Patent ID: 7111829

Claim:
A method for providing an air/fuel mixture for use in an internal combustion engine, said air/fuel mixture predominantly containing size-limited fuel droplets having a maximum predetermined size, the method comprising the steps of: a) providing a discrete, constrained flow path separate from an induction airflow path of said internal combustion engine, b) providing at least one turbulence-inducing device configured for producing said fuel droplets of said maximum predetermined size with a minimum of fuel vapor in said constrained flow path, c) introducing a flow of gas into said constrained flow path, d) injecting a liquid fuel into said constrained flow path so that said liquid fuel is broken up by turbulence into fuel droplets of said maximum predetermined size, e) mixing said gas and said fuel droplets of said maximum predetermined size with induction air flow in said induction airflow path for burning in combustion chambers of said internal combustion engine, whereby said fuel droplets of said maximum predetermined size burn faster, cleaner and with less detonation than said liquid fuel in a vapor form or in a form other than said droplets of said maximum predetermined size.
