<p>The present invention provides an engine life predicting apparatus at low costs and with high reliability. A current detector (41) and a voltage detector (42) respectively detect a current value and a voltage value outputted from an engine generator (1). An operating block (5) determines a weight constant on the basis of the current value and the voltage value, weights the operating time of an engine (11) by using the weight constant, and integrates the weighted operating time to calculate an integral time. A judging block (6) compares the integral time and a reference time, and gives a notification to an indicator (8) when it judges that the integral time exceeds the reference time. Receiving the notification, the indicator (8) makes an external indication. The current detector (41) and the voltage detector (42) can be made of electric circuitry, so that the life of the engine can be predicted at low costs and with high reliability.</p> |
