INTAKE DEVICE FOR V-TYPE MULTIPLE CYLINDER INTERNAL COMBUSTION ENGINE / HONDA MOTOR CO LTD (PURPOSE) To make the whole of a device compact by mutually crossing distribution pipes of an intake manifold at the intermediate parts thereof, and forming a pipe length switching chamber integrally with the cross part, and while providing pipe length switching valves at a boundary part connecting the distribution pipes and the pipe length switching chamber. (CONSTITUTION) In a V-type multiple cylinder internal combustion engine, a volume enlarging part Bg of which upperstream side communicates with the atmosphere and an intake manifold Mi having distribution pipes 351 -356 , of which upperstream side is connected to the volume enlarging part Bg and the downstream side is connected to cylinder groups Cl, Cr in right and left respectively, are provided. A pipe length switching chamber Cc for communicating the intermediate parts of the each distribution pipe 351 -356 with each other through pipe length switching valves 38l, 38r is provided. In this case, the intermediate parts of the distribution pipes 351 -356 are crossed each other, and the pipe length switching chamber Cc is formed outside of the intake manifold Mi at this cross part. The pipe length switching valves 38l, 38r are located at a boundary of the distribution pipes 351 -356 and the pipe length switching chamber Cc in the intake manifold Mi. |

SUCTION CONTROL METHOD FOR SIX-CYLINDER INTERNAL COMBUSTION ENGINE / HONDA MOTOR CO LTD (PURPOSE) To enhance the volume efficiency in a wide operating range of an engine by opening an closing under control an opening/closing valve, which can put a pair of resonance chambers in mutual communication, and also a pipe length changeover valve which can put the middle part of a distribution pipe in communication to a pipe length changeover chamber. (CONSTITUTION) A pair of resonance chambers Cr-l, Cr-r are installed, which can be in communication with each other though an opening/closing valve 23 and whose upstream side is leading to the atmosphere via a throttle valve 20. The middle parts of distribution pipes 351 -356 to connect the group of cylinders left and right Cl, Cr, whose suction strokes are not continued, to respective resonance chambers Cr-l, Cr-r shall be capable of being leading to a pipe length changeover chamber Cc through pipe length changeover valves 38l, 38r. The opening/ closing valve 23 and pipe length changeover valves 38l, 38r are both closed in the low speed operating range of the engine, while only the opening/closing valve 23 is opened in the middle speed operating range, and the opening/closing valve 23 and pipe length changeover valves 38l, 38r are both opened in the high speed operating range. This will constitute a resonant supercharge system in the low speed operating range and an inertia supercharge system for large and short pipe length in the middle and high speed operating ranges, so that the volume efficiency can be enhanced in a wide operating range of the engine. |
