Abstract
An internal combustion reciprocating engine includes an intake gas conduit system for supplying each engine cylinder with intake gas. Maximum four engine cylinders whose suction cycles are in a substantially non-overlapping relationship with one another form a cylinder group. The intake gas conduit system has a feed resonator vessel communicating with the intake opening of each cylinder of the cylinder group, a dampening vessel having an intake gas inlet opening and a feed resonance tube maintaining communication between the feed resonator vessel and the dampening vessel. The feed resonator vessel and the feed resonance tube form a first oscillating system in which intake gas oscillations are generated by the effect of periodic suction cycles of the cylinders forming the cylinder group. The intake gas conduit system further has a closed resonator vessel and an equalizing resonance tube maintaining communication between the dampening vessel and the closed resonator vessel. The closed resonator vessel and the equalizing resonance tube form a second oscillating system in which intake gas oscillations are generated by the oscillations taking place in the first oscillating system.
