LPG (ʻaila kā aila hoʻoheheʻe ʻia)
ʻO ka LPG kahi hui liquefied o propane, butane a me nā mea hoʻohui ʻē aʻe, i hana ʻia i ka wā o ka hana ʻana i nā meaʻai aila. I ka mokuʻāina mua, ʻaʻohe ona kala, ʻono a me ka ʻala, no laila, ua hoʻohui ʻia kahi mea ʻala i ka hui ʻana - he mea ʻala (kahi mea me kahi ʻala ʻano). ʻAʻole ʻawaʻawa ʻo LPG, akā ʻaʻole komo i ka ea a loaʻa ka hopena ʻona. Ma ke kinoea, ʻoi aku ke kaumaha ma mua o ka ea, a ma ke ʻano wai, ʻoi aku ka māmā ma mua o ka wai. No laila, ʻaʻole pono e waiho ʻia nā kaʻa LPG i loko o nā hale kaʻa ma lalo o ka honua, no ka mea, inā he leak, e noho mau ka LPG ma nā wahi haʻahaʻa a hoʻoneʻe i ka ea hanu.
Hana ʻia ʻo LPG i ka wā o ka hana ʻana o nā meaʻai aila aila. Hoʻopili ʻia ia e ka hōʻoluʻolu a i ʻole ke kaomi ʻana e hōʻemi i kāna manawa 260 mau manawa. Hoʻohana ʻia ka LPG ma ke ʻano he koho ʻoi aku ka makepono i ka petrolina ma muli o ke ʻano like o kāna mau waiwai. He wahie maikaʻi loa ia me ka helu helu octane ma kahi o 101-111. I ko mākou kūlana, ka mea i kapa ʻia ʻo ka hoʻoilo LPG hoʻoilo (60% P a me 40% B) a me ka hui LPG kauwela (40% P a me 60% B), ʻo ia hoʻi. hoʻololi i nā lakio like o propane a me butane.

No ka hōʻike kikoʻī kikoʻī (waiwai calorific, waiwai calorific, a pēlā aku), ua wehewehe ʻia ka "Theeoretical Equivalence Coefficient" no kahi nui o ka wahie e loaʻa ana kekahi ʻano o ka ikehu e like me ka waiwai calorific o ka ʻailaolina.

E lawe mākou i kahi kaʻa me kahi mile mile kinoea ma kahi o 7 liters. A laila (e noʻonoʻo ana i ka hoʻohui ʻana o ka hui kauwela a me ka coefficient kaulike, loaʻa iā mākou ke ʻano:
(ka hoʻohana ʻana o ka penehika * (40 pākēneka propane me ka like o 1,27 + 60 pākēneka butana me ka like o 1,11)) = LPG ʻai
7 * (0,4 * 1,27 + 0,6 * 1,11) = 7 * 1,174 = 8,218 l / 100 km v lete
7 * (0,6 * 1,27 + 0,4 * 1,11) = 7 * 1,206 = 8,442 l / 100 km i ka hoʻoilo
Pēlā, ka ʻokoʻa o nā kūlana aniau like 0,224/ 100 km. I kēia manawa, he mau helu theoretical kēia, akā wehewehe lākou i ka ʻoiaʻiʻo e ulu wale ka ʻai ma muli o ka hoʻoilo. ʻOiaʻiʻo, kuleana lākou no ka hoʻonui hou ʻana i ka ʻai - nā kaila hoʻoilo, hoʻomaka ka hoʻoilo, ʻoi aku ka mālamalama, ka hau ma ke alanui, ʻoi aku ka liʻiliʻi o ka wāwae, etc.
