摘要： Various systems and method for heating an engine in a vehicle are described. In one example, intake air flowing in a first direction may be heated via a gas-to-gas heat exchange with exhaust gases. The heated intake air may then be used in a subsequent gas-to-liquid heat exchange to heat a fluid circulating through the engine. In another example, intake air flowing in a second direction may be heated via a heat exchange with exhaust gases in order to cool an exhaust catalyst.

摘要： A method for operating an engine with a fuel reformer is presented. In one embodiment a method for operating an engine by injecting a gaseous fuel and a liquid fuel to at least an engine cylinder is presented. The method may prioritize the injection of the gaseous fuel in response to an amount of gaseous fuel stored in a fuel storage tank.
