Pamene injini ya petulo ya chainsaw ikugwira ntchito, mafuta amayaka mkati mwa silinda ndipo mpweya wotulutsa mpweya umatulutsidwa mu injini kudzera mu chitoliro chotulutsa mpweya. Mpweya wotuluka wamba ndi wosawoneka ndi maso. Mafuta akapanda kutenthedwa kapena injini sikugwira ntchito bwino, padzakhala ma hydrocarbon, carbon monoxide, nitrogen oxides, ndi carbon particles mu gasi wotuluka mu utsi, ndipo mpweya wotuluka mu mpweyawo umaoneka woyera, wakuda, kapena wabuluu mwachilendo. Titha kuweruza kuyaka kwa petulo kutengera mtundu wa utsi wa injini ndikutenga njira zofananira zothetsera mavuto.
Pamene injini ya petulo ikugwira ntchito, mafuta amayaka mkati mwa silinda ndipo mpweya wotulutsa mpweya umatulutsidwa mu injini kudzera mu chitoliro chotulutsa mpweya. Mpweya wotulutsa mpweya nthawi zambiri umakhala ndi mpweya wamadzi, carbon dioxide, ndi nitrogen. Mpweya wotuluka wamba ndi wosawoneka ndi maso.
Pamene mafuta satenthedwa kapena injini sikugwira ntchito bwino, padzakhala ma hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), ndi carbon particles mu gasi wotuluka, ndipo mpweya wotulutsa mpweya udzawoneka mwachilendo. woyera, wakuda, kapena wabuluu. Titha kuweruza kuyaka kwa petulo kutengera mtundu wa utsi wa injini ndikutenga njira zofananira zothetsera mavuto.
1, Kutulutsa utsi woyera
Utsi woyera mu utsi umapangidwa makamaka ndi tinthu tating'onoting'ono tamafuta kapena nthunzi yamadzi yomwe siinapangidwe mokwanira ndi kutenthedwa. Chifukwa chake, vuto lililonse lomwe limapangitsa kuti mafutawo asakwaniritsidwe kwathunthu kapena kuti madzi alowe mu silinda amapangitsa kuti utsiwo utulutse utsi woyera.
Zifukwa zazikulu za utsi woyera wotulutsidwa ndi injini za petulo za chainsaw ndi izi:
1. Kutentha kumakhala kotsika ndipo kupanikizika kwa silinda sikukwanira, zomwe zimapangitsa kuti mafuta asapitirire bwino, makamaka panthawi yoyamba yozizira pamene utsi woyera umatulutsa utsi;
2. Madzi olowetsa muffler;
3. Madzi ochuluka mumafuta, ndi zina zotero.
Pamene chainsaw iyamba kuzizira, utsi umatulutsa utsi woyera. Ngati utsi woyera utatha injini ikatenthedwa, iyenera kuonedwa ngati yachilendo. Ngati injini ya chainsaw imatulutsa utsi woyera panthawi yogwira ntchito bwino, ndiye kuti ndi vuto. Cholakwikacho chiyenera kuthetsedwa mwa kuyeretsa madzi mu muffler, kusintha mafuta, ndi njira zina.
2, Kutulutsa utsi wabuluu
Utsi wa buluu mu utsi umakhala makamaka chifukwa cha mafuta ochulukirapo omwe amalowa m'chipinda choyaka ndikuchita nawo kuyaka. Chifukwa chake, chifukwa chilichonse chomwe chimapangitsa kuti mafuta alowe m'chipinda choyaka moto chimayambitsa utsi wabuluu kuchokera pakutha.
Zifukwa zazikulu za utsi wabuluu wotulutsidwa ndi injini za chainsaw ndi izi:
1. Valani mphete za pisitoni, kusweka kwa mphete za pisitoni, ndi kuzungulira kwa mphete za pisitoni;
2. Kusonkhana kosayenera kapena kukalamba kulephera kwa zisindikizo za mafuta a valve, kutaya ntchito yosindikiza;
3. Vavu kalozera kuvala;
4. Kuvala kwambiri kwa pistoni ndi makoma a silinda;
5. Injini mbali wokwera kapena inverted;
6. Kutsekeka kwa mpweya;
7. Gulu la mafuta ndilolakwika;
8. Kuchuluka kwa mafuta owonjezera.
Ngati injiniyo ili ndi vuto la utsi wa buluu, chinthu choyamba chimene muyenera kuyang'ana ndicho ngati mafuta mu chainsaw ali odzaza. Kenako, nthawi zambiri ndikofunikira kugawanitsa ndikuwunika makinawo kuti adziwe chomwe chayambitsa ndikuzindikira njira yothetsera vutoli.
3, Kutulutsa utsi wakuda
Ngati chitoliro cha utsi wa chainsaw chimatulutsa utsi wakuda, ndichifukwa chakuti mafuta sanatenthedwe kwathunthu ndipo utsi wa injini uli ndi tinthu tating'ono ta kaboni.
Kuyaka kwathunthu kwa petulo kumafuna chiŵerengero chapadera cha mafuta ndi mpweya kuti zisungidwe mu chipinda choyaka moto. Ngati chiŵerengero cha mpweya m’chipinda choyaka chikachepa kwambiri kapena chakwera kwambiri, chingapangitse injini kutulutsa utsi wakuda. Chifukwa chake, zifukwa zazikulu zomwe injini zazing'ono za petulo za chainsaw zimatulutsa utsi wakuda ndi izi:
1. Mphuno yayikulu ya carburetor yatha;
2. Fyuluta ya mpweya imachepetsedwa kapena kutsekedwa ndi fumbi lambiri, zomwe zimapangitsa kuti musamadye kwambiri komanso kuti musamadye kwambiri;
3. Ntchito yodzaza injini;
4. Mphuno yayikulu ya carburetor imasankhidwa molakwika. Mwachitsanzo, injini ikagwiritsidwa ntchito m'malo okwera kwambiri, chifukwa cha kuchepa kwa okosijeni m'mlengalenga, chopukusira chapadera chapadera chiyenera kusankhidwa, apo ayi chingayambitse utsi wakuda.
Kwa injini zamafuta zomwe zimatulutsa utsi wakuda, kuyang'anira ndi kuthetsa mavuto kungatheke mwa kusintha fyuluta ya mpweya, m'malo mwa mphuno yayikulu, ndikutsimikizira ngati injiniyo yadzaza.
