摘要： An intake control apparatus is configured to control a variable valve operating mechanism and an opening degree of a throttle valve. The variable valve operating mechanism varies the valve lift characteristic of the intake valves to control the intake air amount into the cylinders of the engine. The throttle valve produces a negative pressure inside the collector, but in a valve control region including medium loads, the pressure inside the collector is fixed at a weak negative pressure and the intake air amount is controlled by varying the valve lift characteristic of the intake valves. In an internal EGR priority region of low loads, the negative pressure is strengthened somewhat and the lift/duration of the intake valves is increased. When the engine is cold, the negative pressure is adjusted to be close to atmospheric pressure and the lift/duration of the intake valves is reduced.
