Diki-saizi peturu Engine Fuel System
Injini inomhanya chaizvo pamhepo, zvikamu gumi nemana zvemhepo kuenda kune imwe yepeturu.Basa regadziriro yemafuta, saka, nderekutanga kusanganisa, mhepo uye mafuta muzvikamu zvakakodzera uye wozozviendesa kukamuri rinopisa.Iyo carburetor ndiyo chikamu chakakosha.Inovhenganisa mafuta nemhepo, uye mune dzimwe injini duku, inogarawo pombi yemafuta, iyo inotora mafuta kubva mutangi uye inoendesa kune carburetor.
Iyo yakajairika injini diki carburetor ndeye dhizaini yakapusa, yakapusa kureva kuti, kana iwe wakajaira mota carburetor.Kana iwe wakakwanisa kufamba nenzira yako kuburikidza neinjini uye ignition system mashandiro, zvisinei, iwe unogona kunzwisisa carburetion futi.
Tanga nekufunga nezve perfume atomizer.Unosvina girobhu wobva wapfapfaidza pefiyumu.Kana mbiya yacho yaive nepeturu, waiwana musanganiswa wekupfapfaidza wemweya nemadonhwe epeturu.Iyo atomizer inotaridzika yakapusa, asi iwe pamwe hauna kumbofunga nezve mashandiro ayo, saka semupendero bhenefiti yekudzidza nezve diki injini dzegasi, unogona zvakare kunzwisisa iyi boudoir yakakosha.
Neatomizer, kusvina girobhu rinomanikidza mweya kuburikidza nechubhu yakachinjika, inoratidzwa muna 1-17.Izvi zvinogadzira nzvimbo yakaderera-kudzvanywa pamusoro pejeti yechubhu yekubatanidza inodzika ichidzika mupefiyumu.Sezvo mhepo iri mubhodhoro reatomizer pachayo iri pamhepo yakajairika (14.7 pounds per square inch padanho regungwa, zvishoma pakakwirira), inomanikidza inonhuhwirira kukwidza chubhu kuenda kune yakaderera pressure.Ipapo mhepo yemhepo inotora madonhwe uye inoadzinga sepfapfaidzo.
Izvi ndizvo chaizvo zvinonzi carburetor.Asi panzvimbo pepefiyumu, jeti rayo rinotakura peturu.Panzvimbo pokufuridza mhepo kupfuura panogumira jeti negirobhu, kabhureta ine humburumbira ine chimiro chakanyanya inonzi nyanga yemhepo umo injini inoisa vacuum, semuna 1-18.
Iyo miviri-yekutenderera injini inoshandisa vacuum yakagadzirwa mu crankcase kana piston yasimuka.Iyo vacuum inokwevera kuvhura vharuvhu yetsanga uye inokwevera mumhepo kubva kune carburetor nyanga yemhepo kugadzira nzvimbo yakaderera-kudzvanywa ipapo.Sezvo mweya wekunze unopinda mukati kuti uzadze vacuum, unogadzira nzvimbo yakasarudzika yakaderera-inotenderera pamuromo wejeti, ichiburitsa mafuta nenzira yemadonhwe ayo
Inotakura muCrankcase
Iyo ina-kutenderera injini inoshandisa vacuum yakagadzirwa muhumburumbira apo piston inodzika.Panzvimbo yekuyerera mu crankcase, musanganiswa wemhepo-mafuta unoenda zvakananga mucylinder kana vharuvhu yekupinda ichivhura.Kunze kwekusiyana uku, nzira yekupa mafuta kune idzi injini mbiri dzakafanana.Mhepo inoyerera kuburikidza ne carburetor inosarudza huwandu hwemhepo-mafuta musanganiswa iyo injini ichagamuchira.Kuti udzore kuyerera ikoko, kune ndiro yedenderedzwa inonzi throttle, iyo yakasungirirwa pakati penyanga yemhepo.
Paunoshandisa throttle control (kana kutsika gasi pedal mumotokari) unotenderedza ndiro yedenderedzwa ichienda panzvimbo yakatwasuka kuti ubvumire huwandu hwemafuta emhepo-musanganiswa kuyerera.
Izvo zvakakoshawo kuti unzwisise kuti mafuta anosvika sei kune carburetor uye kuti inomisikidzwa sei mujeti.Kune madiki masystem anoita mabasa aya ndiwo akakosha ekufambisa zvikamu mu carburetor uye ari pasi pekutadza.Izvi zvikamu zvinofanirwa kushanda nemazvo, kana zvikasadaro imwe yematambudziko maviri ichaitika:
1) Mafuta mashoma anozopinda mucylinder, uye injini inofa nenzara uye kumira.
