ABSTRACT:
A combined fuel vapor injector and igniter system for internal combustion engines and method of operating the engine therewith in which liquid fuel enters an injector-igniter device, is vaporized using the engine's heat of combustion, and exits in vapor form into the engine combustion chamber where it mixes with air or an air-fuel mixture which has entered through an intake valve, or port, and the resulting air-fuel mixture is ignited. The system assures reliable ignition, so that engines may be run at leaner than stoichiometric air-fuel ratios to take advantage of increased fuel economy, and reduced emissions of the oxides of nitrogen hydrocarbons and carbon monoxide. Power output equalization is attained between cylinders.
