Figure 1 is a sectional view showing the main parts of the cylinder liner of the present invention, Figure 2 is a diagram showing the relationship between oil film thickness and piston stroke when the wave depth is constant, and Figure 3 is a diagram showing the relationship between the oil film thickness and piston stroke when the wave pitch is constant. Figure 4 shows a combination of Figures 2 and 3, Figure 5 is a cross-section of the cylinder of a typical marine diesel engine. FIG. 6 is a partially enlarged view of FIG. 1. 1 is a cylinder liner, 2 is a piston, 3 is a piston ring, 5 is a convex portion, and 6 is a concave portion.
Claims (1)
凹凸によつて摺動方向にウエーブ形状を形成した
シリンダライナにおいて、全領域に関しウエーブ
ピツチをピストンリング幅以下とし、ピストンの
上下死点領域のウエーブ深さより浅くしたことを
特徴とするシリンダライナ。 In a cylinder liner in which a wave shape is formed in the sliding direction by continuous unevenness on the inner circumferential surface on which the piston ring slides, the wave pitch is set to be less than or equal to the piston ring width in the entire area, and the wave shape in the top and bottom dead center areas of the piston is A cylinder liner characterized by being shallower than it is deep.
