Abstract
An internal combustion engine system that is selectively powered by an enhanced air/fuel mixture. The supply of fuel to the cylinders of an internal combustion engine is increased in response to the addition of a supplemental oxidizing agent into an air/fuel mixture. The additional fuel may be added by increasing the duty cycle of fuel injectors mounted proximate the individual cylinders. In addition, the ignition timing is adjusted in accordance with the change in the density of the air/fuel mixture. The amount of supplemental oxidizing agent provided to the cylinders may be regulated by increasing in a controlled manner the rate at which the supplemental oxidizing agent is supplied over a period of time. Furthermore, the control unit for the engine receives and responds to a number of external operating parameters including the oxygen content of the engine exhaust and the traction of the tires.
