ABSTRACT:
A turbocharged engine (20, 20′, 20″, 20′″) counteracts plugging of a diesel oxidation catalyst (DOC48) by causing a first portion of exhaust from one or more exhaust manifolds (26, 28) to enter the DOC after having passed through the turbocharger (30), and causing a second portion of the exhaust (HEG) to enter the DOC without passing through the turbocharger.
