Abstract

An ignition combustion pre-chamber for igniting an air-fuel mixture in an internal combustion engine which operates in conjunction with an engine management system to maintain an ideal stoichiometric air-fuel ratio in the pre-chamber throughout the complete operating range of the engine. A one-way check valve admits a separate air-fuel mixture into the pre-chamber which, after mixing with the portion of the air-fuel mixture of the main combustion chamber which necessarily enters the pre-chamber during the compression stroke of the engine, results in an ideal stoichiometric mixture receptive to quick ignition and faster flame front propagation throughout the main combustion chamber. In a second embodiment, the pre-chamber is separated from the main combustion chamber by a second one-way check valve which prevents mixing of the separate air-fuel mixtures during the compression stroke, allowing a constant stoichiometric air-fuel ratio to be introduced into the pre-chamber and ignited. Alternate gaseous fuels can also be used with the pre-chamber.
