At most four cylinders (1, 2, 3; 4, 5, 6) having successive valve control times which at most slightly overlap are each connected by means of pipes (10) to one of two resonance volumes (11, 12) The resonance volumes are inter- connected by a resonance passage (13) and form in conjunction therewith a charging system which is tuned to resonance, The fresh air infeed to such system is accomplished by means of a pipe (14) which is constructed such that its natural vibration frequency is not equal to the resonance vibration frequency of the tuned system. One of the resonance volumes (32), Figures 4 and 5 (not shown), may be formed by a charge air cooler. <IMAGE> |
