LPG (gaaska batroolka dareeraha ah)
LPG waa isku dhafka dareeraha ah ee propane, butane iyo waxyaabo kale oo lagu daro, kaas oo la sameeyo inta lagu jiro habaynta kaydka batroolka. Xaaladda bilawga ah, ma laha midab, dhadhan iyo ur, sidaas darteed, wakiilka ur ayaa lagu daraa isku dhafka - ur (walax leh ur dabeecad leh). LPG ma aha sun, laakiin ma gasho hawada waxayna leedahay saameyn sun ah oo dhexdhexaad ah. Xaaladda gaaska, way ka culus tahay hawada, iyo xaaladda dareeraha, way ka fudud tahay biyaha. Sidaa darteed, baabuurta LPG waa in aan looga tagin garaashyada dhulka hoostiisa ah, haddii ay dhacdo in ay dhacdo, LPG waxay had iyo jeer degi doontaa meelaha ugu hooseeya waxayna barakicisaa hawo neefsasho leh.
LPG waxaa la soo saaraa inta lagu guda jiro habaynta kaydadka shidaalka. Waxaa lagu cabaa qaboojinta ama cadaadinta si loo yareeyo muggeeda 260 jeer. LPG waxaa loo isticmaalaa beddel ka raqiisan baatroolka maadaama hantidiisu aad isugu eg tahay. Waa shidaal aad u wanaagsan oo lagu qiimeeyo octane qiyaastii 101-111. Xaaladeena, waxa loogu yeero isku-darka jiilaalka LPG (60% P iyo 40% B) iyo isku-darka LPG xagaaga (40% P iyo 60% B), i.e. Isbeddelka saamiyada wadaagga ah ee propane iyo butane.

Qeexitaan sax ah (qiimaynta calool -mareenka, qiimaynta kalooriga, iwm.), “Isku -dheelitirnaanta Isku -Darka Teoretical” waxaa lagu qeexaa mugga shidaal oo ay ku jirto xoogaa tamar ah oo u dhiganta qiimaha kalooriga ee batroolka. Kadibna "saamiga u dhiganta saamiga dhabta ah" ee u dhexeeya isticmaalka mishiinka ayaa la go'aamiyaa, kaas oo aan isbarbar dhigi karno sida ugu fiican ee suurtogalka ah.
| Shidaalka | Isbarbar dhigga aragti ahaaneed | Saamiga sinnaanta |
|---|---|---|
| Shidaalka | 1,00 | 1,00 |
| Propane | 1,30 | 1,27 |
| Bhutan | 1,22 | 1,11 |
Aynu qaadanno baabuur celcelis ahaan masaafada gaaska oo qiyaastii ah 7 litir. Markaa (iyadoo la tixgelinayo isku -darka isku -darka xagaaga iyo isku -dheelitirka u dhigma, waxaan helnaa qaaciddada:
(isticmaalka gaaska *
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 v jiilaalka
Markaa, farqiga u dhexeeya xaaladaha cimilada ee isku midka ah ayaa noqon doona 0,224/ 100 km. Ilaa hadda, kuwani waa dhammaan tirooyinka aragtida, laakiin waxay sharxayaan xaqiiqda ah in isticmaalka kori doono oo kaliya sababtoo ah qaboojinta. Dabcan, waxay sidoo kale mas'uul ka yihiin kororka dheeraadka ah ee isticmaalka - taayirada jiilaalka, jiilaalka bilawga, iftiin badan, barafka wadada, laga yaabee xitaa dareenka lugta yar, iwm.
