A turbocharged engine ( 20, 20', 20'', 20 ''') counteracts plugging of a diesel oxidation catalyst (DOC 48 ) 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. |
