With this configuration, in the low-speed operating range of the engine, large resonant supercharging can be achieved by the action of both the primary and secondary surge tanks and the connecting pipe that connects the two surge tanks. At the same time, inertial supercharging from the primary surge tank is also obtained supplementarily, resulting in extremely large dynamic supercharging as a whole. In addition, in the high-speed operating range of the engine, the above-mentioned resonance supercharging decreases, but in this case, the low level of resonance supercharging is compensated for by the extremely large inertia supercharging from the secondary surge tank, resulting in a large overall dynamic This will result in a more efficient supercharging.
