Title:
並列二気筒内燃機関のバランサ装置
Document Type and Number:
Japanese Patent JP5847688
Kind Code:
B2
Abstract:
A device is provided for reducing first cylinder vibratory force (F1) and second cylinder vibratory force (F2) which are generated when a crankshaft (5) is rotated, in a parallel twin cylinder internal combustion engine in which a crankshaft (5) is provided with a first crankpin (5PL) and a second crankpin (5PR) at a predetermined phase angle (¸) and a cylinder block (8) is formed with a first cylinder (#1) and a second cylinder (#2). In the device, a straight line for bisecting an angle formed between the first cylinder (#1) vibratory force (F1) and the second cylinder (#2) vibratory force (F2) is defined as an angle bisector (DL), force with the first cylinder (#1) vibratory force (F1) and the second cylinder (#2) vibratory force (F2) resolved in a direction parallel to the angle bisector (DL) is defined as an inertial force component, force with the first cylinder vibratory force (F1) and the second cylinder vibratory force (F2) resolved in a direction parallel to a plane perpendicular to the angle bisector (DL) is defined as a couple component, an inertial force balancer is provided for generating force facing the inertial force component, and a couple balancer is provided for generating force facing the couple component.
