Gas khoom 4 tiam: qhov zoo thiab qhov tsis zoo

Kuj nyuam qhuav, roj khoom 4 tiam tau kis. Nws yog ntau npaum li cas zoo tshaj yav dhau los system, raws li nws tso cai rau ua kev tswj ntawm engine ua hauj lwm, ntawm sensor readings. Nws yuav tsum tau muab sau tseg hais tias xws li cov khoom yog siv nyob rau hauv lub tsheb nrog txhaj tshuaj roj txhaj system. Firstly, muaj ib tug xav rau calibration, uas yog tsim los ntawm cov ntaub ntawv tau los ntawm kev petrol injectors. Secondly, qhov chaw ua hauj lwm muab kev koom tes ib tug xov tooj ntawm sensors - ntws nqi, position lub throttle, khob, ceev, thiab lwm tus neeg.

Cov kev pab cuam ntawm LPG khoom

Nws yuav tsum tau hais txog yus nta HBO 4 tiam, uas tuab lub zoo qualities nyob rau hauv kev sib piv nrog yav dhau los systems:

• roj (gas) los ntawm kev siv ntawm yam tsawg kawg nkaus microcontroller lag luam tswj system khoom;
• engine loses tsawg npaum li cas hwj chim - tsis muaj ntau tshaj li 1-2% thaum piv rau ua ntej lawm systems, ces lawv tso cai rau ib tug txo nyob rau hauv hwj chim ntawm lub hwj chim tsev los mus txog rau 30%;
• Faib nruab nrog HBO 4 tiam, raws li Euro-2 toxicity, Euro-3 thiab Euro-4;
• thaum lub cav ua hauj lwm nyob rau hauv roj roj tsis muaj popping cov yam ntxwv ntawm ua ntej lawm systems;
• hluav taws xob tsev system HBO 4 tiam siab tshaj nrog rau-board self-mob EOBD network, tsis tau siv ntxiv emulators;
• thaum lub sij hawm lub installation nws yog yooj yim sua kom yuam kev, ua hauj lwm yog nqa tawm haum tsuas vim lub fact tias tag nrho cov hlau sib txuas yog tua nyob rau hauv daim ntawv ntawm ib tug ntau yam ntawm connectors, lawv yuav tsis yuav tsis meej pem, li ntawd, txoj kev pheej hmoo ntawm tsis yog thaiv yog cais;
• tus nqi ntawm cov khoom nrog microprocessor tswj system yog yuav luag sib npaug rau tus nqi ntawm obsolete khoom nrog rau cov xws li nrog lambda sojntsuam.

disadvantages HBO

Tsis muaj tus drawbacks tsis tsav system. Piv rau roj av, nkev, muaj ib tug disadvantage, uas yog lub loj - calorific nqi yog me npaum li cas. Vim li no, lub cav fais fab dauv pab - nyob rau hauv thawj tiam thiab 30% nyob rau hauv lub 4 thiab 5 - 2-3%, tab sis, nyob rau hauv lub hom roj siv, lub hwj chim tsis yuav ncav cuag ib nqi siab tshaj plaws ntawm 5%. Gas khoom 4 tiam (tshiab cov khoom siv nqi - txog 20 txhiab rubles) yuav muab ntsia tau rau nyob rau ntawm tej tsheb, lub hwj chim tsis yog nyoog.

Rau ib txwm lag luam ntawm lub system, nyob rau hauv thiaj li yuav txo lub hwj chim tsis yog teem me ntsis ua ntej lub ignition (kwv yees li tsib degrees). Cov xav li cas xwb ntawm qhov kev txiav txim yog questionable. Firstly, raws li yog tso cai ua, Yog hais tias lub tsheb yog khiav ntawm petrol nrog ib tug octane ntsuam xyuas ntawm ntau tshaj 95. Qhov no yog ua nyob rau hauv thiaj li tsis mus nqa tawm kev hloov ntawm lub ignition thaum switching fuels. Tab sis nyob rau hauv cov neeg mob, nws yog tej zaum yuav siv octane-corrector. Txawm li cas los, tsis yog txhua lub tsheb octane-corrector thiab roj khoom 4 tiam, xyuas uas yuav luag tag nrho cov zoo, yuav tau ua num nquag.

Ob, kev tshawb fawb qhia tau hais tias thaum uas pub mis natural gas yuav tsum tau ib tug tom qab tiv cav tseb thaum muaj kev kub engine speeds. Piv nrog roj, ces, yog tias muaj, lub ignition yuav tsum tau ntsia tom qab. Ntawm cov "me" shortcomings yuav qhia tau ib tug ntau - ib tug loj tank nyob rau hauv lub cev (raws li ib tug txoj cai, qhov no yog qhov chaw uas nws yog tsim los). Tsis tshua muaj neeg yooj yim yog tias koj siv lub tsheb rau lub tsheb thauj mus los ntawm cov khoom. Tab sis muaj tso tsheb hlau luam ntawm toroidal zoo, rov qab ua dua qhov nkhaus ntawm lub spare log.

