Abstract: A fuel cell system of the present invention includes: a fuel cell supplied with fuel gas and oxidizing gas to generate electricity; a fuel gas supply unit supplying the fuel gas to the fuel cell; an oxidizing gas supply unit supplying the oxidizing gas to the fuel cell; an aftercooler cooling the oxidizing gas supplied to the fuel cell by heat exchange with a coolant; an oxidizing gas temperature detector detecting temperature of the oxidizing gas; and a coolant circulation controller starting circulation of the coolant when the detected temperature of the oxidizing gas exceeds a predetermined value. The predetermined value is set to a value of not higher than a minimum electricity generation temperature of the fuel cell, and a circulation timing and flow rate of the coolant for the aftercooler are controlled such that the supplied oxidizing gas does not become cold. This enables the fuel cell to generate electricity at cold start-up.

Abstract: A valve-clearance estimating apparatus estimates a valve-clearance that is a minute spacing between a valve drive element, and a valve element, which form an essential part of a moving body of an electro-magnetically operated valve. A position sensor determining an instant position of the valve drive element, a mass-change estimating portion estimate the mass of the moving body moving together with the valve drive element, and a valve-clearance estimating portion estimates the valve-clearance on the basis of a given position of the valve drive element determined by the position sensor at a time when a change in the mass of the moving body is estimated and when the valve drive element reaches proximate to one of its extreme positions.

Abstract: In an electromagnetically operable engine valve assembly including a controller for an internal combustion engine, a stable initialization is achieved which suppresses a collision of a movable element against an electromagnet to cope with a viscosity of a lubricating oil during an engine start under an engine low temperature. A supplied current value is feedback controlled in accordance with a position of movable element when an initialization control such that a current is continuously supplied to one of electromagnets is executed. At this time, the feedback control gain G1 is, first, set to a relatively small value and is, thereafter, switched to a relatively large value at a gradual pace for each execution of the initialization control until the initialization control has succeeded in moving the movable element to an initial position.
