  "textContent": "A misfire detection device includes processing circuitry configured to execute a stopping process stopping combustion control of an air-fuel mixture in one or more cylinders and a determination process determining whether a misfire has occurred based on a value of a determination subject rotation fluctuation amount, that is, a rotation fluctuation amount of a determination subject cylinder for misfire. A comparison subject rotation fluctuation amount is a rotation fluctuation amount corresponding to a crank angle separated by a predetermined angular interval from a crank angle corresponding to the determination subject rotation fluctuation amount. The determination process includes a process determining the misfire based on a value of the determination subject rotation fluctuation amount when the predetermined angular interval equals an angular interval between crank angles at which compression top dead center appears in the one or more of the cylinders and the determination subject cylinder during the stopping process.",
