ʻO nā ʻāpana kaʻa kahi huahana e hoʻokumu i kēlā me kēia ʻāpana o ke kaʻa holoʻokoʻa a lawelawe i ke kaʻa. Nui nā ʻano ʻāpana kaʻa, me ka hoʻomaikaʻi ʻana o ka nohona o nā kānaka, ke piʻi nui nei ka ʻai ʻana i nā kaʻa, a ke ulu nei ka mākeke o nā ʻāpana kaʻa. I nā makahiki i hala iho nei, ke ulu wikiwiki nei nā mea hana ʻāpana kaʻa. ʻO ka mea mua, ka hoʻāʻo ʻana i ka hoʻopaʻa ʻana i ka cylinder
ʻEhiku mau mea e pili ana i ka hoʻopaʻa ʻana o ka cylinder, ka nui o ka cylinder wear, piston ring damage, piston wear, valve seat damage, valve guide wear, cylinder gasket damage, valve clearance a me nā mea ʻē aʻe o ka pilikia.
He aha nā ʻano diagnostic maʻamau? ʻO ke ana nui o ka cylinder pressure, crankcase gas channelby, cylinder leakage a me ka leakage rate, intake pipe vacuum, cylinder piston group ma muli o ka nui o ka ʻaʻahu ma muli o ke ana ʻana o ka vibration abnormal, crankcase wear metala ka hoʻoholo ʻana o ka ʻikepili.
No ke ana o ka puʻe puʻe cylinder, ʻo ia ka nui o ke kaomi ʻana ma ka pau ʻana o ka hoʻoemi ʻehā-stroke engine. Ma muli o ke kaomi cylinder a me ka viscosity o ka aila a me ka hui piston cylinder, ua pololei ka hoʻoponopono ʻana o ka mīkini valve, ke sila ʻana o ka cylinder pad a me nā kumu ʻē aʻe, no laila, ke ana ʻana i ke kaomi o ka cylinder engine, hiki iā ʻoe ke ʻike. ka sila o ka hui piston cylinder, inā maikaʻi ke apo piston, valve, cylinder pad seal, a laila pono ka hoʻomaʻemaʻe valve.
