Combustion Pre-Chamber Assembly Including Fluidic Oscillator

摘要

A combustion pre-chamber assembly for a reciprocating internal combustion engine includes a body that defines a combustion pre-chamber, a plurality of orifices that extend through the body and effect fluid communication between the combustion pre-chamber and a main combustion chamber of the reciprocating internal combustion engine, a fuel inlet conduit, and a fluidic oscillator flow path with an oscillator inlet in fluid communication with an outlet of the fuel inlet conduit, and an oscillator outlet in fluid communication with the combustion pre-chamber. An ignition device is operatively coupled to the combustion pre-chamber. The fluidic oscillator flow path includes a plurality of oscillator conduits fluidly coupled to one another in parallel. Each oscillator conduit effects fluid communication between the oscillator inlet and the oscillator outlet.
