Abstract
An engine includes pistons, cylinders, combustion chambers, and intake lines. The engine also includes at least one port fuel injector, a flow guide plate, spark plugs, prechambers housing the spark plugs, and exhaust lines. The pistons are actuated by combustion reactions. The cylinders house the pistons. The combustion chambers form containment boundaries for the combustion reactions. The intake lines form an intake manifold and provide an air fuel mixture to the combustion chambers. The flow guide plate directs the air-fuel mixture to a specified location with the corresponding combustion chamber. The spark plugs ignite the air-fuel mixture to initiate the combustion reactions. Each prechamber houses a corresponding spark plug and concentrates the air-fuel mixture in close proximity to the corresponding spark plug. The exhaust lines form an exhaust manifold that provides a path for exhaust gas formed by the combustion reaction to exit the combustion chambers.
