    摘要： An engine intake system including an intake passage opening to the combustion chamber through an intake port having an intake valve. A control valve is provided in the intake valve for cyclically opening the intake passage. Upstream the control valve, the intake passage is provided with a tank which functions to reverse the negative pressure propagated from the control valve into a positive pressure which is then transmitted to the combustion chamber to increase the intake charge. A timing control mechanism is provided for retarding the opening timing of the control valve in a low speed, high load engine operation.

    摘要： An intake system for a multiple-cylinder engine has a main intake passage open to the atmosphere at its upstream end, a plurality of discrete intake passages which communicate the respective cylinders with the main intake passage by way of intake ports, and a circular passage which is communicated with the cylinders. The circular passage is adapted to propagate pressure waves generated by the intake strokes without reflecting the pressure waves, and is provided with a valve which opens the circular passage to permit propagation of the pressure waves in a predetermined high engine speed range. The length of the circular passage is selected so that the pressure waves resonate in the predetermined high engine speed range.

    摘要： An engine is provided with a mechanical supercharger which is disposed in an intake passage of the engine and is driven by the output power of the engine. The supercharger is connected to and disconnected from the output power of the engine by a clutch. The engine has intake and exhaust valves which are opened and closed with an overlap time. A valve timing changing mechanism changes the overlap time in order to change the amount of air communicated between the intake and exhaust ports. A controller controls the valve timing changing mechanism and the clutch so that the amount of air communicated between the intake and exhaust ports is reduced and the supercharger is disconnected from the output power of the engine and does not operate when the operating condition of the engine is in a first operational range in which the amount of intake air is not more than a first preset value, the former is increased and the latter is connected with the output power of the engine so as to operate when the operating condition of the engine is in a second operational range in which the amount of intake air is not less than a second preset value which is larger than the first preset value, and the former is increased and the latter is disconnected from the output power of the engine when the operating condition of the engine is in a third operational range in which the amount of intake air is between the first and second preset values.
