Macheka a unyolo amagwiritsidwa ntchito kwambiri pamakina am'munda podula mitengo mwamakani m'madera akunkhalango ku China, ndipo ma injini awo amadziwikanso kuti injini zoyatsira mkati kapena injini zamafuta. Ndilo gawo lalikulu la chainsaw, lomwe limagwiritsidwa ntchito popanga mphamvu ndikuyendetsa makina ocheka kudzera mu njira yopatsirana podula nkhuni. Injini ya chainsaw ndi yosiyana ndi injini zomwe zimagwiritsidwa ntchito kwambiri pa mathirakitala. The chainsaw ndi awiri sitiroko injini, amene ali kawiri mphamvu ya anayi sitiroko injini.

1. Injini itatha kuyatsa, nthawi zina kuphulika kumachitika, komwe kumakhala kuyaka kwachilendo.

Injini ikaphulika, liwiro la kuyaka kwa lawi limakhala lachangu kwambiri, lomwe limafikira mamita 2000-3000 pamphindikati, pomwe liwiro lakuyaka kwamoto ndi 20-40 metres pamphindikati. Choncho, kutentha kwa injini kumawonjezeka kwambiri, ndipo kupanikizika kwa ma silinda kumawonjezeka kwambiri. Makhalidwe a detonation ndi phokoso lachitsulo chogwedeza mu silinda, kugwira ntchito kwa injini yosakhazikika, kutentha kwambiri, kuchepa kwa mphamvu, ndi utsi wakuda wotuluka paipi yotulutsa mpweya. Chifukwa cha kuwonongeka kwa injini, chuma chake chimasokonekera, mafuta opaka mafuta amawonongeka, komanso amasiya kugwira ntchito kwake, zomwe zimapangitsa kuti achuluke. Chifukwa chake, chodabwitsa cha deflagration sichiloledwa. Chifukwa chachikulu cha kuphulika kwa injini ndi chifukwa cha kuperewera kwa mafuta kapena kuphatikiza kosayenera kwa kalasi yamafuta ndi chiŵerengero cha kuponderezedwa kwa injini. Kuonjezera apo, zimagwirizananso ndi kutentha kwa injini yokha, malo a spark plug, mawonekedwe a chipinda choyaka moto, ndi kukula kwa ngodya yoyatsira pasadakhale. Komanso, ma depositi a kaboni angayambitse kuyatsa ndi kuwonongeka. Kuphulika kumachitika, nthawi yomweyo kutseka valavu throttle (throttle), kuzindikira chifukwa, ndi kuthetsa izo.

2. Kuyatsa patsogolo

Kuyatsa koyambirira kumatanthauza kuti chisakanizo choyaka moto mkati mwa silinda chimayaka chokha popanda kuyembekezera kuyatsa. Chifukwa choyatsira koyambirira ndikuti panthawi yoponderezedwa, kutentha mkati mwa silinda yafika kutentha kwamafuta odziwotcha, kotero sikuyenera kuyatsa ndikuwotcha yokha. Pamene kuyatsa koyambirira kumachitika, injiniyo imatenthedwa, imatulutsa ma carbons ambiri, ndipo injini imagwira ntchito mosagwirizana.

Mwa kusanthula ndi kumvetsa nkhani ziwiri mu njira kuyaka kwa injini, tingathe kumvetsa bwino ntchito ya chainsaw. Pokhapokha podziwa bwino komanso ukadaulo wamakina omwe amatha kugwira ntchito bwino komanso kukhala ndi khalidwe labwino, kukwaniritsa cholinga chopulumutsa anthu ogwira ntchito komanso kuchepetsa ndalama.
