Abstract

Methods and systems are provided for reducing exhaust temperatures during high engine load conditions in engine systems configured to operate with multiple fuels. Stoichiometric cylinder operation is provided via injection of a gaseous fuel such as CNG. In response to elevated exhaust temperatures, the cylinder is enriched by injecting a liquid fuel, such as gasoline, while maintaining the injection of CNG and while maintaining spark timing at MBT.
