Abstract

PURPOSE: To prevent air-fuel ratios from changing by the change of the amount of providing gas by a method wherein a flow rate control valve is provided on a recirculation passage of blowbye gas and the blow-bye gas is let to return in a suction pipe in proportion to its produced amount.
CONSTITUTION: On the recirculation passage 20 there are provided a valve 24 in order to control flow rates of the flow-bye gas and a pressure-regulating valve 32 in order to control its opening. When the amount of the blow-bye gas increases in a blow-bye gas chamber 18, an upward force is acted on a diaphragm 34 and the pressure-regulating valve 32 moves in a valve-shutting direction. Thus, a strong negative pressure is transmitted to an upper negative pressure chamber 28 and, as a result, opening quantity of the valve 24 increases and a large quantity of blow-bye gas returns from the passage 20 toward a suction manifold 14. Therefore, the pressure in a constant pressure chamber 42 returns to the initial value.
