ABSTRACT:
A combustion chamber system of a spark-ignition linear engine includes a pre-combustion chamber and a main combustion chamber separated by a combustion control wall. The pre-combustion chamber has a length substantially greater than its width to support the propagation of more organized flame fronts that push unburned fuel and air into the main combustion chamber. The pre-combustion chamber can be arranged to define a multi-stage annular structure comprising a plurality of pre-combustion chamber sections fluidically connected together in an axially stacked array wherein the main combustion chamber can be co-axially housed or accommodated internally within the annular pre-combustion chamber structure.
