Therefore, through use depressor, may 120MPa pression natural gas pressure drop to enters the mixer, in order to enters the cylinder with the air mix, because in the highpressure bottle CNG gas pressure changes, must maintain the stable airfuel ratio control, also requests regardless of how the bottle internal pressure does change, the reduced pressure regulator also should guarantee enters the mixer basically the fuel gas pressure constant, by this realization quite stable fuel gas and air mixture ratio control. Thus realization reduced pressure and constant voltage function. This graduation project in original reduced pressure product foundation, have carried on the revision to its structural configuration and the shape, and to input in the engine process the natural gas pressure change value to carry on the precise design, mainly is to the level pressure relief valve slit reduced pressure and two level of pressure relief valve slit reduced pressure, as well as three levels of pressure relief valves carry on the reduced pressure using the vacuum degree to carry on the putation, enables its to satisfy the reduced pressure to the anticipated request. Moreover to each mainly has been carried on the load spare part the intensity examination, causes the choice the material to satisfy the intensity request. Estimated this time designs the depressor has the structure simply, the layman is artistic, precision high characteristic, may enhance the similar product the quality, May satisfy the user munity the demand.Key words: Natural gas automobile。 depressor。 pressure relief valve目錄摘要?ABSTRACTП緒論11111 設(shè)計(jì)任務(wù)書333333344472 設(shè)計(jì)方案的研究與選擇99999 設(shè)計(jì)方案的選擇103 總體方案設(shè)計(jì)1111111彈簧與閥口的設(shè)計(jì)11191杠桿、上檔板的設(shè)計(jì)1919222杠桿、上擋板、閥口的設(shè)計(jì)2222 三級(jí)減壓閥膜片的設(shè)計(jì)與校核25262626282先導(dǎo)閥、彈簧的設(shè)計(jì)293031324 天然氣汽車減壓裝置的使用說明353檢查與調(diào)整353檢查、更換3調(diào)整365 總結(jié)38謝辭39參考文獻(xiàn)40汽車畢業(yè)論文:Santana2000轎車制動(dòng)系統(tǒng)設(shè)計(jì)摘要國(guó)內(nèi)汽車市場(chǎng)迅速發(fā)展，而轎車是汽車發(fā)展的方向。然而隨著汽車保有量的增加，帶來的安全問題也越來越引起人們的注意，而制動(dòng)系統(tǒng)則是汽車主動(dòng)安全的重要系統(tǒng)之一。因此，如何開發(fā)出高性能的制動(dòng)系統(tǒng)，為安全行駛提供保障是我們要解決的主要問題。另外，隨著汽車市場(chǎng)競(jìng)爭(zhēng)的加劇，如何縮短產(chǎn)品開發(fā)周期、提高設(shè)計(jì)效率，降低成本等，提高產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力，已經(jīng)成為企業(yè)成功的關(guān)鍵。本說明書主要介紹了santana2000轎車制動(dòng)系統(tǒng)的設(shè)計(jì)。首先介紹了汽車制動(dòng)系統(tǒng)的發(fā)展、結(jié)構(gòu)、分類，并通過對(duì)鼓式制動(dòng)器和盤式制動(dòng)器的結(jié)構(gòu)及優(yōu)缺點(diǎn)進(jìn)行分析。最終確定方案采用液壓
