查询词典 basic angle

The optimized exhaust lag angle and intake advance angle of the EQ6100 engine are calculated by means of alternated one dimension searching method vary with engine operating conditions.

采用轮流一维搜索法，计算出随EQ6 10 0发动机工况变化的优化的排气门延迟关闭角和进气门提前开启角。

The ignition delay period is controlled by the fuel injection advance angle which is an important parameter. If the advance angle of injection is adjusted earlier, the density of the combustion chamber is small and its temperature is low, when the fuel is injected into the combustion chamber. So it needs long time to atomization.

喷油提前角是影响燃烧滞燃期的重要参数，喷油提前角的大的工况，燃油喷入燃烧室时缸内空气的密度小，温度低，燃油雾化所需时间长，sauter平均直径大，油滴汽化的表面积越小，所以油束雾化效果不好。

According to the measured pressure data of the four-stroke small utility gasoline engine, the cyclical variations of the maximum pressure, the crank shaft angle at the maximum pressure, the mean indicated pressure and the largest pressure rise rate were analyzed. Meanwhile, the influences of ignition advance angle, load and rotation speed on cyclical variation were also investigated.

根据实测小型通用四冲程汽油机气缸压力，分析了最大爆发压力、最大爆发压力所对应曲轴转角、平均指示压力以及最大压力升高率等参数的循环波动特性，以及点火提前角、负荷和发动机转速对循环波动的影响。

The apparatus adopts the technique of one-chip computer,can set ignition advance angle at random rev of the engine at any time and assists the power test of the engine.The apparatus can survey and describe the best ignition advance angle curve of motorcycle engine and affords gist for the design of motorcycle engine and ignition control.

该仪器采用单片机技术，能够在任意发动机转速下设定任意点火提前角，配合发动机测功试验，可以快速测绘出摩托车发动机最佳点火提前角曲线，为发动机和点火器设计提供依据。
