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

Internal combustion engine

Provided are a combined machining apparatus and a combined machining method capable of performing machining with higher accuracy and at a high speed. The apparatus has a stage unit; a mechanical machining unit including a mechanical machining head having a tool configured to machine a workpiece; a laser machining unit including a laser machining head configured to emit laser for machining the workpiece; a moving unit; and a control unit that controls the operation of each unit, in which the laser machining head has a laser turning unit that turns laser relative to the workpiece, and a condensing optical system that focuses the laser turned by the laser turning unit, and a position at which the workpiece is irradiated with the laser is rotated by the laser turning unit.

Combined machining apparatus and combined machining method

A ship powered by an internal combustion engine () and an electric motor () connected to a propeller () powered by surplus electric power obtained by a thermal discharge recovery system has a controller including a feedback control section for controlling a base amount of fuel injected to the internal combustion engine () based on the difference between the target number of rotation of the propeller given by the operator and the real number of rotation, and a feed-forward control section having a means () for calculating an overall power output and a means () for calculating a correction in the amount of fuel injected to the internal combustion engine based on the overall power output and the number of rotation of the propeller. The base amount of fuel is corrected by subtracting the correction obtained by the feed-forward section from the base amount of fuel calculated by the feedback control section whereby preventing a rapid change in the speed of the ship due to rapid change in ship loads.
