ignition range 中文意思是什麼
ignition range
解釋
點火范圍-
Moreover, it has been pointed out that the hydrogen engine used in ? cylinder injection with high pressure can increase volumetric efficiency and compression ratio, - therefore, the performance indexes in this engine, such as output power, thermal efficiency, range of thickness of mixture with normal operation and nox emission, can be improved, and it is possible for the engine to realize rapid combustion of thin mixture, so abnormal combustion, such as backfire, pre ? ignition, can be controlled effectively
指出了採用內部混合氣形成方式且高壓噴射的氫發動機，有利於提高充氣效率和壓縮比，從而改善發動機的動力性和經濟性；有利於擴展發動機正常工作的濃度范圍；並且有利於實現稀薄混合氣快速燃燒，從而可以有效地抑制早燃、回火及爆燃等異常燃燒和no _ x排放量。試驗指出了發動機的點火正時、噴射正時及噴氫量對發動機的性能、異常燃燒、 no _ x排放量有很大影響。 -
At the conditions with the same fuel injection quantity per cycle and the same engine speed, with the increase of the additive mass fraction in the fuel, the ignition and heat release timings brought forward, the peak of heat release rate increased and the operating range at low engine load was enlarged obviously. however, excessive additives will make the engine be prone to knock, run rudely and shorten the operating range at high engine load
在相同循環噴油量和相同轉速的條件下，隨著添加劑質量分數的增加， hcci著火和燃燒放熱提前，燃燒放熱峰值提高，低負荷工況范圍明顯拓寬，但過高的添加劑質量分數會使得發動機爆震，工作粗暴，導致高負荷工況變窄。 -
All in all, additives are beneficial to improve the ignition of hcci at low engine load and extend the operating range. nevertheless, the knock happens obviously while the range is extending at the high engine speed and load
總之，添加劑有利於改善hcci發動機低負荷著火和拓寬工作范圍，但是在發動機高轉速和高負荷工況下，在工況范圍拓寬的同時， hcci爆震傾向明顯，發動機工作不穩定。 -
Abstract : through comparative tests between the black powder and a mixed powder in the hygroscopicity, combustion performance and output characteristics, their differences in the ignition performance were analysed and the viewpoints were presented on the range of the two kinds of powders
文摘:通過對黑火藥、混合型點火藥在吸濕性、燃燒性能及輸出特性等3方面的對比試驗，分析兩種藥劑作為點火藥使用時點火性能方面的差異，並對其使用范圍提出了看法。
