oxygen fuel ratio 中文意思是什麼
oxygen fuel ratio
解釋
氧-燃料比-
In recent years at iron - making plant of pangang, the coke ratio of pig iron has reduced evidently by insisting on “ burden preparation ” course, improving quality of sinter, raising wind temperature, increasing rich oxygen quantity and injecting abundant pulverized coal into bf. the solid fuel consumption of sinter has been decreased greatly through insisting on using high - quality calces, practising high feed sintering, actualizing many techniques in solving key problems. at the same time, the energy source base management has been strengthened, and energy - saving work has made great progress, profits generated by energy - saving have exceeded a hundred million yuan
近年煉鐵廠通過堅持「精料」方針，改善燒結礦質量，提高風溫，增大富氧，實施大噴煤，使入爐焦比有明顯下降；燒結堅持用好生石灰，推行厚料層燒結，實施多項技術攻關，固體燃耗大幅度下降；同時加強能源基礎管理，節能工作取得長足進步，節能創效益1億元以上。 -
The air - fuel ratio closed loop control adjusts the air - fuel ratio near the theoretical value by controlling the supplementary air of supplementary valve based on the signals of oxygen sensor, running speed and water temperature and which is necessary condition for three - way catalyst converter to work more efficiently
空燃比閉環控制是根據氧傳感器、轉速和水溫信號，控制化油器后補氣閥補氣將空燃比控制在理論值附近，為三元催化轉換器高效工作準備必要條件，使其最大限度降低尾氣排放。 -
The simulations results show that the average combustion temperature is much lower in fuel - rich state and little higher in oxygen - rich state near the best o / f ratio. by extending the post - chamber length the oxidizing gas and the fuel pyrolytic gas can burn completely and the average combustion temperature can be prominently increased. the fuel - rich recirculation zone close to the head of combustion chamber is very important for the combustion
計算結果分析表明：發動機在富燃狀態下平均燃燒溫度偏低，在接近理想配比的富氧狀態下平均燃燒溫度有所提高；加長補燃室可以大幅度提高發動機的平均燃燒溫度，並促進氧化劑氣體和熱解氣體的充分燃燒；燃燒室頭部的富燃迴流區對發動機的燃燒非常重要，去掉燃燒室頭部突擴段后，氧化劑氣體和燃料熱解氣體不能充分燃燒，發動機的平均燃燒溫度大幅下降。 -
Exhaust gas oxygen sensor ( ego ) which is installed in the exhaust pipe of the engine is a significant component in the electronic fuel injection. it has the ability to probe the concentration of oxygen in the exhaust pipe, and can transfer concentration signal to voltage signal which is passed to electronic control unit ( ecu ). in this way the air - fuel ratio can be controlled to the strait range of stoichiometrical point and the three - way catalytic converter consequently can work better
車用氧傳感器是電噴系統的關鍵部件，安裝在發動機的排氣管上，能夠探測排氣管中的氧氣的濃度，然後將濃度信號轉變成電壓信號並傳送給電控單元ecu ，從而把空燃比控制在理論空燃比附近，配合三元催化反應器進行后處理凈化。 -
Moreover, oxygen detector is suggested to the system structure, which can control the second wind pump to control the ratio of wind and fuel
此外，在原有系統結構的基礎上，增加了煙道含氧量檢測，根據煙道含氧量來控制二次風機以達到最佳空燃比。
