Abstract
A vehicle system comprises an internal combustion engine including a PCV system fluidly coupled to a gaseous fuel source via a flow control valve. The gaseous fuel source may be fluidly coupled to an air inflow line of the PCV system, and the flow control valve may be configured to control a flow of gaseous fuel into the PCV system.
