短燃時發動機 的英文怎麼說
中文拼音 [duǎnránshífādòngjī]
短燃時發動機
英文
short-burning engine-
So in order to meet the more strict emission regulations, it is necessary to quicken the rise of temperature and shorten the light - off time of the monolith
因此為滿足更嚴格的排放法規，應有針對性地採取措施加快催化轉化器載體的溫升，縮短起燃時間，有效降低發動機的排放。For instance, no matter what kind of engine they invent, a flying car will always burn more fuel than a regular car, especially on short trips ( you burn a bunch of gas trying to overcome that gravity thing on takeoff )
比如，無論他們發明什麼樣的發動機，一輛飛車總會比普通汽車燒更多的燃料，短途的時候尤其明顯（在起飛時，你必須燒掉很多汽油來克服重力） 。There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields
進行雙模態沖壓發動機地面試驗研究時，必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫（或總焓）以及來流氣體的流動速度；同時由於燃料在燃燒室內駐留的時間很短，一般為毫秒量級，從而使流場物理量的測定顯得非常困難。It is discovered that the fluctuating increment of the instantaneous angular acceleration curve of crankshaft ( ay method ) put forward in this paper can be used to diagnose the power and compression condition of multi - cylinder engine in the state of shorter, more rigid crankshaft and lighter torsional vibration and in the rapidly diagnosed situation, and the ay method is better than the fluctuating increment of the instantaneous rotation speed curve of crankshaft ( n method ) which is used widely now
結果發現，在內燃機曲軸較短、剛性較大、扭振較小、對診斷速度要求很快的場合，用本文提出的曲軸瞬時角加速度波動增量j法能較準確地判斷多缸內燃機各缸的作功狀況和壓縮狀況，優于目前廣泛使用的曲軸瞬時轉速波動增量n法。分享友人
