A predetermined margin torque is set such that it is possible to maintain a predetermined engine idling speed by adjusting ignition timing with respect to load fluctuations during idling operation. The margin torque is set to decrease, as a load, acting on...

An engine controlling apparatus includes an idle speed setting unit (2a) that sets a target idle speed upon idling of an engine mounted on a vehicle, and a target torque setting unit (2a) that sets a target torque in response to the target idle speed. The ...

Torque generated by the engine is obtained as engine generated torque TQe. Load torque applied to the engine is obtained as estimated engine load torque TQf. The difference between the engine generated torque TQe and the estimated engine load torque TQf is...

A controller controls an amount of fuel supplied to an internal combustion engine of a vehicle. The controller restricts the fuel supply amount, which is requested for the engine, in accordance with a fail-safe limit value set correspondingly to an operati...

The method involves controlling the auxiliary device (3) so as to reduce resonant natural oscillations of the internal combustion engine (2) relative to the body (5). The auxiliary device is controled so as to minimize the periods spent in critical revolut...
