| description | An intake system for a multi-cylinder internal combustion engine having an intake manifold that is made up of a common intake passage and separate intake passages that branch off from the common intake passage and connect to intake ports of the engine cylinders. An upstream throttle valve is located in the common intake passage. Downstream throttle velves located in the separate branched intake passages near the intake ports. A controller controls intake air actually introduced into the cylinder by actuating the downstream throttle valves to throttle down, smaller than the upstream throttle valve in a light engine load range and by actuating the upstream throttle valve to throttle down smaller than the downstream throttle valves in a heavier engine load range. |
