Intake device using pulsating wave of engine

摘要

The present invention generates a pulsating wave corresponding to the rotational speed of the engine in the surge tank of the intake apparatus for supplying the outside air to the inside of the engine to improve the suction efficiency of the air flowing into the engine and at the same time achieve a stable operating state of the engine. An intake apparatus using a pulsating wave of an engine, which includes a surge tank (10) for intake of air and temporarily stored therein, and an intake manifold (20) branched from the surge tank (10) and connected to each combustion chamber (31). In the engine intake device, a sound wave generator 40 for generating sound waves in the surge tank 10 is formed, the sound wave generator 40 is connected to the ECU 50 and the number of revolutions in the engine 30 In response to this, sound waves were generated.
