ABSTRACT:
An intake system of a multi-cylinder interval combustion engine including a common inlet duct, first and second resonating ducts branched from the downstream end of the inlet duct, first and second resonating chambers leading from the first and second resonating ducts, respectively, a plurality of first intake ducts for connecting the first resonating chamber to a first group of cylinders, respectively, having ignition timings set not to come adjacent to each other, respectively, a plurality of second intake ducts for connecting the second resonating chamber to a second group of cylinders, respectively, having ignition timings set not to come adjacent to each other, a common intake chamber capable of communicating with both the resonating chambers through communication ports which can be closed by valves, and an actuator for opening and closing the valves at least in response to the engine revolutions. A valve operating system is provided to control at least the closure timing of the intake valves at least in response to the engine revolutions.
