-1,600 ukuya kwi-2,000 rpm kwizantya zendlela.
I-throttle epheleleyo nayo yahlukile. Nge-injini yaselwandle, igcwele ngokwenene yonke indlela mhlawumbi i-5,500 ukuya kwi-7,500 rpm okanye ngaphezulu ixesha elide (mhlawumbi iiyure), ebeka uxinzelelo oluninzi kwi-injini kunye nabangaphakathi bayo. Uninzi lwentsebenzo yesitrato, umzila wesangqa kunye neenjini zomdyarho wendlela, ngokuthelekisa, zibona kuphela iincopho ze-rpms ngokugqabhuka okufutshane, kwaye zihlala zitshintsha i-rpm njengoko umqhubi evula kwaye ephuma kwi-throttle. Uninzi lweenjini zeemoto zabakhweli azifane zibone icala eliphezulu le-4,500 rpm kwaye zichitha ixesha labo elininzi zingenzi nto okanye zilayisha ngesantya esisezantsi. Ngomdyarho wokutsala kunye neenjini zokutsalwa kweetrektara, i-throttle epheleleyo ihlala kuphela imizuzwana de i-throttle ivaleke kwaye injini ibuyele ezantsi ingasebenzi.
Omnye umahluko obalulekileyo phakathi kwezikhephe kunye neemoto kukuba izikhephe azihambi elunxwemeni. Injini isoloko ityhalela phambili isikhephe. Akukho nkxaso-mali kwaye isikhephe asikwazi ukusebenzisa i-injini ukuqhobosha. Ukuba umqhubi ongenamava ubaleka etyibilika aze ngequbuliso uyeke emke, isikhephe esincinane sinokuntywila ngeempumlo yaye sinokude sijike!
Ubunzima bokubaleka phantsi komthwalo ongaguqukiyo kunye ne-rpm ephezulu kuthetha ukuba iinjini zaselwandle kufuneka zakhiwe zaqina ngenene. Oko akuthethi nto ngaphandle kwezona nxalenye zilungileyo ezifana ne-forged kunye ne-billet cranks, i-forged, i-billet okanye intsimbi yokudibanisa i-pistons, i-pistons edibeneyo, i-ductile iron kunye nentsimbi yentsimbi, iibholiti ze-ARP kunye neentloko zentloko, i-valve yensimbi engenasici, imithombo ye-valve ekumgangatho ophezulu, i-aluminium eyakhiweyo. okanye iiroki zentsimbi, udonga olungqindilili okanye iipushrods ezinkulu, iziphakamisi eziqengqelekayo, kunye netsheyini eqengqelekayo ephindwe kabini okanye iikham zebhanti. Akukho zikona zokusika ukuba ufuna injini yaselwandle ihlale.
Nantoni na esesichengeni samanzi (ingakumbi amanzi anetyuwa) kufuneka ikwazi ukumelana nomhlwa. Oko kuthetha ukuba ii-anodized coatings kwiintloko ze-aluminiyam kunye nee-manifolds zokungena, intsimbi engatyiwa okanye imibhobho yamanzi kunye nezinto zokufakelwa, iiplagi zobhedu okanye zokukhenkcisa, kunye nolunye uhlobo lwepeyinti yaselwandle okanye i-anti-corrosive coating yebhloko, ipani yeoli, izigqubuthelo zevalvu kunye nesigqubuthelo sexesha.
Ngenxa yokuba ii-injini zaselwandle zisebenza nzima ixesha elininzi, zifuna ukupholisa okuninzi. Izikhephe ezisebenzisa ukupholisa amanzi angaphandle zifunxa amanzi kwisixokelelwano sokupholisa ngesango lokungena eliphantsi kwesikhephe okanye kwindawo esemva. Impompo yamanzi eyahlukileyo itsala amanzi kwaye iwahambisa kwimpompo yamanzi yesibini kwi-motor (omatshini okanye umbane). Iimpompo zamanzi kufuneka zibe ne-impellers-resistant-corrosion, iikhava kunye nezindlu.
Ii-manifolds zokukhupha ezipholileyo ngamanzi zisetyenziswa ngeenjini ezininzi zangaphakathi. Isitshintshi sobushushu singasetyenziselwa ukunyusa ubushushu bamanzi angenayo. Ii-manifolds ezipholiswe ngamanzi zikwanceda ukuthintela ukwanda kobushushu kwizikhephe apho ii-injini zikwindawo egqunyiweyo.
Umthwalo oqhubekayo kwi-injini yaselwandle ithetha ukuba ibaleka shushu, nokuba kukho ukupholisa okuninzi. Ubushushu obuninzi bubangela ukwanda kwe-thermal, ngoko ke kuya kufuneka uvumele imvume encinci yepiston-to-cylinder ukunciphisa umngcipheko wokukrazula. I-Ditto yezikhokelo zevalve. Izihlalo zevalvu yokukhupha kufuneka zibe banzi ukuze kudluliselwe ubushushu obungcono, kwaye izihlalo kufuneka zibe yingxubevange yobhedu ukukhuthaza ukudluliselwa kobushushu ngokukhawuleza.
