摘要： A vapor fuel recovery system for fuel tanks is provided. The vapor recovery system comprises: a canister that captures vapor fuel expelled from the fuel tank; a vent valve that controls ventilation of vapor fuel from the fuel tank to the canister; and a vent bypass disposed between the canister and the vent valve that controls the flow of vapor fuel from the fuel tank to the on-board recovery canister when a fuel level in the fuel tank is full. The bypass includes a bypass valve and at least one orifice.

摘要： 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.
