An alternator configured to acquire a motive force from an engine to generate electricity and a capacitor capable of storing therein the electricity generated by the alternator are provided. An electricity consumption amount required during learning is calculated, and a capacitor electricity amount is compared with the calculated electricity consumption amount, and when the capacitor electricity amount is equal to or less than the calculated electricity consumption amount, the alternator is operated to generate electricity until the capacitor electricity amount is increased beyond the calculated electricity consumption amount. On the other hand, when the capacitor electricity amount is greater than the calculated electricity consumption amount, or when the capacitor electricity amount is increased beyond the calculated electricity consumption amount according to electricity generation by the alternator, the learning is performed while using the capacitor electricity without performing electricity generation by the alternator.

Controller and control method for engines

A control device of a diesel engine is provided. The diesel engine includes an injector for injecting fuel into a cylinder, and a turbocharger for compressing intake air by using exhaust energy. The control device includes a calculating module for setting a basic injection timing determined according to an operating state of the engine, as a timing of injecting the fuel from the injector, and an injection control module for injecting the fuel from the injector at the set basic injection timing at least while the engine is in a steady operation.
