摘要:
A control method is provided for an engine for a vehicle. The engine is arranged in association with a fluid coupling having a clutch. According to the control method, the state of engagement of the clutch is first detected. In the next step, it is determined whether or not the vehicle is in a predetermined decelerated operation state. When the clutch has been detected to be in a predetermined state of engagement in the clutch engagement state detection step and in addition, the vehicle has been determined to be in the predetermined decelerated operation state in the decelerated operation state determination step, an output of the engine is increased in the subsequent step.

There can be provided an NiCuZn-based ferrite material containing an iron oxide, a copper oxide, zinc oxide and a nickel oxide in predetermined amounts as main components and a bismuth oxide, a silicon oxide, magnesium oxide and a cobalt oxide in predetermined amounts as additional components. Due to the predetermined amounts of the additional components, the ferrite material has an extremely good temperature characteristic (a change in permeability along with a change in temperature is small), a high quality coefficient Q and high strength.
