Engine control apparatus

An engine control apparatus for an engine mounted to a working vehicle, the working vehicle being a combination of a vehicle and a working machine, the engine control apparatus comprising:

• a fuel injection apparatus configured to inject a fuel to the engine;
• detecting means which detects a drive state of the engine, including rotating speed and torque;
• an identification circuit having a setting that identifies a vehicle type and a working machine type of the working vehicle;
• a first data storage circuit that stores a first output characteristic data set for the engine based on said rotating speed and said torque;
• a second data storage circuit that stores a second output characteristic data set, which is a correction to the first output characteristic data set, based on said rotating speed and said torque and further based on said identified vehicle type and said identified working machine type of said working vehicle;
• and
• an ECU which tests said identification circuit, the ECU having a first configuration to actuate the fuel injection apparatus that is based on said detected drive state and data read from the first output characteristic data set when testing of said identification circuit results in a first detected configuration of the working vehicle, and having a second configuration to actuate the fuel injection apparatus that is based on said detected drive state and data read from the first output characteristic data set and the second output characteristic data set in response to said rotating speed and torque when testing of said identification circuit results in a second detected configuration of the working vehicle.
