Chithunzi 6, Chithunzi 7 ndi Chithunzi 8 chikuwonetsa kuti, nthawi ya jekeseni ikafupikitsidwa, kuyatsa

nthawi yochedwa imafupikitsidwa pang'ono ndipo malo oyambira kuyaka apita patsogolo. Kuchuluka kwa kutentha kwa kutentha kwapamwamba kumakhala kokwera kwambiri, ndipamene gawo lofananira limakhalira. Pamene kuthamanga kwakukulu kwa kuyaka kukuwonjezeka, gawo lolingana ndilopita patsogolo. Pamene kutentha kwapakati pa silinda kumawonjezeka, gawo lofananiralo limapita patsogolo koma kutentha kwapakati pa silinda panthawi yoyatsira kumachepetsedwa pang'ono. Kutulutsidwa kwa kutentha kwakuya kumakhazikika, kutulutsidwa kwa kutentha komwe kumasokonekera kumakhala kofanana, koma kutulutsa kwa NO kumawonjezeka kwambiri.13

Pamene jekeseni yoyambira imasungidwa pa 352 ° CA, ndi nthawi yayifupi ya jekeseni, mafuta

Kupopera mu silinda kumawonjezedwa kupyolera mu ngodya yomweyi ndipo mtunda wolowera ukuwonjezeka.14 Izi zimachititsa kuti mafuta asakanizedwe ndi mpweya ndi atomization yabwino yamafuta, kotero kuti nthawi yochedwa kuyatsa imafupikitsidwa, kuyaka kosakanizika kwamafuta kumachepetsedwa. kuchuluka, ndipo kuyaka kufalikira kumafika mwachangu. Zotsatira zake, kutulutsa kutentha kwakuya kumachulukira, kuthamanga kwa kuyaka ndi kutentha kwa silinda kumawonjezeka, ndipo NO kupanga kumawonjezeka moyenerera15. Chithunzi 9 chikuwonetsa gawo la dizilo lomwe latengedwa kuchokera pamtanda pamtunda wofanana ndi bowo la mphuno pa 380 ° CA. Zitha kupezeka kuti nthawi ya jekeseni ikafupikitsidwa, kuyaka kumayamba kale ndipo kumakhala kokhazikika; kuonjezera apo, gawo lotsalira la dizilo limachepetsedwa pa 380 ° CA ndipo gawo la pambuyo pa kuyaka limachepetsedwanso. Izi ndi conductive ku kusintha kwamphamvu mphamvu.
