直到最近,拖拉机柴油机电起动装置的功率和电瓶容量的选定,只能在制成发动机的试验样机,并在冷室内作过起动试验之后才能进行。因此,制成和供应起动机,电瓶及其他零部件的试验品和产品的日期均要晚于制成发动机试验样机和拖拉机的日期。现在已经能够推荐一些计算方法了,这些方法能以足够的精度计算电起动装置所需要的 Until recently, the selection of the power and battery capacity of the tractor diesel electric starter was made only after a test prototype of the engine was made and a start-up test was carried out in the cold room. Therefore, the date of manufacture and supply of the test articles and products of the starter, batteries and other components is later than the date of preparation of the engine test prototype and the tractor. It is now possible to recommend some calculation methods that can calculate the electric starter required with sufficient accuracy
