    摘要： A fuel control system is provided including a fuel tank, a purge vapor canister, a vapor line, and a fuel injector connected to an internal combustion engine. A purge vapor canister vent valve seals the purge vapor canister from the atmosphere such that the fuel tank, purge vapor canister, and fuel injector form a closed system. Upon initial starting of the engine, the purge vapor pressure is such that the purge vapor is drawn to the fuel injector from the dome portion of the fuel tank after passing through the purge vapor canister. Simultaneously therewith, the amount of liquid fuel is reducing or increasing by an amount of equally increasing or decreasing, respectively, vapor fuel so that a necessary mass flow rate is achieved to support combustion. As the amount of fuel vapors decreases to a negligible amount, combustion is supported by the atomization of liquid fuel. The delivery of the liquid fuel and vapor fuel is completed through the use of a fuel injector to accommodate both liquid and vapor form of fuel.

    摘要： A method is provided for enriching a fuel to air ratio in an engine during acceleration based on a known fuel multiplier. Initially, the method retrieves the fuel multiplier from a dynamic crankshaft fuel control (DCFC) system. This system uses the fuel multiplier to reduce the amount of fuel delivered to the engine. When acceleration is desired, the method increases the overall acceleration enrichment values as a function of the DCFC fuel multiplier. Thus, when the vehicle is launched via a throttle tip-in while the DCFC system is active, the acceleration enrichment values are increased thereby improving drivability by having combustion taking place in a richer environment.

    摘要： A method of adjusting idle spark for an individual cylinder of an internal combustion engine in an automotive vehicle including the steps of determining a crankshaft acceleration for an individual cylinder of the internal combustion engine and determining an average acceleration error for the individual cylinder based on the determined crankshaft acceleration. The method also includes the steps of determining an adaptive spark advance for the individual cylinder based on the determined average acceleration error and determining a new spark advance for the individual cylinder based on the determined adaptive spark advance and a nominal spark advance. The method further includes the steps of adjusting idle spark for the individual cylinder based on the new spark advance for the individual cylinder.

    摘要： An engine induction system resonator that is designed to minimize emitted engine noise. The resonator includes an enclosed tube that has a first diameter and that defines a resonant chamber therein. The resonator also includes a pipe that has a second diameter smaller than the tube diameter. The pipe extends axially through the tube and has first and second ends that connect to other induction system components to channel inductive air flow therethrough. The pipe defines a plurality of perforated holes distributed along a section of the pipe housed within the tube. The plurality of perforated holes is distributed along the pipe in a manner that minimizes emitted engine noise. The resonator is designed in view of other system components to minimize overall system cost and overall required system implementation area.
