Ndeupi musiyano uripo pakati pe4 sitiroko uye 2 sitiroko injini?

Four-stroke uye maviri-stroke injini dzine zvinhu zvakafanana asi dzinoshanda zvakasiyana. Injini dzechina-stroke dzinowanzo kuwanikwa paSUVs.

Chii chinonzi injini sitiroko?

Mota zhinji nyowani, marori uye maSUV ane injini dzine hupfumi zvakanyanya. Kuti injini ipi neipi ishande nemazvo, inofanira kupedzisa kupisa kwemoto, uko kunosanganisira matsiroro mana akasiyana etambo yekubatanidza nepiston mukati mekamuri rinopfuta muinjini ine-four-stroke injini, kana maviri muinjini ine-two-stroke. Musiyano mukuru pakati peinjini mbiri-stroke uye ina-stroke injini ndeyekupisa nguva. Kangani ivo vanopfura vanokuudza kuti vanoshandura sei simba uye nekukurumidza sei zvinoitika.

Kuti unzwisise musiyano pakati peinjini mbiri, unofanirwa kuziva kuti sitiroko chii. Maitiro mana anodiwa kupisa mafuta, imwe neimwe inosanganisira kutenderera kumwe. Pazasi apa pane mana ega ega sitiroko anobatanidzwa mune mana-sitiroko maitiro.

• Stroke yekutanga ndiyo kunwa Stroke. Injini inotanga pakutora sitiroko apo piston inodhonzwa pasi. Izvi zvinobvumira musanganiswa wemafuta nemhepo kupinda mukamuri inopisa kuburikidza nevhavha yekutora. Munguva yekutanga maitiro, simba rekupedzisa kurovera sitiroko rinopihwa neanotanga mota, inova mota yemagetsi yakasungirirwa paflywheel inotenderedza crankshaft uye inotyaira silinda yega yega.

• Sitiroko yechipiri (simba). Uye vanoti chakawa chinofanira kumuka. Izvi ndizvo zvinoitika panguva yekudzvanya sitiroko sezvo piston inofamba ichidzokera kumusoro kwecylinder. Munguva iyi sitiroko, vharuvhu yekupinda yakavharwa, iyo inomanikidza mafuta akachengetwa uye magasi emhepo sezvo piston inofamba ichienda kumusoro kwekamuri rinopisa.

• Chechitatu sitiroko - kusvirwa. Apa ndipo panosikwa simba. Pangosvika piston pamusoro pehumburumbira, magasi akamanikidzwa anobatidzwa ne spark plug. Izvi zvinogadzira kuputika kudiki mukati mekamuri yekupisa iyo inosundira piston kumashure.

• Yechina sitiroko - pedza. Izvi zvinopedzisa kupisa kwemakumbo mana sezvo piston inosundidzirwa kumusoro netambo yekubatanidza uye vharafu yekuburitsa inovhura uye inoburitsa magasi ekupisa anopisa kubva mukamuri yekupisa.

Sitiroko inoverengerwa serevolution imwe chete, saka kana ukanzwa izwi rekuti RPM zvinoreva kuti kutenderera kuzere kwemotor kana mana akasiyana chinja. Saka, kana injini ichiita 1,000 rpm, zvinoreva kuti injini yako iri kupedza maitiro e-1,000-stroke ka16 XNUMX paminiti, kana kaXNUMX pasekondi.

Musiyano uripo pakati pemaviri-stroke uye mana-stroke injini

Musiyano wekutanga ndewekuti spark plugs anobatidza kamwe chete pakuchinja muinjini ine-maviri uye anobatidza kamwe chete pasekondi shanduko muinjini ine-mavhiri mana. Chimurenga chimwe chezvirongwa zvina. Injini dzechina-stroke dzinobvumira kuti sitiroko imwe neimwe iitike yakazvimirira. Injini ine-two-stroke inoda maitiro mana kuti aitike mukukwira nekudzika kwekufamba, izvo zvinopa mbiri-sitiroko zita rayo.

Mumwe mutsauko ndewekuti maviri-mainjini haadi mavharuvhu nekuti kupinza uye kupera simba chikamu chekumanikidza kwepiston uye kupisa. Pane kudaro, kune chiteshi chekuburitsa mukamuri yekupisa.

Injini mbiri-stroke haina kamuri yakaparadzana yemafuta, saka inofanirwa kusanganiswa nemafuta muhuwandu hwakakodzera. Chiyero chaicho chinoenderana nemotokari uye inoratidzwa mubhuku remuridzi. Zviyero zviviri zvinonyanya kuzivikanwa ndezve 50: 1 uye 32: 1, apo 50 ne 32 zvinoreva huwandu hwepeturu pachikamu chemafuta. Iyo ina-stroke injini ine yakaparadzana mafuta compartment uye haidi kusanganiswa. Iyi ndiyo imwe yedzakareruka nzira dzekutaura mutsauko pakati pemhando mbiri dzeinjini.

Imwe nzira yekuziva vaviri ava ndeyekunzwa. Injini dzine mastroke maviri dzinowanzoita ruzha rwakanyanya, rwepamusoro-soro, nepo injini ine mastroke mana ichiita ruzha rwakapfava. Injini mbiri-stroke inowanzoshandiswa mukugadzira lawn uye yakakwirira-inoshanda kunze-mumugwagwa mota (senge midhudhudhu nesnowmobiles), nepo mana-stroke injini dzinoshandiswa mumotokari dzemumugwagwa uye huru-inotamisa-yakakwirira-injini injini.
