Abstract: Atomic oxygen is provided for the purpose of promoting reliable ignition and smooth combustion in a spark ignition internal combustion engine is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the flammable mixture of air and gasoline vapor prior to the time of ignition. The introduction of N2O may take place in the intake manifold, in the stream of exhaust gas being returned as part of the EGR process, or directly into the combustion chamber (for example through a small orifice in the base of the spark plug or through a small nozzle located elsewhere in the cylinder head). Introduction of N2O directly into the combustion chamber may be continuous, or it may be pulsed so as to occur at the time of, or shortly before, spark ignition.

Abstract: One approach to providing atomic oxygen for the purpose of promoting more rapid and compact combustion is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the compressed air in the cylinder before or close to the time of ignition. The introduction of N2O may take place in the intake manifold, directly into the combustion chamber through a small orifice in the base of the fuel injector or a small nozzle located elsewhere in the cylinder head, or the N2O can be added as a solute to the injected fuel.
