Abstract

[Problems to be solved] The present invention provides an internal combustion engine equipped with an electrical power generating member which can efficiently convert vibration energy to electrical energy even when the internal combustion is idling and minimize space occupied by rectifier and other power circuit components.
[Solution] The internal combustion engine 11 of a road vehicle includes an electrical power generating member 52 provided in a fixing bolt 26 for fixing a camshaft support member 25 for supporting a camshaft 20 and subjected to the motion of the camshaft 20 and a power storage device 152 for storing electrical power generated by the electrical power generating member 52 in response to the motion of the camshaft 20.

First claim

1 . An internal combustion engine of a road vehicle, which is an internal combustion engine equipped with an electrical power generating member,
wherein the electrical power generating member is provided in a passive member subjected to motion of an actuating member constituting a component of the internal combustion engine and the electrical power generating member is constituted to generate electrical power in response to the motion of the actuating member and store the generated electrical power in an electrical storage device, wherein the actuating member is constituted by a camshaft, and the passive members are constituted by a camshaft support member for supporting the camshaft and a fixing bolt for fixing the camshaft support member and wherein the electrical power generating member is disposed in the fixing bolt.

2 . An internal combustion engine of a road vehicle equipped with an electrical power generating member in accordance with claim 1 , which further comprises a valve serving as the actuating member constituting a component of the internal combustion engine and a valve seat serving as the passive member subjected to motion of the valve, and
wherein an electrical power generating member is provided in the valve seat o generate electrical power in response to motion of the valve.

3 . An internal combustion engine of a road vehicle equipped with an electrical power generating member in accordance with claim 2 , which further comprises a biasing member serving as the actuating member, which assists a reciprocating movement of the valve and constitutes a component of the internal combustion engine, and a passive portion of the biasing member subjected to motion of the biasing member and serving as the passive member,
wherein an electrical power generating member s provided in the passive portion of the biasing member to generate electrical power in response to motion of the biasing member.
