高級火球:劇烈燃燒的火球,接觸目標時發生大爆炸並大范圍的噴射出可以點燃敵人的火焰。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。The timing - and - quantitation precision injection of lpg was realized with high - speed lpg solenoid valve and a set of electronic control system, which was designed by the author and can flexibly control the gas supply system of lpg. based on the analysis of experimental data got by comparing the performances before and after the application of the set of equipment on lr6105q12 diesel engine, the effects of load, speed and replace ratio, etc on the emissions of smoke, hc and co of dual fuel engine were expounded. through optimization, the smoke emission was utmostly reduced and the emissions of hc and co were within the government restriction
為此,本文通過對各個方案進行詳細比較,選擇了電控多點順序噴射的供氣方案;利用高速lpg噴射閥和自己獨立開發出一套電子控制系統對lpg供氣進行靈活地控制,實現了lpg的定時定量噴射,並把這套裝置應用到中國一拖生產的lr6105q12柴油機上,在對改裝前後的發動機進行大量試驗和分析的基礎上,闡明了負荷、轉速、摻燒比等因素對雙燃料發動機的煙度、 hc 、 co等排放的影響情況,並且通過優化,最大限度地降低了發動機的煙度排放,同時使hc 、 co排放限制在國家標準規定的范圍之內。While the speed is very large, the fuel - air mixing behind the airstream is decreased and the span that the fuel flow in the second combustor is reduced, so the combustion efficiency is decreased, h ) if the fuel streams impinge with the airstreams directly at the air - inlet exit, it make against increasing the combustion efficiency, i ) increasing air - to - fuel ratio within proper range can increase the combustion efficiency
增加燃氣噴射速度有利於增強迴流區強度,頭部燃燒溫度上升,但速度太大則會減弱燃氣同空氣在進氣道下游的摻混燃燒,減少燃氣在室內停留時間,燃燒效率降低; 8燃氣射流與空氣流在進氣道出口直接撞擊不利於燃燒效率的提高; 9在適當范圍內增大空燃比能顯著提高燃燒效率。Injection density is often used as a rule of thumb to estimate the difficulty of curing resonant combustion.
時常把噴射密度作為一個經驗法則來估計解決共振燃燒問題時的困難。The last or main injection pulse is set around tdc. when the diesel spray impinging on the combustion wall, the bump around the combustion chamber wall can strip off the wall jet and form a secondary spray in combustion chamber, so the fuel and air can mix well and homogenous
在主噴射時刻,利用燃燒室壁面的bump迅速剝離壁面射流,在空間形成二次射流,二次射流進入燃燒室空間后,再一次與空氣混合,形成相對均勻的稀混合氣。分享友人
