三、发动机各冲程流程表格中的A1、B1、C1表示第一组从任意一缸顺时针开始数的3个缸;A2、B2、C2表示第二组从一缸顺时针开始数的3个缸,其中A2与A1平行。表中将每个气缸的4个冲程(1个循环周期)分为12等份,即每个冲程平均分成3等份。“1”为吸气冲程,“2”为压缩冲程,“3”为做工冲程,“4”为排气冲程,“13”表示冲程的三分之一处,“23”表示冲程的三分之二处。表格中的阴影为正在做工的冲程。发动机各冲程流程分别是:1组A缸做功——2组B缸做功——1组C缸做功——2组A缸做功——1组B缸做功——2组C缸做功——1组A缸做功……以此往
Third, the engine stroke stroke table A1, B1, C1 said the first group from any cylinder clockwise start the number of 3 cylinders; A2, B2, C2 said the second group from a cylinder clockwise start of the three Cylinder, where A2 is parallel to A1. The table will be four strokes per cylinder (1 cycle) is divided into 12 equal parts, that each stroke is divided into 3 equal parts. “1 ” for the suction stroke, “2 ” for the compression stroke, “3 ” for the work stroke, “4 ” for the exhaust stroke, “13 ” said the stroke one-third Department, “23 ” said two-thirds of the stroke. The shading in the table is the working stroke. Engine stroke processes are: a group of cylinder A work done - 2 cylinder B cylinder work - 1 cylinder C cylinder work - 2 cylinder A cylinder work - 1 cylinder B cylinder work - 2 cylinder C cylinder work - 1 A group of cylinders to do the work ...... to this
