Muzvidziviriro zvinopisa (zviparadzi) zvemhando dzakawanda, rotors (sliders) ane anti-interference resistors anoshandiswa.Verenga nezve kuti inotsvedza ine resistor chii, ndeapi mabasa ainoita mukupisa, kuti inoshanda sei uye inoshanda sei, pamwe nesarudzo chaiyo uye kutsiva chikamu ichi muchinyorwa.
Chii chinonzi resistor mumhanyi uye ibasa ripi raanoita mukuparadzira moto
Inotsvedza ine resistor ndiyo rotor yeginition dhizaini yekubata uye isina kubata ignition system, yakashongedzerwa nekupindira-kudzvinyirira resistor.
Chero iginition system isimba rine simba rekukanganisa redhiyo iyo inokanganisa kugamuchirwa kwezvirongwa zveredhiyo mumabhendi ese, mumotokari pachayo uye mumotokari inopfuura pedyo.Izvi zvinokanganisa zvinonzwika sekudzvanya uye kuputika, chiyero chekudzokorora chinowedzera nekuwedzera injini kumhanya.Kupindira kunogadzirwa nemagetsi anoitika munzvimbo dzakasiyana-siyana dzeyepamusoro-voltage dunhu reiyo ignition system: mune ma spark gaps e spark plugs uye pakati pevanobatika muvhavha uye inotsvedza yeanogovera.Kana spark inotsvedza, huwandu hwakasiyana hwemagetsi emagetsi anoitika - ndosaka kupindira kuchinzwika paanenge ese mabhendi eredhiyo.Nekudaro, iyo spark pachayo inopa radiation yekudzika kwakadzika, iro simba guru rinoburitswa nezvikamu zvine chekuita ne spark gap - high-voltage waya dzinoita senge antenna.
Kuti urwise chiitiko chakatsanangurwa, zvimwe zvinhu zvinounzwa mune yakakwira-voltage dunhu reiyo ignition system - yakagoverwa kana kuomeswa kupikisa.High-voltage waya ne-non-metallic central conductors dzinoita sekuparadzirwa kwekupikisa.Resistors mune spark plugs uye mune inodhiraivha inotsvedza kuita seyakaomeswa kupokana - iyi tsanangudzo ichakurukurwa mberi.
Sei kuiswa kwemushonga mu-high-voltage circuit kunotungamirira kuderera kwehutano hwekuvhiringidza?Chikonzero chiri nyore.Kana paine kutsemuka kwegomba re spark, high-frequency currents inomhanya nemukondukita akabatana nayo, izvo zvinotungamira mukuburitswa kwemasaisai eredhiyo nemuitisi uyu.Iko kuiswa pakati peiyo spark gap uye conductor yeanopikisa nekupokana kwezviuru zvakati ohms inoshandura mufananidzo: pamwe chete necapacitances uye inductances iyo conductors anogara aine, sefa yakapusa inoumbwa inocheka iyo yakakwirira-frequency chikamu chekuvhiringidza. .Mukuita, kucheka kwakakwana hakuitike, zvisinei, iyo amplitude ye-high-frequency currents muwaya inoderera zvakanyanya, izvo zvinotungamirira kuderera kwakawanda muzinga rekupindira kweredhiyo mu-high-voltage circuit ye ignition system.
Kana isu tichiti zvese zviri pamusoro apa kune inofambisa inotsvedza, saka spark gap pano ndiyo inobatika yevhavha uye yepedyo yekubata inotsvedza, uye iwo akakwira-voltage waya dzinomhanya kubva kucoil kuenda kune inotsvedza uye kubva kune vanobatika kuenda kune makenduru anoita seantenna.Saka, pano resistor iri pakati conductors maviri, asi zvikuru kudzvinyirira kupindira kunoitika pawaya kubva coil, uye kudzvinyirirwa kupindira pamusoro kenduru waya kunoitika nokuda kushorwa waya pachavo uye resistors akavakwa mumakenduru.
