    摘要: Methods and systems are provided for fuel systems including a gaseous fuel. Temporary flow restrictions in the fuel line of a first gaseous fuel may be addressed by temporarily shifting to cylinder operation with a second liquid fuel. Upon resumption of first fuel operation, if the flow restriction persists, a diagnostic code may be set and cylinder operation with the second fuel may be restarted.

    摘要: Systems and methods for monitoring a fuel reformer which reforms ethanol into a reformate gas comprising H2, CO, and CH4 for fueling an engine are provided. Degradation of the fuel reformer may be indicated based on an amount of ethanol injected into the fuel reformer and an amount of at least one of H2, CO, and CH4 produced by the fuel reformer.
