Claims (1)
応じて吸入空気流路を制御する吸気制御弁を配置
し、機関回転数が予め定められた回転数以上のと
きに吸気制御弁を全開するようにした内燃機関に
おいて、機関回転数が上記予め定められた回転数
よりも低いときに機関運転状態を予め定められた
第１の負荷よりも低い低負荷運転と、該第１負荷
よりも高く予め定められた第２の負荷よりも低い
中負荷運転と、該第２負荷よりも高い高負荷運転
とに分割し、機関負荷が上記第１負荷よりも低い
か又は第２負荷よりも高いときに上記吸気制御弁
を閉弁すると共に機関負荷が上記第１負荷と第２
負荷の間にあるときには上記吸気制御弁を全開せ
しめるようにした内燃機関の吸気制御装置。 An intake control valve that controls the intake air flow path according to the engine load and engine speed is placed in the engine intake passage, and the intake control valve is fully opened when the engine speed exceeds a predetermined speed. In the internal combustion engine, when the engine rotation speed is lower than the predetermined rotation speed, the engine operating state is changed to low load operation lower than a predetermined first load and predetermined higher than the first load. The engine load is divided into medium load operation, which is lower than the second load, and high load operation, which is higher than the second load, and when the engine load is lower than the first load or higher than the second load, When the intake control valve is closed, the engine load is changed to the first load and the second load.
An intake control device for an internal combustion engine, wherein the intake control valve is fully opened when the load is on.
