关于直流起动机与柴油机的匹配问题,并非启动转速越高越好,超出某一范围,反而是越高越不好。 在某个限度下,直流起动机拖动柴油机的能力越强(可用倒拖转速来表述),便表明起动机的启动能力越强。柴油机的点火靠汽缸的压缩温度,在周围介质温度和汽缸型式已经决定的情况下,汽缸的压缩温度主要取决于压缩时间的长短,即启动转速的高低。启动转速与压缩温度的关系见图1。 On the DC starter and diesel matching problem, not the higher the starting speed the better, beyond a certain range, but the higher the worse. At a certain limit, the stronger the ability of the DC starter to drag the diesel engine (which can be expressed by the reverse speed), the stronger the starter’s starting ability is. The ignition of a diesel engine depends on the compression temperature of the cylinder. When the surrounding medium temperature and the cylinder type have been decided, the compression temperature of the cylinder mainly depends on the length of the compression time, that is, the starting speed. Start speed and compression temperature relationship shown in Figure 1.
