From the time when the intake valve 2 closes, the on-off valve 4 of the pressure accumulation chamber 3 is opened.
A helical flow 8 of air generated in the intake port 1 follows the direction 7 in which the air trapped in the pressure accumulation chamber 3 up to the time when the pressure accumulation chamber 3 closes is released into the intake port 1 by opening the on-off valve 4 of the pressure accumulation chamber 3. An intake port section of a direct injection diesel engine, characterized by being selected in the direction of acceleration.
