The switching tube system uses the DISA valve to use various gas dynamic effects for self-charging. The 2-stage system in the M64 optimizes the filling of the cylinder in the lower and upper speed ranges through resonance charging and swing tube charging. Even without a mechanical charger such as an exhaust turbocharger or compressor, the filling can be improved through self-charging.
