<p>To effectively reduce operation noise generated by vibration of the fuel injection valve(44) with a fuel injection valve installation structure of an engine. In the structure, an installation hole (45) is formed in an engine component member (13F, 13R) that constitutes a part of an engine. The installation hole (45) has an annular shoulder portion (45c), which is formed in the middle portion thereof, and which faces the exterior side. The fuel injection valve (44) is held between the annular shoulder portion (45c) and a supporting member' (46) attached to the engine component member. First damper means (47) with high vibration-damping properties is set between an annular shoulder portion (45c) and a fuel injection valve (44), and second damper means (48) with high vibration-damping quality is set between a supporting member (46) and the fuel injection valve (44).</p> |
