Abstract
An igniter system for a reciprocating piston internal combustion engine having one or more cylinders including at least one igniter per cylinder is disclosed. The igniter system can comprise: a combustion chamber connected to a main cylinder of the engine by a restricted diameter bore, wherein a lean burn fuel mixture is introduced into the combustion chamber by the normal compression stroke of the engine; a hydrogen valve that injects a hydrogen rich gas into the combustion chamber forming a mixture of hydrogen and air having a hydrogen concentration above the stoichiometric ratio for hydrogen and air in the combustion chamber; and a spark ignition source that injects hot unburned hydrogen into the main cylinder, thereby initiating ignition.

An igniter system for a reciprocating piston internal combustion engine having one or more cylinders including at least one igniter per cylinder, the igniter system comprising:
- a combustion chamber connected to a main cylinder of the engine by a restricted diameter bore, wherein a lean burn fuel mixture is introduced into the combustion chamber by the normal compression stroke of the engine;
- a hydrogen valve that injects a hydrogen rich gas into the combustion chamber forming a mixture of hydrogen and air having a hydrogen concentration above the stoichiometric ratio for hydrogen and air in the combustion chamber;
- and
- a spark ignition source that injects hot unburned hydrogen into the main cylinder, thereby initiating ignition.
An igniter system for a reciprocating piston internal combustion engine having one or more cylinders including at least one igniter per cylinder, the igniter system comprising:
- an igniter tube having an internal bore having a restricted diameter;
- a combustion chamber connected to a main cylinder of the engine by the igniter tube, wherein air is introduced into the combustion chamber by a normal compression stroke of the engine;
- a hydrogen valve that injects a hydrogen rich gas into the combustion chamber forming a mixture of hydrogen and air;
- and
- a spark ignition source that fires the mixture either before, on or after Top Dead Center.
