Abstract

An arrangement structure of an electrically-driven actuator is used in a variable valve operating mechanism capable of adjusting an operation of a valve of an engine. A part of the electrically driven actuator exposed to the outside of the engine is arranged at a position shifted in a car width direction with respect to an exothermic body provided at a periphery of the engine.

Claims (33)

1. An arrangement structure of an electrically-driven actuator to be used in a variable valve operating mechanism capable of adjusting an operation of a valve of an engine, wherein

the engine is provided with a transfer mechanism for transferring rotation of a crankshaft to a camshaft;

a part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position shifted in a car width direction with respect to an exothermic body provided at a periphery of the engine;

at least a portion of the electrically-driven actuator is arranged in a space in which the transfer mechanism is accommodated in the engine; and

a hood inclined to rise from a front side to a rear side of the car is arranged above the part.

2. The arrangement structure of an electrically-driven actuator according to claim 1 , wherein

the part of the electrically-driven actuator exposed to the outside of the engine is positioned on the opposite side of a transmission on the engine.

3. The arrangement structure of an electrically-driven actuator according to claim 1 , wherein

the part of the electrically-driven actuator exposed to the outside of the engine is arranged on a side surface of the engine at a position at which the actuator does not overlap the radiator core in a back-and-forth direction of a car body when the engine is arranged in an engine room.

4. The arrangement structure of an electrically-driven actuator according to claim 1 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine auxiliary machinery and overlaps the engine auxiliary machinery, when the engine is arranged in an engine room.

5. The arrangement structure of an electrically-driven actuator according to claim 2 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine auxiliary machinery and overlaps the engine auxiliary machinery, when the engine is arranged in an engine room.

6. The arrangement structure of an electrically-driven actuator according to claim 2 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine bracket employed to attach the engine in an engine room and overlaps the engine bracket when the engine is arranged in the engine room.

7. The arrangement structure of an electrically-driven actuator according to claim 2 ,

wherein

the engine is provided with an intake manifold and an exhaust manifold, and

the electrically-driven actuator is arranged separate from the intake manifold and the exhaust manifold in a crankshaft axial direction.

8. The arrangement structure of an electrically-driven actuator according to claim 3 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine auxiliary machinery and overlaps the engine auxiliary machinery, when the engine is arranged in an engine room.

9. The arrangement structure of an electrically-driven actuator according to claim 3 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine bracket employed to attach the engine in an engine room and overlaps the engine bracket when the engine is arranged in the engine room.

10. The arrangement structure of an electrically-driven actuator according to claim 3 ,

wherein

the engine is provided with an intake manifold and an exhaust manifold, and

the electrically-driven actuator is arranged separate from the intake manifold and the exhaust manifold in a crankshaft axial direction.

11. The arrangement structure of an electrically-driven actuator according to claim 1 ,

wherein the part of the electrically-driven actuator exposed to the outside of the engine is arranged at a position at which the part is above an engine bracket employed to attach the engine in an engine room and overlaps the engine bracket when the engine is arranged in the engine room.

12. The arrangement structure of an electrically-driven actuator according to claim 1 ,

wherein

the engine is provided with an intake manifold and an exhaust manifold, and

the electrically-driven actuator is arranged separate from the intake manifold and the exhaust manifold in a crankshaft axial direction.
