It is recommended that the pressure gas be introduced through a liquid reservoir space part 10. Thus it is possible to obtain a molding with less bubbles and with the fiber-reinforcing material 11 impregnated with the liquid resin material 12 satisfactorily.

Abstract: PURPOSE:To maintain a stable condition of idling even when a load applied to an internal combustion engine has rapidly changed, by providing a control valve opening timing determination means and the like and thereby ensuring a specified valve opening time length for each cylinder in consideration of the number of engine revolutions and the load applied to the engine. CONSTITUTION:The apparatus has a control valve opening timing determination means I. In this means I, when the valve opening time length calculated by a control valve opening time length calculator G is smaller than a specified valve opening time length determined from the number of revolutions of an internal combustion engine, a valve opening timing for a control valve C is determined from a valve opening time length calculated on the basis of a control valve closing timing set beforehand and fixed at a time prior to an intake valve opening timing. On the other hand, when the former is larger than the latter, the valve opening timing for the control valve C is determined from said latter, i.e., the number of engine revolutions. And a specified valve opening time length is ensured for each cylinder in consideration of the number of engine revolutions and the load applied to the engine. This can maintain a stable condition of idling even when the load has rapidly changed.
