Abstract
An engine system includes an engine housing including a plurality of intake valve openings, an intake port extending to the plurality of intake valve openings and an injector bore extending to the intake port. The engine system also includes a fuel system having a port fuel injector, and a fuel distributor having a baffle wall. The baffle wall extends into the intake port and extends at least partially around a fuel spray axis, forming a fuel channel and having at least one of a circumferentially varied porosity or an axially varied cross sectional area. The baffle wall shields fuel spray of an injected fuel such as methanol to limit a bias in distribution of fuel among the plurality of intake valve openings.
