| 摘要 |
A control device of a diesel engine, including an acceleration detector including an acceleration sensor, the acceleration sensor being attached to an engine body that defines a combustion chamber, the acceleration detector configured to output a vibration acceleration, an integrator configured to integrate values corresponding to amplitudes of the vibration acceleration from a predetermined integration start timing that is at least before an ignition timing, a comparison unit configured to compare an integration value of the integrator with a predetermined ignition timing judgment level, and a real ignition timing judgment unit configured to judge a real ignition timing on the basis of a reach timing, at which the integration value has reached the ignition timing judgment level.
