在汽油发动机中,点火间隙关闭以让电流通过点火线圈的时间段

In a petrol engine, the period of time the ignition points are closed to let current flow through the ignition coil in between each spark. This is measured as an angle in degrees around the camshaft in the distributor which controls the points, for example in a 4-cylinder engine it might be 55° (spark at 90° intervals, points closed for 55° between each).
