０に圧力を与え、ガス漏れを防いでいる。2. Description of the Related Art FIG. 4 shows a single-plate type head gasket 10 of an engine according to the prior art, which is made of a carbon steel plate (SPC), and has a circumferential projection 2b on the upper surface of a flange 2a as shown in FIG. The cylinder head 4 is clamped between the cylinder liner 2 and the cylinder block 3 and the cylinder head 4, the head bolt 5 is tightened, and the cylinder head 4 is mounted on the cylinder block 3.
Pressure is applied to zero to prevent gas leakage.

側Ｐ3 は非常に高くなる反面、シリンダヘッド側Ｐ4 は
低く、シリンダヘッド側よりのガス漏れの危険性が多
く、エンジン性能の低下を来す課題がある。Due to the above structure, the surface pressure applied to the cylinder liner 2 and the cylinder liner 4 becomes extremely high on the cylinder liner side P3 as shown in the pressure distribution diagram in FIG. The cylinder head side P4 is low, and there is a high risk of gas leakage from the cylinder head side, which causes a problem of lowering engine performance.

部に対応する位置に、凸部を備えた構成とする。Means for Solving the Problems A concave portion is provided on the back surface of a single steel plate type head gasket so as to surround a circumferential projection provided on the upper surface of a flange portion of a cylinder liner, and the front surface corresponds to the concave portion on the back surface. The position is provided with a convex portion.

れて作用し、ガス漏れの防止に多大の効果を表す。According to the above structure, as shown in the surface pressure distribution diagram in FIG. 3, the surface pressure P1 applied to the cylinder liner side and the surface pressure P2 applied to the cylinder head side are determined by the unevenness of the single-plate steel head gasket 1. 1a and 1b are connected to the protrusions 2b of the liner liner.
By shifting Θ (30 ° ~ 80 °) from the upper outer edge of
The effect of the projecting portion 2b of the cylinder liner 2 and the effect of the uneven portions 1a and 1b of the single steel plate type head gasket 1 act synergistically to show a great effect in preventing gas leakage.
