  • DIAGNOSIS DEVICE AND DIAGNOSIS METHOD FOR INTERNAL COMBUSTION ENGINE, AND CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
    Publication number: 20200063678
    Abstract: A diagnosis device for a multi-cylinder internal combustion engine having an exhaust turbocharger, the device configured to diagnose a fuel combustion state in each one of cylinders in the internal combustion engine. The diagnosis device includes: a rotational speed detector configured to output a signal corresponding to a rotational speed of the exhaust turbocharger or a signal correlated to fluctuation in the rotational speed of the exhaust turbocharger, and a fuel combustion state diagnosis unit configured to diagnose unevenness in the fuel combustion states of the cylinders through a frequency analysis involving a fast Fourier transformation of a frequency characteristic of a signal output from the rotational speed detector.
