Kusiyana pakati pa chodulira burashi cha ma stroke anayi ndi chodulira burashi cha ma stroke awiri

Kusiyana pakati pa stroke zinayi makina odulira udzu ndi makina odulira udzu okhala ndi mikwingwirima iwiri

Kugundana kumatanthauza maulalo omwe injini imadutsamo panthawi yogwira ntchito. Kugundana kwachinayi kumatanthauza kuti imadutsa maulalo anayi. Kugundana kwachiwiri kofananako kumadutsa maulalo awiri. Kusiyana kwakukulu pakati pa makina odulira udzu a four-stroke ndi makina odulira udzu a four-stroke ndi kwakuti kapangidwe ka injini ya four-stroke ndi kovuta kwambiri, ndipo magwiridwe antchito a makina odulira udzu a four-stroke ndi abwino kwambiri pamikhalidwe yomweyi. Injini ya four-stroke ndi yopepuka, ili ndi ndalama zochepa zopangira, ndipo ili ndi chiwopsezo chochepa cha kulephera. Ponena za izi, injini ya four-stroke siili ndi phokoso lochepa. Ubwino wa makina odulira udzu a four-stroke ndi wothandiza kwambiri, wothandiza bwino, wosamalira madzi ndi nthaka, ndi zina zotero. Tiyeni tiwone chidziwitso chofunikira pansipa.

Kodi makina odulira udzu a petulo anayi ndi chiyani?

Chotsukira udzu cha petulo anayi chimatanthauza kuti ma cycles awiri aliwonse a injini ya chotsukira udzu, chimadutsa ma strokes anayi a intake, compression, power, ndi exhaust kuti chimalize ntchito, pomwe chotsukira udzu cha ma strokes awiri chimangofuna kuti crankshaft izungulire. Sabata imodzi ndi ma strokes awiri amatha kumaliza ntchito. Ma strokes anayi amasiyana ndi ma strokes awiri pankhani ya powertrain.

Kusiyana pakati pa makina odulira udzu okhala ndi zipolopolo zinayi ndi makina odulira udzu okhala ndi zipolopolo ziwiri

Kusiyana pakati pa makina odulira udzu okhala ndi zipolopolo zinayi ndi makina odulira udzu okhala ndi zipolopolo ziwiri

1. Kapangidwe

Poganizira kapangidwe kake, kapangidwe ka injini yodula udzu yokhala ndi magawo awiri ndi kosavuta. Imakhala ndi mutu wa silinda, silinda, pisitoni, mphete ya pisitoni ndi zina. Pali mabowo olowera mpweya, mabowo otulutsa utsi ndi mabowo opumira mpweya pa thupi la silinda. ;Kutsegula ndi kutseka kwa dzenje la mpweya kumatsimikiziridwa ndi malo a pisitoni. Poyerekeza ndi injini ya makina odula udzu okhala ndi magawo anayi, palibe njira yovuta yogwiritsira ntchito ma valavu ndi njira yothira mafuta. Makina oziziritsira nthawi zambiri amakhala ozizira ndi mpweya, ndipo kapangidwe kake kamakhala kosavuta kwambiri.

2. Magwiridwe antchito

Ngati liwiro la crankshaft ndi lofanana, kuchuluka kwa nthawi zomwe injini ya makina odulira udzu opangidwa ndi zipolopolo ziwiri imagwira ntchito pa unit time kumakhala kawiri kuposa kwa injini ya ma stroke anayi. Mwachidziwitso, mphamvu ya injini ya ma stroke awiri iyenera kukhala kawiri kuposa ya injini ya ma stroke anayi (koma kwenikweni ndi nthawi 1.5 mpaka 1.7 zokha). Injiniyo ili ndi mphamvu zambiri pa lita imodzi, mphamvu yabwino, komanso Injini Yaing'ono Kugwedezeka. Kuphatikiza apo, mainjini a two-stroke ndi opepuka kulemera, otsika mtengo kupanga, ali ndi kulephera kochepa, ndi osavuta kusamalira, ndipo ndi osavuta kugwiritsa ntchito komanso osinthasintha.

3. Nthawi zofunsira ntchito

Mainjini a ma stroke anayi amagwiritsidwa ntchito kwambiri, ndipo magalimoto ambiri ndi makina omanga amakhala ndi mainjini a ma stroke anayi. Mainjini a ma stroke awiri amagwiritsidwa ntchito kwambiri pamene chiŵerengero cha kugundana ndi kulemera n'chofunika. Mwachitsanzo, makina odulira udzu, Chocheka cha Unyolos, ndege zachitsanzo, makina a pafamu, ndi zina zotero. Ngati mukukolola mbewu zofewa, ndi bwino kusankha chotsukira udzu cha mikwingwirima inayi kuti zokololazo zikhale zoyera komanso zosavuta kugwiritsa ntchito.

4. Phokoso

Ngakhale kuti mitundu yonse iwiri ya makina odulira udzu imakhala ndi phokoso pang'ono, makina odulira udzu okhala ndi zipolopolo zinayi samakhala ndi phokoso kwambiri kuposa makina odulira udzu okhala ndi zipolopolo ziwiri.

Ubwino wa makina odulira udzu a petulo anayi

1. Kuchita bwino kwambiri

Kawirikawiri, chotsukira udzu chilichonse cha petulo cha petulo cha 4-stroke chimatha kudula udzu woposa 8×667 square metres patsiku, ndipo mphamvu yake ndi yofanana ndi kuchulukitsa nthawi 16 kuposa udzu wamanja.

2. Ubwino wabwino

Chifukwa cha liwiro lozungulira la makina odulira udzu mwachangu, zotsatira zake pa udzu wa m'munda ndi zabwino, makamaka zotsatira zake pa udzu wofewa kwambiri zimakhala bwino. Nthawi zambiri, kupalira kumachitika katatu pachaka kuti akwaniritse zofunikira pa kupalira.

3. Sungani madzi ndi nthaka

Kuchotsa udzu ndi khasu nthawi zambiri kumayambitsa madzi ndi nthaka kukokoloka chifukwa nthaka yapamwamba imamasuka pamene mukuchotsa udzu. Kuchotsa udzu ndi dzanja pa makwerero kungayambitse madzi ndi nthaka kukokoloka kwambiri. Kugwiritsa ntchito makina odulira udzu pochotsa udzu kumadula udzu womwe uli pamwamba pa nthaka ndipo sikukhudza kwambiri nthaka. Kuphatikiza apo, mphamvu yokonza nthaka ya mizu ya udzu ndi yothandiza kwambiri pakusunga madzi ndi nthaka.

4. Wonjezerani chonde

Mukagwiritsa ntchito makina odulira udzu kuti muchotse udzu, dikirani mpaka udzu utakula kufika pa msinkhu winawake. Udzu wambiri wodulidwa ukhoza kuphimba munda wa zipatso ndipo ungagwiritsidwe ntchito ngati feteleza wachilengedwe m'munda wa zipatso kuti uwonjezere chonde m'nthaka.
