Musiyano uripo pakati pekurohwa kaviri-neana-sitiroko injini

Nzwisisa mutsauko pakati pe2 ne4 sitiroko injini, iwe unofanirwa kutanga wanzwisisa mashandisiro anoita ma mota mune zvese.

Saka, kuti injini ishande nemazvo, maitiro emoto anofanirwa kuve akazara. Muna 2-sitiroko uye ina-sitiroko injini, maitiro aya ane mana akapatsanurwa maronda anoitwa nekubatanidza tsvimbo uye pisitoni mukamuri remoto. Chinoita kuti injini mbiri idzi dziparadzane inguva yavo yekuvesa. Kuwanda kwepfuti kwakaridzwa kunoratidza mashandisiro anoita maviri-sitiroko kana mana-sitiroko injini uye nekukurumidza sei kupfura kunoitika.

Inoshanda sei 4-sitiroko injini? Ndeupi musiyano uripo pakati pekurohwa kaviri-neine-sitiroko injini? Tarisa uone tsananguro dzekushanda uye musiyano uripo pakati pemhando mbiri dzeinjini.

4-sitiroko injini

Four-stroke injini injini dzinopisa dzinowanzotangwa nekunze kwesimba sosi se spark plug kana shaker. Kupisa kwavo nekukurumidza kunoshandura kemikari inogona kuita simba iri mumafuta kuita basa remagetsi panguva yekuputika.

Zvinoumba 4-sitiroko injini

Iyi injini ine imwe kana kupfuura sepombi imwe neimwe yadzo ine pfuti inotsvedza ine mutsetse unofamba. Piston yega yega inosimudzwa neimwe nzira uye kudzikiswa uchishandisa tambo yekubatanidza ichibatanidza pisitoni kune crankshaft. Sirinda yega yega inogadzira 4-sitiroko injini yakavharwa neiyi cylinder musoro ine mavhavha maviri:

• Ivhavha yekudyara inopa iyo cylinder pamwe nemhepo-peturu musanganiswa kubva kune yakawanda yekudyira.
• Vhavha yevhavha inoendesa magasi ane flue kuenda kunze nekushandisa chiutsi.

Duty kutenderera kweana-sitiroko injini

Iyo yekushanda kutenderera kweiyo 4-sitiroko injini yakavhiringidzwa ina-sitiroko injini. Nguva yekutanga ndiyo inogadzira simba. Iyi ndiyo nguva iyo kupisa kwemusanganiswa wemafuta nemhepo kunotanga kufamba kwepiston. Iyo yekupedzisira inobva yatanga kufamba panguva yekutanga kusvika imwe injini sitiroko yaburitsa simba rinodiwa kupa dzimwe nguva nhatu dzekushandisa simba pamberi peinjini inotevera sitiroko. Kubva panguva iyoyo, injini inoshanda yega.

Stage 1: yekutanga nhangemutange

Chekutanga kufamba chakaitwa ne4-stroke injini inonzi: "kupinda". Uku ndiko kutanga kweinjini yekuita, semhedzisiro iyo pisitoni inotanga kudzikiswa. Iyo yakaderedzwa pisitoni inokwevera gasi uye nekudaro musanganiswa wemafuta / wemhepo mukamuri yemoto kuburikidza neyevhavha yekudyira. Pakutanga, mota inotangisa yakasungirirwa pawhewhewhe inoshandura crankshaft, inofambisa humbwe yega yega uye inopa simba rinodiwa kupedzisa sitiroko yekudya.

Yechipiri nhanho: kudzvanya sitiroko

Kudzvinyirira sitiroko inoitika apo pisitoni inomuka. Iine vharuvhu yekudyiwa yakavharwa panguva ino, mafuta nemhepo magasi anomanikidzwa mukamuri yemoto kusvika ku30 bar uye 400 uye 500 ° C.

Nhanho 3: moto kana kuputika

Kana pisitoni ikakwira yosvika pamusoro pesilinda, kumanikidza kuri padanho repamusoro. Spark plug yakabatana neepamusoro voltage jenareta inobatidza gasi rakamanikidzwa. Iyo inotevera inokurumidza kupisa kana kuputika padzvinyiriro ye40 kusvika 60 bhaa inosundira iyo pisitoni pasi uye inotangisa kumashure nekudzoka kufamba.

Kurohwa kwechina: kupera

Iko kuneta kunopedzisa mana-sitiroko kupisa maitiro. Piston inosimudzwa netsvimbo yekubatanidza uye inosundira magasi akatsva kunze. Vhavha yekudzimisa inozovhurwa kuti ibvise magasi akatsva kubva mukamuri yemoto kuitira muripo mutsva wemusanganiswa wemhepo / mafuta.

Ndeupi musiyano uripo pakati peanonzi 4-stroke engines uye 2-stroke engines?

Kusiyana neina-sitiroko injini, 4-sitiroko injini shandisa mativi maviri - kumusoro uye pasi - yepiston... Yekutanga ndeye yekumanikidza uye kupisa zvikamu. Uye yechipiri ndeyekutapurirana kwemweya wekutora uye wekuzadza. Nekudzivirira kufamba kwemaviri macircuit esimba, anogadzira torque uye simba.

Zvikamu zvina muchikamu chimwe chete

Mune injini yekurova-mbiri, spark plugs moto kamwechete pa chimurenga. Izvo zvikamu zvina zvekudya, kumanikidza, kupisa uye kupedza zvinoitwa mukufamba kumwe kubva kumusoro kusvika pasi, ndosaka zita iri maviri-sitiroko.

Hapana vharafu

Sezvo kudya uye kupera chiri chikamu chekumanikidza uye kupisa kwepiston, maviri-sitiroko injini haina vharafu. Dzimba dzavo dzekutsva dzakagadzirwa neinobuda.

Mafuta akasanganiswa uye mafuta

Kusiyana neina-sitiroko injini, 4-sitiroko injini hadzina maviri akakosha makamuri einjini oiri uye mafuta. Ose ari maviri akasanganiswa mune chimwe chikamu mune inoenderana yakatsanangurwa huwandu.
