duration of combustion 中文意思是什麼

duration of combustion 解釋
燃燒持續時間
  • duration : n. 1. 持久，持續。2. 持續時間，存在時間；期間。adj. -al
  • of : OF ＝Old French 古法語。
  • combustion : n. 1. 燃燒，發火，點火。2. （有機體內營養料的）氧化。3. 騷動。
  1. The investigation has declared that the fuel injection with bq fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule - air mixture to increase during ignition delay period, the pre - mixed combustion to become acutely, and finally result in increased power levels of noise

    研究表明，裝配bq噴油泵，噴油系統的噴油壓力較高，供油速率較大和供油持續時間縮短，使得滯燃期的噴油量增加，滯燃期內形成的可燃混合較多，預混燃燒劇烈，導致整機噪聲聲功率級增加。
  2. The advantages of hcci are numerous comparing with the traditional engine. relative to si gasoline engines, hcci engines are more efficient, because they have no elimination of throttling losses, use the high compression ratios and have shorter combustion duration. relative to cidi engines, hcci engines have extraordinarily lower emissions of pm and nox and can offer more power as high as cidi engines with the dilute homogeneous air and fuel mixture

    與傳統的發動機相比均質壓燃（ hcci ）具有很多優勢:與火花點火汽油機相比， hcci發動機由於沒有節流損失，壓縮比較高，燃燒持續期短，其效率更高;與直噴柴油機相比， hcci發動機的碳煙和氮氧化物排放非常低，並且稀薄空燃混合氣可以產生與柴油機一樣高的功率。
  3. The results of study show that the transmitting speed of flame is slower and the combustion duration is longer than gasoline. the combustion status of lpg is improved, but the problem of long combustion duration also exists when speed and load are increased. it is useful to adjust ignition timing, but nox emission increase

    通過研究認識到： lpg燃燒時火焰傳播速度比汽油慢，燃燒持續期比汽油長；隨著轉速和負荷的增大， lpg燃燒狀況得到改善，但仍出現后燃期長，熱量利用不充分等問題；點火提前角的調整有利於lpg的燃燒，但使nox排放升高。
  4. Under this background, we successfully developed an engine fuelled with coal - bed gas and ignited by spark plug. the measurements for the prototype engine were thoroughly made, including the cylinder pressure, the rate of heat release, combustion duration, ignition delays, spark ignition angle, and the fluctuation of the cylinder maximum pressure

    在此背景下，本文對經由s195柴油機改裝得到的燃用變組分煤層氣發動機進行了全面的測試和分析，包括缸內示功圖、燃燒放熱率、主燃期、點火提前角、火焰發展期以及最大壓力循環波動等。
  5. Fuel efficiency and power output and emission of an internal combustion engine can be significantly improved by optimizing intake and exhaust valve timing and duration and lift as speed changes during operation

    改變發動機氣門的開啟相位、持續時間和升程是改善發動機性能，提高熱效率和減少有害排放的一種重要方法。
