摘要： A control device for an engine variably controls electricity power supplied to a motor driving a valve to open or close a fluid passage based on operation condition of the engine. The valve has a full close range in which the fluid passage is closed. When the engine has low load and low rotation, the control device stops supplying the electricity power to the motor, and the valve is held at a neutral position where a biasing force of a first biasing portion and a biasing force of a second biasing portion are balanced. The neutral position is set within the full close range.

摘要： A supercharger includes a rotative member that is rotated by an electric motor eccentrically to the center of a casing. A valve is rotatably supported by a periphery of the rotative member. The valve is capable of making contact with a periphery of the rotative member so that an inner periphery of the casing and an outer periphery of the rotative member define an annular space therebetween in a full opening position. The valve is capable of making contact with the inner periphery of the casing to partition the annular space into multiple variable space in a full closing position. Opening degree of the valve is controlled in an intermediate position between the full closing position and the full opening position in accordance with an accelerator position in a low-load operation.

摘要： An intake system for an engine includes a duct defining an intake passage therein, and a cantilevered valve including a valve main body opening/closing the intake passage, a shaft supporting the body, and a valve extension portion. The duct includes a reduced passage portion between the duct and the body when the body is in a fully closed position, a recess accommodating the body and the extension portion when the body is fully opened, and a pressure introduction passage formed between the duct and the body when the body is fully closed, and communicating with a space between the body and the extension portion when the body is fully closed. The extension portion includes a sealing part. The duct and the sealing part define a clearance therebetween when the body is fully closed. The clearance has a smaller sectional area than the reduced passage portion.

摘要： A rotation angle detecting device includes a magnet (4), a magnetic substance unit (5), and a non-contact magnetic detection element (7). The magnet (4) rotates with an object to be measured and includes two ends magnetized so as to have opposite polarities. The magnetic substance unit (5) forms a predetermined air gap with the two ends of the magnet (4) and is divided into magnetic members (6) so as to provide plane symmetry with respect to a vertical plane perpendicularly crossing a rotational center axis of the magnet (4) to form a magnetic detection gap (9) by the division. The non-contact magnetic detection element (7) is provided in the magnetic detection gap (9) between the magnetic members (6) so as to output a signal corresponding to a density of a magnetic flux passing through the magnetic detection gap (9). The rotation angle of the object to be measured is detected based on the output signal from the magnetic detection element (7). The magnetic members (6) include reverse warp parts (34) so that the air gap suddenly increases when the magnet (4) rotates at a predetermined rotation angle from a state where the air gap is minimum in a direction in which the air gap increases.

摘要： An air intake device for an engine includes a duct having therein a first air flow passage, a housing having therein a second air flow passage, a rotary valve having a valve plate. A block of the housing, which conducts intake air to an intake port of a cylinder head, has a circular opposed surface that follows a shape of a curved surface portion of the valve plate. Moreover, the block of the housing has a protrusion that protrudes toward an upstream side of the second air flow passage in an air flow direction so as to contact a duct protrusion of the duct. Therefore, a localized flow of the intake air, which has flowed into the second air flow passage from an opening of the first air flow passage, can be restrained from spreading, and a flow rate of the localized flow can be restrained from slowing down.
