Title:
吸気制御装置
Document Type and Number:
Japanese Patent JP7006546
Kind Code:
B2
Abstract:
To provide an intake control device capable of suppressing occurrence of surge caused by influences of intake pulsation of an engine, without reducing a pressure ratio across a compressor.SOLUTION: An intake control device 10 comprises: an accelerator opening sensor 31; an engine rotation speed sensor 32; a boost pressure sensor 33 for detecting an intake pressure of an engine; a target intake pressure setting section 42 for setting a target intake pressure; a storage section 43 for storing a preset opening limitation parameter so as to limit an opening of a throttle valve 11 further than a full opening under a load and a rotation speed in which a compressor 18 is actuated within an intake pulsation surge range that is preset on a characteristic diagram representing characteristics of the compressor 18; and an intake control section 44 for controlling the throttle valve 11 so as to limit the opening of the throttle valve 11 in accordance with the opening limitation parameter and controlling a turbosupercharger 17 in such a manner that the intake pressure becomes the target intake pressure.SELECTED DRAWING: Figure 1