Lub ntsiab units ntawm HBO 4 Tiam

Yuav kom cia compressed roj kheej kheej siv. Yuav kom nws tau raws li tej yam uas yuav tsum tau - ceev ceev, kev cia siab thiab durability. Yuav kom siv cov roj tank rau lub tsheb daim ntawv tso cai yuav tsum tau. Nws muaj peev xwm muab tawm los ntawm cov kws tshwj xeeb uas yog ntawv pov thawj mus nqa tawm kev ua no. Txij li thaum cov roj txhaj tshuaj yuav siv sij hawm qhov chaw nyob rau ib tug siab dua hais tias nyob rau hauv lub tog raj kheej, nws yog tsim nyog los txo nws. Rau lub hom phiaj no, siv ib tug reducer. Lub methane sib lawv muaj ob tug siab yuav txo tau nyob ntev, thiab hluav taws roj zeb-butane yog txaus suab. Yog vim li cas - nyob rau hauv thawj cov ntaub ntawv, lub siab nyob rau hauv lub tog raj kheej yuav ncav cuag qhov tseem ceeb mus txog 200 bar, nyob rau hauv lub thib ob - 16.

Gas nozzles yuav tsum rau hno roj rau hauv lub combustion chamber. Lawv muaj kev cob cog nrog ib tug reducer-tshuab ntxhua. rau tag nrho cov system yog tshuaj los ntawm ib tug hluav taws xob filling - ib lub computer uas sau los ntawm cov microprocessor. Nws yog pw firmware uas muab lub lag luam raws li ib tug pre-xav-tawm algorithm. Gas khoom 4 tiam muaj ib tug kom zoo dua li ua ntej lawm - roj xaiv yuav ua li cas txiav, tsis muaj tus tsav tsheb. Rau lub hom phiaj no xwb, thiab yog yuav tsum tau mus nrhiav kom tau hais tias tus tes hloov qhov roj-roj mus rau tus thawj txoj hauj lwm.

Yuav ua li cas puas muaj tus computer?

Nyob rau hauv lub lag luam, nws yog nyeem tag nrho cov ntaub ntawv uas tuaj txog ntawm lub sensors. Nyob rau hauv kev, lub teeb liab tsom xam yog ua, extending los ntawm lub lambda sojntsuam - ib tug mounted rau katkollektora thib ob - tom qab. Ib tug tseem ceeb thiab lwm yam yog kev txhim kho kom. Tag nrho tsis yog nyeem los ntawm cov sensors yog pub rau ib tug microprocessor cov tswv yim. Tiam sis ntawm no yog ib tug me me teeb meem - lub teeb liab lub zog nyob rau hauv ib co cov txawj nyeem ntawv siab, thaum lwm tus neeg - heev me me. Kev txuam sensors thiab cov tswv yim ports ntawm microcontroller yog siv txuam kiag li lawm.

Piv txwv li, kub sensors, ua rau lub hauv paus ntawm thermistors, outputs 12 Volt. Mus sum txog lub microcontroller, nws yuav tsum tau tsis muaj ntau tshaj 5 volts. Rau lub hom phiaj no, voltage dividers, uas yog raws li nyob rau hauv resistors thiab diodes. Tu siab, tsis ntev los no roj khoom 4 tiam, tus nqi ntawm uas muaj ntau zog vim rau qhov kev nce rau ntawm lub duas thiab cov euro muaj ntau tus nqi nyob rau hauv ntau lub respects vim lub high nqi ntawm cov hluav taws xob kev tswj chav tsev. Yog hais tias nws yog ib tug ob peb xyoos dhau los nws muaj nqis 5-7 txhiab rubles, tam sim no tsawg tshaj li 10 txhiab yog tsis zoo li mus nrhiav tau. Peb yuav tau tham txog lub tshiab kiag li lawm. Siv cov sensors uas muaj tsawg lub teeb liab theem nqa tawm los ntawm theem nyob rau hauv kev ua hauj lwm amplifiers, bipolar los yog teb cov nyhuv transistor.

Yuav summed li - ib tug ntau ntawm cov nyiaj los pab cawm roj khoom 4 tiam. Txhim kho nws yog yooj yim, cov kev pab cuam qhov chaw nres tsheb nws yuav siv sij hawm ib nrab ib hnub twg, thiab tus nqi - nyob ib ncig ntawm 2500-3500 rubles. Tab sis nws yog tsim nyog los saib yuav ua li cas koom koj siv koj lub tsheb. Yog hais tias lub roj rau hauv lub xyoo yog tsawg tshaj li 30 txhiab kilometers, lub HBO them tawm yuav ntev heev. Yog hais tias siab nqi, rau ib lub xyoo, thiab tej zaum tsawg dua, kev txaus cai lub installation ntawm cov khoom los ntawm cov nyiaj txiag sab.
