| description | The utility model discloses a cylinder body of an engine. The cylinder body of the engine is provided with a water jacket (11), a cylinder cover installation hole (12) and a main bearing cover bolt hole (13), wherein the cylinder cover installation hole (12) is a threaded hole, a thread segment of the cylinder cover installation hole (12) extends from the position of the bottom of the water jacket (11) to one side of the cylinder body, where the main bearing cover bolt hole (13) is located, for a preset length, and the vertical distance between the axis of the cylinder cover installation hole (12) and the axis of the main bearing cover bolt hole (13) is equal to the minimum allowable value. By adopting the above structure of the cylinder body of the engine, acting force on a cylinder hole is small, and then the cylinder hole is prevented from deforming, and accordingly circular and cylindrical degrees of the cylinder hole are guaranteed, the problems that a cylinder is drawn, an air leak amount is large, engine oil burns and the like are prevented from occurring, and furthermore work performance of the engine is improved. The utility model further discloses the engine. |
