Document Type and Number:
WIPO Patent Application WO2000040463
Kind Code:
A9
Abstract:
An anti ingestion device for use with an engine, preferably a marine engine. The device comprises an exhaust manifold (20) or riser system for exhausting engine gases, wherein the exhaust manifold (20) has a first end (22) and a second end (24), and the first end (22) is connected to a cylinder head (12). There is a one-way pressure relief valve (30) having a first end (32) and a second end (34), wherein the first end (32) is coupled to the exhaust manifold (20) and the second end (34) is exposed to atmospheric pressure. An air inlet line (40) is coupled to the second end (34) of the one-way pressure relief valve (30), such that the air inlet line (40) serves as a conduit for guiding atmospheric pressure to the one-way pressure relief valve (30), thereby providing atmospheric pressure for passage into the exhaust manifold (20).
