INTERNAL COMBUSTION ENGINE AND IGNITION COIL
First Claim
1. An internal combustion engine including an internal combustion engine main body forming a plughole therein;
- and a pillar shaped ignition coil to be inserted in the plughole;
wherein an electromagnetic wave element is provided on a head part of the one end side of the ignition coil for outputting electromagnetic waves to be emitted to the combustion chamber of the internal combustion engine main body; and
the internal combustion engine comprises a plurality of supporting components that support the ignition coil at a nodal point of the characteristic vibration mode of vibration that occurs in the ignition coil accompanied by the vibration of the internal combustion engine main body when an attaching part in the other end of the ignition coil is attached to the ignition plug positioned in the combustion chamber side of the plughole.

Abstract
The internal combustion engine has an internal combustion engine main body and a substantially columnar ignition coil. A head part at one end of the ignition coil is provided with an electromagnetic wave element for outputting electromagnetic waves irradiated into a combustion chamber of the internal combustion engine main body, and a plurality of supporting components are provided for supporting the ignition coil when an attaching part at the other end of the ignition coil is attached to a spark plug, the supporting components supporting the ignition coil either at or near a nodal point in a characteristic vibration mode of vibration occurring in the ignition coil along with vibration of the internal combustion engine main body. The ignition coil is not supported on the side toward the head part relative to the support member nearest the head part.
