F02B27/0252 - CPC Classification

Classification description:

Use of kinetic or wave energy of charge in induction systems, or of combustion residues in exhaust systems, for improving quantity of charge or for increasing removal of combustion residues the systems having variable, i.e. adjustable, cross-sectional areas, chambers of variable volume, or like variable means characterised by the means generating the charging effect; Plenum chambers; Resonance chambers or resonance pipes Multiple plenum chambers or plenum chambers having inner separation walls, e.g. comprising valves for the same group of cylinders