Iingubo ezikhethekileyo nazo zinokunceda ukukhusela umonakalo wokushisa kwiindawo ezibalulekileyo. I-friction yokunciphisa i-anti-scuff coating kwi-piston skirts kunye neebheringi inokubonelela nge-inshurensi eyongezelelweyo, ngelixa ukufudumala ukubonakalisa ukushisa kunye nokukhupha iingubo ezikhuphayo kunokunceda ukulawula ukushisa kwenye indawo kwi-injini.
Ukugcina i-injini yolwandle ilubed ikwangumceli mngeni ngenxa yokushukuma okunyukayo nokuhla okuveliswa ngamaza. Iipani zeoyile kufuneka zomelele kwaye zibe nomthamo omkhulu, ukuze injini ingaphelelwa yioyile. Kukwafuneka ibene-baffles kunye netreyi yomoya ukugcina i-oyile apho ikhoyo. I-oyile epholileyo yangaphandle nayo ibalulekile ukulawula ubushushu, kwaye i-thermostat yobushushu be-oyile idla ngokuba yinxalenye yenkqubo ukuze i-oyile ebandayo ingadlula kwindawo epholileyo kwaye ize ngokukhawuleza kubushushu obuqhelekileyo bokusebenza. Impompo yeoli kunye netyhubhu ye-pickup nayo kufuneka iqiniswe kwaye ityhubhu iboshwe kwimpompo ukuze imelane nayo yonke intshukumo kunye nokubethelwa kwayo kuya kuba nakho.
Kwii-injini zemveliso ephezulu kakhulu (i-1,000 lamandla amahashe okanye ngaphezulu), inkqubo ye-oyile ye-sump eyomileyo idla ngokuba yeyona ndlela ilungileyo yokuqinisekisa unikezelo lwe-oyile rhoqo kwimoto.
Ubomi benkonzo ye-injini yaselwandle bunokususela kwiiyure ezingama-500 ukuya kwezingama-600, ngelixa i-1,000 ye-hp-plus injini inokuba ziiyure ezingama-200 ukuya kwezingama-300 kuphela. Abanye abakhi bee-injini zaselwandle bacebisa ukuba kuhlaziywe imithombo yevalvu kunye neziphakamisi ze-hydraulic roller emva kweeyure ezingama-200 zokusetyenziswa.
Kunyanzelekile ukuba abakhi beenjini zaselwandle bakhe kwaye bakhe ezi njini ngokugqibeleleyo. Ukuba umthengi uchithe nje itoni yemali kwi-injini engazange ibambelele, akayi kuba ngumthengi owonwabileyo okanye umthengi ophindayo.
pYonke into engaphakathi nangaphandle kwezi njini kufuneka ikwazi ukuthatha umothuko wokubaleka nokubetha amaza,q utsho uTyler Crockett kaTyler Crockett Marine Engines. pYonke into kufuneka ibe bubungqina bokungcangcazela kwaye yonke into kufuneka ikhuselwe. Amaxesha amaninzi, siya kubaleka ii-clamps eziphindwe kabini kubasasazi bethu ukuze bangashukumi xa bebetha amanzi arhabaxa, kwaye siqhuba izibiyeli malunga necandelo ngalinye ukuze sikwazi ukuthatha umothuko wokubaleka kwindawo erhabaxa. amanzi.
“Side saya kumabhanti e-v-belt kunye nee-pulleys ezinzulu ngenxa yokuba uhamba kwaye uphuma kwi-throttle emanzini amdaka, oko kwenza ukuba kungabikho ithuba lokuphuma kwebhanti kwaye kukulahlekisele ugqatso. Sikwasebenzisa i-double hose clamps kwimibhobho emininzi yamanzi engundoqo kuba unokwakha uxinzelelo lwamanzi amaninzi xa ungena kwaye uphuma emanzini. Ke ngoko, sineevalvu ezivuthuzayo kwizihluzi zethu zaselwandle kuba uxinzelelo luya kunyuka ngaphezulu kwekhulu leeponti.
“Siphinde senze iicoatings ezininzi ngaphakathi kwee-injini zethu kwaye sifaka neoyile nalapho. Sisebenzisa iioyile zepiston kwaye sisebenzisa inkqubo ye-oiling efakwa entlanjeni ukutshiza ioyile kwizinyusi. Sikwaqinisekisa ukuba sifumana umthamo omkhulu wamanzi nge-injini ukuyigcina ipholile. Ichibi okanye ulwandle lusebenza njengeradiyetha yeenjini zethu. Siphucula ukuhamba kwamanzi ngokusebenzisa impompo yamanzi enemigangatho emibini isondla icala elinye lemoto kunye nelinye inqanaba lempompo kunye nelinye icala lemoto kunye nenqanaba lesibini lempompo.
