A process of operating a spark-ignited internal combustion engine (SI-ICE) with improved fuel efficiency and reduced emissions including under steady state and under lean-operating conditions at high overall air to fuel (AFR) ratios. A first supply of high octane hydrocarbon fuel, such as gasoline or natural gas, and a first supply of oxidant are fed to a fuel reformer to produce a gaseous reformate with a reforming efficiency of greater than 75 percent relative to equilibrium. The gaseous reformate is mixed with a second supply of oxidant, after which the resulting reformate blended oxidant is fed with a second supply of high octane hydrocarbon fuel to the SI-ICE for combustion. Steady state fuel efficiency is improved by more than 3 percent, when the reformate comprises from greater than about 1 to less than about 18 percent of the total volume of reformate blended oxidant fed to the engine.

Embodiments of the present disclosure may include a system for delivering oxygen to an internal combustion engine of a vehicle including an air filter for removing contaminants from an ambient air source. Embodiments may also include a main air supply pump driven by a first rotational power source to produce pressurized high temperature air. In some embodiments, the first rotational power source may be powered by an internal combustion. Embodiments may also include an engine of the vehicle. In some embodiments, the air filter may be in pneumatic communication with the main air supply pump generating the pressurized high temperature air. Embodiments may also include a heat exchanger for lowering a temperature of the pressurized high temperature air to produce pressurized cold temperature air.

This invention provides a method and system for providing an oxygen-enriched air stream to the cabin and/or internal combustion engine of a vehicle. The benefits of such an approach include increased fuel efficiency and reduced emissions in the internal combustion engine and increased driver alertness and comfort for the vehicle operator. The oxygen-enriched air stream is provided by a membrane separation system, a pressure swing adsorption system, vacuum swing adsorption, or other methods. The delivered oxygen-enriched air is controlled to a prescribed level using sensors, valves, and controllers.
