exhaust advance 中文意思是什麼
exhaust advance
解釋
排氣提前-
But the temperature difference at the vertical direction in combustion chamber in lead column, that is said by operator, is over 60 ?. ( 2 ) according to the experiences in the practice, the second layer air and the second layer gas had a little effect of support burning, and the third air has little effect for combustion, and the power to drawing exhaust gas can only be adjusted in limited range. the problems, it is said above, restricted more advance of some kinds of technology and economy target in spelter refining in new jersey furnace
由於鋅精餾爐產量提高，一些問題開始暴露出來： （ 1 ）燃燒室?舶要求溫度差不超過10 ，而從現場反映的情況來看，燃燒室上、中、下部溫度差已超過60 ； （ 2 ）在生產實踐中，發現燃燒室第二層空氣、第二層煤氣作用甚小，第三層空氣失去助燃作用，廢氣出口的抽力可調范圍有限；以上這些問題在客觀上制約了精餾塔在鋅精煉中各項技術經濟指標的進一步提高。 -
The best compression ratio and fuel injection advance angle are calculated through mess optimization calculation program of language c. on the basis, optimization simulation of inlet and exhaust timing has been carried with the diesel engine working model to increase diesel engine ' s volumetric efficient
在此基礎上，利用柴油機工作過程模型，對進排氣正時進行了優化計算，以提高柴油機的充氣效率，改善燃燒性能，為進一步改善該機性能指明了方向。 -
So it is proved that the working model is right, and on the basis, the influences of the compression ratio and fuel injection advance angle on the diesel engine ' s combustion performance are studied. ( 2 ) energy resource and environment protection are two important problems that diesel engine is faced with. so in this paper the constrained optimization is studied in order to decrease fuel consumption within the limitation of the regulation on exhaust emission and power output
（ 2 ）能源和環境保護是柴油機存在和發展的兩大問題，因此本文在滿足排放法規及柴油機動力性的基礎上，以降低油耗為主要研究目標，進行有約束條件的優化計算，並提出了一種新的柴油機工作過程優化計算方法? ?非線性回歸?網格法。 -
On the basis of looking up domestic and foreign literatures and consulting the facts of repairing factory, with 495t diesel engine machine as the study object and the fuel delivery advance angle as the study factor, this thesis has probed into the effect of the deviation of fuel delivery advance angle in each cylinder on exhaust and other performance of engine
本文在查閱國內外文獻及參考修理廠實際情況的基礎上，以修理后的495t直噴式柴油機為研究對象，以供油提前角為研究因素，探討發動機各缸的供油提前角偏差情況對排放及其它性能的影響。 -