Ngelixa amanzi enyanzelekile ekusebenzeni ngokufanelekileyo kweenjini zaselwandle, ikwasisizathu sokuqala ezi njini zingena kwimiba kwaye kufuneka zihlaziywe. Amanzi anetyuwa yenye yezona zinto zibangela umonakalo omkhulu kwi-injini.
pIninzi yehla kubasebenzisi bokugqibela kunye nendlela abayigungxula ngayo injini(ii)injini emva kokusetyenziswa ngakunye,q utsho uDarryl Hameetman weHameetman Racing Engines. Ukuyigcina ixhomekeke kubo kwaye abanye abafana balungile ngayo kwaye banethamsanqa ngayo, kunye nabanye abafana, hayi kangako. ”
Ngokutsho kweCrockett, ukubola kwamanzi etyuwa kuya kudla iintloko ze-aluminium kwaye kubangele iingxaki. pSifaka iintloko kwindawo yokusila kwaye ndigalela kwintloko ye-aluminiyam de ndifumane i-aluminiyam ecocekileyo,q utsho. pEmva koko ndawadibanisa onke ndawabuyisela kwakhona.”
Ukunceda amacandelo eenjini zaselwandle alwe ngcono umhlwa kunye nomonakalo wamanzi, uninzi lwabakhi bee-injini basebenzisa ii-coatings kwizakhiwo zabo, ngakumbi kwiipiston kunye neebheringi zokhuseleko olongezelelweyo.
“Kwizinto zokugalela amanzi etyuwa, sambathisa ngaphakathi kwiibhatyi zamanzi ngePromax marine coating. Iigaskets zonke ziyintsimbi engenasici, kwaye umphandle wemoto utshizwe ngepeyinti yokukhusela irust yeMercury.
Xa ii-injini ziza kuhlaziywa, owona msebenzi uxhaphakileyo unxulumene ne-valvetrain okanye unomonakalo wamanzi. Yiloo nto idla ngokuba yiloo nto injini yaselwandle eya kusebenza kuyo ukuba iheader iyaphuka okanye umbhobho womsila uyaqhekeka okanye iivalvu ziqala ukuncamathela kwaye injini iqalise ukutsala amanzi kwakhona.
Ngenxa yokuba ukuqina kwe-injini kunobunzima kakhulu ekusebenzeni kwe-valvetrain, loo ndawo ye-injini kufuneka isebenze kakuhle. I-Tyler Crockett Marine Engines iya kutshintsha ii-lifters kunye ne-valve springs kwiinjini zayo zesikhephe esimnandi malunga neeyure ezingama-250. Kubathengi beqela lomdyarho, ivenkile itshintsha iziphakamisi kwaye ivalvu iphuma rhoqo kwimidyarho emithandathu.
Kuba umnini ngamnye wesikhephe esebenzisa isikhephe sakhe ngokwesiqhelo okwahlukileyo, oku kugcinwa kogcino kuya kwahluka, kodwa kusabalulekile ukwazi ukuba injini yakho iyakufuna nini ukuhlaziya.
pAbanye abafana bayabaleka qho ngeempelaveki, ngoko ke ngokucacileyo kufuneka bahlale phezulu kulungiso lwabo rhoqo kwaye bakhe kwakhona ngokukhawuleza kunomfana obaleka kanye ngenyanga, q utsho uDaryl Hameetman weHameetman Racing Engines. p Nge-1,000 hp, inokufuna ukwakhiwa kwakhona kwiiyure ezingama-250-300. Izinto ezinkulu zamandla ehashe zinokuba ziiyure ezingama-60, kuxhomekeke kwindlela abaqhuba ngayo. ”
Ngokuka-Bob Madara we-Marine Kinetics, ubomi bemithombo yevalvu buxhomekeke kumgangatho wentwasahlobo, ukuphuma kwamandla e-injini kunye nokuba zingaphi iiyure ebaleka ngazo kwinqanawa ukuya kwi-throttle evulekileyo. pA iseti yevalve springs kwi-502 cid motor kufuneka mhlawumbi itshintshwe emva kwe-300 ukuya kwiiyure ezingama-400, nokuba zisajongeka kwaye zivavanywa zilungile," utshilo uMadara. "Kungenxa yokuba imithombo yevalvu inokusilela ngequbuliso ngaphandle kwesilumkiso kwaye ukhuselekile kunokuba uxolo."
Akukho ngxelo yenyani kunoko xa kufikwa kwiinjini zaselwandle. Awufuni kushiywa uxakeke kuba awuzange uzithobele izilumkiso. Abakhi beenjini kufuneka baqinisekise ukuba abathengi beenjini zabo zaselwandle bafumana inkonzo ngamaxesha afanelekileyo, kwaye abanini-zikhitshane kufuneka banxibelelane nabakhi babo ukuqinisekisa ukuba akukho nto ingahambi kakuhle ngexesha elingafanelekanga.
