结合生产经验,讨论了同等材质、同样功率条件下六缸发动机排气岐管流道形状、圆弧过渡曲率半径、局部壁厚、使用环境等因素对排气岐管寿命周期的影响。提出了圆形或椭圆形流道优于方形流道,圆弧过渡曲率半径大较优,热作用区部位使用较大壁厚等观点。
Combining with production experience, the influence of exhaust manifold manifold shape, curvature radius of circular arc, partial wall thickness and service environment on the life cycle of exhaust manifold under the same power and same power is discussed. Proposed circular or oval flow channel is superior to the square flow channel, arc transition radius of curvature is superior, the thermal role of the site of the larger wall thickness point of view.
