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.
An electronically controlled internal combustion engine system including an engine having a plurality of cylinders for burning a combustible mixture wherein the density of the combustible mixture provided to the cylinders is increased by adding nitrous oxide and additional fuel to the combustible mixture, said engine system comprising:
A nitrous oxide delivery and engine control system for an internal combustion engine having a set of cylinders for burning a combustible mixture including a quantity of fuel wherein the density of the combustible mixture provided to the set of cylinders is enhanced by adding nitrous oxide stored in a nitrous oxide container via a nitrous oxide supply outlet and additional fuel to the combustible mixture via a set of fuel injectors mounted proximate the cylinders, said nitrous oxide delivery and engine control system comprising:
A method for controlling an internal combustion engine system having a plurality of cylinders for burning a combustible mixture including nitrous oxide, the internal combustion system including a nitrous oxide container, a nitrous oxide supply outlet, a nitrous oxide flow regulator, a set of fuel injectors mounted proximate the cylinders, and an electronic control unit (ECU) for controlling operation of the internal combustion engine system, said method comprising the steps of:
