ABSTRACT:
A four cylinder in-line engine is disclosed with a secondary balancer system, wherein at least one pair of balancer elements are arranged substantially at an identical horizontal distance from the longitudinal axes of the engine cylinders and on lines which are substantially parallel to the plane of the longitudinal axes. The distance taken between the axes of the paired balancer elements in the direction of the cylinder axes is determined at such desired values as to satisfy the engine usage and design. The paired balancer elements are rotated in the opposite directions to each other with a speed of rotation twice as high as that of the engine crackshaft, such that the lower balancer element is rotated in the opposite direction to that of the engine crackshaft.
