Ignition sij hawm

Lub tsheb lub engine yog ua los ntawm plaub tshuab, ob mechanisms. Lub ignition system yog yuav tsum tau mus zes cov roj sib tov nyob rau hauv lub engine. Tag nrho cov ntsiab ntawm cov system muab txhim khu kev qha tiv cav tseb, raws li nyob rau hauv lub hauv paus ntsiab lus ntawm qhov kev txiav txim ntawm thooj voos kheej kheej hauv lub tsheb cav. Xav txog cov lus.

Nrog lub cav khiav rau xav paub ntau tshaj combustion ntawm cov roj sib tov yog cig los ntawm muaj nyob ze ntawm lub kawg ntawm lub compression stroke. Nws yog ib qho tseem ceeb yuav tau kho cov ignition tau zoo configured. Txij li thaum lub cav crankshaft thiab cov distributor shafts yog synchronized meej, them nyiaj tiv cav tseb no tshwm sim nyob rau hauv ib tug ncaj qha tsim nyog lub sij hawm. Hais tias yog, tus tso cai ntawm lub crankshaft ntawm ib tug taw tes ntawm sib tov yog Cov nroj cig cuag. Qhov no tshwm sim cyclically nrog alternating mus ua hauj lwm engine. Qhov no yog lub sij hawm ntawm tiv cav tseb.

sib tov ignition system ua hauj lwm heev nti. Tab sis vim yog lub luv nqi ntawm tsau hais, periodic hloov yog tsim nyog tiv cav tseb. Qhov no lub lag luam yog nqa tawm, yog hais tias muaj cov yam ntxwv teeb meem nyob rau hauv engine lub lag luam. Pab tau txoj toxicity ntawm rav cua tsheb gases, tsis ruaj tsis khov lag luam ntawm lub cav - tag nrho cov tej yam kev mob cuam tshuam ntawm cov lag luam ntawm lub system.

Tshuaj tiv cav tseb no yog ua ob thaum lub cav tseem khiav, thiab nyob rau muffled. Yuav kom kho cov muab tshwj xeeb cov cuab yeej thiab cov khoom uas yog tsis ib txwm muaj nyob rau hauv lub chav nres tsheb ntawm ib tug yooj yim txiv neej nyob rau hauv txoj kev. Yog li ntawd, sophisticated yaam puab paub tsav tsheb tswj lub ignition sij hawm thaum lub engine yog khiav. Nws tsis yog nyuaj heev yuav ua li cas. Nws yog ib qho tseem ceeb kom paub yuav ua li cas hnov thiab mloog mus rau lub engine, nws yuav qhia rau koj yuav ua li cas kom raug teem lub ignition sij hawm.

Ceeb toom! Lub voltage nyob rau hauv lub ignition system nce mus txog 12000-24000V. Hais tias yog ib tug ntau. Yog li ntawd, tsis muaj mob ceev heev yuav tsum tau, thiab tsis tau paub tseeb txog lawv txoj kev, tsis txhob kov lub Cheebtsam ntawm lub ignition system, nyob rau hauv particular rau high-voltage txim plug nyob ntawm tej.

Nws yog ib qho tseem ceeb kom nkag siab txog hais tias tus nqi ntawm lub kaum sab xis nyob ntawm ntau yam. Lub combustion tus nqi, ceev thiab lub cav load kho mus rau ib tug tej yam raws li lub kaum sab xis. Lig ignition yog yus muaj los ntawm ib tug loj ua ntej thaum ib tug mob loj tsawv sib hloov ntawm lub cev muaj zog ncej.

Tag nrho lag luam ntawm lub engine, raws li peb tau pom, yog synchronized. Empirically nws pom tias nyob rau hauv tiag tiag lag luam lub cev muaj zog yog suab tsis yooj yim sua kom ua tau lub feem ntau tag combustion ntawm sib tov. Designers los ntawm ib ncig lub ntiaj teb no yog tawm tsam nrog qhov teeb meem no. By thawb lawv ecology. Cias muab, cov roj yog kub tuag ntau kiag li nyob rau hauv lub tog raj kheej, cov uas tsis tshua muaj teeb meem tshuaj mus rau hauv cov cua thiab, yog li ntawd, cov pa kabmob.

Yuav ua kom cov tej yam kev mob lub sib tov nyob rau hauv lub engine yuav tsum teeb ib tug me ntsis ntxov tshaj lub piston yuav txoj kev ua rau tus nqi ntawm lub sab sauv tuag taw tes. Nyob rau hauv no hais txog, cov notion ntawm lub ignition sij hawm. Qhov no kaum sab xis ntawm kev sib hloov ntawm lub crankshaft los ntawm instant ntawm tshwm sim ntawm sparks nyob rau hauv lub txim approximation mus rau lub piston rau nws lub tuag taw tes.

Ntawm cov hoob kawm, tus haum ntawm tus tiv cav tseb nws muaj nws cov drawbacks. Thiab, oddly txaus, yog lub notion ntawm kev haum. Qhov no yog ib qho ntxiv cov txheej txheem kauj ruam, uas yuav tsum tau kev paub, kev txawj ntse thiab kev. Yog hais tias lub hloov yog nqa tawm, nws txhais tau hais tias yog ib tug siab yuav ua rau muaj system tsis ua hauj lwm vim lub xub ntiag ntawm ib tug plurality ntawm cov neeg kho tshuab qhov chaw. Yog li ntawd, hnub no lub tsheb yog nce nruab nrog ntau txhim khu kev qha txij nkawm-dawb system uas eliminates no drawback.

Thiab lub xeem point: yog hais tias peb xav hais tias ib yam ntawm lub tshuab uas yog lub luag hauj lwm rau lub ignition sij hawm, tsis ua hauj lwm, kev lom zem ntau poob lub tsheb puab ntawm dispersal, raws li zoo raws li nce tau ntawm roj av.
