Exhaust System
Exhaust system from the combustion chamber vent connected via exhaust manifold, exhaust, and to the middle, is the whole paragraph tailpipe emissions process, automobile exhaust system mainly a function, one is the hot flue gas fuel after burning lead to the car or to avoid car side eduction, influencing interior occupant; it is using silencers will emissions in high temperature and pressure in the process of noise dropped to the allowable limit.
Emissions in the process of exhaust manifold is first encounter. Exhaust manifold design on the most important is to avoid between each cylinder of the exhaust gas interference, make each other as much as possible from the exhaust pipe completely, the role of the middle itself will come from relatively simple, as long as the exhaust gas exhaust manifold guide to exhaust the tail pipe, some exhaust system in the middle to install a more expansive room to reduce exhaust pressure; Because of the high temperature and high pressure inside engine exhaust manifold into the waste gas pressure remained high, at this time when for exposure to exhaust manifold wall and will produce shock, it appears the frequency of thousands of times per minute, quite high frequency annoying noise, so need good add processing.
When the exhaust after exhaust manifold later, its shock waves from Seattle already reduced to even the low dissipation traversed the shock, but at the moment the noise is still large, light the midway to reduce its after piping in the middle, so powerful and paragraph place should add turgor zhang chamber and muffler to offset its power, some vent-pipe a muffler design only paragraph, some can in a more expansive room in the middle, muffler and expansion chamber, the difference between similar muffler internal have multilayer clapboard or porous direct pipeline to absorb sound velocity, and spread reduce expansion Chambers simply a hollow large containers, its purpose is pure land to reduce pressure to exhaust expansion, so one more expansive room design can make noise is reduced many.

捷達(dá)汽車排氣裝置實(shí)驗(yàn)臺(tái)使用說明及注意事項(xiàng)
在使用本實(shí)驗(yàn)臺(tái)前，請(qǐng)仔細(xì)閱讀實(shí)驗(yàn)臺(tái)使用說明及注意事項(xiàng)，按照規(guī)范操作，防止損壞實(shí)驗(yàn)臺(tái)或?qū)?shí)驗(yàn)人員人身傷害。
一、實(shí)驗(yàn)臺(tái)使用說明
1.電源連接
將電瓶正負(fù)極線分別連接，先負(fù)后正。
將開關(guān)鑰匙打到ON位置，實(shí)驗(yàn)臺(tái)啟動(dòng)。
2.點(diǎn)火開關(guān)
將開關(guān)鑰匙打到ON位置，實(shí)驗(yàn)臺(tái)啟動(dòng)。
開關(guān)旋至OFF位置時(shí)，實(shí)驗(yàn)臺(tái)停轉(zhuǎn)。
3.消聲器更換
用于更換不同車型的消聲器來進(jìn)行測(cè)試時(shí)，要注意旋轉(zhuǎn)開關(guān)到OFF位置，使實(shí)驗(yàn)臺(tái)轉(zhuǎn)后，在更換不同型號(hào)的消聲器。
二、注意事項(xiàng)
1.實(shí)驗(yàn)臺(tái)使用的電源有12V蓄電池直流電源，請(qǐng)勿使用不同規(guī)格電源，以防止損壞元器件。
2.因?yàn)樵撛O(shè)備采用12V電源，故使用該設(shè)備前為了防止漏電、靜電和損壞電器元件，設(shè)備本身一定要接地。設(shè)備用完后請(qǐng)及時(shí)斷電。
3.設(shè)備運(yùn)轉(zhuǎn)時(shí)，請(qǐng)與發(fā)動(dòng)機(jī)旋轉(zhuǎn)部件保持足夠的安全距離，以防對(duì)人體造成傷害。
4.進(jìn)行排氣管上氧傳感器安裝時(shí)，請(qǐng)勿破壞別的線路的連接。
5.使用結(jié)束后，請(qǐng)關(guān)閉點(diǎn)火開關(guān)，斷開蓄電池連線。
6.其他相關(guān)事項(xiàng)請(qǐng)聽從專業(yè)人員指導(dǎo)。
