摘要： A structure is mounted in a water jacket for a cylinder block of an engine. The structure includes a body forming a housing mounting portion including a panel formed in an arc shape so as to have inner and outer curved surfaces to be surrounded by a block bore. A pad-housing is formed in a plate shape to have curved surfaces with a curvature equal to the inner and outer curved surfaces of the housing mounting portion. The pad-housing is inserted into a housing mounting hole and is formed in a shape to correspond with the housing mounting hole. A pad is formed in a shape to correspond with a pad mounting hole which is bored through the pad-housing through. The pad has a curved surface and is inserted into the pad mounting hole to achieve water tightness.

摘要： An internal combustion engine includes a state determination device. The state determination device includes a storage device and an execution device. The execution device executes an acquisition process, and a determination process. The execution device executes a guard process of bringing an internal combustion engine state variable closer to an allowable range or a value within the allowable range when the internal combustion engine state variable acquired in the acquisition process is out of the predetermined allowable range. The execution device determines the state of the internal combustion engine based on the internal combustion engine state variable after the guard process in the subsequent determination process when the guard process is executed.
