摘要： An induction system for use in a V-shaped engine having a forward bank and a rearward bank each provided with a row of cylinders, the induction system includes intake runners individually extending from the cylinders of each bank, the intake runners being convergedly connected at upstream end portions respectively. To upstream ends of thus converged connection portions are connected common intake passages, which are connected to a junction portion at a further upstream side, whereby the respective common intake passages are connected. The lengths of the intake runners from the cylinders up to a center of the converged connection portion are set equal to one another. The respective converged connection portions are arranged vertically above the rearward bank. A communicating passage is provided for communicating the center portions of the respective converged connection portions with each other. In the communicating passage is provided a valve for opening or closing the communicating passage according to an engine speed. In this induction system, the dynamic effects of induction can be efficiently utilized in a wide range of engine speed in a relatively simplified construction. In addition, an intake manifold can be arranged in such a manner as to make the size of the engine smaller.

摘要： In an engine induction system, a drive frequency f1 of an ISC valve 13 for duty control and a characteristic frequency f2 of an intake passage between an air cleaner 8 and a throttle valve 11 are set so as to obtain a relationship: (3/4)f1.ltoreq.f2.ltoreq.(5/4)f1. In this set system, a resonance chamber 17 is connected to the intake passage between the air cleaner 8 and the throttle valve 11 to thereby deaden the vibration caused by the driving of the ISC valve 13. Accordingly, the engine induction system is allowed to prevent the amplification of the vibration accompanying the actuation of the ISC valve so as to prevent the deterioration of the detection accuracy of an airflow meter while being allowed to meet requirements such as an improvement in the responsiveness when the ISC valve disposed in an ISC pipe is duty controlled.

摘要： In the present invention, in addition to a main throttle valve which is conventional, a sub-throttle valve for exclusive use of a mechanical supercharger is provided. By this sub-throttle valve, a flow rate of intake air is throttled by a fixed amount when the mechanical supercharger is switched from a non-connected state to a connected state. This makes it possible to prevent supercharged air from being bypassed to upstream of the supercharger through a bypass and also prevents generation of air intake noises. Moreover, in the case where the mechanical supercharger is of a type involving interior compression, at the time of the switching operation torque shock can be prevented and controllability of engine output by an accelerator pedal is improved.