2) Kana kuti mafuta akawandisa achapinda, zvichiita kuti injini ifashame yobva yamira.(Huwandu hwakakodzera hwemusanganiswa unoputika uri muchikamu chakamanikana.)
Tangi remafuta ndiro rinogara peturu.Uye mumaseti akareruka akaiswa pamusoro pecarburetor uye akabatana nawo nechubhu.Mafuta anoyerera negiravhiti kubva kutangi kuenda ku carburetor, iyo ine mbiya diki yekuchengeta inokwana kuchengetedza injini ichipihwa kweminiti.Iyi sisitimu inoshanda zvakanaka kune epamba-mhando mowers uye blower.
Imwe dhizaini yakakosha, pamwe yakareruka, ndeye kusimudza carburetor, inoratidzwa muna 1-19.Iyi carburetor ine jeti, tsono inochinjika inopindika mairi (kugadzirisa mafambiro emafuta), kukwenya, kukachidzwa, nyanga yemhepo, uye imwe kana maviri pombi inokweva (“mashanga ekunwira emafuta”) ayo anopinda mukati. tangi yegesi.Iyo vacuum iri mu carburetor nyanga yemhepo inosveta mafuta ehuswa kuburikidza nejeti munyanga yemhepo.
Mune akawanda ma mowers uye blowers, zvisinei, giravhiti yekudya haigoneke nekuti tangi yegesi haigone kukwikwidzwa zvakaringana, uye nyore kusimudza kusimudza hakupe hutongi hwehuni kuti injini ishande zvakanaka pakumhanya kwese. zviitiko izvi zvakanyanya kuoma mafuta ekupomba uye metering masisitimu anoshandiswa.Aya ese ari maviri akavakirwa mumakabhureta painjini diki dzaungangove uine 011 mower yako kana blower.Mune cheni saw, zvakajeka, akasiyana ekushanda ekona anoita kuti giravhiti rekudya dzisashande.Uye kupa mafuta akanaka pasi pemamiriro ese, iyo yakapfava yekusimudza haingave yakanyanya kunaka zvakare.
Pombi ye-on-carburetor ichidimbu chepurasitiki inochinjika mairi inochekwa maHaps maviri ane chimiro cheC anokwira nekudzika achipindura kupuruzira kwevacuum muinjini.Vanovhara uye vanovhura ndima kubva mutangi remafuta uye kune carburetor's mafuta ekutumira system, uko mafuta anoyerwa mumhepo nyanga.Mune mamwe macarburetor, crankcase pressure uye vacuum zvinongofambisa diaphragm-imwe-chidimbu, iyo inokwevera yakavhurika uye inomanikidza kuvharika kwekupinda uye kubuda bhora-mhando vharafu.Iyi dhizaini ine bhora resimbi mune yakasarudzika-yakaita-yakakodzera-ting yakarukwa mupassage.Kana bhora richifambiswa neimwe nzira;inosimbisa nzira;painofambiswa neimwe nzira, mafuta anogona Mapfuura sei.
Kana mafuta ari mu carburetor, imwe yenzira mbiri dzinoshandiswa kudzora kuchengetedza uye metering.Pamamowers akawanda uye ma blower, chinoyangarara chinoshandiswa, senge chakanyorwa mutangi rechimbuzi.Sezvinoratidzwa muna L-20, Hoat ine hinged ine ruoko runoburitsa inodonha kana mwero wemafuta mundiro yecarburetor yakadzikira, zvichibvumira tsono yakatemwa kubva pachigaro chayo, ichivhura nzira inoenda mundiro.Mafuta Makaita sei, zvichiita kuti Kupisa kukwire.Kana Hoat ichisvika padanho rakatarwa, inosundira tsono kumashure kwayo, ichivhara mafuta Sei.Iyo Hoat inochengetedza kukwana kwakakwana uye jet inodhonza kubva kuHoat mbiya inodiwa.
Pamasaha emaketani iyo Hoat systenl haishande, nekuti cheni saha inoshandiswa pamakona akawanda akasiyana zvekuti Hoat yaisazochengeta ndiro yakazadzwa zvakanaka nguva dzese.Pane kudaro, kune Hoatless magadzirirwo ari kushandiswa, ane diaphragm inofambisa tapered tsono vharafu.Kana crankcase inogadzira vacmmi, inokwevera iyo carburetor diaphragm;izvi zvinogadzira vacuum iyo inodhonzawo tsono kubva pachigaro chayo, ichibvumira mafuta kuenda Sei kuburikidza nejeti mumhepo nyanga, kusanganisa nemhepo inovhuvhuta.Sezvinoratidzwa mul-21, diaphragms inogona kushanda nenzira dzakawanda.Onawo L-22 kusvika l-25.