Iyo ignition distributor uye nzvimbo ye slider mairi
Ndicho chikonzero chinopikisa ichi chinonzi anti-kupindira (kana kungodzvinyirira).Nekudaro, kunze kwekurwisa kupindira kweredhiyo, chinopikisa chinoita mamwe mabasa akati wandei:
● Kudzivirira (kana kuderedza kusimba) kwekutsva kwekubatana kwechivharo chekugovera uye slider pachayo;
● Kuderedza mukana wekuparara kwemagetsi kubva kune mamwe ma-high-voltage;
● Kuwedzera hupenyu hwebasa remakenduru uye zvikamu zvakabatana;
● Kuwedzera nguva yekubuda kwe spark, iyo mune dzimwe nguva inowedzera kugadzikana kwejini.
Nei zvose izvi zviri kuitika?Chikonzero ndechekupikisa kwemagetsi emagetsi, izvo zvinogadzira resistor.Nekuda kwekupikiswa kweiyo-high-voltage circuit, kana kubuda kunoyerera, simba razvino rinodzikira - zvakakwana kuti spark iri pakati pema electrode emakenduru ibatidze musanganiswa unopisa, asi haina kukwana kunyungudika kwenzvimbo kwesimbi yesimbi. ma electrodes uye vanobatika mune mugovera.Panguva imwecheteyo, simba rakachengetwa mucoil rinoramba rakafanana, zvisinei, nekuda kwekuwedzera kupikisa kwedunhu, harina kupiwa kumakenduru pakarepo, asi kune imwe nguva yenguva - izvi zvinotungamirira pakuwedzera kuburitsa nguva, iyo inogonesa kupisa kwakavimbika kwemusanganiswa mumasilinda.
Nekudaro, imwe chete resistor mune inotsvedza yeignition distributor inoita mabasa akati wandei anowedzera kushanda kweinjini uye kunyaradza kwemota.
Dhizaini uye maitiro eiyo inotsvedza ine resistor
Iyo inotsvedza (rotor) ine resistor ine zvikamu zvakati: kesi yakakandwa, maviri akaomeswa akabatikana (yepakati, akazorora pa ember muvharidziro yevhavha, uye parutivi) uye cylindrical resistor iri munzvimbo yakakosha.Muviri wakagadzirwa nemagetsi ekudzivirira zvinhu, izvo zvinosangana zvinowanzogadziriswa pairi nema rivets.Mahwendefa eSpringy anogadzirwa pane anobatika, pakati peiyo resistor inosungirirwa.Muchikamu chezasi chemuviri unotsvedza, chiteshi chakafananidzirwa chinogadzirwa chekugadzirisa iyo ignition distributor pane shaft.
Zvinoenderana nemaitiro ekuisa resistor, kune marudzi maviri emasiraidhi:
● Nechinhu chinotsiviwa chinopikisa;
● Nechinhu chisingagadziriswi chinopikisa - chikamu chinozadzwa mukati mekuzorora nechinhu chakakosha chekudzivirira chinobva pane epoxy resin kana vitreous zvinhu.
Slider ine resistor
Iwo anomhanya anoshandisa zvine simba resistors eyakakosha dhizaini ine yekupedzisira terminals, yakagadzirirwa kuiswa pakati peiyo springy contacts.Mumotokari dzepamba, zvidziviriro zvinopikisa 5.6 kOhm zvinowanzoshandiswa, zvisinei, zvinopikisa zvinopikisa 5 kusvika ku12 kOhm zvinogona kuwanikwa mumasiraidhi akasiyana-siyana.
Zvichienderana nerudzi rwemugovera, inotsvedza inogona kungogadzikwa pane dhizaini shaft (kazhinji zvikamu zvakadaro zvine T-shaped), kana kugadzikwa nema screws maviri pane ignition timing regulator (zvikamu zvakadaro zvinogadzirwa muchimiro chesilinda cylinder) .Muzviitiko zvese izvi, chinopikisa chakaiswa kunze kwe slider, iyo inovhura mukana wekutarisa kwayo uye, kana zvichibvira, kutsiva.
