He aha ia? Nā kumu a me nā hopena
Piʻi pinepine nā pilikia ʻenekini ma muli o ka haki ʻana o ka nui o ka hui ʻana o ka wahie-ea.
ʻO ka mea maikaʻi loa, pono e komo i hoʻokahi dosis o TVS:
- 14,7 hapa o ka ea;
- 1 ʻāpana ʻaila.
ʻO ka ʻōlelo maʻalahi, pono e hāʻule ka 1 lita o ka ea ma 14,7 lita o ka ʻaila. ʻO ka carburetor a i ʻole ka ʻōnaehana injection injection ke kuleana no ka hoʻonohonoho pono ʻana o nā hui wahie. Ma nā kūlana like ʻole, hiki i ka Electronic Control Unit ke kuleana no ka hoʻomākaukau ʻana i ka hui ʻana i nā ʻāpana like ʻole, no ka laʻana, inā pono e hoʻonui i ka traction a i ʻole, e hoʻololi i kahi ʻano hoʻohana ʻoi aku ka waiwai.
Inā hōʻino ʻia nā ʻāpana ma muli o nā hewa like ʻole o ka ʻōnaehana injection, a laila hiki iā ʻoe ke loaʻa:
- nā hui wahie maikaʻi ʻole - ʻoi aku ka nui o ka ea ma mua o ka waiwai i hoʻonohonoho ʻia;
- TVS waiwai - ʻoi aku ka ʻaila ma mua o ka pono.
Inā hoʻolako ʻia kāu kaʻa me kahi probe lambda, a mākou i kamaʻilio ai ma Vodi.su, a laila e hāʻawi koke ka kamepiula ma luna o ka papa i nā hewa ma lalo o kēia mau code:
- P0171 - nā hui wahie maikaʻi ʻole;
- P0172 - ka hui ʻana i ka ea-wahie waiwai.
E pili koke ana kēia mau mea i ka hana o ka ʻenekini.
ʻO nā hōʻailona nui o kahi hui lean
Nā pilikia nui:
- overheating o ka ʻenekini;
- like 'ole o ka manawa valve;
- hoemi nui i ka traction.
Hiki iā ʻoe ke hoʻoholo i ka hui ʻana o ka lean e nā hōʻailona hiʻohiʻona ma nā plug sparks, ua kākau pū mākou e pili ana i kēia ma Vodi.su. No laila, ʻo ka ʻulaʻula hina a keʻokeʻo paha e hōʻike ana i ka pau ʻana o nā hui wahie. I ka hala ʻana o ka manawa, hiki ke hoʻoheheʻe ʻia nā electrodes plug ma muli o nā wela kiʻekiʻe mau.
Eia naʻe, ʻoi aku ka pilikia nui o ka wela o ka ʻenekini a ma muli o ka pau ʻana o nā pistons a me nā valves. Hoʻopau ka ʻenekini no ka mea ʻoi aku ka nui o ka gasoline lean me ka oxygen kiʻekiʻe e pono ai ka wela kiʻekiʻe e puhi. Eia kekahi, ʻaʻole pau ka ʻaila a pau, a me nā kinoea hoʻopau, komo i loko o ka exhaust manifold a ʻoi aku i loko o ka ʻōnaehana exhaust.
ʻO nā pahū, nā pops, nā puhi i loko o ka resonator - ʻo ia nā hōʻailona āpau o kahi hui lean.
He mea pono e hoʻomaopopo ʻoiai ke kali nei nā pilikia koʻikoʻi i ka mea nona ke kaʻa, e hana mau ana ka ʻenekini. Inā hoʻololi ka nui o ka oxygen i ka ʻaila i 30 a hoʻokahi, ʻaʻole hiki ke hoʻomaka ke ʻenekini. A i ʻole e kū ʻo ia ma kāna iho.
ʻO ka hui lean ma HBO
Hiki ke ʻano like i nā hihia kahi i hoʻokomo ʻia ai kahi hoʻokomo kinoea-cylinder ma ke kaʻa. ʻO ka nui o ke kinoea (propane, butane, methane) i ka ea he 16.5 hapa o ka ea i ke kinoea.
ʻO nā hopena o ka liʻiliʻi o ke kinoea e komo ana i loko o ke keʻena puhi ahi ma mua o ka mea e pono ai, ua like ia me nā mīkini ʻaila:
- overheat;
- ka nalo ʻana o ka traction, ʻoiai inā ʻoe e neʻe ana i lalo;
- ka pahū ʻana i ka ʻōnaehana hoʻopau ma muli o ka pau ʻole ʻana o ka wahie kinoea.
E hōʻike pū ana ka kamepiula ma luna o ka papa i kahi helu hewa P0171. Hiki iā ʻoe ke hoʻopau i ka hana ʻino ma ka hoʻonohonoho hou ʻana i ka hoʻonohonoho kinoea a i ʻole ka hoʻololi ʻana i nā hoʻonohonoho o ka palapala ʻāina mana.
Pono ʻoe e nānā i ka ʻōnaehana injection. ʻO kekahi o nā kumu maʻamau o ke komo ʻana o ka hui ʻana o ka ea-wahie lean (petrol a LPG) i loko o ka ʻenekini nā nozzles injector paʻa. I kēia hihia, ʻo kekahi o nā hopena hiki ke hoʻomaʻemaʻe iā lākou.
Ke hoʻouka nei…
