ABSTRACT:
An engine controller (76) includes a first mode control module (81) for performing a first mode control in which a fuel injection amount in an engine (1) is obtained based on a first torque-engine rotational speed characteristic, and a second mode control module (82) for performing a second mode control in which the fuel injection amount is obtained based on a second torque-engine rotational speed characteristic. The first mode control module (81) has a first engine load estimation part (81a) for estimating an engine load based on a difference in rotational speed between a non-load engine rotational speed and an actual engine rotational speed, and the second mode control module (82) has a second engine load estimation part (82a) for estimating an engine load based on the fuel injection amount.
