Intake mixture motion and cold start fuel vapor enrichment system |
摘要 |
An engine system includes an engine having an intake manifold, a cylinder and an intake mixture motion system. The intake mixture motion system includes a plate disposed upstream of the cylinder and an actuator that moves the plate between an open position and a closed position to direct cylinder air flow. The plate is in the closed position for a predetermined period after engine start-up. A fuel system communicates with the engine and supplies a first quantity of liquid fuel to the engine at a first A/F ratio. The fuel system supplies a second quantity of vapor fuel to the engine at a second A/F ratio to provide a fuel mixture having a third A/F ratio during the predetermined period.
