To accurately detect the combustion pressure generated in a cylinder.
In this engine, the combustion pressure generated in the cylinder 10 is detected with the pressure sensor 50 arranged at a joining part of a cylinder head 20 and a cylinder block 30. To put it concretely, the pressure sensor 50 is arranged at a sensor notch 42 formed at a gasket member 41 put between the cylinder head 20 and the cylinder block 30. A communication notch 22 for providing communication between the inside of the cylinder 10 and the pressure sensor 50 with a space (pressure introduction port 23) without a restriction is formed on an opposing surface (lower surface) to the pressure sensor 50 at the cylinder head 20. Thus, the communication between the inside of the cylinder 10 and the pressure sensor 50 can be provided with a sufficiently large space. Then, the combustion pressure generated in the cylinder 10 can be accurately detected.