Mibvunzo yekusarudza uye kutsiva inotsvedza ine resistor
Iyo resistor yakaiswa mu slider inoiswa kune akakosha magetsi uye mekiniki mitoro, saka nekufamba kwenguva inogona kutadza - kupisa kana kudonha (kutsemuka).Sezvo mutemo, kuparara kwemudziviriri hakuregi injini, asi kunokanganisa zvakanyanya kushanda kwayo - injini haina kuwana simba rakazara, inopindura zvisina kunaka kune gasi pedal, "troit", detonates, nezvimwewo. Ichokwadi ndechokuti mazhenje anogona. slip kuburikidza neyakapiswa-kunze kana kupatsanurwa resistor, saka iyo ignition system inoramba ichishanda, asi nekutyorwa uye kushomeka.Kana zviratidzo zvakadaro zvikaonekwa, iwe unofanirwa kutanga wabvisa chivharo chekugovera (izvi zvinofanirwa kuitwa chete kana injini yakamira uye neiyo terminal yabviswa kubva mubhatiri), bvisa uye ongorora slider.Kana iyo inotsvedza iri yakajairika, saka inogona kubviswa isina maturusi, uye kana chikamu chacho chakabatana neiyo ignition timing regulator, ipapo screws mbiri dzinofanira kuburitswa nescrewdriver.
Kana, paunenge uchiongorora resistor, pasina zviratidzo zvekunze zvekushanda kwayo (haina kupiswa kana kuputsika), kana kuti resistor yakazadzwa nekomboni, saka iwe unofanira kutarisa kupikisa kwayo ne tester - inofanira kurara munharaunda ye 5-6 kOhm (kune dzimwe motokari - kusvika 12 kOhm, asi kwete pasi pe5 kOhm).Kana kushorwa kuchiita kusingagumi, ipapo resistor haina kunaka uye inofanira kutsiviwa.Chikamu chemhando imwechete uye kushorwa kunofanirwa kutorwa kuti itsive - iyi ndiyo chete nzira yekuvimbisa kuti resistor ichawira munzvimbo uye iyo yese system inoshanda zvakajairika.Kutsiva chinopikisa kunouya pasi kuti ungobvisa chikamu chekare (zviri nyore kuibvisa ne screwdriver) nekuisa imwe nyowani.Kana iyo resistor yakazadzwa nekomboni, ipapo iwe uchafanirwa kushandura iyo inotsvedza yese - yemotokari dzepamba, kutsiva kwakadaro kunodhura makumi akati wandei eRubles.
Slider ine komboni-yakazadzwa
ResistorReplaceable resistor kune inotsvedza
Kazhinji, varidzi vemotokari vanoisa wire jumpers pane resistors - zvinorambidzwa zvachose kuita izvi.Kusavapo kweanopikisa kunowedzera mwero wekupindira kweredhiyo uye kunogona kukanganisa mashandiro eiyo ignition system (kusanganisira kutungamira mukupfeka kwakanyanya kwevanobatikana neinotsvedza uye yekuparadzira chivharo, uye ma electrode e spark plugs).Izvo zvakare hazvikurudzirwe kushandura inotsvedza ine resistor kune yakapfava inotsvedza mumagetsi masisitimu ane high-voltage waya dze zero resistance.Idzo chete mhando uye mhando dzemasiraidhi anokurudzirwa nemugadziri weiyo ignition distributor ndiyo inofanira kushandiswa kutsiva.
Iine sarudzo chaiyo uye kutsiva iyo inotsvedza ine resistor (kana chete inopikisa), iyo iginition system ichashanda yakavimbika uye ne "kusvibiswa" kushoma kwemhepo yeredhiyo.
