摘要： PROBLEM TO BE SOLVED: To prevent deterioration in a drivability while improving response of a supercharger by setting a timing lag until opening control is started to an opening/closing control valve, and delaying opening control of the opening/ closing valve for a prescribed time by control means. SOLUTION: In an engine with a supercharger, a throttle valve 6 is arranged on the way of an air feed passage 4 arranged downstream from a supercharger. A bypass passage 8 is arranged to bypass a throttle valve, and an opening/ closing control valve 10 is arranged on the way of the bypass passage 8. In the case where the opening/closing control valve 10 is opened at the time of deceleration and the throttle valve 6 is bypassed, a time lag until opening control is started is set to the opening/closing control valve 10, and opening control of the opening/closing control valve 10 is delayed for a prescribed time by control means 12. It is thus possible to eliminate disorder feeling in a series of motions from an accelerating operation to a brake operation while improving response of the supercharger, and it is also possible to prevent deterioration of drivability.

摘要： PROBLEM TO BE SOLVED: To separately manufacture a gear of each phase to decrease manufacturing cost, and unrequire the entire exchange when one gear is damaged by a method wherein a specified phase gear is combined with a plurality of respective phase gears to form integrally to constitute a detection gear structure. SOLUTION: When a crank shaft 26 rotates, by rotation of A.B phase gear 48-1, U phase gear 48-2, V phase gear 48-3 and W phase gear 48-4, a magnetic type sensor 24 detects a waveform of each phase in correspondence to an A phase, a B phase, a U phase, a V phase and a W phase. A control part controls a motor 14 by this signal wave. The A.B phase gear 48-1, U phase gear 48-2, V phase gear 48-3 and W phase gear 48-4 are combined with each other to form integrally to constitute a detection gear structure 22. Therefore, respective phase gears 48 can be separately manufactured, and manufacturing cost is decreased, and when one gear is damaged, it is possible to exchange only the damaged gear without exchanging all the gears.
