Abstract

A saddle-ridden vehicle includes: an engine; a clutch which enables or disables motive power transmission between a crankshaft provided in the engine and a transmission mechanism; a turbocharger which compresses air for burning to be supplied to the engine; and a throttle device which adjusts a rate of air supply to the engine by controlling an opening angle of a throttle valve using a drive motor, the turbocharger includes a turbine unit which is driven by exhaust gas of the engine and a compressor unit which compresses air receiving drive force of the turbine unit; the clutch is disposed at one side, in a vehicle width direction, of the engine; and the compressor unit and the drive motor are disposed at the other side of the engine in the vehicle width direction.

First claim

What is claimed is:

1. A straddled saddle vehicle comprising:
an engine;
a clutch which enables or disables motive power transmission between a crank shaft provided in the engine and a transmission mechanism;
a turbocharger which compresses air for burning to be supplied to the engine; and
a throttle device which adjusts a rate of air supply to the engine by controlling an opening angle of a throttle valve using a drive motor, wherein:
the turbocharger comprises a turbine unit which is driven by exhaust gas of the engine and a compressor unit which receives a drive force of the turbine unit to compress air;
the clutch is disposed at one side, in a vehicle width direction, of the engine; and
the compressor unit and the drive motor are disposed at the other side of the engine in the vehicle width direction.

2. The straddled saddle vehicle according to claim 1 , wherein: the turbocharger is disposed in front of the engine; and the drive motor is disposed in the rear of the engine.

3. The straddled saddle vehicle according to claim 2 , wherein:
the engine comprises a cylinder which is erected from a top portion of a crank case which houses the crank shaft;
the turbocharger is disposed in front of the cylinder; and
the clutch and the drive motor are disposed in the rear of the cylinder.

4. The straddled saddle vehicle according to claim 3 , wherein:
the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges the exhaust gas of the engine to the outside;
the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;
the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and
the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.

5. The straddled saddle vehicle according to claim 2 , wherein:
the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges exhaust gas of the engine to the outside;
the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;
the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and
the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.

6. The straddled saddle vehicle according to claim 1 , wherein:
the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges the exhaust gas of the engine to the outside;
the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;
the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and
the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.
