ENGINE CONTROLLER

The present invention aims at providing an engine control apparatus which improves a general purpose property of an ECU (11) with respect to a one type engine (70). The engine control apparatus of the present invention is provided with an engine (70) which is mounted to a working vehicle, a fuel injection apparatus (117) which injects a fuel to the engine (70), detecting means (14, 16) which detects a drive state of the engine (70), and an ECU (11) which controls an actuation of the fuel injection apparatus (117) on the basis of a detection information of the detecting means (14, 16) and a specific output characteristic data (M1) of the engine (70). Compensating means (21) for compensating the output characteristic data (M1) is provided. The ECU (11) is structured such as to compute a limit torque value on the basis of a result of compensation of the output characteristic data (M1) by the compensating means (21) and the detection information of the detecting means (14, 16), and actuate the fuel injection apparatus (117) in correspondence to the limit torque value.
