| 摘要 |
A control apparatus of a multi-cylinder engine (10) of this invention includes branching intake ducts (43A-43D), a plurality of cylinders (12A-12D), a surge tank (42), a impulse charger (50) which charges impulse to each cylinder (12A-12D) at each halfway point in intake stroke, a crank angle detecting means (66), an accelerator pedal position detecting means (68), the interconnection channel (61) connected to the branching intake ducts (43A-43D), VIS valves (63), and a control means (100) which opens the valve mechanism (63) to disconnect the interconnection passageway (61) from the intake ducts (43A-43D) when the engine (10) is in a high-load region and closes the valve mechanism (63) to interconnect the interconnection passageway (61) with the intake ducts (43A-43D) when the engine (10) is in a part-load region under engine driving conditions where a range of engine speed is a level at which the impulse charger is pre-programmed to be operated. |
