Cylinder gasket of engine

The invention relates to a cylinder gasket of an engine. The cylinder gasket of the engine is of an integrated structure. At least four cylinder holes corresponding to air cylinders are formed in the cylinder gasket in sequence, and seven water outlet holes are formed in the side, opposite to a cylinder body water inlet pipe, of the cylinder gasket; an eighth water outlet hole is formed in the side, where the cylinder body water inlet pipe is located, of the cylinder gasket, and the water outlet holes are completely different in bore diameter. The bore diameters of water inlet holes are gradually increased from one end of a cylinder body water inlet to the other end of the cylinder body water inlet, a water outlet hole is additionally formed in the tail end of the cylinder gasket, therefore, the situation that flow of the water outlet holes is uneven due to the fact that pressure of cooling water in the water inlet decreases can be effectively avoided, and further the problem of too much gas is produced is solved.
