Abstract

See full text

An engine system includes a cylinder block, and a cylinder head attached to the cylinder block and including exhaust ports. Exhaust collection passages are formed in the cylinder head and each fluidly connect to one of the exhaust ports. An unburned hydrocarbon (UHC) emissions mitigation conduit fluidly connects to the exhaust ports to route UHC to an oxidation catalyst or for recirculation.
