Abstract: An ignition system for an internal combustion engine having at least one combustion chamber where the ignition system includes a housing, an ignition device, an injector, and a pre-chamber having a nozzle disposed spaced from the proximal portion of the pre-chamber. The igniter portion of the ignition device and the nozzle of the injector are operatively supported in the proximal portion of the pre-chamber and disposed flush therewith. The igniter portion ignites the fuel in pre-chamber such that partially combusted pre-chamber products are forced through orifices in the pre-chamber nozzle and extinguish, but dispersed through the combustion chamber so as to ignite the main fuel charge therein.

Abstract: A fuel injection system for an engine is described. The fuel injection system includes a prechamber assembly mounted on a cylinder head of the engine. The prechamber assembly includes a prechamber located upstream of a combustion chamber of the engine and configured to receive air-fuel mixture. Further, the prechamber assembly includes a fuel injector to controllably supply fuel into the prechamber, where the supplied fuel mixes with the air-fuel mixture to form a homogeneous mixture of air and fuel at a predefined stoichiometric ratio. The prechamber assembly also includes a spark plug disposed at a downstream region of the prechamber, the downstream region being proximal to the combustion chamber of the engine. The fuel injection system also includes a controller operably coupled to the fuel injector, where the controller is configured to control the predefined stoichiometric ratio of air to fuel in in the prechamber.

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.
