Kusiyana pakati pa sitiroko zinayiotchetcha udzundi makina awiri otchetcha udzu

Stroke imatanthawuza maulalo omwe injini imadutsamo panthawi yogwira ntchito. Mikwingwirima inayi imatanthauza kuti imadutsa maulalo anayi. Mikwingwirima iwiri yofananira imadutsa maulalo awiri. Kusiyanitsa kwakukulu pakati pa makina opangira udzu wothira udzu ndi mikwingwirima iwiri ndikuti mapangidwe a injini yazitsulo zinayi ndizovuta kwambiri, ndipo ntchito yazitsulo ziwiri ndizopambana pazikhalidwe zomwezo. Injini yokhala ndi mikwingwirima iwiri ndiyopepuka, imakhala ndi ndalama zochepa zopangira, ndipo imakhala ndi kulephera kochepa. Kunena zoona, injini ya sitiroko inayi imakhala yaphokoso. Ubwino wa makina otchetcha udzu wokhala ndi mikwingwirima inayi ndipamwamba kwambiri, kugwiritsa ntchito bwino, kuteteza madzi ndi nthaka, ndi zina zotero. Tiyeni tiwone zomwe zili pansipa.

Kodi makina otchetcha udzu wa petulo wa sitiroko zinayi ndi chiyani?

Makina otchetcha udzu wamafuta anayi amatanthauza kuti mikombero iwiri iliyonse ya makina otchetcha udzu, imadutsa mikwingwirima inayi ya kudya, kukakamiza, mphamvu, ndi utsi kuti amalize kugwira ntchito, pomwe chotchetcha udzu wofanana ndi zikwapu ziwiri zokha. imafuna crankshaft kuti izungulire. Mlungu umodzi ndi zikwapu ziwiri zimatha kumaliza ntchito. Zikwapu zinayi zimasiyana ndi zikwapu ziwiri potengera powertrain.

Kusiyana pakati pa makina otchetcha udzu okhala ndi sitiroko anayi ndi makina awiri otchetcha udzu

1. Kapangidwe

Kuchokera pamalingaliro, kapangidwe ka injini yotchetcha udzu wokhala ndi mikwingwirima iwiri ndi yosavuta. Amapangidwa makamaka ndi mutu wa silinda, silinda, pisitoni, mphete ya pisitoni ndi mbali zina. Pali mabowo olowetsa mpweya, mabowo otulutsa mpweya komanso mabowo olowera mpweya pa thupi la silinda. ;Kutsegula ndi kutseka kwa dzenje la mpweya kumatsimikiziridwa ndi malo a pistoni. Poyerekeza ndi injini ya makina otchetcha udzu wokhala ndi mikwingwirima inayi, palibe makina ovuta a valve ndi makina opaka mafuta. Makina ozizirira nthawi zambiri amakhala oziziritsidwa ndi mpweya, ndipo mawonekedwe ake amakhala osavuta.

2. Kachitidwe

Liwiro la crankshaft likakhala lofanana, kuchuluka kwa nthawi yomwe injini ya makina otchetcha udzu imagwira ntchito pa nthawi ya unit ndi kuwirikiza kawiri kuposa injini ya sitiroko zinayi. Mwachidziwitso, mphamvu ya injini ya sitiroko iwiri iyenera kukhala yowirikiza kawiri ya injini ya sitiroko inayi (koma kwenikweni ndi nthawi 1.5 mpaka 1.7). Injini imakhala ndi mphamvu zambiri pa lita imodzi, mphamvu yabwinoko, komanso kugwedezeka kwa injini yaying'ono. Kuphatikiza apo, injini zokhala ndi sitiroko ziwiri ndizopepuka, zotsika mtengo kupanga, zolephera zocheperako, ndizosavuta kuzisamalira, ndizosavuta komanso zosinthika kugwiritsa ntchito.

3. Nthawi zofunsira

Ma injini a sitiroko anayi amagwiritsidwa ntchito kwambiri, ndipo magalimoto ambiri ndi makina omanga amakhala ndi mainjini a sitiroko anayi. Ma injini a sitiroko awiri amagwiritsidwa ntchito nthawi zambiri pamene chiŵerengero cha thrust-to-weight ndi chofunikira. Mwachitsanzo, makina otchetcha udzu, macheka a unyolo, ndege zachitsanzo, makina olima, ndi zina zotero. Ngati mukukolola mbewu zofewa, ndi bwino kusankha makina otchetcha udzu wa mikwingwirima inayi kuti zokololazo zikhale zaudongo komanso zosavuta kugwiritsa ntchito.

4. Phokoso

Ngakhale kuti mitundu yonse iwiri ya makina otchetcha udzu imakhala yaphokoso, tikulankhula motere, makina otchetcha udzu a 4 siphokoso kwambiri kusiyana ndi makina otchetcha udzu aŵiri.

Ubwino wa makina otchetcha petulo a sitiroko anayi

1. Mkulu lachangu

Nthawi zambiri, makina otchetcha mafuta a petulo anayi aliwonse amatha kudula udzu wopitilira 8x667 masikweya mita patsiku, ndipo mphamvu yake imakhala yofanana ndi nthawi 16 kuposa kupalira pamanja.

2. Zopindulitsa zabwino

Chifukwa cha kuthamanga kwachangu kwa makina otchetcha udzu, kudulidwa kwa namsongole pamunda wa zipatso ndikwabwino, makamaka kudula kwa namsongole ndi kukoma mtima kwakukulu ndikwabwinoko. Nthawi zambiri, kupalira kumachitika katatu pachaka kuti akwaniritse zofunikira pakupalira.

3. Sungani madzi ndi nthaka

Kupalira pamanja ndi khasu nthawi zambiri kumapangitsa kuti madzi achuluke komanso kukokoloka kwa nthaka chifukwa dothi lapamwamba limamasuka popalira. Kupalira pamanja pamakwerero kungayambitse kukokoloka kwa madzi ndi nthaka. Kugwiritsa ntchito makina otchetcha udzu ku udzu kumangodula mbali zomwe zili pamwamba pa udzu ndipo sizikhudzanso nthaka. Kuonjezera apo, kukonzanso nthaka kwa mizu ya udzu kumapindulitsa kwambiri kusunga madzi ndi nthaka.

4. Wonjezerani chonde

Mukamagwiritsa ntchito makina otchetcha udzu, dikirani mpaka namsongole atakula mpaka kutalika kwake. Udzu wochuluka wodulidwa ukhoza kuphimba munda wa zipatso ndipo ukhoza kugwiritsidwa ntchito ngati feteleza wachilengedwe m'munda wa zipatso kuti uwonjezere chonde m'nthaka.
