Abstract

PURPOSE:To improve treating ability of blowby gas during a period of a cool engine by making increasing correction on pressurized air amount during the period of the cool engine when the blowby gas amount is increased, in the case of blowing out the blowby gas into an exhaust passage by pressurized air in a supercharger. CONSTITUTION:In a blowby gas passage 14, the upper flow end of which is connected to the crank case of an engine 1 through an oil separator 15 and the other end of which is connected to the downstream side from a pressure wave supercharger 5 in an exhaust passage 4, an ejector 16 is interposed near the downstream end. This ejector 16 is composed so that the blowby gas can be sucked in and discharged in the exhaust passage 4 by using the pressurized air as a driving fluid by means of the pressure wave supercharger 5. A needle (omit in the drawing) is provided in the injection nozzle 19 of the ejector 16, for adjusting the opening area of its top end part. The forward and backward moving amount of the needle can be controlled so as to increase air supply amount during period of the cool engine when the engine temperature detected by a temperature sensor is low in comparison with the air supply amount during the period give hot engine.
