中文拼音 [bàozhènjì]
爆震劑
英文
knock producer-
Then using kerosene as fuel, oxygen and compressed air as oxidizers, proof - of - principle experiments of pdre were successfully conducted the results show that the measured detonation wave pressures are close to theoretical values it also indicate that using kerosene as the fuel of pdre is feasible
採用航空煤油為燃料，氧氣和壓縮空氣為氧化劑，分別進行了兩相脈沖爆震火箭發動機原理性試驗，所測得的爆震波壓力接近充分發展的理想爆震波壓力，說明採用煤油作為脈沖爆震火箭發動機的燃料是可行的。In order to investigate the influence of characteristics parameters on detonation wave in a two - phase pulse detonation engine model. the peak detonation pressures and average velocities of two - phase pulsed detonation wave produced by pde model using gasoline as fuel and air as oxidizer under various ignition frequencies and various mixture ratios are measured systematically, and the relations influencing them are analyzed
為了探索氣-液兩相脈沖爆震發動機模型內特徵參數對產生爆震波的影響規律，系統地測試了以汽油為燃料、以空氣為氧化劑的氣-液兩相脈沖爆震發動機模型在不同點火頻率及不同余氣系數下爆震波的峰值壓力以及平均爆震波速，並對其變化進行了分析。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。分享友人
