This patent describes an engine system including an exhaust manifold; a turbocharger having a scroll into which exhaust gas from the engine is introduced; a valve for selectively by-passing exhaust gases from the manifold around the scroll into an exhaust conduit; and a particulate separation device operatively interposed between the exhaust manifold, the scroll and the valve, the separation device comprising; a chamber; a first port which establishes fluid communication between the chamber and the manifold; a second port, the second port establishing fluid communication between the chamber and the scroll; and a third port, the third port establishing fluid communication between the chamber and the exhaust conduit via the valve; the chamber including means for inducing particulate matter which is carried thereinto from the manifold through the first port to separate from the exhaust gases and gravitate toward the third port and for inducing particulate matter free exhaust gases to pass through the second port.
