EXHAUST EJECTOR TUBE FOR ENGINE SYSTEM

摘要

An exhaust ejector tube is disclosed for use with an engine system. The exhaust ejector tube may have an exhaust pipe with an upstream end, a downstream end, and a plurality of flutes formed at the downstream end. Each of the plurality of flutes may have a rounded end that tapers toward the downstream end. The downstream end of the exhaust pipe terminates partway along a length of the plurality of flutes. The exhaust ejector tube may also have an ejector pipe with a smaller diameter than the exhaust pipe that intersects with the exhaust pipe. The second ejector pipe may have an upstream end located outside the exhaust pipe, and a downstream end located inside the exhaust pipe at the plurality of flutes.
