气缸盖螺旋进气道的新计算－试验方法要研制固定工况的气缸盖螺旋进气道，就要解决两个问题：一是确定发动机气缸内充量的最佳涡流强度；二是在气缸充气损失最小时保证所需的涡流。至今仍没有一种方法可解决这两个问题，即：要解决第一个问题，调好的最终螺旋进气道与其雏... New Calculation of Cylinder Head Helical Inlet - Test Method To develop a helical inlet of a cylinder head in a fixed condition, two problems must be solved: one is to determine the optimum swirl intensity of the charge in the cylinder of the engine; The minimum loss of inflation to ensure the required eddy current. So far there is no way to solve these two problems, namely: to solve the first problem, tune the final spiral inlet and its ...
