ABSTRACT:
An engine system according to the present invention includes an engine and a fuel system that delivers a liquid fuel and a vapor fuel to the engine. A control module communicates with the fuel system and modulates the vapor fuel delivered to said engine based on a determination of a desired vapor fuel rate and a maximum available vapor fuel rate of the fuel system. The control module determines the desired vapor rate based on a mass rate of liquid fuel being delivered to the engine and a coolant temperature of the engine. The control module determines a vapor density by estimating the vapor density based on a temperature of an intake manifold or alternatively receives a signal from a sensor.
