Abstract
This supercharger for a motorcycle is driven by power of a crankshaft of a combustion engine, and compresses intake air to be supplied to the combustion engine. The supercharger has an impeller of a centrifugal type, and an intake air control valve is disposed on the upstream side of the impeller of the supercharger with respect to a flow direction of the intake air. The intake air control valve is disposed so as to face a suction port of the supercharger in the flow direction of the intake air. The intake air control valve adjusts the amount of the intake air flowing into the impeller, and in addition, provides a preswirl to the intake air flowing into the impeller.
Claims20
A combustion engine air intake system in a motorcycle,
- the combustion engine air intake system comprising:
- a supercharger configured to be driven by power of a combustion engine of the motorcycle and compress intake air to be supplied to the combustion engine;
- and
- an intake air control valve disposed on an upstream side of an impeller of the supercharger with respect to a flow direction of the intake air, and configured to adjust an amount of the intake air flowing into the impeller, wherein
- the intake air control valve includes a plurality of valve bodies, the valve bodies being arranged in a circumferential direction, and
- the intake air control valve is disposed so as to confront an inlet of the supercharger with respect to the flow direction of the intake air.
A control system for controlling a supercharger for a combustion engine of a vehicle, which supercharger is driven by power from the combustion engine and compresses intake air to be supplied to the combustion engine, the control system comprising:
- an intake air control valve disposed on an upstream side of the supercharger with respect to a flow direction of the intake air;
- and
- an intake air amount controller configured to control the intake air control valve so as to decrease an amount of the intake air when a predetermined output excess condition has been satisfied, wherein
- the intake air control valve includes a plurality of valve bodies, the valve bodies being arranged in a circumferential direction.
An air intake control unit disposed at an inlet of a supercharger which compresses intake air for a combustion engine, the air intake control unit comprising an intake air control valve in which a plurality of variable vanes are radially disposed relative to an axial direction of the valve, wherein
- the intake air control valve includes a valve casing which covers the variable vanes,
- the variable vanes are each set such that a mounting angle about a radial axis of the valve is adjustable in a state where a root portion of the variable vane and a tip end portion of the variable vane are supported, and
- an area of the variable vanes, which area blocks an opening of the valve casing, is changed by adjusting the mounting angle of the variable vanes.
