Abstract
An internal combustion engine includes: an engine body (10) having at least one cylinder; and an air-supply manifold (4) including an adjustment pipe (12). The length of the adjustment pipe is set so that a first pressure wave (14A) propagating from the air-supply manifold toward the adjustment pipe and a second pressure wave (14B) propagating from the adjustment pipe toward the air-supply manifold have opposite phases from each other at the cylinder.

1-10. (canceled)
An internal combustion engine for power generation, comprising:
- an engine body having at least one cylinder;
- an air-supply pipe connected to the at least one cylinder via an air-supply manifold;
- and
- an adjustment pipe having a predetermined length and extending from the air-supply manifold,
- wherein the predetermined length is set so that a first pressure wave propagating from the air-supply manifold toward the adjustment pipe and a second pressure wave propagating from the adjustment pipe toward the air-supply manifold have opposite phases from each other, in at least a part of the at least one cylinder, and
- wherein the predetermined length is set on the basis of an air-supply temperature or an air-fuel mixture composition at the time of a rated output of the engine body.
