ジヤのオーバラン防止装置。 means for detecting the rotational speed of the turbocharger;
a first comparator that compares the rotational speed with the upper limit rotational speed and outputs a first output when the rotational speed of the turbocharger exceeds the upper limit rotational speed; a differentiator that calculates rotational acceleration from the rotational speed of the turbocharger; a second comparator that compares the rotational acceleration output from the differentiator with a rotational acceleration upper limit value and outputs a second output when the rotational acceleration exceeds the rotational acceleration upper limit value; An AND circuit that outputs an abnormal signal when input, and an AND circuit that is activated by the abnormal signal.
A turbocharger overrun prevention device comprising a bubble that causes a portion of exhaust gas from an engine to bypass a turbine and be released.
